I Had a Home In 1982 Chapter 499

   Chapter 499 498. Watching the sea and listening to Taolin, emergency rescue

  The leaders discovered early in the morning that there were earthen stoves and freshly burned ashes in the pine forest.

   They sent a security team to patrol the jungle.

  Huang Zhiwu and others were just fishermen after all, and they were not careful enough. They thought that they would not be discovered by the leaders by secretly roasting two rabbits.

   After all, there are too many things for leaders to manage and worry about.

   But the leaders have more people, send some people into the pine forest to carefully search for two circles, won't they find everything?

  The security team found traces of the fire yesterday, but no one was caught.

   In this way, in order to avoid stunned snakes, they first stood still, that is, they arranged for people to watch in the pine forest.

   When Huang Zhiwu and the others quarreled with Changhai Commune because of the rabbit trap, the members of the security team saw the opportunity and went to report the news to the leader, which led them to come over.

   After the leaders arrived, they easily put the words out.

After the    phrase came out, the atmosphere at the scene became very tense.

   The people from the Changhai Commune opposite heard that Huang Zhiwu and his group had already roasted rabbits in the pine forest yesterday, so they quickly stepped back.

   Don't even want the rabbit.

   just waiting to watch the fun.

   Now there is indeed a lot of fun to watch.

   Dong Hongqi, the cadre in charge of their commune, hated that iron could not be made of steel, and pointed at Huang Zhiwu and scolded: "What's the matter with you, old Huang?

   "The drafter, did you take my words on deaf ears? I repeatedly emphasized, emphasized, emphasized that your uncle is not allowed to light a fire in the pine forest, not even to smoke, and you ended up roasting rabbits in it!"

   "Why don't you bake yourself!"

  Huang Zhiwu's mind quickly turned, and he wanted to come up with a reason to whitewash himself, but the leaders were not fools, how could he be fooled?

   In particular, the leaders of the battalion headquarters and the regiment headquarters came, each with an angry expression and a sharp tone.

  Some leaders of the regiment came first before they arrived: "It must be dealt with seriously! The chickens must be killed to warn the monkeys!"

  Huang Zhiwu's face turned pale, as if a donkey's feces had rolled a layer of white face.

  Their members were even more trembling.

  I didn't expect the situation to be so serious!

  Wang Yi saw this and went forward.

  He's ready to go.

  Otherwise, if the leaders convicted Huang Zhiwu and the members of Jinlan Island, and these people confessed their guilt, then it would be useless for him to go out.

   And seeing him coming out to speak, Huang Zhiwu and his group all looked at him eagerly:

  Teacher Wang, help!

  Wang Yi stepped forward and said, "Leader, don't be angry, Captain Huang and the others did set fire to the pine forest, but the fire was not just for roasting rabbits, there were other reasons for this."

   "What else is there? They are going to burn the pine forest?" a regiment leader snapped.

  Wang Yi said: "Yes, they are really going to order pine trees."

   Hearing this, the crowd watching the lively around was taken aback, and someone subconsciously asked: "How did Lao Huang offend Tianya Island?"

   "Did he really do this? I'm a slacker, set fire to the mountain, and sit in the prison! Set the fire to the forest, what's the next sentence?"

   "Broken, Lao Huang is going to jail!"

  Huang Zhiwu and the members around him became anxious when they heard Wang Yi's words.

   Fortunately, Huang Zhiwu is smart and understands Wang Yi. He knows that Wang Yi will not come out and get himself into trouble. There is no reason for this.

   So he deduced that Wang Yi had a backhand, and seeing that the members around him wanted to deny it, he quickly pulled a hand and winked wildly.

  Wang Yi didn't sell anything here. He quickly answered the question and said, "They ordered pine trees to protect this pine forest, but I thought it was too dangerous, so I stopped him."

  Cui Qingzi had a good impression of him and asked, "What do you mean by that? How can he protect this pine forest by ordering pine trees?"

  Wang Yi pointed to the small clumps of yellow-red pine trees in the pine forest and said, "Have you seen those pine trees? They are black pine trees. They were originally dark green, and they shouldn't be this color."

   "Why is this color displayed?"

   "Because they were infected with bugs, a very scary bug, a bug that could destroy an entire pine forest."

   "Pine wood nematodes!"

   Wang Yi said solemnly and loudly.

  Huang Zhiwu grabbed the words he handed over and said quickly: "Yes, yes, those trees are infected! There are many small insects, very scary insects, called, called pine wood nematodes!"

   He knew that Wang Yi would definitely not come out and get in trouble, let alone slander them.

   He knew that Wang Yi had a big move to solve their troubles.

   The leaders frowned: "You comrade, don't make trouble here, don't try to make big news to scare people."

   "What pine wood nematode? How come I didn't see any worms? I tell you, comrade, you're making up lies to exonerate your acquaintances, it's also a crime!"

The cadre in the    county laughed and said, "No, no, how can this be related to a crime? This is a mistake, not a crime."

  Wang Yi said: "I didn't make trouble, and it's not nonsense. If you don't believe me, you can break down the branches of the pine tree that have withered and yellowed and compare them with the branches of normal pine trees. You will definitely find small pests."

   "There are indeed these pests, we have all seen them." Wang Donghu and others supported Wang Yi.

   At this time, some of the laborers who were watching also spoke up.

  The people in Huangtu Township responded very quickly: "Yes, Teacher Wang is really not talking nonsense. There are very small insects on those trees."

   "I don't blame the leaders for not finding it. If you don't look carefully, you can't really see it. The bugs are very small, smaller than a grain of rice."

   "The pine trees that have turned yellow are really dead, we are chopping wood..."

   "Shh! Don't talk nonsense, we are collecting firewood, not splitting trees for firewood!"

  Wang Yi asked someone to chop the branches, and then introduced further: "Mr. Leaders, I'm not talking nonsense or exaggerating, and now this pine forest is indeed plagued by pine wood nematodes."

   "Pine wood nematodes specially infect pine trees. The disease they infect is called pine wood nematode disease, also known as pine wilt disease. They can be said to be the most serious forestry quarantine pests in the world."

   "The pine wood nematode disease caused by them is very troublesome. It affects a wide range, spreads quickly, has a high mortality rate of infected pine trees, and is difficult to control. You'd better notify the city's forestry bureau."

   "Even the leaders of the Forestry Bureau may not know about this pest. It's best to contact the forestry experts in our city, or the experts in Jinling."

   "Last year, this kind of pest and disease occurred in the Sun Yat-sen Mausoleum in Jinling. I saw it in the newspaper and heard it on the radio, and I was very impressed."

   His remarks were quite professional, and he briefly described the harm of pine wood nematode, so the leaders on the scene hesitated.

  Cui Qingzi whispered to them: "This is Teacher Wang Yiwang in our county, the grandson-in-law of our leader Ye. He is very knowledgeable, very reliable, and very respected in our county."

  Wang Yi is quite famous.

  There are also leaders in the city who have heard of his name.

   One of the leaders asked, "Is that the teacher Wang mentioned by Deputy Secretary Chongshan?"

   County leaders nodded.

   In this way, the leaders turned from doubt to belief.

   It happened that there were people from the city's forestry bureau in the leadership team that was rushing to the sea this time, so they asked the militia to call the staff of the forestry bureau over and asked Wang Yi to explain the situation to him.

   This staff member was confused and his eyes were darkened.

   As Wang Yi guessed, he had never heard of the pine wood nematode.

   But the facts speak louder than words:

  The members have chopped down some yellow-red pine trees and sent them to the leaders.

  The split wood is densely packed with many small insects.

   There happens to be a leader who carries a magnifying glass - Wang Yi doesn't know why this leader brings a magnifying glass, but they do.

  The wood was brought over. He took out a magnifying glass from his pocket and stared at Wang Yi for a moment.

  Cui Qingzi knew the reason and explained: "I catch the sea workers to dig the bottom of the sea, and from time to time some antique artifacts will be dug up."

   Wang Yi understood.

  This magnifying glass is for viewing antique artifacts.

   is now used to see pests.

  The leaders saw these pests clearly through the magnifying glass.

  Even though the weather was cold, the pests did not die or hibernate, but were still creeping slowly inside the branches.

  The cadre of the Forestry Bureau took a deep breath after seeing these pests after arriving: "Comrade, are you saying that these pests have caused many black pines to wither and die? And can they destroy this pine forest?"

  Wang Yi said seriously: "Yes, they really can, if left alone, I think the entire black pine forest will be devastated this year."

   "Isn't it a bit alarmist?" The cadre of the Forestry Bureau smiled, "It's impossible for such a powerful pest to appear suddenly, right?"

   Wang Yi said: "They were brought in from abroad..."

"Then why was it brought to our black pine forest?" The cadre of the Forestry Bureau shook his head, "You may not know, comrade, this pest is brought from one environment to another, and will not destroy the new environment at once. Sexual destruction."

   "This is like bacteria or viruses - I don't know if you can understand what I mean, in fact, our bodies are exposed to many kinds of bacteria and viruses every day."

   "But these bacteria and viruses won't do us any good after they enter our body, because we have immunity, and in fact nature has immunity."

  Wang Yi said: "I understand what you mean, I'm a barefoot doctor, and your reasoning in our medicine is called 'to talk about harm without the dose is a hooligan'."

   "Only a few foreign pests come to the local area, and it is difficult to form a stable population, so it is not so easy to cause devastating damage to the local environment."

"But how many of these pests came to us? For example, when someone smuggled wood or wood products ashore, they used this windbreak forest as a cover. As a result, there were a large number of pests in the wood and wood products. Will this lead to Invasion of a swarm of pests?"

   The cadres of the Forestry Bureau were stunned.

   It is possible!

The leader next to    understood what he meant when he saw his reaction, and asked, "Did someone smuggle wood and cause this pest to appear?"

Wang Yi said: "This possibility cannot be ruled out. As far as I know, the proliferation of this pest in foreign countries is because in social and economic activities, pine wood with pine wood nematodes and their products are transported by roads, railways and other different places. Artificial introduction of outbreaks into new areas.”

   "This is called man-made epidemics, and the epidemic wood is circulated through artificial transmission. According to research by foreign experts, nearly 80% of the epidemics in pine wood nematode epidemic areas are caused by the inflow of epidemic wood and its products."

   "Because man-made transmission is not restricted by natural barriers, it spreads quickly, involves a wide range of fields, and is difficult to manage, which can easily bring danger to the natural environment."

  The forestry cadre licked his lips and said, "This comrade is right, he, he is very professional."

  The big guys nodded.

   Wang Yi's words are too professional.

   It's too good-looking.

   is too expert.

   had to believe his words.

  Wang Yi fumbled for his chin—in fact, he wanted to hold his glasses, but unfortunately his eyesight was too good to wear glasses.

   Touching his chin is also very professional. He asked the officials of the Forestry Bureau: "Comrade, I want to ask, is there a lot of beetles in this pine forest?"

  The cadre said: "Yes, there are long beetles in the pine forest, pine brown beetles, spruce flower black beetles, and so on."

  Wang Yi said in a deep voice, "That's right, as you can see, there is a distance between the affected pine trees, and the pine wood nematodes are very small. They are parasitic in the pine trees. How can they spread by themselves?"

   "The distance between these pine trees is not short. Compared with the pine wood nematode, it is a natural barrier. How does it spread from one pine tree to another pine tree and cause damage to the pine forest?"

"I think it is the vector insects that do their accomplices, the long beetle is a vector insect, they carry the pine wood nematode from the diseased wood, and by moving through the woods, they spread the pests to the healthy pine trees and infect the new healthy ones. pine."

  Professional knowledge is incomprehensible, but it sounds interesting.

   Because it's eye-opening.

  Some people are willing to come to catch the sea work because people from all over the world come when they are on the sea work, and they can gossip with each other.

  In the age of no internet and lack of television, gossip information was spread by word of mouth.

   In this way, someone asked Wang Yi with interest: "Mr. Wang, what is a vector insect? Why is the pest related to the beetle again?"

  Wang Yi was about to speak when Cao Yuqin explained it in a simple way.

  : "Vector insects are matchmakers in insects. Our matchmakers are to introduce wives, and insect matchmakers are to introduce a pest or a bacterial virus to other species."

   "Mosquito fleas, for example, are vectors of many bacterial viruses that can transmit bacterial viruses that cause malaria, Japanese encephalitis, dengue, hemorrhagic fever, and yellow fever."

"Tell me the closest to the big guy. From 1958 to 1959, from 1964 to 1965, and from 1971 to 1972, our Jiangnan region cooperated with Shanghai to launch three large-scale mass snail eradication campaigns. This snail is the medium. creatures, they transmit schistosomes."

   The snail eradication campaign aimed at eradicating schistosomiasis impressed everyone present, and the example of the barefoot doctor is very appropriate.

   Everyone knows about this.

   Wang Yi nodded.

   Cao Yuqing's simple and straightforward explanation is not particularly accurate, but he can answer everyone's doubts in just a few sentences.

   A leader of the regiment asked cautiously: "Are there many insects such as beetles in the black pine forest? I have visited the black pine forest several times, and I feel that there are not many beetles in it."

  The cadres of the Forestry Bureau are the grass on the wall.

   Hearing the leader ask this question, he said, "Yes, not much."

  Wang Yi said: "It's not too much, it's normal. You see, there are not many trees infected with pine wood nematode disease in the black pine forest. An adult longhorn beetle can spread hundreds of thousands of pine wood nematodes at most."

   When the big guys heard this, they all gasped.

  Wang Yi continued to explain the knowledge he had read from the materials: "It's like this, longhorn beetles have a hobby for breeding and laying eggs, that is, they give priority to pine boreholes with weaker trees to lay eggs."

"And the pine trees infected with pine wood nematodes will grow weaker, which is an ideal spawning place for the long beetle. The long beetle lays eggs into pupae and then hatches, and the pine wood nematodes in the infected pine trees will invade their respiratory system through the long beetle's stomata. , or attached to the surface of the beetle."

   "This way, when the bulls are flying around in the pine forest, they can spread."

   "After they invade the tree, they will reproduce in large numbers. The nematodes are very small, and can quickly spread to various places with the pine transport tissue, resulting in blocked water transport, reduced transpiration, and -- in short, all kinds of problems."

   "Oh yes, it will also cause the pine tree not to secrete resin!" Wang Yi suddenly thought of a very important point.

   "When the pine tree can't secrete resin, from the outside, the needles will turn green, then turn brown and wither, so it turns yellow-brown or even reddish-brown, and finally the whole tree will die!"

  Wang Yi pointed to the trees that looked especially weird in the white snow for everyone to see: "I just saw that the colors of these trees were not right, so I went into the woods with Captain Huang to understand the situation."

   "Captain Huang has sharp eyes..."

   "The pilot's eyes." Huang Zhiwu quickly seized the opportunity to show his eyes.

  Wang Yi said: "Yes, in short, Captain Huang discovered the pine wood nematode. After he heard me explain the harm of the pine wood nematode, he thought of cutting down all the diseased and withered trees and burning them, so as to eliminate the pest."

The    leader asked: "This is useful?"

  Wang Yi shook his head: "It's useful, but it's a temporary solution, not the root cause. It's winter now, and the pine wood nematode is not active, so it's very likely that some pine wood nematodes have been infected to other trees, but they haven't multiplied."

   "If it is in the active period of spring, summer and autumn, a pine tree infected with pine wood nematode will die in about 40 days at the fastest!"

   Another leader couldn't help but ask: "You're really not being alarmist..."

   "What he said is true." The cadre of the Forestry Bureau thought about it and said quickly, "The yellow-red color of the black pine forest only happened two months ago."

   "It happened to be late autumn and early winter, so after we found it, we thought it was a new change produced by the adult pine tree."

  Wang Yi said: "So, please contact the experts quickly. It is best to contact the experts from the Forestry Bureau in Jinling. They have experience in this area."

  The leaders looked at each other.

   Finally someone said: "I'll report the matter to the leader and listen to his opinion."

   "So, let's stop this matter for now, comrades, hurry back to have breakfast and get ready to go to work, don't dawdle, don't stay in the woods anymore, let alone start a fire in the woods!"

  The matter of burning rabbits in the pine forest on Cam Ran Island was temporarily put on hold.

   After the big guys returned to the camp, Huang Zhiwu quickly handed the rabbit to Wang Yi:

   "Mr. Wang, you really saved our lives today!"

  Wang Yi waved his hand and said, "Captain Huang, you're welcome, we are neighbors and we should help each other."

   "But I also have to say that it's too dangerous for you to start a fire in the pine forest. In winter, the wind is strong and the grass and trees wither. What if there is a fire?"

  Huang Zhiwu smiled bitterly: "Yes, Mr. Wang, what you said makes sense, but we are really careful."

   "We also knew what would happen if we set fire to the forest, so we made a special firebreak when we built the earthen stove..."

   "Okay, don't make excuses for yourself, you made a mistake this time." Wang Xianglai said bluntly.

  Huang Zhiwu had nothing to say, he could only nod his head dejectedly.

  Wang Yi said: "Don't do this in the future. I'm here to help because we are neighbors. Next time you do such a dangerous thing, I'll be the first to report you!"

  Huang Zhiwu said frustratedly: "Teacher Wang, don't worry, I will never do this kind of thing in the future."

   "Thanks for having you this time—by the way, did you just say something about the pine wood nematode just to help us, or did it really happen?"

   Wang Xianglai pointed at him and said, "What are you talking about? Who is Mr. Wang, and what knowledge does he have? How could he be talking nonsense!"

   Others also said: "That's right, you don't believe what Teacher Wang said?"

  Wang Yi said: "Everyone don't make a fuss, but such an important thing is of course true, I can't talk nonsense about this kind of thing!"

  Huang Zhiwu said with a smirk: "It's not that I don't believe Mr. Wang, the main thing is that Mr. Wang, you are really amazing, you know everything, I am the one who admires you today!"

   He wanted to leave the hare to Wang Yi.

  Wang Yi didn't want it.

  22 years have rabbits.

   In fact, hares are not delicious in winter, the fat is consumed a lot, and the meat quality is relatively woody, which is not as good as breeding rabbits.

   Not everything is better wild than farmed.

  Wang Yi's profound knowledge really surprised many people. Many camps around him were discussing the pine wood nematode he introduced and himself.

  The members don't have a broad vision or a large amount of knowledge, but they are not stupid, they are very clever and know the world.

   They all know that Wang Yi spoke with pine wood nematodes to relieve Huang Zhiwu and the laborers of the common people production team:

   "Just like Huang Zhiwu's stupid appearance, what can he understand about foreign pine wood nematodes?"

   "Absolutely, if Huang Zhiwu knew about pine wood nematodes, I would eat a bowl of pine wood nematodes as rice!"

   "Mr. Wang is really a loyal person. It's nice to be friends with him. I'll invite him to dinner tonight."

   "Well, having a friend like Mr. Wang is definitely something to be proud of. I also want to be friends with him, just because I'm afraid that people will look down on our muddy legs..."

   When it was time to go to work, Wang Yi came to save face.

   The surrounding squads are no longer competing with them.

   The leaders of the security team or company headquarters and battalion headquarters used words to stimulate them, and they lay down directly:

   "It's not ashamed to lose to the first row, you don't see who is leading the first row, it's Teacher Wang who is leading the team!"

  Wang Yi's team leader here is in full swing.

   As the morning approached, someone suddenly came to their construction site: "Comrade Wang Yi, Comrade Wang Yi, where is Comrade Wang Yi?"

   "Comrade Wang Yi in a row please stand up quickly, the organization needs you! The organization needs your help!"

  The loud voice wafted over the construction site.

   Several people stopped to look around curiously.

   The phrase 'the organization needs you' is really exciting!

  Wang Yi picked up the cotton-padded coat on the ground and put it on his body. He wiped off his sweat and rushed to the breakwater in two steps and asked, "I'm Wang Yi, what's wrong? It's about pine wood nematodes..."

   "You are Comrade Wang Yi? That's great, hurry up with me." The cadre hurriedly grabbed his arm and led him out.

  Wang Yi asked: "What are you doing? Report the information on pine wood nematode to the leader?"

  The cadre said: "No need to report, the leaders already understand the harm of pine wood nematode."

   "There is a new leader in the city, led by Wei Chongshan, he asked me to come over and ask you to discuss ways to deal with pine wood nematodes!"

   There is still snow in the sky, but the snowflakes are very small and scattered in the pine forest, making the pine forest even more white and flawless.

  Uncovered withered black pine is even more conspicuous in this environment.

   At this time, a group of people appeared in the pine forest, and some people were cutting down withered pine trees and surrounding pine trees with chainsaws, and several people wearing glasses were studying the pine trees that were sent.

  Wei Chongshan was in this group of people, Wang Yi made a report in the past, Wei Chongshan waved at him:

   "Mr. Wang, come here."

After    Wang Yi passed, a leader took the initiative to reach out to him: "This is Comrade Wang Yi? Thank you so much, Comrade Wang Yi, thank you for making a big contribution to the forestry and environmental work in our city!"

  Cui Qingzi was here at this time, and he introduced him: "This is Su Dai, the leader of our city's forestry bureau."

  Wang Yi warmly stretched out his hands to shake hands with the leaders, and asked, "May I ask that the leaders have already contacted Jinling..."

   "We got in touch with them immediately. In fact, there are people in our bureau who know about pine wood nematode. After the pine wood nematode appeared in Jinling last year, a technician in our bureau specially learned about this pest." Su Dai said.

  Wei Chongshan said: "Now we have encountered a problem. Our country lacks experience in dealing with pine wood nematodes. Mr. Wang, you have some insights in this regard, right?"

  Su Dai said: "Yes, pine wood nematode disease has just developed in my country, and the epidemic has not yet spread across the country. Of course, the epidemic area has seen a jump-like spread, and the base of the epidemic is getting bigger and bigger, which is not a good thing."

   "Our country lacks experience in the prevention and control of pine wood nematode disease, and according to the information we have received from colleagues in Jinling, the prevention and control of this epidemic is a world problem."

   "Especially, pine wood nematode was only detected last year. Our monitoring capability is relatively insufficient, our quarantine supervision force is weak, and our infrastructure is outdated, resulting in ineffective prevention and control."

   Having said this, he sighed: "Fortunately, you knew about pine wood nematode and discovered the trace of this pest in time, otherwise, it would be unimaginable!"

   A technician said solemnly: "That's right. Although our unit has learned about the hazards of pine wood nematode last year, we really never thought that it would appear in our Wengzhou across provinces."

   "It's winter now, and the pine wood nematodes are not active. If the flowers bloom in the next spring after this winter, the pine wood nematodes will enter the active period, and our seviewing forest will be destroyed!"

   This is no exaggeration.

   Because in another time and space, this pine forest was eventually destroyed.

  The attitude given by the leaders and experts made Wang Yi very comfortable, and with Wei Chongshan's face, Wang Yi naturally had to perform well.

   He said: "It was also a coincidence that I read the introduction about this pest in the newspaper. Now we still have time to deal with them. I hope we can face them and have a beautiful encounter!"

  Wei Chongshan nodded: "It is indeed an encounter. Although the enemy is small, it is powerful. We have to do everything possible to deal with it."

   "Old Su, tell me your opinion. Now that Teacher Wang is here, let's discuss it together."

   Cui Qingzi asked, "Mr. Leaders, it's still snowing here, why don't we go to our headquarters?"

  Wei Chongshan waved his hand and said, "We need to go deep into the front to fight a war. If we, as leaders, can't understand the enemy's situation immediately, how can we think about winning the war?"

  Sudai said: "Okay, then I'll talk about some ideas that we have temporarily discussed in our bureau."

   "First of all, we have to carry out prevention and control. One of the experiences given by colleagues in Jinling is about prevention and control."

   "We believe that pine wood nematode disease is preventable for pine trees that have not been infected with pine wood nematode disease; for the entire pine forest, pine wood nematode disease is controllable."

   Wei Chongshan nodded after hearing this, and asked with concern: "But our Guanhai Tingtao Forest has already been flooded with pests. Is it too late to control it now?"

  Su Dai said with a smile: "If it's too late, leader, put it in a troubled forest. What we need to do in the prevention and control work is to control the pine trees that have not been attacked by pests, but have been attacked."

  Wei Chongshan nodded again and said, "Okay, you continue to introduce."

  Sudai went on.

  The follow-up work is primarily to control the Guanhai Tingtao Forest, and prevent the outflow of pests and epidemics.

   And watching the sea and listening to Taolin will also help.

   It is still relatively early to discover the pine wood nematode, and the epidemic can still be managed.

   Therefore, we will conduct a census and daily inspection of the jungle later.

   He said: "We have formulated a three-early strategy, early detection, early warning, and early disposal. Then, we will first conduct a census of all pine trees in the forest area, and the dead pine trees will be erected by horses to dig out the parcels and bring them out."

"Pine trees with reddish-brown or yellowish-brown needles; pine trees with wilted whole or some branches withered or dead; pine trees with egg-laying grooves and intrusion holes of medium insects such as longhorn beetles in the trunk; A pine tree without turpentine—"

   "These will be the diseased trees we will focus on monitoring."

   "These trees need to be drilled to search for traces of pests. Once pests are found, they will also be dug out of the package."

  Wei Chongshan pursed his lips and thought, then said: "Forget it, don't worry about it, as long as it is a tree that is likely to suffer from diseases and insect pests, it will be cut down and moved away."

  Sudai said: "Okay, that's a pity."

  Wei Chongshan patted the pine tree beside him.

   After ten years, the pine tree has grown into a big tree. At this time, it is covered with snow. After being beaten hard by him, the crown of the tree trembled, and the snowflakes fell one after another, as if the snow suddenly increased.

   He said earnestly: "It would be a pity if this pine forest was destroyed by a plague of insects!"

Several forestry experts next to    nodded.

  This forest of watching the sea and listening to Taoism is their brainchild. If it is destroyed by pests, it will be heartbroken.

  Su Dai continued to introduce that in addition to forest control, vector insects should also be controlled:

  During the emergence period of vector insects, they will use highly toxic slow-release pesticides for multiple consecutive applications to control vector insects.

   There are various methods in this regard, such as trapping, vertical luring, perforation and injection, and natural enemy prevention and control. It is necessary to eliminate vector insects first.

   The same principle is also used in the killing of pine wood nematodes.

   But Sudai admitted: "Because the nematodes are tiny and live deep in the trees, it is difficult to kill them with drugs, so we have to consult the experts of the higher-level units and ask them for guidance."

  Wei Chongshan was very satisfied with his arrangement after hearing it.

   After all, this is only a temporary arrangement, and the specific work will be more detailed later.

At the same time, after listening to Su Dai's report, he looked at Wang Yi and said, "Mr. Wang, you are the first person to discover the epidemic, and you should also know something about nematodes, so can you give pointers to our comrades in the Forestry Bureau? How many words?"

  Wang Yi hurriedly said: "Leader Wei, you have shown your love. It is purely coincidental that I found out about the pine wood nematode, and the Soviet Bureau and the experts present here are all experts. My words in front of them are purely a slap in the face."

   "But the leader has ordered my generals, and there is Suju Zhuyu in front of you, so I will continue to say a few words?"

   "What you said may not be correct. If there is any mistake, please ask Su Bureau to correct it, and ask teachers to advise."

   His attitude made everyone very satisfied. Su Dai patted him on the shoulder and said, "The young man is very knowledgeable. He does seem to be a capable intellectual of the new era."

  Wang Yi politely waved his hand, and then cut to the subject: "Leaders and teachers, let me first add some thoughts on the elimination and treatment of epidemic wood."

   "The Soviet Bureau has already said that the diseased, dying, and dead pine trees in the epidemic area will be completely cut down. The Soviet Bureau has fully considered, first seal and then cut down, first wrap the pine trees, then cut them and take them out."

   "But in addition to these pine trees, I think we should pay attention to the traces of vector insects such as longhorn beetles? Winter and spring are the non-emergence periods of vector insects, which is a good period for intensive removal."

   "Of course, the Soviet Bureau mentioned the eradication of vector insects, what I mean is - we should pay attention to the fact that vector insects burrow and lay eggs, and destroy them in the cradle."

  Wei Chongshan laughed when he heard this: "Yes, we must eliminate the pests in the cradle and kill the danger in the cradle."

Wang Yi waited for his voice to fall and said, "Su Bureau proposed to use strong and effective pesticides to kill vector insects, but the pine wood nematodes are too small and like to burrow deep into trees, so using drugs may not be effective, and it will easily cause environmental pollution. ."

   "In this case, can we introduce a large number of natural enemies of long beetles into the pine forest?"

"For example, woodpeckers, such as an insect called Swollen-legged Beetle, actually do not have many long beetles in the pine forest. As long as we introduce their natural enemies and can retain them, it is not difficult to eliminate long beetles. "

   His voice fell, and a young technician said: "Using the relationship of the food chain to control pests, this is a popular pest control model in Europe, called biological control! This comrade is very knowledgeable."
