Chapter 216: Brown Root Disease
Hearing Wang Jianhua's words, Ye Ning couldn't help but be a little speechless.
Tell yourself to save this banyan tree quickly, as if you can cure it.
But in fact, Ye Ning was not sure, he had never tried to treat plants with Yuan Qi, and he didn't know what the effect was.
Ye Ning said: "I haven't seen the illness of this banyan tree, and I'm not sure if it can be cured." ”
Wang Jianhua said: "Then take a look, I confessed to Liu Jing under this tree at the beginning, and I really don't want it to die like this." ”
Liu Jing, Guo Zhi, and Su Yu all looked at Ye Ning, their eyes were full of expectation, although Ye Ning was the same age as them and had been classmates, but they knew that Ye Ning's attainments in medical skills were far from being comparable to them, and even reached the point where even Professor Xue was full of praise.
Su Yu looked a little more mature, a little less youthful and a little more intellectually beautiful, and he was no longer as embarrassed as before in the face of Ye Ning, but showed a generous smile from Nuo Nuo.
Ye Ning smiled: "In this case, this banyan tree can be regarded as half of your matchmaker." ”
Wang Jianhua said: "It can indeed be said that it is half of our matchmaker, so please leave it to you." ”
Ye Ning nodded and said, "I'll do my best." ”
At this time, Zhou Min came over and handed a document to Ye Ning: "Senior Brother Ye Ning, this is my inspection data on the banyan tree, including the root test results, you can take it and take a look, it can help you save some time." ”
Ye Ning took the information and said, "Thank you, senior sister." ”
Zhou Min smiled charmingly: "Be polite to me." ”
Ye Ning skimmed through Zhou Min's information, and the conclusion she gave was brown root disease.
In fact, when the principal came to the office to talk to Ma Rongbin and Tang Shuang. The symptoms of the banyan tree have been explained. And said that many doctors diagnosed brown root disease (due to infection with brown root bacteria. Diseased trees near the main stem and roots of the ground often have yellow to dark brown mycelial surfaces surrounding their surfaces, and the mycelial surfaces of the roots are often combined with sediment but not obvious), brown root pathogens can directly damage the transport tissues of the bark, resulting in the obstruction of the transport of water and nutrients, causing the yellowing and withering of the whole plant in the aerial part of the plant at the beginning, and finally die.
The banyan tree is symptomatic, almost undoubtedly predominantly brown root disease, and the problem is that the infection is severe and difficult to treat.
The control methods of brown root fungus so far. The results of the determination of pathogenic bacteria in the laboratory and the preliminary test on woodland showed that Sundefen, Tritaifene, Silide, Copper Sulfate, Fenin, Copper Fenin, Copper, Poker, Propronin, Bordeaux Liquid 4-4 and Urea have some degree of inhibition and therapeutic effect on the disease, but they are still not suitable as recommended prevention and control agents because they have not been fully evaluated by the test results and registered in the legal administrative procedures. At the same time, the fungus is mainly harmful to the roots, and the application of the agent is not easy to achieve the expected therapeutic effect, so the effect of the application of the agent is often affected by the tree species and the environment.
In fact. The prevention and control of brown root disease should be based on prevention. Because the pathogen is harmed by the plant, there are no symptoms of disease in the early shoots, and once the shoots appear yellowing and withering, more than 80% of the roots have been damaged, in this case, if you want to treat it, it is too late. The main source of infection of this pathogen is the diseased root, and its transmission route is mainly transmitted by the contact between the diseased root and the healthy root. Therefore, under the consideration of prevention, as long as the contact between diseased roots and healthy roots can be prevented, and the infected residual roots in the soil can be killed or removed, the control effect can be achieved.
Now, the leaves of this banyan tree have yellowed and withered, so it can be said that it is too late, not to mention that this banyan tree is too huge, and the roots are deep, wide and dense, how easy is it to operate?
Although the soil around the trunk of the banyan tree has been turned out, revealing a large area of roots, and a lot of rotten roots have been dug out, the effect is not obvious, the banyan tree is still withering day by day, and there must be many brown root bacteria hidden in the deep roots, which are difficult to remove at all.
It can be said that this old banyan tree is now equivalent to the terminal stage of human cancer, and it is difficult to treat the cause of the disease.
Ye Ning walked under the trunk of the tree, stretched out his hand and put it on a tree root, and then injected vitality, he soon found that the vitality is also effective for the banyan tree, but unfortunately the effect is smaller than that of animals, injecting ten points of vitality to restore a small section of the root to health, and this banyan tree is too huge, if you really rely on this method to treat, I don't know how much vitality will be consumed, and it may even cost hundreds of thousands of points.
Of course, this method is not advisable, not to mention that Ye Ning does not have so much energy, even if he has, he is reluctant to consume it like this for a banyan tree, it is not worth it at all.
Ye Ning frowned deeply, he had encountered a big problem now, and it seemed that he couldn't do anything about it.
……
Not far away, Qian Rui glanced at Ye Ning and snorted coldly: "Pretending, many experts are powerless, he really thinks he can cure it?" ”
A tall and narrow-faced young man next to him also glanced at Ye Ning and said with a smile: "Who is that kid, he looks amazing, it seems that your Zhou Min also looks at him differently." ”
The corners of Qian Rui's eyes twitched: "He is Ye Ning, who luckily cured the old man of the Lu family, Zhou Min is so blind when he sees him, by the way, don't say I didn't remind you, he pursued Su Yu, although he was rejected by Su Yu, but now it seems to be quite close." ”
The long-faced young man pursed his lips: "It turned out to be just an eliminator who was rejected by Su Yu, it seems that there is nothing to care about." ”
Qian Rui didn't say anything more, but he scolded secretly in his heart, you are not much better.
This long-faced young man is called Fan Zhaoran, vice president of the student union, his family is wealthy, some time ago he heard that Su Yu's family has become poor, so he plans to help Su Yu, although it is said that he gave Su Yu money for free, but it has the deep meaning of buying Su Yu with money, but unfortunately Su Yu did not take his money, not only worked part-time in the library, but also worked part-time in a clothing store at the school gate after school, and now the family situation is finally starting to improve. To put it bluntly, Fan Zhaoran is just an eliminator who was rejected by Su Yu, and the reason why he has such a sense of superiority is probably because he thinks that Su Yu will one day not be able to stand the hardships, and he will definitely throw himself into his arms when the time comes.
Fan Zhaoran said: "It seems that this Ye Ning is our common enemy, we should give him some color." ”
Qian Rui said: "How to give him color?" ”
Fan Zhaoran smiled: "Take your time, cure this banyan tree first, and steal the limelight." ”
Qian Ruihu said suspiciously: "The expert of the Plant Protection Association you are talking about, is there really a way?" You know, Professor Xue also saw this tree yesterday, and he hasn't thought of a solution yet. ”
Fan Zhaoran said confidently: "The expert I am talking about has decades of experience in treating plants, and has prevented many forest diseases, if he can't estimate that no one has a way, although Professor Xue is skilled in medicine, after all, he is treating people, and he has no experience in treating plants." ”
Qian Rui nodded and said, "Then what are you waiting for, please invite him to come." ”
Fan Zhaoran said: "Don't worry, I have to discuss with him first, and after he finds out the treatment, tell me all the specific operations, and then let me treat it, and give me all the credit, you can be my assistant and follow the limelight." ”
Qian Rui scolded secretly in his heart, what limelight can he be as an assistant? Can't it be said to be cooperative treatment?
However, Qian Rui knew that Fan Zhaoran was very stingy and didn't dare to ask too much, and acting as an assistant was also a credit, which was better than not being touched. (To be continued......)
