"Brother Chen Kang, come and get pesticides, be sure to spray pesticides on the field today!"

Village Chief Chen Shou shouted from a distance.

"What pesticides to spray?" Chen Kang asked.

"Technician Zhang brought it back, hurry up, don't rub it off!"

Chen Cheng came out of the field and followed Chen Kang to the road to meet the large army of villagers.

They all carried sprayers on their backs and prepared to spray in the fields under the leadership of the village and Technician Zhang.

The group stopped, waited for the village chief to take out a few bags of pesticide liquid from the basket, and handed them to Chen Kang.

Chen Cheng hurriedly took it and looked through it in his hand.

Technician Zhang explained: "This is the pesticide formula that our technicians from all over the county met together to study and decide. 75% chlorothalonil plus 10% difenoconazole and 15% mancozeb 7. This recipe is sure to solve the brown streak disease of lotus root! ”

Chen Shou, the village head, complimented on the side: "Definitely, after all, there are more than 30 technicians in our county, all of whom are highly educated graduate students. ”

After Chen Cheng read the pesticide once, he handed it back to Technician Zhang.

"These pesticides won't do much."

Technician Zhang was stunned for a moment, and his face, which was still smiling, suddenly became gloomy.

Chen Shou saw that his face changed suddenly, and hurriedly said: "This is the son of Chen Kang's brother's family, Chen Cheng, is a student of our Hanxi Agricultural University, eh, he is a senior this year." ”

"Oh!"

Technician Zhang slightly restrained his face, stretched out his hand and said to Chen Cheng: "My name is Zhang Lin, a graduate student graduated from Handong Provincial Agricultural Technology Research Institute, majoring in aquatic crop cultivation. ”

Chen Cheng hurriedly shook hands with him and explained: "Technician Zhang, now the lotus root brown streak disease in our village has reached a serious stage, I see that your pesticide formula is only effective for the brown streak disease in the early stage of the disease, and I am afraid that it will not have any effect after spraying." ”

Zhang Lin asked, "What major are you studying?" ”

"Agricultural technology, majoring in rice cultivation." Chen Cheng said generously.

"Oh, then you may not know much about the cultivation and planting of aquatic crops like lotus root, this brown streak disease is a fungal disease unique to lotus root, and the effect will be very good if you treat it with this sterilizing pesticide."

Chen Cheng said: "As far as I know, the pesticide of the formula you just made only had a good effect in the early stage of brown streak, but now it is a serious stage, and the lotus leaves are about to die. ”

Zhang Lin said with a smile: "We have increased the concentration this time, and it will have a good effect." ”

"High concentrations of pesticides may exacerbate the ablation of lotus leaf page cells, I checked the weather forecast, and there has been no rain in recent days." Chen Cheng said bluntly.

"Do you spray or not?" Zhang Lin said impatiently.

As an agricultural technician stationed in the village, he has made a lot of contributions to the cultivation of lotus roots in Wanfu Village in recent years, and of course, the villagers are also obedient to his decision-making, and no one has ever dared to oppose it.

After all, his education is here, and he is a technician appointed by the county, and his authority in the management of lotus root planting is more than that of the village head.

Chen Cheng was originally discussing the problem with him calmly, but he didn't expect Zhang Lin to suddenly get angry. It embarrassed him a little.

He also knew that Zhang Lin had made a lot of contributions to their village.

So he discussed: "Technician Zhang, I'm not refuting you, but from the current practical considerations, this spraying method may not be very suitable." ”

"What do you think should be done?" Zhang Lin asked rhetorically.

Chen Cheng said: "It is right to eliminate the germ of brown streak disease first, but it is necessary to change the means. The diseased lotus leaves are first removed, and then the bacteria are sanitized in the field water, and after killing, the water is drained and the water is re-stored. Ensure that the germs are completely destroyed. ”

Zhang Lin smiled and said, "College students are just talking on paper, do you know why we don't dare to remove the diseased lotus leaves now?" ”

Chen Cheng shook his head.

Zhang Lin continued: "It's not that we farmers don't have so much time to remove diseased leaves. If it's really for the sake of yield, we have to remove the diseased leaves without eating or drinking. But now I can't pick it up!

Because after picking, the yield of lotus root will be reduced! ”

Chen Cheng understood what he meant.

They want to save the lotus leaves as much as possible, even if they are almost killed by brown streaks, but at least some lotus leaves still have some photosynthetic functions, and can continue to provide some nutrients for the lotus roots in the mud.

One word, drag.

Rely on the tenacious vitality of the lotus root to save this year's production.

This is indeed a solution, but in Chen Cheng's opinion, it is indeed a bit self-deceptive.

Zhang Lin said: "We have estimated that if the diseased leaves are removed, the yield of lotus roots this year will be reduced by at least 50%, but even if these lotus leaves persist for another month, the yield reduction rate should be controlled at more than 30%. ”

"Haven't you considered that the lotus leaf itself consumes energy? It also consumes energy to fight germs, and can it preserve the nutrients in the lotus root, will it really increase? Chen Cheng asked directly.

He quickly used the system in his brain to calculate that the income generated by Zhang Lin's "procrastination" would be beyond his means.

"I won't talk about the feasibility of sterilization in the field water, just say that removing the diseased leaves now will definitely lead to a reduction in yield, and I'm afraid that the villagers of Wanfu Village will not agree to this matter." Zhang Lin said loudly.

Hearing him say this, the neighbors in the village all said: "Yes, how much can be saved, and if the output is reduced by 50%, each household will have to lose more than 10,000 yuan." ”

"Yes, Brother Chen Kang, you can also fight pesticides together."

"Our fields are all sprayed with pesticides, and if your family doesn't fight them, then they still have to infect each other!"

Seeing that the emotions of the neighbors were brought up, Chen Cheng hurriedly said: "Uncles and uncles, it's not that our family doesn't use pesticides, it's that we want to strive for this year's lotus root production not to decrease!" ”

Since everyone is afraid of reducing production, then use production to convince them.

"No reduction in production? How can it be! ”

"Chen Cheng, you kid was quite honest when he was a child, why did he go out to college for a few years, and now he has become bragging?"

"That's it, Technician Zhang said that it would be good to be able to reduce production by 30%, he is an undergraduate, what do you know?"

"You can't say that, didn't Chen Cheng go back to TV last time? You all said he was promising. "There are still people who help Chen Cheng speak.

Zhang Lin said: "Chen Cheng, I know that you are very strong in rice technology, but you have a specialization in the art industry. Playing pesticides is the only way at present, this is the county's decision, and it must be fought! ”

Chen Cheng was about to continue to explain, but was suddenly stopped by Chen Kang.

He didn't understand why his son was also for their good, why they couldn't listen, and he felt a little angry in his heart for a while.

Chen Kang said loudly: "I want to beat you, our fields do not use pesticides." ”

Chen Shou, the village head, wrinkled his eyebrows and said: "That's not good, we are all from the same village, and all actions must be commanded." Besides, how can you guarantee that you will not get infectious bacteria into our fields? ”

Chen Kang said angrily: "I said that if I don't fight, I won't fight, see what you can do?" ”

Chen Cheng hurriedly pulled Chen Kang's sleeve, turned to the villagers and said, "Uncles and uncles, I really have a way to help you solve this problem." Trust me. ”

Chen Shoudao, the village head, said: "What can you do with a small child, if we reduce production by more than half at that time, what do you say?" ”

Chen Cheng was speechless for a while.

"What do you say? Isn't it 10,000 yuan per household? It's a big deal, I'll compensate you! ”

Chen Kang said loudly.
