After Chen Cheng finished speaking, Zeng Lao took the lead in standing up and applauding.

The experts also stood up and applauded enthusiastically.

It can be seen that these things that Chen Cheng talked about are very useful to them.

After bursts of applause, Chen Cheng asked: "Do you have any questions, please put them forward and we will discuss them together." ”

After saying that, the experts who were still talking to each other immediately sat upright, and the venue fell into a silent silence.

This was something Chen Cheng didn't expect, and he thought that everyone would ask a lot of questions that caught him off guard.

Outcome... Unexpectedly cold.

"Did I say it so badly that they didn't understand it?" Chen Cheng couldn't help but doubt the effect of his lecture just now.

He had no choice but to cast a look at Zeng Lao for help.

Zeng Lao turned his head and looked around at the experts behind him.

"You don't have any comments or questions you want to communicate with Chen Cheng?" He asked, confused.

There was silence again.

"Elder Zeng, it's not that we have no problem, but we haven't eaten all the things Chen Cheng said, and we're afraid that the questions raised will make jokes." Someone plucked up the courage to say.

Chen Cheng didn't understand what this sentence meant, but he heard Zeng Lao laugh and said, "I said you, you always have an expert's shelf." ”

With that, he stood up.

"I tell you the truth. As far as I, as well as Academician Zhou Kai, when we discussed rice technology with Chen Cheng, most of the time we asked him questions in the attitude of a student.

Because you're an expert, you're afraid of saying the wrong thing? Haven't you ever learned the phrase 'threesomes must have my teacher'? ”

After Zeng Lao finished speaking, the noisy sound of experts communicating privately sounded in the venue.

Finally, someone raised his hand and asked, "Chen Cheng, I want to ask where you found the plant mineral runge native plant?" ”

"In Yanyuan County, Hanxi Province." Chen Cheng said.

He has published the chemical formula of the mineral operator worldwide, and it will not be a problem to talk about this discovery now.

"May I ask if you have developed other crop varieties for this plant mineral operation in addition to rice and mandarins?"

Chen Cheng shook his head and said: "My energy alone is really limited, if experts are interested in experimenting on other plants, they will give me full support when they need me." ”

"Thank you." The man said with a happy face: "I am an agricultural technology researcher from the Northwest Desert, and we have been engaged in desert watermelon cultivation and technical research. I think that oranges have achieved a high mineral content of sweet and salty through this technology, and watermelon should be able to achieve the same thing. ”

Chen Cheng nodded and said, "Well, it will definitely work." If there's a technical issue that I need to work on, I'm more than happy to do it. ”

At this time, Zeng Lao stood up and said, "You are Brida from the Xinkang Provincial Agricultural Research Institute, right?" How's your desert management there? Has the area under watermelon acreage increased? ”

Brida rubbed her hands at a loss and said, "I'm Brida, I didn't expect Zeng Lao to remember me." Let me report to you that the desert management over there is still going well, but the manpower and material resources consumed are too great, and the results of desert improvement are 1,000 acres per year.

Desert soil needs to be improved for more than five years before it can be used as normal land, so the area of watermelon cultivation has not increased much compared to five years ago. ”

Zeng Lao sighed and said: "Five years ago, you held a seminar on desert management, and I heard your report, and I was very shocked by your proposal to gather the strength of the whole province to control the desert. This is a major event that will benefit the present generation and the future. Of course, before the new agricultural technology, the cost of manpower and material resources must be enormous. ”

Brida nodded and said, "Indeed, after persisting for so many years, the province's finances are also a little tight, so I thought about discussing the improvement technology of watermelons with Mr. Chen Cheng to earn more income for the province." ”

Zeng Lao sat down, thought for a moment, and then asked: "Xiao Chen, can the soybean variety rhizome development technology you just talked about be used in other varieties, or can it be improved and used in their desert?" ”

Chen Cheng said: "Teacher Brida, after the meeting, I will learn the current desert management technology with you in detail, and discuss the follow-up technical direction. ”

Brida nodded happily.

"Expert Chen Cheng, what I want to ask is if you can cooperate with our Northeast Agricultural Technology Research Institute to help us do a technical research on high cold-tolerant wheat?" Another expert stood up and asked.

"What is the progress of your research so far?" Chen Cheng asked.

"In our northeast, the land is vast and sparsely populated, and the land is fertile, but the biggest restriction on agriculture is the ice period of more than four months a year."

Northeast China is one of the main areas of frost damage in northern China, and in addition to the fact that crops cannot be planted in the winter covered by ice and snow, early frost in autumn often affects the immature autumn crops. In order to reduce the damage of early frost in Tohoku, the defense measure is to breed cold-resistant varieties.

In the Tohoku region, even wheat that is more cold-tolerant than rice can only be planted for one season, and spring wheat must be grown.

Although winter wheat is more cold-tolerant, it cannot withstand the severe cold in Northeast China. The winter climate in the Northeast Plain is too cold, and winter wheat cannot be overwintered, and winter wheat cannot be planted.

In China, it is generally bounded by growth, with spring wheat in the north and winter wheat in the south. Moreover, in terms of planting yield, China is dominated by winter wheat.

Winter wheat is grown in warmer areas, usually sown from mid-to-late September to early October, and matures at the end of May of the following year. For example, early winter wheat in Hanzhong Province.

Spring wheat is planted in a very cold place in winter, because it is too cold in winter to be sown, so it is planted after the beginning of spring, called spring wheat, sown in spring and harvested in autumn. The temperature in the spring wheat planting area is generally low and the production season is short, so it is mainly harvested once a year.

Spring wheat is sown in late March and early April and harvested in mid to late July. Spring wheat has a strong drought resistance, short plants and large ears, and a short growth period, which is suitable for spring sowing, but it is not as delicious as winter wheat flour.

"What the Tohoku Institute of Agricultural Technology wants to achieve is wheat that can be grown in winter. In this way, it is possible to achieve two wheat crops a year. The output has doubled, which can be regarded as maximizing the use of the black soil in Northeast China. The expert said.

Zeng Lao added: "In other words, it is not easy to develop a new variety of wheat seedlings that have been buried under the snow for at least three months!" ”

Chen Cheng said: "There is no fear of difficulty, only the technical direction is correct, and continuous research in this direction will always lead to a successful day." ”

Zeng Lao nodded approvingly.

The technologist sat down happily as well.

"What other provinces do you have, and if there are any technical issues that need to be jointly studied by Chen Cheng and you, hurry up and put them forward."

Then the whole venue was a sensation, and the experts rushed to stand up and ask questions.
