For a while, the experts under the podium all stood up one by one, raised and waved their hands, and asked Chen Cheng questions.

Only now have they completely put down their shelves as specialists.

Zeng Lao smiled.

More than half an hour passed, and almost two dozen experts, each of whom put forward the direction they were currently studying and the technical problems they were encountering.

Chen Cheng listened and memorized, and took the time to ask what he felt he didn't understand clearly.

In the end, seeing that it was about to be lunch time, Zeng Lao stood up and interrupted everyone's enthusiasm for questions.

"Experts, let's stop!"

Zeng Lao said, but there was a clear smile on his face.

"You have made a detailed material of the technical difficulties you have encountered, including the current technical progress, technical direction, etc., and sent them to my office when the time comes, and we will forward them to Chen Cheng."

"Good!" The experts in the audience applauded together.

"Elder Zeng, then who comes first and who comes after?" Someone asked in a loud voice.

"What do you mean?" Zeng Lao wondered.

"I'm afraid there are no less than forty or fifty technical problems that need to be solved, and expert Chen Cheng can be busy. Even if he visits one by one, I'm afraid it will take a year. Which one should be solved first? The man explained.

Zeng Lao smiled: "What's the matter? Do you want to get a lottery system for you? ”

There was a burst of laughter from the audience.

"Whose problem is the most urgent, and who can contribute to China's food security as soon as possible after being solved, will solve his problem first.

As for the technique of increasing the spiciness of Chaotian pepper that you have asked about, I think it will be at the bottom. ”

There was another burst of laughter from the audience.

Zeng Lao pressed his hand and said, "Everyone, Xiao Chen is not a robot, I think he is quite tired every day." The development of our agricultural technology in China is not something that he can support alone. What is needed is the joint efforts of everyone.

Before this, our various agricultural research institutes were engaged in their own activities, and there were few exchanges and cooperation, as if they would be stolen by others if they participated in technical exchanges. It's called doing it behind closed doors! ”

He paused and said, "Everyone should know how many years the agricultural technology of the ugly country and the state of Zhizhou is ahead of us. We still have a long way to go to break the technological monopoly and realize China's complete food security and self-sufficiency in grain.

So, my old man is here today to say a word, I hope that all of us will not cover our own things, but be united. Unity is strength! ”

After he finished speaking, Chen Cheng took the lead in applauding, and the other experts in the audience also nodded and applauded.

At this stage, Zeng Lao has gone beyond making a technical content, but is worrying about the future of agricultural technology in China.

Everyone also understood why Elder Zeng would personally call the agricultural technology research institutes in all provinces across the country and invite them to send major technical backbones to attend the meeting.

The level of vision of ordinary researchers is too different from that of Zeng Lao.

"So, I mean, you first have to open your mind and share technology with fellow experts and work together. And Xiao Chen is just acting as a 'firefighter' to help you solve the most difficult technical problems. Zeng Lao said.

Chen Cheng said: "I am just a student, and my ability still has shortcomings, so I can only say that I will study with you." ”

Zeng Lao joked: "Xiao Chen, don't be modest. As far as your technical level is concerned, I think the academicians are qualified. ”

Unexpectedly, the experts in the audience began to discuss.

"These techniques of Xiao Chen's experts are enough to evaluate academicians."

"He's still too young, if you have a team and then produce more results, it should be fine."

"Who said that academicians have to be at what age to be evaluated? I think it's pedantic. ”

"Yes, Chen Cheng's contribution to the development of domestic agriculture is obvious to all."

....

After the luncheon of the meeting, under the organization of Zeng Lao, Chen Cheng met with Brida.

Brida pulled out her computer and played their desert management techniques on the projection.

Desert management refers to the use of technical means to curb the spread of deserts. The main reasons for the expansion of desertification are the irrational activities of human beings, drought and water shortage, scarcity of vegetation, and wind-driven effects.

China is one of the countries with the most serious desertification in the world, with a desertified land area of 2.64 million square kilometers, accounting for 27.5% of the country's land area.

In desertification, especially the desert is the most serious, its area has reached 809,000 square kilometers, and continues to expand and spread, an average of about 610 square kilometers of desert is activated every year, of which 310 square kilometers of land has been reduced to sand.

Desertification has caused an imbalance in the ecosystem and the area of arable land has been shrinking, which has a serious impact on China's industrial and agricultural production and people's livelihood.

"In other words, the area of deserts we manage every year is not as large as the area of deserts that has not increased?" Chen Cheng asked in surprise.

Brida nodded.

"Of course, recently the state has been mobilizing desert management in all directions, and the desert growth rate has been controlled." Bridda Road.

Zeng Lao said: "Therefore, it is necessary to develop rapid and effective desert management technology. For example, the technology of using water to control sand is simply a drop in the bucket, but plant sand fixation and sand control are the direction of the future. ”

"Yes. That's the path we're currently choosing. "There are many drought-tolerant crops, and if the soil can be improved to a level suitable for cultivation, the desert can also produce food." ”

"Desert plant management refers to the sowing of psammophytes in desert areas to halt desert expansion and improve desert land.

Psammophytes have the characteristics of less water transpiration, developed mechanical tissues and conduction tissues, etc., which can resist the attack of strong winds, and transport water and nutrients to urgently needed organs as soon as possible. ”

"What we do is we use a lot of manpower to plant the sand plants, let them fix the sand, and then improve the soil after they fall off the ground and the leaves and branches decompose in the soil."

"The main problem here is that at present, whether it is cultivated in China or introduced abroad, desert plants are growing slowly, and the soil improvement effect cannot be produced in five to ten years."

After Brida finished speaking, a helpless expression appeared on her face.

"What are the psammophytes you're growing so far?" Chen Cheng asked.

"Populus euphratica, sand date, sand willow, Junjun tree, etc."

Zeng Lao said: "Although these plants can grow in the desert, their effect on improving the desert soil is very slow, and the local government can't stand it if they survive like this." ”

"So you're suggesting to use soybean rhizome development technology to help them speed up?" Chen Cheng asked.

Zeng Lao said: "This is just a preliminary idea of mine, just a suggestion. The specific situation needs to be analyzed on a case-by-case basis. ”

Chen Cheng thought for a while and said, "Are there any suitable cash crops that can be planted?" ”
