The Academy of Agricultural Sciences and the outside world seem to be two different worlds.
The Huaguo Academy of Agricultural Sciences is located in Zhongguancun, Haidian District. The outside is full of high-rise buildings. But the building of the Academy of Agricultural Sciences is very short, and there is also a 79-hectare experimental farm inside.
There are 79 hectares in Haidian District. One hectare is equal to 10,000 square meters. The experimental farm is not too luxurious.
But there are very few staff inside. It's just that after Jiang Yan came, there were more staff. Why do the old people here have so many new faces?
After communicating with Jiang Yan last time, he also discovered that the seeds Jiang Yan picked seemed a bit strange, and Dong Wenxu became interested in work.
Before, he worked based on orders and discipline, but now he works out of interest.
Later, the Institute of Agricultural Sciences transferred another hundred people to their team. Dong Wenxu found that all those who had some knowledge of agriculture and seeds were transferred.
Jiang Yan's team already has more members than researchers at many institutes affiliated with the Academy of Agricultural Sciences.
With more people, a lot of work can be delegated, and a lot of work that was originally scheduled for later can be moved forward.
Dong Wenxu was the first to arrive and became the liaison of the team. Of course, he still had to work.
Today's work is aimed at understanding specific modules of transgenic soybean during development, including regulators of hormone signaling pathways and transcription factors.
"You are responsible for analyzing the transcriptome, and then, Zhao, you will make a two-dimensional data set from the material they analyzed."
"Then we will conduct pairwise comparisons and build a dynamically expressed gene network platform to facilitate subsequent soybean seed genetic analysis."
"At the same time, the co-expressed gene modules and hub gene modules of each module have recently been determined."
Dong Wenxu and the researchers said.
Research on soybeans has always been carried out. In 2010, foreign countries completed the sequencing of the entire genome of the willimas82 soybean model.
Foreign seed industry giants are much ahead of China in the field of genetically modified seeds.
As for the team led by Jiang Yan, their idea is to achieve overtaking in corners through special abilities.
They do not need to sequence them one by one, but use genome-scale technologies such as microarrays and cDNA sequencing, which have been used to isolate genes and reveal regulatory networks.
They did not require these genomic approaches to identify the key genetic bottlenecks that manipulate the number and size of soybean seeds.
They only need to find the genetic mutation fragment in the seeds selected by Jiang Yan and find out what good traits this fragment plays.
Then they use technical means to combine all the good traits into one seed, and this seed is the seed they finally cultivate.
It took Monsanto five to ten years and hundreds of researchers to come up with it. Jiang Yan led about a hundred people and conducted seed research on dozens of crops at the same time, and it took half a year to come up with it.
Jiang Yan was deeply moved by Mo Nao's improvement in seed cultivation efficiency.
If this technology had been available back then, he would have developed better hybrid rice long ago.
During this period, Jiang Yan himself was mainly engaged in the improvement of hybrid rice, and had cultivated hybrid rice and sea rice with better quality and more in line with market needs.
In fact, the advantages of hybrid rice have been declining in recent years, from nearly 80% of the planting area back then to 50% in recent years.
Especially in the past two years, the planting area has been declining. In 2019, the planting area was 1.38 million acres, which was 18% lower than that in 2018. In 2020, the planting area was 1.15 million acres, which was another 17% decrease.
Conventional rice has been making progress in recent years, but the advantages of hybrid rice compared with conventionally bred rice are not obvious enough, and hybrid rice is not progressing fast enough.
In terms of economic benefits, conventional species are even slightly better, because conventional species produce less but sell for a higher price.
Therefore, Jiang Yan has re-optimized the most commonly grown hybrid rice on the market in terms of taste, yield, and fertilizer absorption rate.
The cultivated sea rice also fully meets the requirements. In both cases, a large number of genetic mutations are used to select excellent varieties, and then hybridization with excellent traits is carried out to produce the best seeds.
"We can send people to get relevant research materials and seeds, and we can prepare for promotion."
...
At Huaguo Seed Group Co., Ltd., they received seeds sent by the Ministry of Agriculture, which were said to be the latest research results of the Institute of Agricultural Sciences.
"This was recently developed by the Academy of Agricultural Sciences. It is possible to achieve a seawater rice yield of 600 kilograms per mu in saline-alkali soil with a salt content of 3%."
"I hope you will prepare for large-scale promotion after verification!" The person responsible for delivering seeds said that he was from the Ministry of Agriculture, but his actual identity was from the Bureau of Abnormalities.
Chen Jingrui, deputy general manager of the Seed Group, opened his eyes wide: "Three percent? Are you sure you're right? Isn't it three thousandths?"
The other party replied with certainty: "That's right, it's three percent."
"The yield per mu is six hundred kilograms?"
Chen Jingrui is an agriculturist and has worked in the fields many years ago. He also knows about sea rice. After confirming it repeatedly, he picked up the seeds and thought, "Who put the satellite in MD?"
"You're not trying to trick the ministry, are you?"
"If this was so awesome, it should be on the news in the morning."
The best sea rice before China could only maintain high yields per mu in saline-alkali land with a salt content of 6%.
Because the saline-alkali land in China is low, like in the Northeast, the salt content is about 7 parts per thousand. In high places, such as the Guangdong Sea, the salt content is even 16 to 20 parts per thousand.
Therefore, although the sea rice developed previously has been widely reported by the media and is a breakthrough, it is actually still far from being widely promoted in reality.
There is a gap between careful cultivation by researchers in the experimental environment and large-scale sowing in reality, not to mention that the experimental environment only supports a salt content of 6 parts per thousand.
Chen Jingrui was dubious about the seeds sent by the ministry. What did three percent mean? It can be promoted on a large scale in saline-alkali lands across the country, and there is no regional distinction.
Many places abroad will rush to buy the seeds of this kind of sea rice. If the yield is really 600 kilograms per mu, the salt content will be 3%.
The role of sea rice is not only to produce output, but also to improve the soil environment. Many abandoned old industrial areas in Europe and the United States can be alleviated by large-scale planting of this saline-alkali land.
At the same time, many ecologically fragile saline-alkali lands can be improved to grow more economically beneficial crops.
Chen Jingrui sent it to the laboratory of Huaguo Seed Group and asked them to conduct experiments in a simulated saline-alkali land environment to accelerate ripening. He wanted to get the answer as soon as possible.
If it is true, the economic benefits contained therein are huge and can definitely bring Huaguo Seed Company's performance to a higher level this year.
Now after the reform of state-owned enterprises, many things are linked to performance, and central enterprises are no exception.
Everyone has to find work to find profit points. Without profit, there is nothing.
Of course, state-owned enterprises like Huaguo Seed Company, which is positioned as a public welfare company, have lower requirements than commercial state-owned enterprises.
The lower requirements here mean that the state has lower requirements for their profit assessment. For example, the profit requirement for public welfare state-owned enterprises is 100 million or even no profit, and the profit requirement for commercial state-owned enterprises is 1 billion.
