New Era of Endering New Journal ｜ Zhang Qiqi team's Jianjiang Super "Dae" road

G3 Green Super Rice Test Field

"Don't look at the difference between G3 and conventional rice now. Its advantage is that in the later stage, the ability to divide the ability, disease resistance, anti -falling resistance, and ears will slowly appear ..."

On the 14th, at the experimental field of the Agricultural Technology Promotion Center of the Seven Star Branch of Peking University of Agricultural Agriculture, the seedlings of the "Green Super Rice" academician workstation of Huazhong Agricultural University, led by Zhang Qi, a academician of the Chinese Academy of Sciences Zhang Qi, have grown to Seven leaves, lush and lush, very happy.

Li Xiaohui, director of the promotion center, pointed to the seedlings and said, "The reason why it is called 'green super rice', 'green' is reflected in saving pesticides and fertilizers, 'super' is greatly increased in the perurone. Thousands of acres of water fields can increase production of 1 billion kg of food. "

Super cooperation

"Rice Base"+"Rice Expert"

The Sanjiang River is located in the hinterland of the Sanjiang Plain. The land is concentrated. The three rivers are surrounded by, the terrain is flat, and the soil is fertile. It is famous for its rich green and high -quality rice. In order to better carry the heavy responsibility of the "cockpit" of food safety, the Qixing Agricultural Technology Promotion Center has continuously strengthened cooperation with colleges and scientific research institutes to insert the wings of technology for agriculture.

Academician Zhang Qi, who has long been engaged in the research of rice functional genome and genetic improvement, is a professor at the School of Life Science and Technology of Huazhong Agricultural University. He and the team have built a large -scale research technology and resource platform for large -scale rice functional genome. They identified a group of rice functional genes with important application prospects. The biological foundation used by the advantages of rice hybrids, the genetic foundation of the hybrid advantage, the males are not male Research fields such as educating and sub -breeding have made a series of progress, and the technical system for genome breeding has also been established. He proposed the concept of "green super rice" with less pesticides, less fertilizer, water saving and drought, and high -quality and high -yield. Rice varieties and production.

In 2019, in order to ensure the safety of food and cultivate new green rice varieties and new products, the "Green Super Rice" academician workstation headed by Huazhong Agricultural University led by Zhang Qi settled in the Seven Star Agricultural Technology Promotion Center, opening a super "rice" of a strong union. road.

In 2020, the Seven Star Branch signed a cooperation agreement with the Academician Workstation of the "Green Super Rice" "Green Super Rice" of Huazhong and China Central Agriculture. Update the pace of replacement and broaden farmers' choice of high -quality high -yield rice varieties.

In 2021, the workstation took "Green Super Rice R & D" as the topic, and made full use of the advantages of large seven -star water fields, strong infrastructure, and high management standards. Integrate innovation development.

Super green

Reduce 30%nitrogen fertilizer without reduction of disease resistance and disease resistance

"At that time, the other rice leaves were red -brown plaques, which were very obvious. The leaves of the G3 were very intact. It can be clearly seen that the high antibacteriality of this product ..." Zhang Jincheng, a technician of Qixing Agricultural Technology Promotion Center, recalled the 2020s The bacterial brown spot disease was very emotional about the disease resistance of G3. "At that time, it was continuous rainy days and the wind was also very large. The leaf tape rubbed each other. . "Zhang Jincheng said that at the time, many conventional planting rice infected with bacterial brown spot disease. From the perspective of the test field, the G3 had obvious high antibacteriality.

The excellent "Green Super Rice" excellence in addition to the super strong resistance to the virus, and performs well on the fat reduction medicine. It is a common impression that many people can produce more grain production. However, "Green Super Rice" rely on excellent genetic genes to achieve the effect of 30%nitrogen fertilizer without production.

"Our routine rice is about 31 kg per mu. If the G3 is G3, the amount of fertilization of acres is 27-28 kg." Li Xiaohui told reporters that after three years of experiments, the use of Nitrogen fertilizer in G3 products has decreased by 30% by 30%. The output per mu still continues to exceed 1400 catties, an increase of about 100 pounds compared with the conventional rice per mu.

Super secret

Leave the optimal gene for rice "nucleic acid detection"

What is the secret of "green super rice" such a "can be played" secret?

"We keep the genetic material of disease resistance, fertilizer, and high -yielding of the rice, and continue to optimize and upgrade." Li Xu, an associate researcher at the School of Life Science and Technology, Huazhong Agricultural University, has been working in construction for a long time since 2019 Sanjiang.

"Rice is also a organism, which can perform 'nucleic acid detection' like humans. One of the nucleic acids, that is, DNA genetic material, can determine the tall and thinness of the plants 'offspring', whether it is disease -resistant, whether it is high. There are 30,000 to 40,000 genes. At present, rice scientists have analyzed the functions of nearly 4,000 genes. On this basis, the academician team has established the rice genome breeding technology system. The rest of the elimination and gradually stabilize the traits so that you can cultivate excellent rice. "

Li Xu told reporters that China's rice scientific research has gone at the forefront of the world. The whole genome sequence database of the remaining germ resources. Through years of research, Academician Zhang Qi slowly increased the many high -quality attributes of the southern rice rice to the northern rice rice. At present, the project team conducted an "plant factory" experiment for the green super rice. Four years of cooked, accelerate selection of varieties, upgrade iterative, and continuously improve seed quality. Cracking the technology and resource bottlenecks of rice breeding in high cold areas.

In addition, the team of Academician Zhang Qi is currently developing the "black rice staple food" to increase the nutritional value of rice and reduce the loss of fine rice processing on grain production. This project can indirectly increase the edible output by 30%. Let the people not only eat full, but also eat well.

According to reports, the "Green Super Rice" G3 products and red rice products have begun to be in the specifications, and they need to be officially entered the promotion phase through 3 to 4 years of multi -point evaluation by the competent agricultural authority. At that time, 10 million acres of green belt in the province's third accumulated temperate zone can increase the income of 1 billion pounds of rice.
