Yuan Longping: Expanding the cultivation area outside the "red line" to ensure food security

"Our country has 1.

In the past few days, affected by the new crown pneumonia epidemic, many countries and regions have launched policies to restrict their own food exports in order to prevent local food supply shortages

As far as China is concerned, affected by the "red line" of cultivated land area, it is not realistic to greatly "expand" the area of ​​grain cultivated land

Focusing on the goal of Academician Yuan Longping, in recent years, researchers across the country have made unremitting efforts to tackle key problems and have gained "first experience" in the cultivation and planting of salt-tolerant rice varieties

How to consolidate the "chassis" for the realization of this goal? Hunan, the birthplace of China's super-hybrid rice super-yield technology, plans to build a national scientific and technological collaboration platform around the core technological innovation of saline-alkali-tolerant rice to help break through the space of "grain storage in the land", expand the reserves of "grain storage in technology", and ensure the national grain Safety and ecological safety

"In view of the wide distribution and diverse types of saline-alkali land in China, and the scattered and difficult concentration of research superior units, platforms and talent teams, the collaborative platform plans to implement the construction of a 'headquarters, research centers, regional sub-centers and experimental stations/bases', and organizes the largest nationwide Collaborate to tackle key problems with a wide range of advantageous forces, reserve world-leading key core technologies for the utilization of saline-alkali land, cultivate new growth points for grain production, build a world-class R&D technology innovation platform for saline-alkali-tolerant rice, cultivate a national high-end innovative talent team for the entire industry chain, and build saline-alkali-tolerant rice.

According to the Hunan Hybrid Rice Center, on the technical route, it is planned to use heterosis technology to cultivate major new varieties of saline-alkali-tolerant rice with high yield, high quality and wide adaptability, and build high-yield and high-efficiency application models of saline-alkali-tolerant rice in different saline-alkali land ecological regions and demonstrate it in a large area.

"This year, we launched a trial planting of new salt-and-alkali-tolerant varieties in Xinxing Town, Panjin City, Liaoning Province, with a demonstration area of ​​about 30 mu

Zhang Yuzhu, deputy director of the Hunan Hybrid Rice Research Center, who is still in the South Breeding and Breeding Base in Sanya, Hainan, revealed that this year, under the personal arrangement of Academician Yuan Longping, they have already participated in 10 national projects including Xing'an League in Inner Mongolia, Zhaoyuan in Heilongjiang, Da'an in Jilin, Panjin in Liaoning, etc.
