Yuan Longping: Expand the area of "red line" farming to ensure food security

1.5 billion mu of saline land, which is also an extremely important reserve arable land resources for the future of our country. If we urgently carry out research on the cultivation and core technology of salt-alkali-resistant rice varieties and transform 100 million mu of them into rice paddies, estimated at 300 kg per acre, it is expected to increase the annual grain production that can feed more than 80 million people. This is also a work in the contemporary, in the autumn of major innovation projects. "On April 16th, Yuan Longping, a professor at the Chinese Academy of Engineering who is also busy at the
breeding base in Sanya, Hainan Province, told Science and Technology Daily.
the past few days, affected by the outbreak of neo-crown pneumonia, many countries and regions have launched policies to restrict their own food exports in order to prevent local food shortages. The move has also triggered a wave of "reflection" on food security as countries assess the possibility of a "food shortage".
as far as China is concerned, it is not realistic to "expand" the grain arable land area by the "red line" of cultivated land. Therefore, to ensure food security, the main focus is on science and technology to increase the yield of arable land, and mining "red line" outside the possible "no middle-income" area of grain cultivation. Yuan Longping's
the development of salt-resistant rice is expected to increase the area of "red line" cultivation.
around Yuan Longping
this goal, in recent years, the national researchers unremitting efforts, has been salt-resistant rice varieties in the cultivation and cultivation of the "first experience." On the 14th, during the "National Salt-Lyne Rice Innovation Center Test Site Observation and Construction Promotion Conference" in Sanya, Hainan, Yuan Longping
once again made a voice to the outside world: "Through the use of hybrid advantages, the combination of third-generation hybrid rice technology, I am confident of achieving a major breakthrough in new varieties of salt-alkali-resistant rice!" He firmly believes that "hybrid advantage utilization and salt-resistant gene" is the key to achieve the goal of salt-resistant rice breeding.
can we consolidate the "chassis" of this goal more firmly? Hunan, the source of China's super hybrid rice ultra-high yield technology, intends to build a national scientific and technological coordination platform around the core technological innovation of salt-resistant rice, to help break through the "hidden grain in the ground" space, expand the "hidden grain in technology" reserves, to ensure national food security and ecological security. According to the preliminary idea, the platform is proposed to be led by Hunan Hybrid Rice Research Center (National Hybrid Rice Engineering and Technology Research Center), jointly with Hainan University, Sanya City Nanshuang Science and Technology Research Institute, Hunan Agricultural University, Qingdao Hai Rice Research and Development Center Co., Ltd. and other relevant research units distributed in many provinces.
"For China's salt-alkali land distribution, diverse types, research advantage units, platforms and personnel scattered, difficult to concentrate characteristics, collaborative platform to implement the 'headquarters, research centers, regional sub-centers and test stations / base' model construction, the organization of the country's largest range of advantages of forces to work together, reserve the world's leading salt-alkali land using key core technologies, cultivate new growth points in food production, build a world-class salt-alkali rice research and development technology innovation platform, training the industry chain of high-end innovative talent. Tong Xudong, director of the Hunan Provincial Science and Technology Department, said of the concept of a collaborative platform.
And according to hunan hybrid rice center news, the technical route is intended to use hybrid advantage technology to cultivate high-yield, high-quality, widely adaptable salt-alkali rice major new varieties, build different saline-alkali-resistant ecological areas of salt-alkali-resistant rice production and efficient application model and large-scale demonstration.
year, we in Panjin City, Liaoning Province, the new town to carry out salt-resistant new varieties of test species, demonstration area of about 30 acres. Peng Yulin, an associate researcher at the Hunan Hybrid Rice Research Center, who is "squatting" in Panjin, said.
Zhang Yu candle, deputy director of Hunan Hybrid Rice Research Center, which is still breeding base in Sanya South, Hainan, revealed that this year, under Yuan Longping
's personal arrangement, they have deployed new salt-resistant varieties demonstration in 10 provinces and regions of Inner Mongolia, such as Xing UNITA, Heilongjiang Zhaoyuan, Jilin Da'an, Liaoning Panjin, and some of the demonstration bases have now been completed.
