How to carry out the variety cultivation and core technology research of salt-tolerant rice？

Yuan Longping, academician of the Chinese Academy of Engineering, put forward the latest guidance: “Continuously discover the salt-alkali tolerance gene of rice and transfer it to indica-japonica high-yielding hybrid rice, especially the third generation hybrid rice.” April 14 in Haiya, Hainan At the State Bay Science and Technology City, the National Saline-Alkali Tolerant Rice Technology Innovation Center test site observation and construction promotion meeting, the reporter of Science and Technology Daily obtained the above information.

“Salt-alkali-tolerant rice research is being done in many countries, including India, Japan, South Korea and other countries, and even some countries have been studying for decades, but the progress has not been great. Why do we only have a few years of research Breakthrough? ”Yuan Longping said,“ Because we have combined the salt-tolerance gene of rice with the utilization of rice heterosis. ”

Academician Yuan Longping ’s goal of developing saline-alkali-tolerant rice is that within 10 years, select saline-alkali-tolerant rice varieties with a salt tolerance of three to six thousandths and an alkali tolerance of pH 9 or higher, and the annual promotion area Up to 100 million mu, with an average yield of 300 kg per mu, so that 30 billion kg of grain can be increased every year.

“What is the concept of 30 billion kilograms of grain? This is equivalent to the current annual grain output of Hunan, which can feed nearly 80 million people.” At this point, 89-year-old academician Yuan Longping was very excited.

China has 1.5 billion mu of barren saline land, which is an important reserve arable land resource of the country. The rice researcher in China, pioneered by Academician Yuan Longping, is committed to breaking through the space of “grain storage in the ground”, expanding the reserve of “grain storage in technology” to ensure national food security and ecological security, and promoting the implementation of the “Belt and Road” initiative.

Based on this, academician Yuan Longping proposed that the national saline-alkali-tolerant rice technology center aiming to seize the leading position of international saline-alkali land utilization technology and cultivate new growth points in grain production is intensifying preparations.

It is understood that the center is led by the Hunan Hybrid Rice Research Center (National Hybrid Rice Engineering Technology Research Center), in conjunction with Hainan University, Sanya Nanfan Science and Technology Research Institute, Qingdao Hai Rice Research and Development Center Co., Ltd., Hunan Academy of Agricultural Sciences, Guangdong Jointly built by Ocean University, Hunan Agricultural University, Jiangsu Academy of Agricultural Sciences, Heilongjiang Academy of Agricultural Sciences and other units.

In view of the wide distribution and variety of saline-alkali land in China, the research superior units, platforms and talent teams are scattered and difficult to concentrate. The center will implement the “headquarters, research center, regional sub-center and test station / base” model to build The scope realizes the relatively concentrated strength of the nation’s superiority, connects with the support of local governments, and fully mobilizes manpower, material resources, and platforms to co-operate in the construction of this major project.
