China News Service, Changsha, October 19 (Reporter Tang Xiaoqing) At the first conference sub-forum of the Boao Forum for Asia Economic Development and Security Forum held in Changsha on the 19th, Yuan Longping’s disciple and researcher at the National Hybrid Rice Engineering Technology Research Center Zhao Bingran said that this year’s salt tolerance The demonstration of alkali hybrid rice has made phased progress.

  In this forum titled "Food for the People: Internal and External Improvement of Food Security", Zhao Bingran provided a set of latest data when sharing his views: In 2021, Xing'an League of Inner Mongolia, Kashgar, Xinjiang, Hohhot, Inner Mongolia, and Xinjiang Yue The yield per mu of saline-alkali-tolerant rice in Puhu, Midong, Xinjiang, Rudong, Jiangsu, and Jiangmen, Guangdong reached 537.5 kg, 575.3 kg, 806.66 kg, 595.2 kg, 659.3 kg, 732 kg, and 501.2 kg, respectively.

  It is one of the dreams of Academician Yuan Longping to plant rice on more saline-alkali land and achieve high yield and high efficiency.

This technology can not only improve the ecological environment of saline-alkali land, but also double the income of growers.

There are 400 million to 600 million mu of saline-alkali land in Xinjiang, and a "Xinjiang oasis" is to be built here. If 200 million to 300 million acres of saline-alkali land can be used to grow rice, Xinjiang will become the second Chinese granary after the Northeast.

  In 2018, Yuan Longping Rice Academician Expert Workstation was established in Xing'an League, and 960 acres of saline-alkali-tolerant rice base was built.

Focusing on the work goal of "striving to achieve an increase of 100 kilograms per mu of rice in Xing'an League within 3 years", the workstation actively introduced and promoted the latest salt-tolerant hybrid rice varieties and advanced technologies.

In 2019 and 2020, the average yield per mu of the base will be 508.8 kg and 533.95 kg respectively.

  At present, the average mu of China's salt-tolerant rice trials and demonstrations has reached more than 500 kilograms, and the highest yield per mu is over 800 kilograms. The first batch of 4 salt-tolerant indica rice varieties has passed the national examination and approval.

In March this year, the Ministry of Science and Technology of China approved the establishment of a national salt-tolerant rice technology innovation center.

This is one of the first three national technological innovation centers to be constructed in China's agricultural sector. It carries important tasks such as national salt-tolerant rice research and development, marginal land use, and food security.

  "The functional positioning of the center includes the research and development of major key technologies, the industrialization of the results of industry-university-research collaboration, and business incubation and technological innovation services. It will also plan to establish two salt-tolerant countries in Asia (Cambodia) and Africa (Madagascar) along the'Belt and Road'. Soda Rice Joint Laboratory." Zhao Bingran said that at present, the National Saline Alkali Tolerant Rice Technology Innovation Center has established regional centers in South China, East China, Northeast China, and Northwest China, in Xing'an League of Inner Mongolia, Jiangsu, Hainan Wenchang, Jilin Da'an, Guangxi Beihai and other places. Established a research base for saline-alkali-tolerant rice.

  Zhao Bingran, 56, has been escorting food security for more than 30 years. He has led a scientific research team to pioneer hybrid rice "parental decadmium technology" and directional improvement technology by physical and chemical mutagenesis, breaking through the industry where conventional varieties are grown in heavy cadmium-contaminated fields and rice cadmium exceeds the standard. Development bottleneck.

  "Teacher Yuan has a dream throughout his life, always thinking about super-high yield as the most critical measure and goal of ensuring food security, filling the rice bowls of the people of the country, and benefiting the people of the world. We will uphold the legacy of Teacher Yuan and strive for 8 to 10 years. During the year, the goal of developing 100 million mu of saline-alkali-tolerant rice, with a yield of more than 300 kilograms per mu, increasing annual grain by 30 billion kilograms, and feeding an additional 100 million people will make new contributions to food security in China and the world,” said Zhao Bingran.
