China News Service, Xing'an League, September 25 (Reporter Zhang Wei) "537.5 kg! The yield of saline-alkali-tolerant rice per mu in the Xing'an League Yuan Longping Rice Academician Expert Workstation has exceeded the 500 kg mark for three consecutive years." On the 25th, Zhan Zengbai In the vast saline-alkali land and now the golden rice field, Ma Jun, a professor at the Rice Research Institute of Sichuan Agricultural University, excitedly announced to the outside world the results of the 2021 salt-tolerant rice production test in Xing'an League, Inner Mongolia Autonomous Region.

　　On the same day, 2021 Xing'an League Yuan Longping Rice Academician Expert Workstation Quality Rice Production Test and "Saline Alkali Land Efficient Utilization Model" on-site observation meeting was held at the Saline Alkali Tolerant Rice Planting Base (hereinafter referred to as the base) in Keyouzhong Banner, Xing'an League, Inner Mongolia Autonomous Region, from Sichuan Agriculture Five experts from the University Rice Research Center, Hunan Provincial Department of Agriculture and Rural Affairs, Xing’an League Agricultural and Animal Husbandry Technology Extension Center and other scientific research institutions tested the yields of three rice fields with a random sampling area of ​​0.98 acres, 0.82 acres, and 0.86 acres at the base.

　　Finally, remove impurities and moisture. On the saline-alkali land with a pH value of 8.8-9.6 and a salinity content of 5‰-6‰, the actual yields of the three measured fields are 566.40 kg, 513.50 kg, and 532.60 kg, respectively. This base demonstrates The average yield per mu is 537.50 kg.

　　Xing'an League is located in the ecological circle of the southern foothills of the Greater Xing'an Mountains at 46°north latitude, a world-recognized cold rice golden belt.

However, it is also one of the world's three largest soda-saline-alkali land distribution areas. The salinity of the land is higher than six thousandths, which is a land where it is difficult to grow a single inch of grass.

　　As we all know, growing rice on saline soil is one of the three dreams of Academician Yuan Longping.

This technology can not only improve the ecological environment of saline-alkali land and desert areas, but also solve the problem of food rations for the poor in desert areas and double the income of growers.

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

　　The goal set by Academician Yuan Longping was "the yield per mu should be more than 300 kilograms."

In 2019, the average yield per mu of the base was 508.8 kg, and in 2020, the average yield per mu was 533.95 kg.

　　Now three years later, the once white saline-alkali land has long been transformed into a golden rice field, and rice output has been increasing year by year.

"Yuan Mengdao", named by Academician Yuan Longping himself, has also become a "dream rice" in the true sense.

　　Academician Yuan Longping once said that the Xing’an League Yuan Longping Rice Academician Expert Workstation develops and promotes "salt-alkali-tolerant hybrid rice" varieties and advanced technologies. After successful experiments, they can be promoted throughout northern China, and even to countries on the same latitude and in the same climate zone. Promotion.

　　Qi Shaowu, director of the National Hybrid Rice Engineering Technology Research Center, said that currently, the National Saline-Alkali Tolerant Rice Technology Innovation Center (hereinafter referred to as the center) has established research on saline-alkali-tolerant rice in Xing'an League of Inner Mongolia, Jiangsu, Wenchang, Hainan, Da'an, Jilin, and Beihai in Guangxi. base.

Concentrate the global rice scientific research strength in the center, select and breed high-quality varieties, improve good cultivation techniques, and strive to produce a result in 2-3 years.

　　“The area of ​​saline-alkali land in the world is very large. After Yuan Lao's wish of'turning saline-alkali land into fertile land' is realized, it will be a major contribution to the food security of China and the world." Qi Shaowu said.
