The article highlights the advancements in agricultural research in the Yellow River Delta, focusing on the development of a new soybean variety and innovative farming techniques to cultivate crops on saline-alkali lands. This initiative, located in the Shandong Province, aims to leverage around 550 million acres of previously unusable land, boosting arable space and enhancing crop yields. The new soybean variety is not only salt and alkali tolerant, but also enhances its nutritional value, including isoflavones. The region has adopted a pipeline water saving and salt reduction technology, which has dropped soil salinity levels and saved water by 38%. Additionally, the use of self-developed microbial agents, precision fertilization, and biological pest control methods have led to a 35% increase in vegetation coverage and over 30% increase in biological carbon sequestration. The area has also seen the development of 15 new quinoa varieties and 226 varieties of other plants, with 18,000 salt-tolerant germplasm resources collected and 37 new varieties bred for saline-alkali environments.

Xinhua News Agency, Jinan (Reporters Chen Guofeng and Zhang Wuyue) It is late autumn, and the Yellow River Delta has high air and clear skies. In the endless farmland, breeding researchers broke a pod with their hands, and a few full soybeans rolled down from it. Recently, soybeans in the Yellow River Delta Agricultural High-tech Industry Demonstration Zone in Shandong Province have entered the harvest period. This new variety, selected from the unique wild soybean resources of the Yellow River Delta, has significantly improved the ability to tolerate saline and alkalis, with a yield of more than 400 jin per mu. The yield of common varieties of alkaline land is equivalent. "Soybeans produced on saline-alkali soils have better quality and are also rich in isoflavone active substances, which can improve soybeans' salt-tolerant, nitrogen-fixing and antioxidant capacity." Luo Shouyu said that they also used spaceborne radiation mutation breeding and field screening to make soybean ...
