Recently, a collaborative research project between Changshuihe Farm of Beidahuang Group and Zhengzhou University of Light Industry has achieved a key breakthrough in the development of superior native soybean rhizobia. After two months of dedicated research and repeated trials, the project successfully extracted high-quality bacterial strains adapted to local conditions. The accompanying liquid and ultra-fine powder formulations of the strains have been delivered to the farm and are set to begin field demonstration applications.
This notable achievement in collaborative innovation between the farm and university was led by the research team headed by Professor Zhang Junjie from Zhengzhou University of Light Industry. Adhering to the core principle of "adapting to local conditions and precise matching," the team collected soil samples from the farm to explore local microbial resources. Using the locally cultivated variety "Heihe 43" as the experimental carrier, the team conducted multiple rounds of meticulous operations including isolation, purification, and screening, ultimately cultivating dominant strains.
Compared to imported rhizobia strains, the successfully extracted high-quality rhizobia are all native strains screened from local soil. They not only exhibit strong environmental adaptability and exceptional stress resistance, enabling them to quickly "take root" in local climate and soil conditions, but also help reduce fertilizer usage and lower planting costs, significantly enhancing soybean nodulation and nitrogen fixation efficiency.
After promotion, the project is expected to steadily increase soybean yield per unit area, optimize the industrial structure, and lay a solid technological foundation for the high-quality development of the soybean industry in the region. This initiative serves as a vivid practice of the "storing grain in technology" strategy in the field.
