As China's urbanization process accelerates, arable land resources are becoming increasingly tense, and the red line of 1.8 billion mu of arable land is facing increasingly severe challenges. Saline and alkaline land is an extremely important reserve arable land resources and “potential grain silo”, China's saline and alkaline land area of 99.13 million hectares, it is of great significance to fully tap the potential of saline and alkaline land development and utilization. However, the current saline-alkali land improvement methods by means of engineering measures, physical measures, chemical measures and other means have many problems such as high cost and low improvement efficiency.
Research and practice in recent years have shown that the use of biotechnology to improve and manage saline and alkaline land has a significant effect.
Since 2023, our R&D personnel have collected soil samples from the saline-alkaline land of Qilihai Beach, the saline-alkaline land of the Second Company of a regiment of Xinjiang Construction Corps, the saline-alkaline land of Gaotuo, and the saline-alkaline land of Huanghua Experimental Field, etc. After repeated screening for more than a year, we have now obtained 13 kinds of saline-alkaline tolerant new strains, which were named HM-7, HM-8, HMF20, HMF21, HMF22, HMF23, HMF24, HMF22, HMF23, HMF24, HMF25, HMF26, HMF27, HMF28, HMF29, HMF30, these strains are more tolerant of saline and alkaline environments than the existing strains and have excellent overall performance. According to the introduction of microbiologists in our province, only Hebei University of Science and Technology, Biological Research Institute of Hebei Academy of Sciences and our company have excellent saline-tolerant strains in our province.
This progress will help develop new varieties of microbial fertilizers suitable for saline and alkaline land improvement, which is of great significance for saline and alkaline land improvement, increasing the quantity of arable land and improving the quality of arable land.
