Abstract

The invention discloses a method for improving the adaptive capacity of soybeans in saline-alkali soil. The method includes the steps that nutrient soil and perlite are mixed evenly to serve as bacterial manure matrixes, and then nodule bacteria fluid and the bacterial manure matrixes are mixed and stirred evenly to serve as nodule bacteria manure; soybean seedlings are transplanted into the nodule bacteria manure and are cultivated under the condition with the temperature being 23 DEG C to 27 DEG C, the illumination intensity being 2,000 lx to 2,500 lx and the illumination time being 12 h / d. The method utilizes the nodule bacteria manure to promote the whole plant fresh weight of the soybeans to be increased by from 22.50% to 125% in the soil with high-concentration salt, remarkably improves the salt tolerance related-gene expression level of the soybeans, and improves the mRNA expression level of peroxidases like APX and SOD by three times to eight times.

Description

[0001] (1) Technical field

[0002] The invention relates to a method for growing soybeans in saline-alkali land, in particular to a method for promoting the growth of soybeans in saline-alkali land by utilizing rhizobia fertilizer.

[0003] (2) Background technology

[0004] my country is the birthplace of soybean cultivation, with a cultivation history of more than 3,000 years. In recent years, the problem of soil salinization has increasingly threatened the limited land resources that human beings rely on for survival. However, with the development of the national economy and the improvement of people's living standards, as well as the development of processing industry, food industry and animal husbandry, my country's demand for vegetable protein has increased sharply. Soybeans from the United States and South America make up. Insufficient soybean production has become an important obstacle to the national policy of "basically relying on domestic food supply", and has also...
