Abstract

The invention discloses a biosurfactant composition for soil improvement. The biosurfactant composition is prepared from the following raw materials in parts by weight: 2-20 parts of a composite microbial flora, 20-50 parts of an organic fermentation substance, 15-40 parts of shell powder, 10-30 parts of starch, and 5-30 parts of inorganic salt. The biosurfactant composition for soil improvement, provided by the invention, is prepared by mixing a microbial preparation with the organic fermentation substance, the shell powder, the starch and the inorganic salt, the soil improvement type microbial preparation is obtained through combination of at least two kinds of streptomyces fradiae, photosynthetic bacteria, acidithiobacillus ferrooxidans, bacillus mucilaginosus, bacillus subtilis and bacillus laterosporus, and through a composite of the biological preparation and chemicals, the microenvironment of soil is regulated, so that the growing environment of crops can be improved, and the purpose of increasing the yield per unit area of the crops is realized.

Description

technical field [0001] The invention relates to the technical field of agricultural bioengineering, in particular to a biosurfactant composition for improving soil. Background technique [0002] Soil is the material basis for the growth of crops. The amount of soil organic matter, the strength of soil fertility, the quality of soil aeration and the balance of soil solution play a decisive role in the growth of plants. my country feeds 22% of the earth's population with 7% of the arable land. In order to increase crop yields, farmers generally use fertilizers such as manure, chemical fertilizers and compound fertilizers. Fertilizer occupies a very important position in my country's grain production, and is one of the largest material investments in farmers' productive investments. At present, the overall level of scientific fertilization in China is not high, and the application of chemical fertilizers has become the main measure to increase agricultural production. The lon...
