Abstract

The invention discloses a microbial preparation for improving soil fertility of saline-alkali soil and a preparation method thereof. The microbial preparation is mainly prepared from the following rawmaterials: compound microorganisms, white sugar, urea, glutamine, oil bran, corn flour, wheat bran, rice chaff and zeolite powder. The preparation process of the microbial preparation comprises the following steps: step 1, adding the single microbial agents forming the compound microorganism together according to a preset proportion, and uniformly mixing to obtain the compound microorganism; step2, adding the components of the raw materials together according to a set weight ratio, uniformly mixing, adding clear water, and stirring and mixing to adjust the moisture content of the materials;and step 3, fermenting the material obtained in the step 2 at the temperature of 18-28 DEG C to obtain the microbial preparation. When the microbial preparation is applied to saline-alkali soil, the growth of crops planted in the saline-alkali soil can be promoted, the salt content and the pH value of the saline-alkali soil are reduced, and the physical and chemical properties of the soil are improved.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, and in particular relates to a microbial preparation for improving soil fertility of saline-alkali land and a preparation method thereof. Background technique [0002] Saline-alkali soil is a general term for all kinds of salinized soil and alkaline soil. Soil salinization makes farmland uncultivable, soil economic benefits are low, and land resources are wasted. However, saline-alkali land can be transformed into arable land after improvement, which is of great significance to the sustainable development of agriculture. [0003] The biological improvement of saline-alkali land does not destroy the ecological environment. It mainly improves soil physical and chemical properties and soil microclimate by introducing, screening and planting salt-tolerant plants. [0004] Microorganisms in the soil can produce abundant metabolites in their own metabolic process. These metabo...
