Abstract

The invention discloses a composite microbial porous material for inhibiting saline-alkali soil from salinization and application of the composite microbial porous material. The composite microbial porous material is composed of composite microorganisms and a porous material. The raw materials comprise the following components in parts by weight: 20-30 parts of the composite microorganisms and 70-80 parts of the porous material. Complex microbial inoculants comprise tarlaromyces flavum, trichothecium roseum, verticillium chlamydosporium, trichoderma viride, lactobacillus acidophilus and bacillus subtilis. When the composite microbial porous material is applied, the composite microbial porous material is uniformly scattered on the surface of saline-alkali soil, and then ploughing is performed. When the composite microbial porous material is applied to saline-alkali soil, the growth of crops planted in the saline-alkali soil can be promoted, the crop yield can be increased, the salt content and pH value of the saline-alkali soil can be reduced, and the physical and chemical properties and ecological environment of the saline-alkali soil can be improved.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, and in particular relates to a composite microbial porous material for inhibiting saline-alkali land return to saline-alkali and its application. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil and various salinized and alkaline soils. Salinized soil contains a large amount of soluble salts, which increases the osmotic pressure of the soil solution, making it difficult for the roots of plants to absorb water, seriously affecting the growth of plants, and even making cultivation impossible. [0003] Vegetation restoration is an important means of improving saline-alkali land. It can reduce the evaporation of soil surface water, increase the number of plant roots in the soil, enhance the activity of soil microorganisms, reduce the accumulation of salt in the soil, and improve the physical and chemical properties of the soil...
