Abstract

The invention discloses a bio-organic fertilizer capable of improving saline-alkali soil. The bio-organic fertilizer is mainly prepared from raw materials consisting of a complex microbial inoculant,animal waste and molasses. The complex microbial inoculant comprises aspergillus glaucus, tarlaromyces flavus, trichothecium roseum, trichoderma koningii and verticillium chlamydosporium. The bio-organic fertilizer is prepared by uniformly mixing the main raw materials, then adjusting the water content of the mixed material to 30-80%, and carrying out facultative fermentation at a temperature higher than 10DEG C for 10-60 days. The bio-organic fertilizer can promote the growth of crops planted in saline-alkali soil, reduce the salt content of the saline-alkali soil, and improve the soil physicochemical properties and ecological environment of the saline-alkali soil.

Description

technical field

[0001] The invention belongs to the technical field of saline-alkali land improvement, and in particular relates to a bio-organic fertilizer capable of improving saline-alkali land. Background technique

[0002] Saline-alkali soil is a general term for all kinds of salinized soil and alkaline soil. High salinity components in saline-alkali land will cause poisonous crops, thereby inhibiting the growth and development of crops, lacking seedlings, reducing production or even dying. 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 pla...
