Abstract

The invention discloses a microbial decomposition agent and an organic fertilizer for improving saline-alkali soil. The microbial decomposition agent is prepared from aspergillus griseus, tarlaromycesflavus, aspergillus niger, trichoderma harzianum, verticillium chlamydosporium and bacillus licheniformis. The preparation process of the organic fertilizer comprises the following steps: 1) adding adecomposition agent into clear water, mixing to form a suspension, uniformly spraying the suspension on the surfaces of organic fertilizer particles, and controlling the water content of the organicfertilizer particles to be less than or equal to 20%; (2) preserving the organic fertilizer particles treated in the step (1) at the temperature of 10-30 DEG C, and drying the organic fertilizer particles in a shade place when white hyphae grow on the surfaces of the organic fertilizer particles; and 3) when the white hypha turns black, finishing the production of the organic fertilizer for improving the saline-alkali soil. The microbial decomposition agent disclosed by the invention can increase microorganisms in the organic fertilizer, and the organic fertilizer treated by the microbial decomposition agent can promote the growth of crops planted in saline-alkali soil, reduce the pH value of the saline-alkali soil and improve the physical and chemical properties of the soil.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, and in particular relates to a microbial decomposing agent and an organic fertilizer for improving saline-alkali land. Background technique [0002] Saline-alkali soil is a general term for all kinds of saline soil and alkaline soil. There are a large number of weakly acidic anions (CO 3 2- 、HCO 3 1- ) and a large number of monovalent cations (Na + ), high pH, ​​poor soil structure and low organic matter content. Therefore, the original saline-alkali soil seriously affects the growth of planted crops. [0003] Organic fertilizers are rich in organic matter and nutrients needed for crop growth. When applied to saline-alkali soil, it can increase nutrients and organic matter in the soil, reduce soil bulk density, and improve soil physical and chemical properties. [0004] Through their own metabolism and activities, soil microorganisms can produce a large amount of orga...
