Abstract

The invention provides an organic fertilizer for improving saline soil and a preparation method thereof. The organic fertilizer is prepared through a technology of combining three-step fermentation and a compound pelletizing method by taking wheat straw as the main raw material and being assisted by effective active strains such as bacillus psychrosaccharolyticus, EM bacteria, nitrifying bacteria and bacillus megaterium; the organic fertilizer has the effects of organic fertilizers and bio-organic fertilizers, is rich in natural organic nutrients and contains a large number of probiotics, soil hardening can be broken, the balance of microorganisms in soil is effectively adjusted, the phenomena of soil salinization caused by relying on fertilizer abuse all year round and the like can be eliminated, water and fertilizer penetration of the oil is enhanced, stress resistance of crops is improved, the yield of the crops is increased, and the quality of agricultural products is improved; releasing of organic matter in the soil can be promoted by the organic fertilizer, the physical and chemical structure of the saline soil is improved, agglomerates and permeability are improved, the soil fertility is improved, and the organic fertilizer is a good plant area soil modifier.

Description

technical field [0001] The invention relates to an organic fertilizer for improving saline-alkali soil and a preparation method thereof, belonging to the field of fertilizer processing. Background technique [0002] Soil salinization is usually the process of salt accumulation in the soil caused by the rise of the groundwater table due to improper irrigation, excessive water use, etc., which mainly occurs in arid, semi-arid, semi-humid climate areas and coastal lowland areas irrigated by seawater , while soil salinization in agricultural planting areas is mainly due to the extensive application of chemical fertilizers. The total area of ​​saline land in my country is 1.487 billion mu, of which 554 million mu is modern saline soil, 260 million mu is potential salinized soil, and 140 million mu of cultivated land is affected by salinization. They are mainly distributed in Xinjiang, Hexi Corridor, The Hetao Plain, the Huanghuaihai Plain, the western part of the Northeast Plain,...
