Abstract

The invention discloses a preparation method of a crop straw organic fertilizer, which comprises the following steps: (1) boiling bean pulp and soybean, and carrying out solid-liquid separation; uniformly mixing the boiled bean pulp soybean, bean pulp soybean water, rice bran, corn straw powder and EM (effective microorganism) bokashi, and fermenting in a sealed environment to obtain a fermentation material a; (2) pulverizing the straw, mixing with the fermentation material a, and fermenting to obtain a fermentation material b; (3) dissolving an EM stock solution and molasses in water to prepare an EM fermentation liquid; and (4) mixing the fermentation material b and EM fermentation liquid, and fermenting by a gradient fermentation process. The crop straw organic fertilizer fully utilizes the farmland straw waste, and is simple and efficient in the fermentation technique. The EM organic fertilizer has favorable fertilizer efficiency, can be used instead of the chemical fertilizer to reduce the environmental pollution caused by the chemical fertilizer and also reduce the air pollution caused by straw combustion, can improve the soil structure to some extent, and especially can improve the soil hardening caused by abundant use of the chemical fertilizer.

Description

technical field [0001] The invention relates to a preparation method for fermenting waste stalks by living microorganisms to generate organic fertilizer, which belongs to the field of agricultural microorganisms. Background technique [0002] Chemical fertilizers are the most basic and one of the most important material inputs for agricultural production. Long-term application causes soil compaction, nutritional imbalance, accelerates soil acidification, reduces the activity of microorganisms in the soil, and makes it difficult for substances to be transformed and degraded. Soil compaction refers to the lack of organic matter on the soil surface, poor structure, structural damage and soil material dispersion under the action of external factors such as irrigation or rainfall, and the soil surface is hardened by cohesive force after drying. [0003] Bio-organic fertilizer is a new type of fertilizer recommended by the Ministry of Agriculture and the General Administration of ...
