Abstract

The invention discloses a preparation method of a straw organic fertilizer. The preparation method includes the steps of 1) boiling soybean meal, peanut meal and rapeseed meal, performing solid-liquid separation and cooling, and uniformly mixing meal solids, meal nutrient liquids, corn straw powder and EM bokashi, and sealing the mixture; 2) crushing straw and mixing the straw with a fermentation material A to perform fermentation; 3) dissolving an EM stock solution and molasses in water to prepare an EM fermentation liquid; and 4) mixing a fermentation material B with the EM fermentation liquid, performing fermentation in a gradient fermentation manner. In the straw organic fertilizer, farmland straw wastes are fully utilized. The fermentation technology is simple and high-effective. The EM organic fertilizer has excellent effects, can be used for replacing chemical fertilizers and reduces the environment pollution caused by the chemical fertilizers and also reduces air pollution caused by straw combustion. In addition, the straw organic fertilizer can improve soil structure in certain degree, and especially, solve a problem of soil hardening due to large use quantity of chemical fertilizers.

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 ...
