Preparation method of biological organic fertilizer

Abstract

The invention provides a preparation method of a biological organic fertilizer. The preparation method comprises the steps of fermentation substrate providing, fermentation substrate stacking and substrate fermentation, wherein the step of fermentation substrate stacking comprises the steps that a fermentation substrate and a fermentation liquid microorganism bacterium agent are evenly mixed and stacked to a rectangular fermentation substrate pile with the height of 0.5-0.8 m according to the proportion that 0.9-1.1 L of the fermentation liquid microorganism bacterium agent is added to every 1,000 kg of the fermentation substrate. The fermentation liquid microorganism bacterium agent comprises bacillus subtilis liquid, bacillus licheniformis liquid, saccharomyces cerevisiae liquid, lactic acid bacillus liquid and aspergillus niger liquid. By means of the preparation method of the biological organic fertilizer, waste materials can be changed into treasure, and the generally existing environmental pollution problems that when resourceful treatment of organic solid waste is conducted, the capacity for decomposing macromolecular protein and coarse fibers is weak, nitrogen is prone to loss, and pungent odors are produced can be solved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a fermented liquid microbial agent, a preparation method and a fermentation method thereof. Background technique [0002] At present, in terms of crop planting in my country, most of them still use chemical fertilizers. Although there is a certain amount of rent in terms of increasing production and income, long-term use will cause the following problems: [0003] 1. Destroy the soil, but the content of organic matter in the soil will decrease, resulting in an imbalance in the proportion of nutrients, acidification and hardening of the soil, which will affect the yield of crops; [0004] 2. The agricultural ecological environment is deteriorating. After applying chemical fertilizers to farmland, the actual utilization rate is only 30% on average, and most of them flow into rivers with farmland drainage, polluting the environment and endangering people's health. [0005] Therefore, at ...
