Method for preparing instant biological organic fertilizer

Abstract

The invention discloses a method for preparing an instant biological organic fertilizer. The method comprises the following steps: (1) crushing a plant waste raw material to obtain powder residues; (2) performing fixation on the powder residues by adopting steam, the fixation temperature being 500 to 550 DEG C; (3) pressing and drying the powder residues subjected to fixation to form a block, removing water and performing deblocking; (4) adding enzyme microorganisms, wheat skin, a soybean cake, organic phosphorus and brown sugar into the deblocked powder residues, and performing uniform mixing to obtain a mixture; (5) performing repeated pressing blocking and deblocking operation on the mixture to finally obtain the organic fertilizer after deblocking. According to the method, by the repeated pressing blocking and deblocking operation, rapid fermentation is realized, and the organic fertilizer can be prepared within 48 hours, so that the preparation time for the organic fertilizer is greatly shortened; moreover, the prepared organic fertilizer is high in maturity, and damage to the roots of crops is prevented during application.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a preparation method of biological rapid organic fertilizers. Background technique [0002] Organic fertilizer, commonly known as farmyard manure, is mainly derived from plants and / or animals. It is applied to the soil to provide plant nutrition as a carbon-containing material. It is processed from biomass, animal and plant waste, and plant residues to eliminate It is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus and potassium, which can not only provide comprehensive nutrition for crops, but also have long fertilizer effects, which can increase and Renewing soil organic matter, promoting microbial reproduction, improving soil physical and chemical properties and biological activity are the main nutrients for green food production. [0003] The production of organic ...

Problems solved by technology

[0004] Therefore, conventional organic fertilizer composting fermentation has problems such as slow decomposition speed, long time consumption, and serious environmental pollution. Moreover, the organic fertilizer prepared by composting fermentation cannot be fully decomposed, and the application of incompletely decomposed organic fertilizer is likely to cause root burn of crops.
