Production and preparation method of selenium-rich biological organic fertilizer

Abstract

The invention discloses a production and preparation method of a selenium-rich biological organic fertilizer. The method comprises the following steps of: preparing materials; preparing a microbial compound inoculum; preparing a fermentation material; and carrying out biological fermentation. The method has the advantages that fermentation treatment is carried out on excrements of livestocks and crop straws, so that waste is changed into a precious resource; environmental pollution of the excrements is solved; the soil is improved; the preparation method is simple, good in effect and low in treatment cost; not only are a fermentation effect and the fertilizer efficiency improved, but also a selenium-rich effect is obvious by adding the microbial compound inoculum; a disease prevention effect also can be achieved; the economic benefit is also improved.

Description

technical field [0001] The invention relates to a bio-organic fertilizer, in particular to a method for producing selenium-enriched bio-organic fertilizer by using livestock and poultry manure and crop stalks, and belongs to the field of bio-organic fertilizers. Background technique [0002] In recent years, various bio-organic fertilizers have been widely used in my country. They have made outstanding contributions to reducing the use of chemical fertilizers, purifying the soil environment, improving crop quality and food safety, and greatly promoting the sustainable development of agriculture. At present, bio-organic fertilizers generally use straw or manure as raw materials, which has certain significance for environmental protection and sustainable agricultural development. However, most bio-organic fertilizers are not scientifically formulated according to actual application, the decomposing fermentation is not standard, and the strains are used improperly, etc., result...

AI Technical Summary

Problems solved by technology

However, most bio-organic fertilizers are not scientifically prepared according to actual application, the decomposing fermentation is not standard, and the strains are used improperly, etc., resulting in burning roots and seedlings, fertilizer efficiency and fertilizer effect period are comparable to chemical fertilizers, and poor soil improvement.
