Selenium-rich amino acid-microbe organic fertilizer

Abstract

A selenium-rich amino acid-microbe organic composite fertilizer is prepared through the following steps: preparing an aqueous solution of composite amino acids, preparing fermentation powder, preparing a selenium-rich organic compost, preparing a microbial agent, and preparing the amino acid-microbe organic fertilizer. The selenium-rich amino acid-microbe organic composite fertilizer has the following advantages: pure plant rhizomes are adopted as a raw material to produce amino acids, selenium ore powder and selenium-rich straws are adopted to make the organic compost, and the organic compost and the amino acids are combined to form a material which is easily absorbed as a fertilizer, so the amino acids and the organic fertilizer are simultaneously provided, the survival rate of microbes is improved, and a low-temperature production process also guarantees the validity of the amino acids and the survival environment of the microbes; and the organic fertilizer prepared through the method can guarantee the quality of products, effectively improves the output and the selenium content of crops, greatly improves the quality of the products, improves the soil composition, improves the soil fertility, and is suitable for large-scale popularization.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, in particular to a selenium-rich amino acid microbial organic fertilizer. Background technique [0002] Organic fertilizer can improve soil, improve soil fertility, restore soil to normal ecological balance, increase soil organic matter content, form aggregate structure, improve soil air permeability, water retention, and fertilizer retention performance, which is conducive to the growth of crop root systems and improves plant quality. and yield. It can effectively improve the utilization rate of chemical fertilizers, decompose pesticide residues, improve crop quality, and produce pollution-free food. Organic fertilizers can reduce the harm of agricultural products to humans and animals caused by excessive application of chemical fertilizers; on the other hand, the inorganic and organic nutrients contained in organic fertilizers can directly provide nutrients for crops, which is co...

Problems solved by technology

[0005] Therefore, in recent years, selenium-enriched fertilizers have been widely used in the field of fertilizers, but selenium-enriched fertilizers containing amino acids have not been found

At the same time, a large amount of amino acids in the existing amino acid organic fertilizers come from animal fertilizers, or animal and plant mixed fertilizers, which are not easily absorbed and utilized by crop roots, or the absorption and utilization rates are not high

In addition, when amino acids are combined with organic fertilizers, trace element fertilizers, or macronutrient fertilizers, high-temperature processing is used in production, especially when microbial fertilizers are combined without consideration of the presence of high-temperature carriers, resulting in a large amount of amino acids and microorganisms during processing. loss, which seriously affects the quality and application effect of fertilizer
