Amino acid microorganism coating fertilizer and preparation method thereof

Abstract

The invention discloses an amino acid microorganism coating fertilizer and a preparation method thereof. The method comprises the following steps: mixing 5-10 parts of hydrolyzed feather meal, 5-10 parts of soybean meal powder, 15-20 parts of borax, 45-50 parts of ammonium nitrate, 15-20 parts of monoammonium phosphate, 30-40 parts of potassium sulfate, 0.2-1 part of humic acid, and 0.7-3.5 parts of trace elements by weight part, granulating a mixture to obtain material granules; and coating the surface of the material granules with 0.2-1 part of bacillus subtilis and 0.2-1 part of bacillus megaterium. According to the method, matching of the hydrolyzed feather meal containing free amino acids and soybean meal powder is used as a composite amino acid donor, the inorganic components and the organic components are combined for granulation, the surface of the material granules with a composite microbial agent, and the efficacy loss of amino acid and microorganism during a processing step is reduced; the amino acid microorganism coating fertilizer contains a plurality of nutrition promotion components such as thiamine, riboflavin, nicotinic acid and choline, other nutrient compositions are combined for matching, so that the fertilizer efficiency quality can be performed in a more stable mode.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to an amino acid microorganism-coated fertilizer and a preparation method thereof. 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. 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 conducive to the absorption of crops and the improvement of quality, and strengthens the soil. Enzyme activity. The activity of microorga...

Problems solved by technology

[0004] However, the existing amino acids are largely derived from animal fertilizers or mixed animal and plant fertilizers, which are not easily absorbed and utilized by crop roots, or the absorption and utilization rates are not high

At the same time, when amino acids are combined with organic fertilizers, trace element fertilizers, or macronutrient fertilizers, high-temperature processing is used, especially when combining microbial fertilizers, the presence of high-temperature carriers is not considered, resulting in a large amount of amino acids and microorganisms during processing. loss, which seriously affects the quality and application effect of fertilizer

In addition, in the existing amino acid microbial organic fertilizer and in the product combination of compound bacterial fertilizer, the combination of organic components, inorganic components and microbial strains is too high or too low, showing obvious randomness, and the quality gap of the same type of products is very large. Large, affecting the effect of compound fertilizer
