Problems solved by technology

Microbial ecological fertilizers have the advantages of slow decomposition and release without causing soil pollution. Microorganisms can also decompose plant residues in the soil, improve crop resistance, and release nutrients in the soil. Therefore, research on microbial ecological fertilizers has become a key to improving soil Popular, but the microbial ecological fertilizers currently used in research are mostly mixed and granulated with microorganisms, organic and inorganic fertilizers. However, microorganisms are coated in granules. Anoxic environment and excessive inorganic fertilizer content will cause some microorganisms to die. ;Because the high humidity inside the granules will also cause a large number of microorganisms to multiply, resulting in a decrease in the shelf life of the fertilizer; considering that high temperature will cause the death of microorganisms, low-temperature drying is used in the drying process of granules, which increases the drying cost

Abstract

The invention discloses amino acid microbial ecological fertilizer and a preparation and using method thereof. The preparation method of the amino acid microbial ecological fertilizer comprises the steps that 1, an organic matter substrate is prepared, wherein the organic matter substrate is amino acid particles; 2, bacterial strains are selected and prepared into powder; 3, an organic coating agent is prepared, wherein caramel pigment and water with the mass ratio being 1:3-10 are evenly mixed at the temperature of 30-60 DEG C, and therefore the organic coating agent is obtained; 4, 500-1000 parts by weight of the amino acid particle organic matter substrate is coated with 1-10 parts by weight of the organic coating agent, then 2-15 parts by weight of the powder is evenly stuck to the organic coating agent, and therefore the amino acid microbial ecological fertilizer is obtained. The preparation method of the amino acid microbial ecological fertilizer has the advantages that microorganism death can be effectively avoided, and the shelf life of the fertilizer can be prolonged.

Description

technical field [0001] The invention relates to the technical field of ecological fertilizers, in particular to an amino acid microbial ecological fertilizer and its preparation and use methods. Background technique [0002] In recent years, a large amount of chemical fertilizers have been used in agricultural development to increase production. However, the extensive use of chemical fertilizers has gradually deteriorated the soil condition. The worse the soil, the more fertilization, and the more fertilization, the worse the soil. Fertilization and soil quality have entered a vicious cycle; soil organic matter content Problems such as decline, compaction, poor tillability, and weakened fertilizer and water retention capabilities make this a serious threat to the sustainable development of agriculture in my country. How to improve the quality of cultivated land soil has always been our concern. Excessive use of chemical fertilizers, especially nitrogen fertilizers, depletes s...
