Compound amino acid microbial fertilizer for saline-alkali land and preparation method of fertilizer

Abstract

The invention discloses compound amino acid microbial fertilizer for saline-alkali land and a preparation method of the fertilizer. The compound amino acid microbial fertilizer for the saline-alkali land is prepared from corn residues, soybean curb residues, rice bran, a microbial agent, glycerin, ammonium chloride, magnesium sulfate, biotechnology fulvic acid, maleic anhydride, amino acid solutions of 40%-45%, industrial flour, fruit and vegetable residues, quail manure, earthworm soil, potassium permanganate and an adequate mount of water according to the weight proportion. The preparation method comprises the steps that microorganisms are cultured in organic matter rich in glycogen for enlarging culture, active substances such as amino acid are added, the survivability of microorganisms in soil of the saline-alkali land is strengthened, and due to the fact that the alkalinity of the soil of the saline-alkali land is high, the soil of the saline-alkali land is not suitable for growth of the microorganisms. According to the compound amino acid microbial fertilizer for the saline-alkali land, bonding is conducted through microorganism gel, the amino acid is added to improve the activity of the microorganisms, and enrichment and metabolism of the microorganisms facilitate improvement of soil property and soil fertility.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a compound amino acid microbial fertilizer for saline-alkali land and a preparation method thereof. Background technique [0002] The advantage of microbial fertilizer is that it can form a dominant population around the root system of plants through the massive reproduction of beneficial bacteria, which inhibits the life activities of other harmful bacteria. It can quickly decompose the organic matter in the soil, promote the formation of soil aggregates, loosen the soil through the activities of beneficial bacteria, and the soil's fertilizer retention, fertilizer supply, water retention, water supply and air permeability are all well regulated. At the same time, it can decompose the pesticide residues in the soil, prevent the residual pesticides from causing phytotoxicity to the next season's crops, and also decompose the harmful substances emitted during the ro...

Problems solved by technology

[0003] However, the shortcomings of microbial fertilizers are also obvious. The current situation is that there is generally a lack of high-efficiency strains and strain resources. Many manufacturers' strains are using the same strain, and the technology is relatively backward.
