Microbial manure of chelates of composite amino acid in use for spray irrigation, drop irrigation, and production method

Abstract

This invention discloses a method for preparing microbial compound fertilizer chelated with trace elements for spray and drop irrigation. The method comprises: hydrolyzing raw material of protein wastes to obtain composite amino acids, adding trace elements to chelate composite amino acids, and combining with beneficial bacteria (azotobacter, phosphorus fertilizer bacteria, potassium bacteria, bacillus, etc.) to obtain the microbial compound fertilizer. The microbial compound fertilizer has obvious nitrogen fixation, phosphorus and potassium leaching, and growth promotion functions, and has high utility. The release speed is controllable, and the microbial compound fertilizer can improve and activate soil, and improve crop quality.

Description

technical field

[0001] The invention relates to a strain and its composition in the field of microbial fertilizers, in particular to a microbial fertilizer for spraying and drip irrigation of compound amino acid chelates and a production method thereof. Background technique

[0002] Fertilizer is the "food" and "nutrition" of crops. The emergence of chemical fertilizers and balanced fertilization technology is the product and important symbol of the first agricultural industrial revolution. my country's current chemical fertilizer use per unit area is 1.6 times the average level of the United States and the world, and the total annual use is about 120 million tons. In the past 10 years, the total amount of chemical fertilizers in my country has increased by 90.7%. At present, the application amount of pure nitrogen per hectare has reached 184 hectares, which is 12.3 kilograms per mu. The output has only increased by 9.1%, and the loss rate of nitrogen fertilizer is as high a...
