Problems solved by technology

In addition, in the process of crop planting, due to the long-term unreasonable use of fertilizers and pesticides, such as the application of high-nitrogen and high-phosphorus chemicals to regulate crop growth and increase crop yields, and the long-term application of chemical phosphorus-containing pesticides, the single If the nutrient concentration is too high, it will not only cause the stock of physical phase reaction in the soil to be too large, but also produce harmful substances in the soil, and become the main factor causing soil compaction in some areas, resulting in a decrease in crop yield and a decrease in the quality of agricultural products

Abstract

The invention discloses compound microbial fertilizer, which is prepared from the following effective components: urea phosphate, polyglutamic acid and a microbial agent. The invention also provides apreparation method and use of the composition. The test results show that the composition provided by the invention can well regulate the acid-base balance of the soil, promote the health of crops and increase the yield of the crops.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemical fertilizers, and relates to a functional compound fertilizer, in particular to a compound fertilizer comprising urea phosphate, polyglutamic acid and microbial bacterial agents. Background technique [0002] Polyglutamic acid (γ-poly-glutamic acid, referred to as γ-PGA), also known as natto gum and polyglutamic acid, is a water-soluble, biodegradable, non-toxic, biologically produced by microbial fermentation. polymer. Polyglutamic acid is a type of homopolyamino acid polymerized by glutamic acid monomers through amide bonds. It has excellent biodegradability, super adsorption, and non-toxicity. Adding it to compound fertilizers can reduce Nutrient loss of fertilizer, improve fertilizer utilization rate, regulate plant growth and other multiple functions. It has significant application effects on rice, wheat, corn, vegetables, fruit trees, flowers and other plants, and can signific...
