Pesticide and fertilizer composition containing potassium phosphite and polyglutamic acid

Abstract

The invention discloses a pesticide and fertilizer composition. Effective components of the composition contain potassium phosphite and polyglutamic acid. The invention also provides a preparation method and a use of the composition. A test result shows that the composition can promote the health of crops, increase the yield of the crops and prevent and control diseases of the crops.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemistry, and in particular relates to a medicinal fertilizer composition comprising potassium phosphite and polyglutamic acid. 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 significantly increase crop yield. [0003] Potassium Phosphite (...

Problems solved by technology

[0005] Due to the long-term unreasonable application of chemical pesticides and chemical fertilizers, the soil pollution has intensified, and the single nutrient concentration in the soil is too high, which not only causes the stock of physical phase reactions in the soil to be too large, but also produces harmful substances in the soil, and has become a cause of The main factor of soil compaction in some areas leads to a decrease in crop yield and a decrease in the quality of agricultural products. At the same time, since most pesticides and fertilizers cannot be applied at the same time or affect their respective effects when applied together, pesticides and fertilizers need to be applied separately, which increases labor costs.
