Polypeptide compound fertilizer and preparation method thereof

Abstract

The invention discloses a polypeptide compound fertilizer and a preparation method thereof. The polypeptide compound fertilizer is prepared from the following chemical fertilizer raw materials in percentage by weight: 94-96 percent of a urea-based compound fertilizer and 4-6 percent of metalloprotease, wherein the urea-based compound fertilizer comprises 37-60 percent of urea, 10-30 percent of monoammonium phosphate, 10-36 percent of a potassium salt and 0-20 percent of a filling agent; and the filling agent is prepared from the following components of calcium carbonate metalloprotease in percentage by weight: 90 percent of polyaspartic acid, 0.5 percent of iron ions, 5 percent of salts and 4.5 percent of organized enzymes.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemical fertilizers, in particular to a polypeptide compound fertilizer and a preparation method thereof. Background technique [0002] According to statistics, in the total investment of agricultural agricultural materials, the input of chemical fertilizer accounts for about 50%, and a large amount of it is nitrogen fertilizer. However, the current utilization rate of chemical fertilizers in my country only accounts for about 30%. Most of the fertilizers seep into the ground, which has caused serious pollution of water sources, especially the part of nitrogen fertilizer that has not been effectively used seeps into the ground and is washed into rivers and soil layers of water, resulting in drinking water pollution. Seriously affect people's health. According to relevant experts, the amount of fertilization per unit area in China has reached 1.6 times that of the world's average, and the los...

AI Technical Summary

Problems solved by technology

The leading comrades of the Central Committee have repeatedly instructed that "the problem of improving the utilization rate of chemical fertilizers should be conscientiously done." In the past, slow-release and controlled-release of chemical fertilizers were done, but they only eased the absorption and did not solve the problem of effective plant absorption.
