Organic biochar enzyme inhibiting slow-release fertilizer and production method thereof

Abstract

The invention provides an organic biochar enzyme inhibiting slow-release fertilizer and a production method thereof, and relates to the technical field of fertilizer production. The organic biochar enzyme inhibiting slow-release fertilizer is prepared from the following raw materials in parts by weight: 10 parts of potassium sulfate, 10 parts of monoammonium sulfate, 40 parts of urea, 18 parts of ammonium sulfate, 10 parts of a biochar enzyme inhibiting material, 5 parts of humic acid, and 7 parts of biochar powder, wherein the biochar enzyme inhibiting material is prepared from the following raw materials in parts by weight: 500 parts of polyaspartic acid, 400 parts of biochar powder, 5 parts of phosphate solubilizing bacteria, 5 parts of potassium bacteria, 60-80 parts of a nitrification inhibitor and 60-80 parts of a urease inhibitor. The organic biochar enzyme inhibiting slow-release fertilizer contains a certain amount of organic matters, and also comprises phosphate solubilizing bacteria, potassium bacteria, polyaspartic acid and urease inhibitor; with the biochar powder, propagation of microorganisms in soil is facilitated, the soil is improved, phosphate and potassium are solubilized, and loss of the slow-release fertilizer is controlled, so that not only is crop yield increased, but also waste recovery is realized, and the environmental pollution is reduced; the organic biochar enzyme inhibiting slow-release fertilizer belongs to environmental-friendly fertilizers.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to an organic biochar enzyme loss-controlled fertilizer and a production method thereof. Background technique [0002] According to the monitoring of the Ministry of Agriculture, the average utilization rates of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer in the three major food crops of rice, wheat and corn in the current season are 33%, 24% and 42% respectively. Among them, the utilization rates of nitrogen, phosphorus, and potassium fertilizers for wheat were 32%, 19%, and 44%, respectively; the utilization rates of nitrogen, phosphorus, and potassium fertilizers for rice were 35%, 25%, and 41%, respectively; and the utilization rates of nitrogen, phosphorus, and potassium fertilizers for corn were 32%, 25%, 43%. After any kind of fertilizer is applied to the soil, it cannot be completely absorbed and utilized by the crops, and part of it be...

Problems solved by technology

Our country loses as much as 12-14 million tons of chemical nitrogen through volatilization, denitrification, leaching and other ways every year. After the phosphorus in the existing compound fertilizer enters the soil, its effectiveness will drop by 80% in about 35-40 days, resulting in Waste of resources, pollute the environment
