Abstract

The invention relates to a long-acting nitrogen fertilizer containing nitrogen-fixing microorganisms. The long-acting nitrogen fertilizer is prepared from the following raw materials in parts by weight: 45 to 60 parts of urea, 2 to 6 parts of extract liquid of a urease inhibitor, 15 to 30 parts of humic acid, 10 to 20 parts of amino acid powder, 4 to 8 parts of extract liquid of a nitrification inhibitor, 4 to 8 parts of amino acid liquid, 0.5 to 1.5 parts of microorganism bacterial powder, 0.08 to 0.4 part of polyglutamic acid and 3.6 to 7.6 parts of glucosaminoglycan. According to the nitrogen fertilizer disclosed by the invention, the nitrogen-fixing microorganisms are combined with the nitrification inhibitor and the urease inhibitor, and various factors for regulating and controlling fixing and release of nitrogen are compounded and combined according to a scientific proportion and coating level, so that nitrogen release is effectively regulated and controlled, and nitrogen is guaranteed to be long-acting and effective.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a long-acting nitrogen fertilizer containing coated nitrogen-fixing microorganisms and a preparation method thereof. Background technique [0002] The average nitrogen utilization rate of grain crops in China is about 35%, which is 15 percentage points lower than that of developed countries, which is 50%. The main reason for the low utilization rate of nitrogen fertilizer is the volatilization loss of ammonium nitrogen, leaching loss of nitrate nitrogen and denitrification. The selection of slow-acting (long-acting) fertilizers can improve the utilization rate of fertilizers to a certain extent. Slow-acting fertilizer is to coat the surface of granular nitrogen fertilizer with a film, so that soluble nitrogen is gradually released for absorption and utilization by crops, reducing nitrogen loss. However, due to its high price, it is mainly applied to cash crops. [0003] In the study...
