Compound slow release fertilizer for increasing quality of mat rush

Abstract

The invention discloses compound slow release fertilizer for increasing the quality of mat rush. The compound slow release fertilizer is prepared from the following raw materials in parts by weight: 60 to 80 parts of compound urea, 40 to 50 parts of monopotassium phosphate, 30 to 40 parts of potassium nitrate, 25 to 35 parts of organic fertilizer, 2 to 4 parts of vermiculite powder, 2 to 4 parts of bentonite, 2 to 4 parts of rectorite, 1 to 2 parts of expanded perlite, 2 to 4 parts of molybdenum-containing mineral slag, 3 to 5 parts of trace element fertilizer, 0.02 to 0.04 part of compound enzyme and 0.06 to 0.12 part of compound bacteria, wherein the compound urea is prepared by adopting the following technology: dispersing urea in a sodium hydroxide solution, adding sodium sulfite and stirring, adding maize germ protein and continuously stirring, regulating the pH (Potential of Hydrogen) of a system to be neutral, regulating the temperature of the system, adding glutamine transaminase and stirring, and inactivating at a high temperature, thus obtaining the compound urea. According to the compound slow release fertilizer disclosed by the invention, seeds and seedlings of the matrush are pure, germination is strong, the quality of the seeds of the seedlings of the mat rush is remarkably increased, the seeds and the seedlings of the mat rush are purified and rejuvenated, quicktillering of the mat rush can be facilitated, and the output rate of the mat rush can be increased.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound slow-release fertilizer for improving rush quality. Background technique [0002] For a long time, the farming system in rush-producing areas has been dominated by "rush-late rice". In order to ensure high yields of late rice, late rice must be planted immediately after harvesting the rush. Therefore, the short grass that does not meet the standard in the agricultural season is burned by farmers. . [0003] Rush planting uses a large amount of fertilizer and has good short-term fertilizer efficiency, but its sustainable support ability is poor. Rush is prone to nutritional imbalance. When the rush is harvested, the length of a large number of rushes does not meet the standard, and the harvest season coincides with the rainy season, so a large amount of waste grass is burned. Not only waste of resources, but also the smog it produces will endanger the safety of air...

[0003] Rush planting uses a large amount of fertilizer and has good short-term fertilizer efficiency, but its sustainable support ability is poor. Rush is prone to nutritional imbalance. When the rush is harvested, the length of a large number of rushes does not meet the standard, and the harvest season coincides with the rainy season, so a large amount of waste grass is burned. Not only waste resources, but also the smog it produces will endanger the safety of aircraft taking off and landing and high-speed traffic
