Problems solved by technology

[0002] The general growth period of summer maize in the Yellow River Basin is about 105 days, and the critical period of fertilization is the big bell mouth period, that is, 50 days after sowing. Fertilizer needs, it is difficult to solve the nitrogen demand problem of summer maize by one-time application of nitrogen fertilizer
[0003] Utilizing coated and controlled-release materials, controlling the conversion and slow release of nitrogen fertilizers through blending or coating is a common method to improve the efficiency of nitrogen fertilizer use, but the application of pelletization technology in fertilizers has not been reported

Abstract

The invention discloses a summer corn special pesticide fertilizer and a production method thereof. The summer corn special pesticide fertilizer is prepared by using small particle urea as an inner core, pelleting by adopting a pelleting material, and coating by adopting a coating agent, wherein the pelleting material comprises mono-ammonium phosphate, potassium chloride, nitrohumic acid, borax, zinc sulfate heptahydrate, amino acid chelate rare earth, DMPP (dimethyl-phenyl-piperazinium) and a suspensoid solution; the coating agent comprises the following components in percentage by weight: 15% of chlorpyrifos granules, 20% of moroxydine hydrochloride-copper acetate wettable powder, 70% of thiram wettable powder and the balance of a film-forming agent, pearl powder, titanium pigment and dyestuff. By virtue of pelleting, coating and using a controlled release material, the fertilizer effect period of urea is prolonged from about 15 days to 50 days and is released in a centralized mode during big flare opening period of the summer corn, the fertilizer effect period of a nitrogenous fertilizer and the utilization ratio of the nitrogenous fertilizer are greatly improved, and the output is increased. The summer corn special pesticide fertilizer can control aphids, root rot, viral diseases and the like during the seeding stage of the corn, and the effect of controlling maize rough dwarf disease is particularly significant.

Description

technical field [0001] The invention relates to a special medicinal fertilizer for summer corn and a production method thereof, belonging to the technical field of medicinal fertilizer integration. Background technique [0002] The general growth period of summer maize in the Yellow River Basin is about 105 days, and the critical period of fertilization is the big bell mouth period, that is, 50 days after sowing. It is difficult to solve the nitrogen demand problem of summer maize by one-time application of nitrogen fertilizer. [0003] The use of coated and controlled release materials to control the conversion and slow release of nitrogen fertilizers through blending or coating is a common method to improve nitrogen use efficiency, but the application of pelletization technology in fertilizers has not been reported. How to realize one-time basal application by pelletization technology to solve the fertilizer needs of summer corn during the whole growth period, and how to ...
