Urea sulfate microbial fertilizer for peanut and preparation method of urea sulfate microbial fertilizer

Abstract

The invention discloses a urea sulfate microbial fertilizer for peanut. The urea sulfate microbial fertilizer comprises the following raw materials: 100-140 parts of urea sulfate, 120-180 parts of urea, 110-140 parts of potassium sulphate, 100-150 parts of potassium nitrate, 280-335 parts of monoammonium phosphate, 70-90 parts of a compound microbial agent, 60-70 parts of a urea sulfate sustainedrelease function fortifier, 18-22 parts of a urea sulfate fertilizer microbial growth promoter, 0-10 parts of filler, and 10-12 parts of an anticaking agent; the urea sulfate sustained release function fortifier comprises 50 parts of humic acid, 7 parts of nanometer dolomite powder, 2 parts of borax, 2 parts of ferrochel, 2 parts of nanosilicon dioxide, 1 part of chelated zinc, and 1 part of a nitrification inhibitor; the urea sulfate fertilizer microbial growth promoter comprises 6 parts of soluble starch, 4 parts of soluble dextrin, 3 parts of citric acid, 2 parts of water retaining agent, 1part of malic acid, 1 part of yeast powder, 1 part of sugar alcohol, 1 part of polyacrylic acid, and 1 part of fertilizer synergist. The ammonia volatilization amount is reduced by 30-40%, and the growth of the peanut on the seedling stage is promoted by 20-35%.

Description

technical field [0001] The invention relates to a special urea sulfate microbial fertilizer for peanuts and a preparation method thereof, belonging to the field of crop fertilizers. Background technique [0002] At present, the seasonal utilization of nitrogen fertilizer in my country's agriculture is 30-35%, and the loss rate is 60%. Among them, ammonia volatilization is the main loss route of nitrogen fertilizer. Under normal circumstances, the nitrogen lost by ammonia volatilization of ordinary compound fertilizers can reach 30-42% of the nitrogen application amount. The loss of ammonia volatilization reaches the maximum within 1-3 days of each nitrogen application. Ammonia volatilized in the air, under conditions of high humidity and high ammonia gas, and nitrogen dioxide in the air will promote the formation of sulfate, thereby aggravating the smog. This shows that, in addition to coal combustion, motor vehicle emissions and biomass burning, it is also very important...
