Preparation method of rice fertilizer

Abstract

The invention provides a preparation method of a rice fertilizer. The method comprises the following steps: mixing urea, diammonium phosphate, a calcium magnesia phosphate fertilizer, potassium chloride, borax, a sulfate fertilizer and medical stone to obtain a mixture A; putting nano carbon into wine, and carrying out ultrasonic treatment in a water bath to obtain a mixture B; extracting nutrient components in watermelon peel, banana peel, algae and fructus momordicae, preparing a yellow meal worm-omphisa fuscidentalis hampson-silkworm pupa-indigofera neopolygaloides mixed solution, carrying out enzymolysis on reed, wheat straw, festuca arundinacea, ryegrass, Pennisetum hydridum and corn pasture, and mixing the enzymolysis product, the extract, the mixed solution, a rare-earth micro fertilizer and an organic fertilizer to obtain a mixture C; putting a first filter residue, azotobacter, chicken, chicken livers, saccharomycetes, dried vinasse and deionized water into a fermentation tank, and carrying out anaerobic fermentation to obtain a mixture D; mixing the mixture A, mixture C and mixture D to obtain a mixture E; adding the mixture B into the mixture E, carrying out ultraviolet and electron beam irradiation, adding effective microorganisms and azotobacter to obtain a fertilizer, and putting the fertilizer into a granulator; and drying and cooling. The rice fertilizer can effectively enhance the rice yield.

Description

technical field [0001] The invention relates to a preparation method of rice fertilizer. Background technique [0002] The protection of the ecological environment is particularly urgent in China. The long-term application of chemical fertilizers has led to serious negative problems such as soil structure damage, water pollution, reduced fertilizer use efficiency, and reduced quality of agricultural products. Nano-carbon is an insulator, but it can become a "superconductor" when exposed to water, so it is called "superconducting" fertilizer. After the nano-activated synergistic fertilizer enters the soil, it can greatly reduce the resistance of the soil colloid and solution, and become a conductive fertilizer. Its EC value is 30% to 50% lower than that of ordinary fertilizers, so it can save 30% to 50% of fertilizer. %Effect. It can mobilize macronutrients (nitrogen, phosphorus, potassium), secondary nutrients (calcium, magnesium, sulfur, and silicon) and trace elements (i...
