Abstract

The invention discloses a preparation method of a fertilizer specially used for paddy rice. The preparation method includes the following steps: 1) pyrolyzing bamboo powder at high temperature and adding urea with mixing, adding dipotassium phosphate to the mixture in an inert atmosphere, heating the mixture for activation, and cooling the mixture to room temperature; 2) adding collagen protein, soya bean protein and water to the mixture, heating and stirring the mixture, adding polyvinyl alcohol and potassium persulfate, uniformly mixing the components, regulating the pH value of the mixture to 6.4-6.8 and adjusting temperature, stirring and cooling the mixture, and spray-drying the mixture to prepare a material A; 3) uniformly mixing the material A with diammonium phosphate, potassium chloride, zinc sulfate, borax and nano-bentonite, feeding the mixture to a drum coating machine, increasing the temperature to preheat the mixture, spraying wintergreen oil on the mixture, continuously stirring the mixture, and discharging and air-drying the mixture to prepare a premix B; and 4) feeding the premix B to the drum coating machine, increasing the temperature to preheat the premix B, spraying molten paraffin on the premix B, continuously stirring the premix B, and discharging and drying the premix B to produce the fertilizer specially used for paddy rice.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a preparation method of special fertilizer for rice. Background technique [0002] my country is a large agricultural country. Chemical fertilizers and pesticides play a very important role in agricultural production. With the improvement of people's living standards and health awareness, people attach great importance to the safety of agricultural products, and the demand for pollution-free and green food is increasing year by year. . [0003] There are many types of fertilizers currently used for hybrid rice cultivation, among which the special fertilizer for hybrid rice mostly adopts NPK compound fertilizer available on the market, which is mainly composed of three inorganic elements N, P, and K, which can meet the growth of hybrid rice in a short time need. However, long-term use will damage the soil aggregate structure, easily cause soil compaction and soil hardening, t...
