Abstract

The invention discloses a preparation method of slow release compound fertilizer for improving the rice planting soil quality. The method comprises the following steps of after smashing sunflower seedmeal and fishbone dust, adding turfy soil for stirring to obtain a pre-prepared material; mixing ammonium chloride, concentrated superphosphate, potassium chloride, potassium nitrate, calcium humate,magnesium humate, ammonium molybdate, zinc humate, diaminoferric xanthohumate, coconut shell charcoal, zeolite powder and vermiculite powder, adding water, uniformly stirring, adding the pre-preparedmaterial and a chitosan compound for uniformly stirring, drying, and pelletizing to obtain the slow release compound fertilizer for improving the rice planting soil quality. The chitosan compound isprepared by adopting the following processes of uniformly mixing chitosan and ethanol water, adding glutaraldehyde, stirring at room temperature, removing residual glutaraldehyde, distilling to removethe ethanol water, adding the chitosan for carrying out homogeneization treatment, and obtaining the chitosan compound. The fertilizer obtained through the preparation method provided by the invention is comprehensive in nutrition, and is beneficial to improving the organic content in soil, optimizing a soil aggregate structure, and inhibiting harmful germ reproduction, so that the rice growth status is exuberant, and the rice quality is high.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a preparation method of a slow-release compound fertilizer for improving rice planting soil quality. Background technique [0002] Rice originates in tropical Asia. After being widely planted in China, it gradually spread to all parts of the world. 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] At present, in the process of rice planting, a large amount of chemical fertilizers are applied, and long-term use will destroy the soil aggregate structure, easily cause soil compaction, soil hardening, and cause pesticide resistance of pests, thereby affecting the growth of...
