Abstract

The invention relates to a fertilizer. In order to reduce the fertilizer loss and increase the utilization ratio of nutrients in the fertilizer, the invention provides an organic and inorganic compound fertilizer containing organic mineral and inorganic mineral. A preparation method of the compound fertilizer comprises the following steps of: uniformly mixing 17-18% of kieselguhr mineral powder, 17-18% of humic acid mineral powder and 23-24% of organic fertilizer, then adding 0.5% of microbial compound agent for nitrogen fixation, phosphorus releasing and potassium releasing, and fermenting to prepare a biological organic fertilizer; uniformly mixing the biological organic fertilizer with 30% of N, P and K inorganic fertilizer, then adding 9-10% of gypsum powder as a binding agent, granulating by squeezing, sieving, and drying in the air to obtain the organic and inorganic compound fertilizer D. Secondary and trace elements accounting for 0.5-2.5% of organic and inorganic compound fertilizer D by weight are added before the gypsum powder is added. The organic and inorganic compound fertilizer can increase the crop yield by more than 15-25%, improve the utilization ratio of the fertilizer to more than 60%, realize the only one application time of the base fertilizer for first crop, and reduce the labor intensity and the fertilizer application cost.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a multi-formula organic-inorganic compound fertilizer containing organic and inorganic minerals, referred to as SV organic-inorganic compound fertilizer. This fertilizer is mainly used in calcareous soil in northern China. Background technique [0002] The current organic-inorganic compound fertilizers are mainly composed of nitrogen, phosphorus, potassium fertilizers and livestock and poultry manure, and the slow-release effect and special effect of fertilizers have not been fully exerted. The humic acid-type organic-inorganic compound fertilizers currently on the market are simply compounded with weathered coal humic acid and chemical fertilizers. Although they have played some role in supplementing soil organic matter, the effect is poor because the humic acid has not been activated. In addition, both coated slow-release fertilizers and chemical slow-release fertilizers have a certain impact o...
