Multi-variety compound fertilizer and biomass granular fertilizer production method thereof

Abstract

The invention provides a multi-variety compound fertilizer, which is prepared by mixing the following raw material fertilizers by weight: 500-520 parts of urea, 85-90 parts of Ammonium dihydrogen phosphate, 150-170 parts of potassium chloride, 70-80 parts of calcium magnesium phosphate fertilizer, 50-60 parts of straw tower powder, 2-3 parts of composite or single bacterial fertilizer powder, and 50-60 parts of humic acid powder. The steps for preparing a biomass granular fertilizer by using the multi-variety compound fertilizer comprise: 1, preparing materials, wherein the materials comprise the raw material fertilizers and plant starch or industrial paste; 2, mixing; 3, preparing a biomass adsorption material; 4, adding an excess amount water to dissolve soluble substances and impregnate water-insoluble substances; 5, adding a sufficient amount of an adsorption particle material to completely suck the solution; and 6, drying, carrying out grain rolling, inspecting, weighing, bagging, and sealing. According to the present invention, the good synergism of the use of the multi-variety compound fertilizer is provided compared with the use of the single-variety fertilizer, the application amounts of the fertilizer and the pesticide are reduced, the fertilizer utilization rate is improved, the non-point source pollution is reduced, the soil structure is improved, the crop yield is increased, the number of the fertilizer application is reduced, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to a compound fertilizer and a production method of granular fertilizer thereof, in particular to compound fertilizer mixed with different fertilizer varieties and a production method of granular fertilizer using sponge-structured biological material as the adsorption main body and particle skeleton. Background technique [0002] There are many types of fertilizers used in agriculture for crops, fruit trees, and bamboo and wood, including single fertilizers and compound fertilizers, chemical fertilizers and bacterial fertilizers, organic fertilizers and inorganic fertilizers, mineral fertilizers and medicinal fertilizers, etc. The so-called mineral fertilizers such as South Korea The straw tower (ZETA) brand natural mineral trace element fertilizer produced by Ximenkangtosi Co., Ltd. The so-called medicinal fertilizer refers to the fertilizer mixed with insecticidal and antibacterial substances and common fertilizers. There are ma...
