Problems solved by technology

In this way, no matter how excellent the strains are in terms of nitrogen fixation, phosphorus dissolving, and potassium dissolving functions, no matter how outstanding the strains are in improving soil quality, if they cannot solve the problem of high osmotic pressure killing, they will not be able to solve the problem of chemical fertilizers. If the problem of coexistence in the body, it cannot enter the market as a mainstream fertilizer, and it is impossible for farmers to use it on a large scale

Abstract

The invention discloses a method for preparing an organic-inorganic potassium-calcium-silicon compound fertilizer. The organic-inorganic compound fertilizer is prepared by mixing and blending the following raw material components in part by weight: 1 to 90 parts of potassium-calcium-sulfur compound fertilizer produced by compoundly roasting alkali-making white mud and potassium ores and 1 to 90 parts of biological organic fertilizer. The double benefits of industrial solid waste recycling and a novel potassium fertilizer are achieved; the whole production process accords with an environment-friendly idea, and solid and liquid wastes are not discharged; and the fertilizer can increase the yield of crops, improve product quality and regulate the acidity and alkalinity of soil through field experiments of the crops such as rice, sugarcane, cassava, sweet corn and the like.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a preparation method of an organic-inorganic potassium-calcium-silicon compound fertilizer. Background technique [0002] Microbial organic fertilizer is a microbial organic fertilizer processed from organic solid waste (including organic waste, straw, livestock and poultry manure, cake, agricultural and fishery by-products and solid waste from food processing) through microbial fermentation, deodorization and complete decomposition. The characteristic of microbial organic fertilizer is that the ecological organic fertilizer has complete nutrients, which can improve the soil and improve the soil compaction caused by the use of chemical fertilizers. Improve soil physical and chemical properties, enhance soil water retention, fertilizer retention, and fertilizer supply capabilities. The beneficial microorganisms in the microbial organic fertilizer enter the soil and form a symbiotic multip...
