Abstract

The invention belongs to the technical field of fertilizers, and particularly relates to a calcium-containing water-soluble compound fertilizer and a preparation process thereof. A solid fermentation culture medium is prepared by using bean pulps are used as a major ingredient and being supplemented by potatoes, Chinese yam, tea seed cake, molasses and sodium chloride; plant active peptides are prepared by a method of combined step-by-step fermentation on various bacteria such as lactobacillus fermenti, bacillus subtilis and a subtilis subspecies of the bacillus; polypeptide calcium powder prepared by the prepared active peptides and a calcium-containing compound through chelation has good water solubility; after the polypeptide calcium powder and a large number of element raw materials are mixed and pelleted, the calcium-containing water-soluble compound fertilizer is prepared; nutritional ingredients of the compound fertilizer difficultly run off and are fixed by soil; the fertilizer utilization rate is high; the crop yield and income increase and the crop quality improvement are facilitated. In addition, the calcium-containing water-soluble compound fertilizer provided by the invention does not contain preservatives; mildew does not easily occur; the storage time is long; meanwhile, soil-borne diseases such as root rot, powdery mildew and gray mold can be effectively prevented and controlled; the incidence rate of the soil-borne diseases is reduced.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a calcium-containing water-soluble compound fertilizer and a preparation process thereof. Background technique [0002] Compound fertilizer refers to chemical fertilizers containing two or more nutrient elements. It has the advantages of high nutrient content, less auxiliary components and good physical properties. It is very important for balanced fertilization, improving fertilizer utilization, and promoting high and stable crop yields. effect. Conventional compound fertilizers have slightly poor water solubility and are generally used as base fertilizers to supplement the three elements of nitrogen, phosphorus, and potassium required for crop growth. However, the growth and development of crops not only need nitrogen, phosphorus and potassium, but also trace elements. Although crops do not have as much demand for secondary elements as nitrogen, phosphorus, an...
