Abstract

The invention discloses a preparation method of a compound slow release fertilizer used for lotus root for improving soil, comprising the following steps: blending whey protein, epoxidized soybean oiland water, performing freeze drying, adding microcrystalline cellulose and a tartaric acid aqueous solution and stirring, and performing freeze drying to obtain a prefabricated material; smashing pigmanure, deodorizing, adding corncob powder, straw powder, zeolite powder and coconut shell charcoal and uniformly mixing, adding water, and adding EM microbial agent for anaerobic fermentation to obtain a fermented material; smashing ammonium sulfate, seabird excrement, plant ash, ammonium-ferrum phosphate, calcium sulfate, zinc humate and mica powder, uniformly mixing, adding the fermented material to uniformly stirring under a stirring state, sequentially adding the prefabricated material and hydroxyethyl cellulose for pelleting, and drying to obtain the compound slow release fertilizer used for lotus root for improving soil. The fertilizer prepared by the invention not only can meet the requirement of the lotus root for nutrient substances, and remarkably increase the output and quality of the lotus root, but also can improve the soil structure and water holding capability, ensure the growth of the lotus root and increase the output.

Description

technical field [0001] The invention relates to the technical field of lotus root planting, in particular to a method for preparing a compound slow-release fertilizer for lotus root for soil improvement. Background technique [0002] Lotus root is one of the common cultivated plants in my country. Lotus root has high nutritional value and is rich in various nutrients and vitamins needed by the human body. According to statistics, the planting area of ​​lotus root in my country has expanded rapidly in recent years. [0003] The lotus root requires a large amount of fertilizer, and the fertilization of the lotus root requires proper coordination of various nutrient elements to avoid single application of chemical fertilizers. Single application of chemical fertilizers not only causes serious soil degradation and compaction problems, but also seriously restricts the improvement of lotus root yield and quality. Contents of the invention [0004] Based on the technical problems...
