Abstract

The invention relates to the field of compound fertilizers, in particular to a water-retaining and yield-increasing slow release compound fertilizer. The fertilizer is prepared from the following raw materials by weight part: 10-15 of 1250-2000 mesh diatomite, 5-6 of calcium chloride, 4-5 of sodium borate, 18-20 of potassium citrate, 23-25 of urea, 20-25 of diammonium phosphate, 15-18 of a crop leftover fermentation broth, 4-5 of livestock blood plasma, 10-12 of vinegar residue, 1-3 of egg shell powder, 2-3 of Galium aparine, 1-2 of szechwan chinaberry fruit powder, 2-3 of soybean peptide powder, 6-8 of earthworm feces, 4-5 of dry corn ear, 1-2 of sodium methyl parahydroxybenzoate, 10-12 of crosslinked polyvinylpyrrolidone, 3-4 of methyl methacrylate, 4-5 of butyl acrylate, 1-2 of sodium dodecylbenzene sulfonate, 0.1-0.2 of ammonium persulfate, 2-4 of medical stone powder, 6-8 of polymeric ferric silicate sulfate, and 4-5 of an assistant. The compound fertilizer provided by the invention has the characteristics of multielement nutrient, low cost, dual slow release coating, more lasting fertilizer efficiency, water-retaining and drought resistant ability, and no destruction of soil ecological environment, and is a novel green and efficient compound fertilizer, which can significantly enhance the crop yield and quality and increase economic benefits in practical application.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a water-retaining and yield-increasing slow-release compound fertilizer. Background technique [0002] In modern agricultural production, compound fertilizer can be seen everywhere. It has the advantages of high nutrient content, less auxiliary components, high fertilizer utilization rate, and convenient storage and application. It plays an important role in promoting high and stable crop yields. Slow-release compound fertilizer is an important category of compound fertilizers, and it is also the focus of research on the development of my country's chemical fertilizer industry. Its slow-release principle is to coat a thin layer of hydrophobic substances on the surface of fertilizer particles, so that the internal nutrients are slowly released to the In the soil, nutrients are continuously supplied to crops, which effectively improves the utilization rate of fertilizers. Howeve...
