Abstract
The invention relates to the field of a compound fertilizer, and particularly relates to the compound fertilizer provided with a longan shell modified coating agent. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of diatomite of which the size is 1250-2000 meshes, 20-22 parts of mono-ammonium phosphate, 15-18 parts of potassium chloride, 6-8 parts of glucose, 10-12 parts of humic acid, 15-18 parts of plant ash, 18-20 parts of calcium magnesium phosphate fertilizers, 14-16 parts of urea, 2-3 parts of oleander leaves, 4-5 parts of crofton weed stem leaves, 10-12 parts of livestock excrements, 2-3 parts of longan shell micro-powder, 12-14 parts of mushroom scraps, 2-3 parts of ulothrix micro-powder, 3-5 parts of brown seaweed polysaccharide, 1-2 parts of nanometer carbon, 6-8 parts of methyl acrylate, 0.1-0.2 part of potassium peroxide, 1-2 parts of Tween 80, 2-4 parts of medical stone powder, 6-8 parts of polymeric ferric silicate sulfate and 4-5 parts of an additive. The compound fertilizer disclosed by the invention is abundant in raw material varieties and various in nutrients; due to utilization of the diatomite and a slow-release coating agent which contains the longan shell micro-powder, the nutrients can be dually coated, the fertilizer efficiency lasts quite long, and the compound fertilizer can provide the nutriments needed by the overall growth of common crops just after being applied once, so the compound fertilizer is a novel, green and high-efficiency compound fertilizer which can be used for remarkably improving the yield and quality of the crops and improving the economic efficiency.
Description
technical field [0001] The invention relates to the field of compound fertilizers, in particular to a compound fertilizer of longan shell modified coating agent. 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. However, the exis...
