Abstract

The invention relates to the field of compound fertilizers and in particular relates to a double slow-release compound fertilizer containing brucea javanica oil. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of 1250-2000-mesh kieselguhr, 8-9 parts of bagasse, 10-12 parts of humic acid, 4-6 parts of zinc citrate, 18-20 parts of potassium carbonate, 20-22 parts of carbamide, 6-8 parts of trichosanthes peel, 4-6 parts of monosodium glutamate residue, 3-5 parts of broken cottonseeds, 5-6 parts of grass meal, 8-9 parts of turf, 1-2 parts of pericarpium granati, 10-12 parts of waste yeast mud, 8-10 parts of pig manure, 10-12 parts of polyvinyl alcohol, 1-2 parts of sodium diethylhexyl sulfosuccinate, 3-5 parts of carboxymethyl cellulose sodium, 1-2 parts of brucea javanica oil, 2-4 parts of medical stone powder, 6-8 parts of polymeric ferric silicate sulfate and 4-5 parts of additives. The compound fertilizer is diversified; double coatings are formed on nutrients by using the kieselguhr and slow-release film-coating agents containing the brucea javanica oil, so that the nutrients are not easy to lose; the compound fertilizer as a novel green and efficient compound fertilizer is relatively long in fertilizer efficiency, high in utilization rate of fertilizer, free of damage to the ecological environment of the soil and capable of remarkably improving the yield and quality of crops and improving the economic benefit in a practical application.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a double slow-release compound fertilizer containing javanica javanica oil. 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. How...
