A slow-release compound fertilizer containing garlic oil coating agent

Abstract

The invention relates to the field of compound fertilizers and specifically relates to a controlled-release compound fertilizer containing a garlic oil film-coating agent. The fertilizer is prepared from the following materials in parts by weight: 10-15 parts of 1250-2000-mesh diatomite, 10-12 parts of calcium chloride, 6-8 parts of sodium borate, 12-15 parts of potassium superphosphate, 18-20 parts of urea, 8-10 parts of ammonium triphosphate, 20-22 parts of potassium hydrogen phosphate, 1-2 parts of indole potassium butyrate, 5-8 parts of folium urticae stem powder, 5-6 parts of sweet potato skin, 1-3 parts of garlic oil, 2-4 parts of garlic skin, 10-12 parts of cow dung, 6-8 parts of duck manure, 4-5 parts of chestnut shells, 10-12 parts of styrene, 2-3 parts of methacrylic acid, 0.1-0.2 part of dicumyl peroxide, 6-8 parts of ethyl acetate, 2-4 parts of medical stone powder, 6-8 parts of iron polysilicate sulfate, and 4-5 parts of auxiliaries. The compound fertilizer disclosed by the invention is wide in source, polybasic in nutrient; on production process, diatomite and the film-coating agent containing the garlic oil are utilized to carry out dual coating on nutrients, so that excellent controlled release effect is achieved, fertilizer efficiency is more lasting, fertilizer utilization rate is improved, yield and quality of crops are improved, and planting benefits are increased.

Description

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

Problems solved by technology

However, the existing slow-release compound fertilizers still have certain shortcomings, mainly in that the nutrient ratio is relatively fixed, and it is difficult to meet the different needs of various soils and various crops; the slow-release effect is not satisfactory, and does not match the growth needs of crops , thereby reducing fertilizer efficiency, affecting crop growth, resulting in reduced production and income
