Active controlled-release composite fertilizer containing wine cellar mud

Abstract

The invention relates to the field of composite fertilizers and specifically relates to an active controlled-release composite fertilizer containing wine cellar mud. The fertilizer is prepared from the following materials in parts by weight: 10-15 parts of 1250-2000-mesh diatomite, 12-14 parts of feces of livestock and poultry, 8-10 parts of bryophyte, 6-8 parts of plant ashes, 2-3 parts of bamboo vinegar, 5-8 parts of waste coffee grounds, 3-5 parts of zinc carbonate, 10-12 parts of calcium hydrophosphate, 7-8 parts of saw dust, 10-12 parts of fish pond sludge, 2-4 parts of active carbon, 5-8 parts of tea stems, 8-10 parts of wine cellar mud, 2-4 parts of angled bittersweet stems, 4-6 parts of calcium superphosphate, 1-3 parts of lemon peel, 0.1-0.2 part of nano zinc sulfide, 6-8 parts of carboxymethyl chitosan, 1-3 parts of epoxy soybean oil, 4-5 parts of glycerol, 12-15 parts of polyvinyl alcohol, 1-2 parts of lauryl sodium sulfate and 4-5 parts of auxiliaries. The composite fertilizer disclosed by the invention is wide in formula source, contains various materials which are cheap, easily available, and rich in active biomass, can effectively improve soil environment, can promote crop growth, utilizes diatomite and a controlled-release film-coating agent to form dual coating for nutrients, is more lasting in fertilizer effect, and obviously improves crop yield and quality.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to an active slow-release compound fertilizer containing wine cellar mud. 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
