Water-retaining drought-resisting long-acting slow-release compound fertilizer

Abstract

The invention relates to the compound fertilizer field, and particularly relates to a water-retaining drought-resisting long-acting slow-release compound fertilizer. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of a 1250-2000 mesh diatomite, 18-20 parts of ammonium hydrogen carbonate, 12-15 parts of potassium dihydrogen phosphate, 8-10 parts of calcium phosphate, 2-4 parts of ammonium molybdate, 10-12 parts of turfy soil, 1-2 parts of sodium selenite, 4-6 parts of a bamboo charcoal powder, 6-8 parts of tea residues, 1-3 parts of Chinese wolfberry leaf, 2-3 parts of an artemisia apiacea juice, 12-13 parts of wheat bran, 15-18 parts of feces of livestock and poultry, 2-4 parts of an enteromorpha prolifera powder, 4-5 parts of poloxamer, 1-2 parts of diclosulam, 4-6 parts of polyether amine D230, 10-12 parts of a waterborne acrylic emulsion, 1-2 parts of N-hydroxymethyl acrylamide, 2-4 parts of zinc gluconate, 6-8 parts of table vinegar, and 4-5 parts of an auxiliary agent. The compound fertilizer is wide in raw material sources and abundant in nutrients, allows double coating to be formed on the nutrients by using diatomite and a coating agent in the production process, allows the nutrients to be not easily lost, has more lasting fertilizer efficiency, has certain water-retaining drought-resisting abilities, can improve the crop yield and quality, and increases planting benefits.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a long-acting slow-release compound fertilizer for water retention and drought resistance. 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 fe...

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
