High-quality strawberry planting dedicated slow-release compound fertilizer

Abstract

The invention relates to the compound fertilizer field, and particularly relates to a high-quality strawberry planting dedicated 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, 4-5 parts of borax, 2-3 parts of ammonium molybdate heptahydrate, 10-12 parts of sodium humate, 20-25 parts of urea, 18-22 parts of potassium nitrate, 25-28 parts of organic compost, 2-4 parts of fish meal, 1-3 parts of sesame leaves, 8-10 parts of alfalfa meal, 15-18 parts of corn distiller grains, 2-4 parts of brine, 8-10 parts of an erythromycin fungi residue, 1-2 parts of an EM microbial agent, 4-6 parts of a fern root residue, 1-3 parts of nano silver, 1-2 parts of a semen ginkgo powder, 4-6 parts of 1,6-hexanediol diacrylate, 10-12 parts of an acrylic resin dispersion liquid, 1-2 parts of isocyanate, 1-2 parts of calcium stearoyl lactate, 2-4 parts of zinc gluconate, 6-8 parts of table vinegar, and 4-5 parts of an auxiliary agent. The compound fertilizer has multiple nutrients, is low in production cost and good in slow-release effect, allows double coating to be formed on the nutrients by utilizing diatomite and a coating agent in the process, also contains various trace elements, has no toxicity and no pollution, and is excellent in quality of planted strawberry and obvious in yield and income increasing effects.

Description

technical field [0001] The invention relates to the field of compound fertilizers, in particular to a special slow-release compound fertilizer for high-quality strawberry planting. 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....

AI Technical Summary

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
