Special slow-release compound fertilizer for mango and preparation method thereof

Abstract

The invention provides a special slow-release compound fertilizer for mango and a preparation method thereof, belonging to the technical field of fertilizer. The fertilizer comprises inner fertilizer particles and an outer wrapping layer composed of a natural polymer coating material, wherein the inner fertilizer particles are prepared from the following components through mixing: monoammonium phosphate, calcium magnesium phosphorus powder, urea, an organic ferment material, potassium chloride, borax, copper sulphate, zinc sulfate, ferric nitrate, compound sodium nitrophenolate, polyglutamic acid and an adhesive. The special slow-release compound fertilizer contains abundant and comprehensive nutritional components, can meet demands of mango for a variety of nutrients in the process of normal growth, improves disease resistance, cold resistance and fruit quality of mango, has good slow release effect, effectively reduces loss of nutrients in the fertilizer and has an increased utilization rate; moreover, the natural polymer coating material used in the invention has good biodegradability, does not pose ecological pollution and is friendly to the environment.

Description

technical field

[0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special slow-release compound fertilizer for mangoes and a preparation method of the fertilizer. Background technique

[0002] Mango is one of the famous tropical fruits. Mango fruit contains sugar, protein, and crude fiber. The precursor carotene of vitamin A contained in mango is particularly high, which is rare among all fruits. Secondly, the vitamin C content is not low. Minerals, proteins, fats, sugars, etc. are also its main nutrients. It can be used to make fruit juice, jam, canned food, pickles, hot and sour pickles, mango milk powder, candied fruit, etc.

[0003] How to increase the yield of mango is one of the key factors to improve the economic benefits of mango, and fertilization is one of the essential measures to improve the yield of mango. Due to the differences in the soil, mango growth stages, fertilizer requirements, fertilizer varieties, ra...
