Problems solved by technology

If the nutrient content of the applied fertilizer is not complete or balanced, it will not be able to fully meet the nutrients needed for mango growth, which will easily lead to the occurrence of physiological diseases, and the general yield increase efficiency is low
At the same time, after fertilizer application, especially in the rainy areas in the south, the soluble inorganic fertilizer will dissolve quickly, which reduces the effect of fertilizer application on the one hand, causes waste of fertilizer, and pollutes surrounding water bodies

Abstract

The present invention provides a special controlled release fertilizer for mangoes and a preparation method for the fertilizer, and belongs to the technical field of fertilizers. The fertilizer comprises an outer wrapping layer and an inner fertilizer particle composed of a natural polymer coating material. The fertilizer particle is prepared by mixing the following components: monoammonium phosphate, calcium magnesium phosphate power, urea, potassium chloride, borax, humic acid, copper sulfate, zinc sulfate, magnesium sulfate, ferric nitrate, compound sodium nitrophenolate, polyglutamic acid, and an adhesive. The fertilizer contains abundant and comprehensive nutrient components, can satisfy the requirement on various nutrients in a normal growth process of mangoes, and the fertilizer enhances the disease resistance and cold resistance of the mangoes, and improves the fruit quality; the fertilizer has a good controlled release effect, effectively reduces fertilizer nutrient loss, and increases the fertilizer utilization; and the selected natural polymer coating material has an excellent biodegradation performance, causes no ecological pollution, and has an environmental-friendly effect.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special controlled-release fertilizer for mangoes and a preparation method thereof. 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, raw material so...
