Problems solved by technology

However, due to the water-soluble nature of chemical fertilizers, it is prone to deliquescence during transportation and storage, making it loose into powder or agglomerated into blocks, causing inconvenience to transportation and application.
In addition, during the process of placing chemical fertilizers, certain components contained in them will slowly chemically react with oxygen in the air, causing the loss of effective components and reducing the application efficiency.

Embodiment Construction

[0016] see figure 1 , the high-efficiency compound fertilizer is in the form of granules, and the granules are composed of a core body 1 and a coating 2, and the coating completely covers the core body. Nucleus can use granular inorganic fertilizers such as: diammonium phosphate, monoammonium phosphate, ammonium chloride, ammonium nitrate, ammonium sulfate, potassium sulfate, potassium chloride, urea and binary compound fertilizers or ternary compound fertilizers. The coating is BSFA biochemical fulvic acid organic fertilizer. BSFA biochemical fulvic acid is an excellent ingredient in humic acids. After it is applied to the soil, it can stimulate plant growth, improve the quality of crops, and combine trace elements to relieve pesticide poisoning. It is a green fertilizer with great development prospects. In addition, BSFA biochemical fulvic acid is non-toxic and harmless, and has a strong fragrance, which is easily accepted by users. Making it into a coating and using it t...

Abstract

The present invention relates to a kind of high-efficiency composite chemical fertilizer and its preparation, belongs to the field of fertilizer mixture and aims at solving the problems of chemical fertilizer, which is easy to deliquesce, harden and decompose and has fertilizer effect to be raised. The composite chemical fertilizer consists of a core of inorganic chemical fertilizer grain and a coating of BAFA biochemical fulvia acid. The protective coating can prevent chemical fertilizer from deliquescing, hardening and decomposing and the biochemical fulvia acid can stimulate the growth of plant root system and raise the fertilizer effect of inorganic chemical fertilizer by 3-20%.

Description

technical field [0001] The invention relates to an improved chemical fertilizer and a preparation method thereof, in particular to a compound chemical fertilizer of biochemical organic fertilizer and inorganic fertilizer, and belongs to the technical field of fertilizer mixture. Background technique [0002] Fertilizer is an important substance that provides nutrients necessary for plant growth, improves soil conditions, and increases crop yields. Since the 1950s, with the continuous growth of the population, the demand for crops has also increased. It has been difficult to maintain the demand of the soil only by traditional organic fertilizers, and more and more chemical fertilizers have been put into use. According to statistics, from the 1950s to the 1990s, the use of chemical fertilizers in the world increased by about ten times, and the grain output increased by about three times. Taking my country as an example, our country is a large agricultural country, with 7% of ...
