Composite organism slow release fertilizer product and producing method

Abstract

The present invention relates to a chemical fertilizer and a manufacturing method thereof, specifically to a composite biological slow-release fertilizer product and its manufacturing method. Said composite biological slow-release fertilizer product in accordance with the present invention comprises granular fertilizer cores and coatings packing outside of the fertilizer cores, wherein said fertilizer cores are grains formed by a mixture of ternary compound fertilizer and the slow-release components which are mixture of urea and humic acids. Said coatings comprises at least animal oil and fat, bone meal and bacillus components. By replacing steam for heat spraying granulation with urea and humic acids melting complexing liquor, the manufacturing method in accordance with the present invention resolves the problem of moisture exceeding standard in 'three (organics, inorganics and bilogies) in one' fertilizer production and achieves the goal of nitrogen slow-release. At the same time, by adopting animal oil and fat and bone meal which can provide food such as lipids to animalcules and are easy to degrade as bacillus preparation carrier, said method overcomes the problems that the mixing of bacillus preparation and other fertilizer components leads to bacterial agent pollution and bacterium poisoning phenomenna. The present invention provides a 'three (organics, inorganics and bilogies) in one' composite biological slow-release fertilizer product which exhibits quick results, slow results and long results integrally, and a manufacturing method thereof.

Description

technical field [0001] The invention relates to a chemical fertilizer and a production method thereof, in particular to a compound biological slow-release fertilizer product and a production method thereof. Background technique [0002] With the continuous development of agricultural production, traditional agriculture with high energy consumption, high pollution and low output will be replaced by ecological agriculture with high output, low consumption, high quality, high efficiency and sustainable development. To achieve this goal, we must first solve the current situation of low nutrient utilization of chemical fertilizers, poor degree of mechanized fertilization, and repeated irregular fertilization. To solve this problem, in addition to formulating balanced fertilization and improving the scientific level of fertilization, as far as the fertilizer itself is concerned, it is necessary to improve the fertilizer dosage form, develop a wide range of applications, high nutri...

Problems solved by technology

Above-mentioned first kind of method is quite different from the present invention

The coating materials used in the second method can be divided into two categories: polymer and sulfur coating, and inert material coating. Due to the poor solubility of polymer and sulfur coating, the coating layer does not contain water-soluble materials, resulting in fertilizer seepage. Poor yield, the release rate of nutrients is inconsistent with the law of fertilizer requirements of crops, and sometimes causes secondary pollution to the environment. The carriers coated with inert materials are mostly machinery oil and other substances. If used improperly, it is easy to cause secondary pollution to the environment. Pollution

[0003] In addition, fertilizer agglomeration, especially the agglomeration problem of ternary compound fertilizers, has seriously restricted the development of the compound fertilizer industry
