Problems solved by technology

[0003] (1) The influence of the production process: high-nutrient granular fertilizers, the bacteria addition process can be designed in the early material mixing stage, directly mixed with the rest of the materials for granulation, but high-temperature drying process is required after the granulation process, and the temperature is usually higher than 100 ℃, there is the problem of high-temperature loss of bacteria. After high-temperature drying, the survival rate of bacteria is usually less than 10%, and the inactivation is serious; the addition of bacteria can also be designed to cover the surface after the subsequent low-temperature cooling process of particle forming, but there is a problem of coating The amount of coverage is small, and the problem of easy powder removal affects product quality

Abstract

The invention relates to a fertilizer, in particular to a biological functional fertilizer with a core-shell isolation coating structure and a preparation method of the biological functional fertilizer. The biological functional fertilizer is granular, and comprises a core fertilizer; a coating layer which is formed on at least part of the outer surface of the core fertilizer, wherein the coating layer is composed of a first coating layer, a second coating layer and a surface coating layer which are arranged from inside to outside, the first coating layer is formed by mixing an organic material and xanthan gum according to the mass ratio of 1: (0.01-0.03), the second coating layer is formed by mixing a microbial agent, a functional additive and seaweed enzymatic hydrolysate according to the mass ratio of (2-5): (1-2): (3-5), and the surface coating layer is formed by mixing a powdery anti-blocking agent and an oily anti-blocking agent according to the mass ratio of (0.3-0.4): (0.2-0.3). The biological functional fertilizer is high in biological activity and excellent in functionality.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a biofunctional fertilizer with a core-shell isolation coating structure and a preparation method thereof. Background technique [0002] The dosage forms of biological fertilizers generally include three types: granule, powder and liquid. The production process of powder and liquid products is relatively simple. Under the premise of low nutrient content, the effective number of viable bacteria can be relatively high, but for granular fertilizers, especially high Granular fertilizers with nutrient content are limited by the production process and nutrient salt damage, and the effective number of viable bacteria is usually low; the details are as follows: [0003] (1) The influence of the production process: high-nutrient granular fertilizers, the bacteria addition process can be designed in the early material mixing stage, directly mixed with the rest of the materials for granulation, but high-temp...
