Description
Technical field
The present invention relates to a kind of organic and inorganic fertilizer special for vegetable material technical field more particularly to a kind of environmental protection of organic and inorganic
The preparation method of environmental pollution free vegetable special fertilizer material.
Background technique
Currently, China's organic-inorganic complex fertilizer majority makees organic matter material using feces of livestock and poultry, using fermentation process into
Row processing, this processing mode has obvious effects on the germs such as living body roundworm egg and Escherichia coli, but to heavy metal cadmium, lead,
The noxious materials such as arsenic, chromium and antibiotic treatment effect are limited, more than the 800 tons of quinolone drugs that China produces every year, only this
Class antibiotic just has half to be used for aquaculture, and the organic-inorganic complex fertilizer produced with such feces of livestock and poultry is by a huge sum of money
Belong to the serious pollution with antibiotic, and the influence can have an effect to advanced bio by food chain, to destroy entire raw
The balance of state system, poses a threat to human health, and the poultry abuse of antibiotic causes zoonosis to increase, in addition, production
Process is to guarantee material granulating effect, needs to be added a large amount of clay as adhesive, be added a large amount of steam and water as at
Amount of liquid phase needed for grain, so that the organic matter and nitrogen of fertilizer, phosphorus, potassium nutrition ratio can be only sustained at lower degree, product moisture contains
Amount is high, and the easy dusting of resting period long grain influences mechanical application.
Summary of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of organic and inorganic environmental protection and public nuisance free fertilizer special for vegetable is provided
The preparation method of material, the secondary fermentation process of use have the characteristics that ferment effect is good and high-efficient, which can not only provide
Organic matter and inorganic elements are also rich in middle microelement, reach improvement soil, improve fertilizer efficiency, make crop yield, and article is made in raising
The effect of matter, but also it is avoided that pollution and the harm to the mankind brought by heavy metal and antibiotic noxious material.
It is another object of the present invention to improve material granulating rate using secondary granulation technology, system drying load, section are reduced
It can lower consumption, solve the problems, such as that organic fertilizer granulating is difficult, not need that the clay for promoting granulating is separately added and supplements a large amount of liquid phases to steam
There is nutrient content height, Shui to divide Han Liang≤2.5%, be far below moisture content for vapour or water, prevented from caking and dusting, manufactured product
≤ 12% national standard, the advantage that granule strength is good, at low cost, long time stored particle will not occur and become mildewed and dusting
Problem is suitable for mechanical application.
