Description
Technical field
The present invention relates to a kind of method of organic waste recycling, in particular to a kind of organic biofertilizer production sides
Method.
Background technique
China human mortality is numerous, and for the needs for meeting people's daily life, grain-production occupies an important position.With industry
Production, town and country construction, the non-agricultural-transformation process in the quickening arable land of energy transport development, especially urbanization of villages and process of industrialization
Accelerate, carrys out adding fuel to the flames for occurred development zone craze, Real estate craze etc. in recent years in addition, the cultivated area in China is made to contract rapidly
Subtract.
To allow grain yield increase to bring more land under cultivation or making the output increased of unit area.But the arable land face in China
Product is smaller, and it is smaller to continue widened potentiality.This just determines that Grain in China volume increase to be made can only increase the yield per unit area.Fertilising
Especially application chemical fertilizer is the important method that per unit area yield can be improved.It is counted according to FAO (Food and Agriculture Organization of the United Nation) (FAO), chemical fertilizer is to crops
Portion is 40%~60% in the effect of volume increase.But chemical fertilizer is largely applied while producing serious harm, such as soil
Hardened, fertility decline, or even threaten the health of the mankind.
In order to solve problem above, people begin one's study organic biofertilizer, and organic biofertilizer is composite microbe fertilizer
