Abstract: In this study,the aim was to explore the rapid and efficient technology on transforming discharge of livestock and poultry into fertilizer. Firstly,a certain rate of water in cow dung and chicken manure evaporated by coverage of greenhouse film,the usage of solar energy and ground handling. Secondly,biological agents was added into it,after the granule was formed by drum granulator,accumulation of fermentation was made. The results showed that the pH value is 7.5 stably six days later,the rate of C/N decreased from 19 to 11 with stabilization,seed germination index reached 98 %. In conclusion,it reaches the compost maturity indexes,also lays the foundation for the scale production of organic fertilizer.
