Technical model of “ivestock-fertilizer-grass” system

The development of stockbreeding greatly enriched livestock product markets,and povided scientific approaches for to be affluent.Meanwhile,it also heavily polluted most part of rural areas,rivers and lakes,which made against human beings health and sustainabe development of stockbreeding.In this paper,based on the analysis of technical model of“livestock-fertilizer-grass” system in the Sino-Dutch Dairy Demonstration Project, the effective way of pollution control for raising livestock was pointed out, which included comprehensive utilization of manure, keeping planting-raising in balance and realization of ecological dairy farm.The basis,technical flow and advantages of this systen were also introduced.It can reduce the discharge of sewage,save water use,save labors and time,and also make the dejection as a resource,which improve its economic benefits.
