Investigates about Peashrub resource Utilization and its Feed Exploits Processing at the Present Situation in Ningxia--Based on the Yanchi County

We did some investigated and Studied on the Peashrub resource Utilization at the Present Situation and its Feed Exploits Processing based on Yanchi prefecture,Ningxia province.The mainly ideas are about its spreads,utilization technologies,problems etc..The results are: Peashrub resource areas are 436,723 hectares in Ningxia.It is about 8.431% of the total areas.The natural shrub resource areas are 25,905 hectares.In the parts of them 410,818 hectares are man-planted during the short period,it is about 94.068%.Its characters are: areas are very large,spreads very wide,the quantity of biosphere stores is also very much,but the ratio of its young age is very high.The problems are: the ratio of exploit and utilize,the ratio of aging are very low.Over-grazed is also belongs the mainly problem.We gave some useful suggestion based on the present situation about its exploits in the end of this thesis.
