| Abstract: | This paper describes the amount,direction,effect and tendency of the power energy input from farming machinery manpower and animal power sources into Zhoupu model farm located in Guizhou Plateautl.It was shown that the energy input of machines,manpower,animal power and fuel are 30.8%,18.6%,0.2% and 50.2%,respectively;the energy input of industrial source is 4.3 times higher than that of biological source in the farm.The study also indicates that the highlevel mechanized system is less effective than semi-machanized system,so is the manual working system.The energy input pattern is to use further more animal power and less manpower. |
