A Calculating Method of Farm Machinery Supersedure Effect

农机作业替代人畜力作业的替代效益 ,目前多按单位面积 (公顷 )来计算。本文中提出了按单位劳动力计算的方法 。

The effect of substitution of farm machinery operation for laboure and live stock operation is generally calculated in terms of per unitary area(hm\+2). In this paper a calculating method of supersedure effect is advanced in terms of per unitary labour and according to different kinds of farm machinery management. The equations to calculate the critical values which can effect the substitution parameter are developed.
