田间机械化作业项目选择的量化模型及应用

Mathematical Model and Application in Selecting Fieldwork Items of Farm Mechanization

田间作业能否采用机械化进行，主要取决于机械化作业所产生的综合经济效益．若产出大于投入，则该项田间作业使用机械化有利，否则就不宜采用机械化．本文介绍了量化机械化作业经济效益的数学模型及它在农业生产中的实际应用．

Whether a fieldwork can be operated by far'm mechanization or not is mainly decided by the comprehensive economic effects of the fieldwork.If the output is larger than the input,the fieldwork can be completed by farm machine.In this paper,the authors introduced a mathematical model of evaluating the economic effeCt of the mechanized fieldwork and its application in Agriculture.
