摘要
为综合评价植保机械的适用性,从技术指标、经济指标、作业条件指标3方面建立植保机械评价指标体系,利用层次分析法,对专家调查表进行汇总计算,采用专家判断矩阵加权几何平均法,确定各评价指标的权重。同时采用试验测评法、跟踪测评法和用户调查测评法交叉组合的方式获取3级指标分值,再通过分析计算,得到各级指标分值,从而构建植保机械适用性综合评价指标体系。最后对自走式喷杆喷雾机进行判定评分,从而得出单项指标评价和综合指标评价结果。建立植保机械适用性综合评价指标体系,为植保机械的推广应用提供了科学依据,同时对植保机械技术性能、作业质量等的优化提升具有指导意义。
In order to comprehensively evaluate the applicability of plant protection machinery, this paper established the evaluation index system from three aspects：technical index, economic index and operation condition index, used analytic hierarchy process to calculate the results of the expert questionnaires based on the structure model of the evaluation system, and determined the weights of each evaluation index by using judgment matrix and weighted geometric average method. And then it obtained the scores of the third level indicators by the method of test, as well as survey and evaluation of users, and then got the index scores of all levels through analysis and calculation. Finally the comprehensive evaluation index system for the applicability of plant protection machinery was built. This paper evaluated the self- propelled boom sprayer for example, and obtained the conclusions of the single index evaluation and the comprehensive evaluation. This can provide scientific basis for popularization and application of plant protection machinery by the comprehensive evaluation system, at the same time, it has guiding significance to the optimization and promotion of mechanical performance and operations quality of plant protection machinery.
