HR401-M型绿肥还田机还田效果适用性研究

Research on the applicability of HR401-M green manure returning machine

为评价HR401-M型茶园绿肥还田机还田效果适用性情况,在恩施市高新开发区农科院茶园基地进行基于油菜的绿肥还田效果试验,结果表明HR401-M型绿肥还田机在试验地的粉碎长度合格率为94.7%,残茬高度为40.7mm,抛撒均匀度为90.9%;运用功效系数法和层次分析法计算适用性评价指标的单项分值及权重值,得出绿肥还田机在试验地还田效果适用度为74.95。通过计算适用度数值大小来评判绿肥还田机还田效果的地区适用性程度,可为同类农机具的地区选择提供理论参考。

In order to evaluate the applicability of returning effect of HR401-M green manure returning machine, the green manure returning effect test was carried out in the tea garden base of Enshi Autonomous Prefecture Academy of Agricultural,which located in high-tech development zone. The results showed that HR401-M green manure returning machine had a qualified rate of 94.7% in crushing length, a height of 40.7 mm in stubble and a uniformity of 90.9% in spreading. The single score and weight value of the suitability evaluation index were calculated by using the efficiency coefficient method and analytic hierarchy process, the applicability of the green manure returning machine to the experimental land was calculated to be 74.95. By calculating the value of applicability, the applicability degree of the green manure returning machine to farmland is evaluated, which can provide a theoretical reference for the regional selection of similar agricultural machinery.
