耕作部件天然草地作业适用性综合评价模型研究
Comprehensive evaluation model for the operational suitability of tillage components applied on natural grassland
摘要
Abstract
In view of the limitations of the current tillage components in natural grassland operation and the lack of comprehensive evaluation method for its applicability in grassland operations and the evaluation system for the operation effect of special grassland improvement tillage components,the coefficient of variation method and linear weighting method were adopted to study the weight of each evaluation index.A comprehensive evaluation model was constructed for the applicability of natural grassland operation of tillage components,and then field tests were conducted to verify the comprehensive evaluation model.The results showed that:The comprehensive evaluation model proposed in this study was constructed based on three indexes,e.g.,traction force,surface turning rate and soil disturbance coefficient,which could effectively evaluate the applicability of tillage components in natural grassland operation.The operational effects of different tillage components evaluated by the new model in this study were consistent with the results of existing research,which confirmed the feasibility of the comprehensive evaluation model.In conclusion,this study provided a more convenient method for the comprehensive evaluation of the applicability of tillage components in natural grassland operation.关键词
