一水田动力机组最佳工况是指:拖拉机或机耕船等动力机械,在水田作业时配以相应的农具,完成同一作业量所消耗能量最少的工作状况。用水田牵引试验得出的牵引特性指标,来评价水田动力机械的动力性能与经济性能是不够确切的。单视追求最大牵引功率和最 The best condition for a paddy field power unit is that the power machinery such as a tractor or a tractor is matched with the corresponding farm tools when working in the paddy field to complete the working condition with the least energy consumed by the same workload. It is not clear enough to evaluate the dynamic and economic performance of paddy field power machinery based on the traction characteristics index obtained from the paddy field traction test. Single pursuit of maximum traction power and the most
