摘　　要：田块大小对农业机械的效率发挥至关重要,合理规划田块有利于提高农业机械利用率。为提高甘蔗机械化作业效率,提出以纯作业时间利用效率对甘蔗作业机组的效率进行衡量,并对甘蔗机械在田块内的作业进行试验和仿真,提出甘蔗播种机组和收割机组适宜作业的地块条件;同时,运用Extendsim软件建立收获运输系统模型,分析满足高效率的地块条件对收获运输系统的影响,并对运输系统中转运车数量及收割机组作业等待时间进行仿真。研究结果表明:不同作业幅宽和载种量的播种机组有不同的田块规划要求,为实现收割机组作业效率达到0.8,地块规划长度尽可能在1200m以上;规划地块下田间转运车辆是影响收割机持续作业的主要因素,增加田间转运车数量能减少收割机等待时间和甘蔗平均运输时间。研究结果可为机械化条件下甘蔗土地种植规划和管理提供参考。The size of field plays an important role in the efficiency of agricultural machinery.In order to improve the efficiency of sugarcane mechanization operation,the pure working time utilization efficiency was put forward to measure the efficiency of sugarcane operation unit,and the operation of sugarcane machinery in the field was tested and simulated,and the suitable plot conditions for sugarcane sowing unit and harvesting unit were put forward.The harvest transportation system model was established by using Extendsim software to analyze the influence of high-efficiency land conditions on the harvest transportation system,and the number of transfer vehicles in the transportation system and the operation waiting time of harvesting units were simulated.The results showed that the seeding units with different operating widths and seed loads had different field planning requirements.In order to achieve the operating efficiency of the harvesting units up to 0.8,the planned length of the plots should be over 1200m as far as possible.Interfield transport vehicles of planned plots are the main factors affecting the continuous operation of harvesters.Increasing the number of field transport vehicles can reduce the waiting time of harvesters and the average transport time of sugarcane.The research results can provide reference for sugarcane land planting planning and management under the condition of mechanization.
