现在稻麦收获主要是机械收割,联合收割机是稻麦收获的主要机械,因其购买价格较大,结构复杂,故正确操作使用,对延长其寿命,提高工作效率,减少作业损失,显得十分重要。1.联合收割机的正确操作使用一是正确选择割茬的高度。根据作物产量、高度、成熟度及时调整收割机的前进挡位、割幅和割茬高度,尽量减少长时间超负荷作业。二是合理选择作业速度。当作物成熟度较高,地面平坦,秸秆比较干燥、稀疏,杂草较少时,
Rice and wheat harvest is now mainly mechanical harvesting, combine harvester is the main machinery for harvesting rice and wheat, because of its larger purchase price, complex structure, so the correct operation, to extend its life expectancy, improve work efficiency, reduce job losses, it is very important. 1. The correct use of combine harvester one is the correct choice of cutting height. According to crop yield, height, maturity and timely adjustment of the harvester forward gear, cutting and cutting height, to minimize long-term overload operation. The second is a reasonable choice of operating speed. When crop maturity is high, the ground is flat, straw is relatively dry, sparse, less weeds,
