在造林工作中拖拉机组是用低速工作的。采用手工投苗时,目前不能把植树机的行驶速度提高到3.5公里/小时以上,因为植树机上的植树工平均1.5秒钟能投一株苗。根据这一情况,在植树机目前的构造条件下,最好扩大机组的工作幅度,以便更充分地利用拖拉机的牵引力。在以后进行幼林抚育时,可使用宽幅的中耕机,这样就能够大大地减少资金和劳力的消耗。
The tractor works at low speed in afforestation work. At present, the planting speed of tree-planting machines can not be increased to 3.5 km / h at present due to the seedlings being planted by hand, because the tree-planting workers on the tree-planting machines can cast one seedling every 1.5 seconds on average. Based on this situation, it is advisable to expand the working envelope of the unit under the current construction conditions of the tree-planting machine in order to make better use of the tractive force of the tractor. In later nursery tending, a wide range of cultivators can be used, which can drastically reduce the capital and labor costs.
