关中地区作物复种指数较高、面积大。每年的三夏和三秋农忙季节中,二十余天要全部复种完玉米和小麦,劳力和时间都很紧张。另外,这里水浇地面积也较多,现有的作业机械不适应畦埂田作业,耕作时,原有的畦埂全部破坏,需用人工重新筑埂。根据这种情况,我们在总结多年的农田系列化作业、筑埂机、犁播机等经验的基础上,设计成功“一条龙”作业犁(综合作业犁),用东方红—54(或75)拖拉机牵引,一次能完成耕地、耙地、筑埂、平畦、 Guanzhong crop cropping index higher, large area. Every summer three summer and three autumn busy season, more than twenty days to all finished corn and wheat, labor and time are very tense. In addition, there is also a large area of ​​irrigated land, and the existing work machines are not suitable for Yudan field work. During cultivation, all the original salamanders are destroyed, and artificial rebuilding is required. According to this situation, on the basis of summing up many years of farmland serialization operations, building machines, plowing machines and other experiences, we have successfully designed “one-stop ” plow (integrated operation plow), with Dongfanghong -54 ( Or 75) tractor traction, once completed arable land, rake, build 埂, flat 畦,
