我国是主要的马铃薯生产国之一。产量仅次于苏联、波兰,占世界第三位。目前,我国马铃薯收获塞本上是用人工或马拉犁。不仅用工量大且劳动强度和损失都很大。个别地区使用机器收获,大多是仿苏的抖动链式挖掘机。1978年北京十二国农机展览会上展出的样机一般都是体积大、机体重、耗材多、造价高。因 Our country is one of the major potato producing countries. Production is second only to the Soviet Union and Poland, accounting for the third place in the world. At present, the potato harvest in our country is made of artificial or horse plow. Not only large amount of labor and labor intensity and loss are great. In some areas, machines are harvested, most of which are imitation-sucking jitter chain excavators. In 1978, the prototypes exhibited by the 12th National Agricultural Machinery Exhibition in Beijing are generally large in size, heavy in body weight, high in consumables and high in cost. because
