地瓜收获时用工量很大,收获期集中。人工镐刨虽能减少破伤,但进度较慢,霜前不能收完的地瓜易遭冷害,貯藏容易腐烂。过去有用木犁、铁犁和无轮一铧犁畜力牵引收获,虽提高了进度,但薯块破伤很多且收不净。为了解决这一问题,1965年阜新蒙古族自治县在中国农业科学院辽宁分院的配合下,试制成了一种翻转式地瓜犁(简称地瓜犁,图1),用它收 Sweet potatoes harvest labor intensive, harvest concentrated. Although the artificial pick planing can reduce the damage, but the progress is slow, before the frost can not be finished sweet potato chilling injury, perishable storage. Past useful wood plows, iron plows and wheel without a share of animal husbandry plow traction, although to improve the progress, but a lot of broken potato tubers and not clean. In order to solve this problem, in 1965, with the cooperation of Liaoning Branch of Chinese Academy of Agricultural Sciences, Fuxin Mongolian Autonomous County trial made a flip-type sweet potato plow (referred to as sweet potato plow, Figure 1)
