犁苏联每年约生产各种型号的犁20万台,目前犁的保有量已有一百多万台。但每个犁铧的工作负荷仍然不高,近五年内将以生产率高的6～9铧犁代替3～4铧犁,保证不误农时。目前用得最多的是四铧犁,其生产率为0.75～1.05公顷/小时,当采用(?)H—8—35八铧犁与 K—700型拖拉机配套,生产率显著提高(2.2～2.5 Plow The Soviet Union produces about 200,000 plows of various types every year. At present, more than one million plows are held. However, each ploughshare’s work load is still not high, in the past five years, high productivity will be 6 to 9 plow instead of 3 to 4 plow, to ensure that when not wrong farming. At present, the most widely used is the 4-plow plow with a productivity of 0.75-1.05 hectares per hour. When using the H-8-35 eight-plow plow and the K-700 tractor, the productivity is significantly increased (2.2-2.5
