苏联和大多数国家,除了经常遭受风蚀的地区外,土壤的主要耕作是用铧式犁来完成的,其能量消耗是很大的。因此,所有工业发达的国家显著地增加农业拖拉机的功率和牵引力吨级,首先考虑的是提高耕作机组的生产率。在土壤主要耕作过程中,合理地运用拖拉机功率,同时在两个方面采取措施,增加犁的工作幅宽和提高耕作机组的工作 In the Soviet Union and most of the countries, except for the areas often exposed to wind erosion, the main cultivation of soil is done with a plow and its energy consumption is great. As a result, all industrially developed countries have significantly increased the tonnage of agricultural tractors, both power and traction, with the first consideration being to increase the productivity of farming units. In the main soil farming process, the rational use of tractor power, while taking measures in two aspects, to increase the breadth of plow and improve farming unit work
