犁地在机耕作業中佔首要地位。不仅犁地的質量足以影响其后的作業及直接影响产量,犁地所消耗的能量亦最多。依机械化程度的不同,犁地所消耗的机械能佔全部机耕作業机械能消耗总量的百分数亦不同:在一些以耕耙播为主的我国拖拉机站中有达約70％的;在一些以小麦为主、耕耙播收都机械化了的我国国营农場中有达約40％的;只有多样
Plowing occupies an important position in the work of cultivating the plow. Not only is the quality of the plow sufficient to affect subsequent operations and the production directly, plowing also consumes the most energy. Depending on the degree of mechanization, the percentage of mechanical energy consumed in plowing to the total mechanical energy consumed by the entire tillage machine is also different: about 70% of the total number of tractor stations in our country, There are about 40% of our country-owned farms mechanized by harvesting harrows and harrows; only about 40%
