作物生长期中,在植株之间进行锄草、松土叫做中耕。中耕可以使土壤的表层疏松,防止水分蒸发,使空气流通,提高土壤温度,加速肥料的分解,消灭杂草,从而促进作物生长。中耕拖拉机主要用于中耕作物行间管理,也兼用于其他作业,其特点是轮胎较窄、离地间隙较高,具有良好的行间通过性、转向操纵性和视野。20世纪20年代,中耕拖拉机开始出现,用来代替马匹和骡子等畜力,有效提高了小型农场的生产力,减少了雇 During crop growth, weeding between plants, loose soil is called cultivating. Cultivation can make the surface of the soil loose, prevent water evaporation, air circulation, increase soil temperature, accelerate the decomposition of fertilizers, eliminate weeds, thereby promoting crop growth.
