湖南省许多地区,过去都是用脚踩田,这样,密植时,不但很费劲,而且工作效率也非常低,每工只能踩田六、七分。为此,我们创制出三滚牵引式六行、八行、十行及十二行水稻中耕器与手推式三行、四行中耕器,平均每部二人可中耕15—30亩,中耕质量亦较好。这种新型的三滚中耕器,制造简单,花钱不多。除滚轴、铁套筒和铁圈需由铁匠锻 In many parts of Hunan Province, the land was trampled on the ground in the past. In this way, it was not only laborious but also very inefficient at close planting. Only 6 or 7 can be stepped on per work.
