现在的人种地,什么都讲究机械化,如耕地用拖拉机,播种用播种机,插秧用插秧机,收割用收割机。可我就没有见过后期用机械追肥的,除用飞机大面积施肥外。如今我就想到了一种新的机械化追肥法。普通的抽水机只可以浇地,不可以施肥。 Now people race, everything about mechanization, such as cultivated land tractors, seeders with seeders, transplanter transplanter, harvesting harvesters. But I have not seen the late use of mechanical dressing, in addition to using large area aircraft fertilization. Now I think of a new mechanized dressing method. Ordinary pumps can only be irrigated, can not fertilize.
