膜下滴灌技术是改变千百年来大水浸灌方式的一种节水措施,将过去水直接浇地改变为水直接浇作物,按照作物最佳的需水量进行灌溉,用少量的水取得较高的效益,从而提高了水的利用率,是传统农业向高产优质高效农业转变的有效措施。 Underwater drip irrigation technology is a water-saving measure to change the way of floodwater infiltration for thousands of years. The former water is directly poured into the ground and the water is directly poured into crops. The crops are irrigated according to the optimum water requirement of the crop and taken with a small amount of water Higher efficiency, thereby increasing the utilization of water is the traditional agriculture to high-yielding high-quality and efficient agricultural transformation of effective measures.
