顾名思义,节水型农业是将整个农业生产中可能浪费的水量尽量从各个方面节约下来,以达到最省水、最合理、最高效益的农业;它不是单纯的节水型水利,也不仅仅是节水型灌溉,更不是单纯为了节水,以扩大灌溉面积。而重要的是通过节水以提高单位面积产量,改善农业生态,全面搞好农业生产。 农业上的用水,虽然在一些地方和某一时间内尚嫌不足,但大量浪费水的现象则比比皆是。就从新疆年平均灌溉定额来看,在前些年曾达1100—1200立米/亩,近年来有所下降,平均仍有900余立米/亩,与先进的400立米/亩相较,仍高出一倍以上。足见农 As its name implies, water-saving agriculture is to save as much water as possible in the entire agricultural production as much as possible in order to achieve the most water-saving, most rational and most efficient agriculture. It is not simply a water-saving type of water conservancy, nor is it Water-saving irrigation, more than simply to save water, to expand the irrigated area. What is important is to improve agricultural productivity and improve agricultural production in an all-round way by saving water so as to increase the yield per unit area. Although agricultural use of water is still inadequate in some places and at some time, a great deal of water is wasted everywhere. From the perspective of Xinjiang’s annual average irrigation quota, it has reached 1100-1200 m³ / mu in previous years and has declined in recent years with an average of more than 900 m³ / mu, which is still high compared with the advanced 400 m³ / mu More than doubled. Agriculture can be seen enough
