摘要
田间施水节水是农业节水的一个重要环节。本文对田间施水节水的各项技术措施、节水潜力进行了论述 ,指出就目前我国的经济现状而言 ,发展节水灌溉 ,田间施水节水的重点应放在加强节水地面灌溉技术及其配套设施和节水灌溉制度的研究与推广上 ,而喷、微灌技术的发展 ,则要因地制宜 ,量力而行 ,并注重实效。此外 ,要特别强调对各项节水技术措施进行适当的综合集成 ,以实现农田灌溉各个环节上的全方位节水 。
Saving water in applying water to farmliand is a key link of saving water in agriculiture. This paper discussed various water-saving techniques and their potentials in applying water to farmland. In view of the economic status of China, saving water in applying water to farmland should put the emphases on the research and extension of water -saving surface irrigation techniques and their necessary facilities as well as water-saving irrigatioin schedules in the course of developing water-saving irrigation. And, the development of sprinkler and low flow irrigation techniques shulld act according to local conditions and capabilities, laying stress on practical effects. In addition, we must strengthen the moderate integration of various water-saving technical measures, achieving to save water in all-round way of farmland irrigation and increasing water use ratio and efficiency maximally.
