地面灌水技术的改进

The Improvement of Ground Irrigation Techniques

改进地面灌水技术,是灌区提高灌水质量、实行定额用水的关键问题。改进灌水技术,实行定额用水,可显著提高灌溉效益。小畦灌与沟灌、沟灌与隔沟灌都具有增产节水作用,应选择合理的畦灌与沟灌技术要素,制定合理的灌水技术方案。

The improvement of ground irrigation techniques is a key problem for the irrigated area to increase the quality of irrigating water and practice rated water consumption. The improvement of the irrigation techniques and the practice of rated water consumption can increase the irrigation benefit obviously. The small ridge irrigation, furrow irrigation and every other furrow irrigation have the effect of yield increasing and water saving. The rational technical factors of the ridge irrigation and furrow irrigation should be adopted, and the rational scheme of the irrigation techniques should be formulated.
