膜上灌是 80年代新疆发展起来的一种地面灌水技术,它改变了传统的大水漫灌浇地的方法,提出了通过株茎孔或膜孔直接浇灌作物的新思路,其灌水效果类似于滴灌,但投资与滴灌相比却相差悬殊,是一种节水效果较好的地面灌水技术。为探讨该项技术在我省的适用性,在威县进行了该项技术的田间试验和研究工作。经试验,棉花膜上灌的灌溉定额为 450— 600m3/ hm2,灌水均匀度达 80%以上。同时在试验中对影响膜上灌灌水质量的主要因素也进行了分析与研究,这为在我省大面积推广膜上灌水技术提供了理论依据。
Membrane irrigation is a kind of surface irrigation technology developed in Xinjiang in the 1980s. It changed the traditional method of irrigating irrigated land and proposed a new idea of irrigating crops directly through the stalk holes or membrane holes. The irrigating effect was similar to that of Drip irrigation, but compared with the investment and drip irrigation are disparities, is a better water-saving surface irrigation technology. In order to explore the applicability of this technology in our province, field experiments and research work on the technology were carried out in Wei County. After testing, irrigation of cotton membrane irrigated quotas of 450-600m3 / hm2, irrigation uniformity of more than 80%. At the same time, the main factors affecting the quality of irrigation water on the membrane were also analyzed and studied in the experiment, which provided a theoretical basis for popularizing membrane irrigation technology in large area in our province.
