摘要
通过在水利部灌溉试验总站2年的试验研究,提出软管涌流灌溉配套垄膜沟种耕作方式的节水灌溉综合技术模式,提高了灌溉水的利用率,解决了微灌技术成本高和操作难度大等难题,探讨了微灌设施用于大田作物灌溉的可行性方案。
The surge Irrigation belongs to local irrigation, comparing to the dripping irrigation, it has more excellence, such as strongly jam resistance, low operation pressure and irrigation uniformity, it costs per area less than common dripping irrigation. By means of the two years＇ experiment in the general irrigation station of Water Conservancy Department, we raise a new economizing-water irrigates to synthesize the technique mode which is in the way of soft tube surge irrigation with field ditch, and this not only raises the utilization ratio of irrigation water, but also solves some difficult problems, such as high cost in tiny irrigation and difficulty in operation, and approach the feasibility plan of applying tiny irrigation facilities in the farmland irrigation.
