所谓软管灌溉,就是采用质轻、高强、抗老化、耐磨损的新型塑料软管,套在水泵出口处,将水输送到农田各处灌溉农作物的方法。这种新技术方法简单,效益显著。软管灌溉与土渠灌溉相比,节水率高达35％～40％,每公顷农田供水耗时减少5小时;软管灌溉与喷灌相比,节水3％～5％,每公顷材料费减少95％以上,节油45％～55％。由此可见,推广软管灌溉技术大有前途。但在实际应用时应注意以下几点:①宜选择小型、易搬运水泵、离 The so-called hose irrigation, is the use of light, high strength, anti-aging, wear-resistant new plastic hose, set in the pump outlet, the water is delivered to the farm irrigation methods throughout the crop. This new technology is simple and effective. Hose irrigation Compared with soil and canal irrigation, the water-saving rate is as high as 35% -40%, and the water consumption per hectare of farmland is reduced by 5 hours. Compared with sprinkler irrigation, the hose irrigation saves 3% -5% of the material cost per hectare Reduce 95% above, save 45% ~ 55%. This shows that the promotion of hose irrigation technology promising. However, in practical applications should pay attention to the following points: ① should choose small, easy to carry pumps, away from
