本研究基于全覆盖膜下沟灌和新型膜下渗灌2种减蒸控漏节水灌溉技术模式,采用田间试验方法,以常规沟灌为对照,对不同灌溉技术的土壤水消耗特点、节水效果及其他综合效果进行了比较。结果表明：采用全覆盖膜下渗灌和膜下沟灌的减蒸控漏节水灌溉技术,番茄全生育期分别较CK节水36.67%和28.87%,产量分别提高21.32%和5.11%;灌溉水利用效率分别为65.15 kg/m3和47.03 kg/m3,分别较CK提高106.24%和48.88%;水分生产效率分别为69.89 kg/m3和53.91 kg/m3,分别较CK提高91.57%和47.78%。膜下灌溉能够降低温室内的空气相对湿度,有效减少病虫害的发生。研究结果可为蔬菜节水灌溉技术大面积生产示范提供技术依据。

Two types of water-saving irrigation techniques of reducing evaporation and controlling water leakage (furrow irrigation under film mulching and infiltration irrigation under new film mulching) were studied. Controlled with normal infiltration irrigation, the water consumption characters of soil, water-saving effect and other comprehensive effect of different irrigation techniques were compared. The results showed that with the two types of water-saving irrigation techniques of reducing evaporation and controlling water leakage, water was saved by 36.67% and 28.87% in the whole growth period, respectively. The yield of tomato increased by 21.32% and 5.11% , respectively. The irrigation water efficiency was 65.15 kg/m3 and 47.03 kg/m3, which increased by 106.24% and 48.88%, respectively. The water use efficiency was 53.91 kg/m3 and 69.89 kg/m3, which increased by 47. 78% and 91.57% , respectively. Irrigation under mulching could significantly decrease the air relative humidity, and effectively reduce the disease and pest. This research could provide technological basis for the production and demonstration of vegetable water-saving irrigation technique in a large area.
