摘　　要：为探讨日光温室春夏茬番茄在渗灌条件下的最佳灌溉制度,采用多元统计主成分分析方法,对日光温室渗灌方式下番茄的产量、水分利用效率、品质进行综合评价。结果表明,渗灌条件下,在番茄苗期、开花着果期、结果盛期、结果后期,土壤水分下限分别控制在田间持水量的60%～70%,75%～85%,75%～85%,70%～80%时,可获得高产、优质、节水的最佳效果。To approach a better irrigation regime for spring/summer tomato in greenhouse under subsurface irrigation, with method of multi-element main component analysis this paper comprehensively evaluated yield, water use efficiency, quality of tomato in greenhouse under subsurface irrlgaiion. The results showed that when the lower limit of soil moisture was 60 -70 percent of field capacity at the seedling, 75 - 85 percent of field capacity at the fruitsetfing and flowering, 75 -85 percent of field capacity at the peak of fruiting, 70 - 80 percent of field capacity at the end of fruiting under the subsurface irrigation, it could＇obtain the best results of high yield, high quality and water-saving.
