摘　　要：为探讨日光温室春夏茬番茄的最佳灌溉模式,采用多元统计主成分分析方法对日光温室渗灌、滴灌、小管出流3种灌溉方式下番茄形态指标、生理指标、产量、水分利用效率、品质进行综合评价。结果表明：渗灌、滴灌较小管出流利于番茄植株的生长;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 study the best irrigation mode for spring and summer tomato in greenhouse,the growth indexes（morphological,physiological indicators） and irrigation indicators（yield,water use efficiency,quality） of tomato in greenhouse under three kinds of irrigation modes,namely subsurface irrigation,drip irrigation and small tube flow,were comprehensively elevated by using the multivariate statistical principal component analysis method.The results showed tha both subsurface irrigation and drip irrigation were more helpful than small tube flow to the growth of tomatoes.Under subsurface irrigation,when the lower limit of soil moisture is 60%~70% percent of field capacity at the seeding,75%~85% percent of field capacity at the fruiting and flowering,75%~85% percent of field capacity at the peak of fruiting,70%~80% percent of field capacity at the end of fruiting,the best results of high yield,high quality and water-saving can be got.
