摘　　要：以西葫芦(Cucurbita pepo L.)为试材,采用潮汐灌溉和顶部洒水(CK)2种灌溉方式,其中潮汐灌溉有2个灌溉时长水平:15 min/次、30 min/次,3个灌溉频率水平:1次/d、1次/2 d、1次/3 d,共7个处理;探讨了潮汐灌溉和顶部洒水2种灌溉方式对西葫芦穴盘苗生长及生理变化、基质电导率、含水量和灌水量的影响。结果表明,与顶部洒水灌溉方式相比,潮汐灌溉的15 min/次、1次/d处理和30 min/次、1次/d处理的穴盘苗素质最佳,且分别节水10%、6%;最优潮汐灌溉制度是灌溉高度为穴盘高度的2/3(3 cm)、灌溉时长为15 min/次、灌溉频率为1次/d。Taking summer squash（Cucurbita pepo L.） as study object, setting two irrigation method between the ebb and flow irrigation and top-irrigation（CK）,where ebb and flow irrigation set two irrigation time levels ：15 min/times,30 min/times,three irrigation frequency levels：1 times/d,1 times/2 d,1 times/3 d,a total of 7 treatment. Effects of ebb and flow irrigation and top-irrigation on plug seedling growth and physiological changes,matrix conductivity and moisture and irrigation amount was studied. The results showed that： Compared with the top-irrigation,plug seedlings quality and saving water tidal irrigation of15 min/times ＋1 times/d and 30 min/times ＋1 times/d are best,and water saving were respectively 10% and 6%;Under certain environmental conditions, the optimal ebb and flow irrigation system was irrigation height is 3 cm, irrigation time is15 min/times, irrigation frequency was 1 times/d.
