摘　　要：以"津优35号"黄瓜为试材,采用基质穴盘育苗,研究了穴盘不同打孔方式对黄瓜幼苗生长发育的影响,以期明确侧开孔穴盘的育苗效果和节水效果。结果表明:底开孔处理平均每穴盘浇水总量为14.712kg,侧开孔处理平均每穴盘浇水总量为12.298kg,侧开孔处理比底开孔处理少浇水16.41%。侧开孔穴盘在黄瓜整个育苗阶段的浇水总量少于底开孔穴盘,其节水性显著。侧开孔处理比底开孔处理黄瓜幼苗长势好,表现在株高较高、茎粗较粗、生物量较大,壮苗指数较高,侧开孔处理的黄瓜幼苗壮苗指数为0.0117,比底开孔显著高23.16%,其育苗效果显著。Taking ‘Jinyou 35’ cucumber as test material,using matrix plug seedlings,the effect of different perforated hole on cucumber seeding were studied,in order to define the side hole open plug’s effect on plug seedling growing and watersaving.The results showed that each of the bottom hole open plug seedlings need 14.712 kg water on average in total,and each of the side hole open plug seedlings need 12.290 kg water on average totally.Watering a side hole open plug seedling would save 16.41% water than watering a bottom hole open seedling.In the whole growing process,the side hole open cucumber seedlings were growing better than the bottom hole open seedlings,such as higher plant height,thicker stem diameter,larger biomass,and higher seedling index at 0.0117 of side hole open seedlings,which was 23.16%more than the bottom hole open ones,it was remarkable growing effect.
