摘　　要：研究了等渗Ca(NO3)2和NaCl处理对黄瓜幼苗生长的影响。试验结果表明,在等渗的Ca(NO3)2和NaCl胁迫下,黄瓜幼苗的干质量、鲜质量和根系活力与对照(不含Ca(NO3)2和NaCl处理)相比明显降低。黄瓜幼苗受害程度随盐浓度的升高和胁迫时间的延长而加重,黄瓜幼苗盐害指数增加。Ca(NO3)2对黄瓜幼苗的伤害大于等渗的NaCl。The effects of iso-osmotic Ca（NO3）2 and NaCl treatment on growth of cucumber seedlings were studied. The results showed that compared to control the dry weight （DW）, fresh weight （FW）, root activity and salt injury indexes of seedlings were significantly decreased under salt stress. As the expand of NaCl or Ca（NO3）2 concentration, indexes of salinity injury enhanced. Ca （NO3）2 had much more detrimental effects on the growth of cucumber seedlings than iso-osmotic NaCl.
