摘　　要：为了科学利用沿海滩涂等盐渍土壤资源,研究了6种蔬菜幼苗对不同海水盐度的适应性。结果表明,在盐度为0.50%时,6种蔬菜幼苗的存活率均在60%以上,且辣椒、萝卜、西红柿幼苗的根系活力与叶绿素含量均高于对照;当盐度升至1.00%时,辣椒、萝卜、西红柿、南瓜、黄瓜和青菜幼苗的存活率分别为91.7%、50.0%、50.0%、33.3%、16.7%和0.0%。说明辣椒的盐适应性较强,萝卜和西红柿中等,南瓜较差,黄瓜和青菜最差。0.50%的盐度更有利于辣椒、萝卜和西红柿幼苗的代谢与生长,这与幼苗体内脯氨酸积累较多有关。To make use of coastal mud flat soil resources,salt-adaptability of six kinds of vegetable seeding in ditferent salt concentration was studied. The results showed survival rate of six varieties of vegetable seeding all was more than 60% , and root vigor and chlorophyll content of C. annuum, R. sativus, C. esculentum were higher than control when medium salinity was 0.50%. Survival rate of C. annuum ,R. sativus , C. esculentum , C. moschata, C. sativus, and B. chinensis were 91.7%, 50.0%, 50.0% , 33.3%, 16.7% , and 0.0% , respectively, when medium salinity increased to 1.00%. Salt-adaptability： C. annuum was better,R, sativus and C. esculentum were medium, C. moschata was poor, C. sativus and B. chinensis were the worst. It showed that growth of three vegetables were favorable at 0.50% salinity due to proline accumulation.
