摘　　要：采用模拟土壤盐渍化的方式,研究不同浓度NaCl盐处理对番茄生长发育的影响。结果表明:在番茄幼苗期,低盐胁迫促进番茄幼苗生长,增加地上部、地下部干鲜重和株高;高盐胁迫抑制幼苗生长,明显降低幼苗地上部和地下部干鲜重、株高和茎粗。The effects of different concentrations of NaCl on the growth and development of tomato were studied by simulating soil salinization in vegetative soil.The results showed that:In tomato seedling stage,low salt stress promoted the growth of tomato seedlings,and increased the dry and fresh weight of overground and underground parts and plant height;High salt stress inhibited the growth of seedlings,and significantly reduced the dry and fresh weight of overground and underground parts,plant height and stem thick of seedlings.
