| 摘 要： | 在海滨湿地分别4个盐度梯度，12种杨树、柳树新无性系田间扦插试验结果表明：在苗期，不同杨树、柳树无性系的成活率、保存率、生长量等均与土壤含盐量呈负相关；在出苗期的耐盐能力，1-74杨、1-69杨可达0．241％，35杨为0．188％，J30-16、J35-13、J4-34、J31-17柳为0．089％，其余5个柳树无性系均在0．060％以下；在苗木生长期，其耐盐极限分别为0．343％，0．333％和0．201％。

| Abstract: | A field experiment was designed to research the seedling salt-tolerance of 12 new poplar and willow clones , together with 4 levels of salinity treatment on the seashore marsh. The results showed that high salt content caused the survival rate, conservation rate and biomass of the seedlings to decrease obviously. Among seedling stage, the salt-tolerances of clones were as follows: I-74,I-69 poplar clones about 0.241%; 35 poplar clone about 0.188%; J30-16, J35-13, J4-34, J31-17 willow clones about 0.089%. In the seedling growth period , the salt-tolerances of the above-mentioned clones were 0.343%, 0.333% and 0.201% respectively. |
