摘　　要：[目的]筛选出上海适生的能源柳品种。[方法]引进苏柳、竹柳等4种乔木柳,进行栽植、地插繁育、盆栽、水培等试验,研究物候、生物量、适应性等。[结果]竹柳、J795、J172、J799移栽成活率均达90%以上,年平均单株生物量分别为0.80、0.85、0.87、0.75 kg/株,差异不显著;盆栽时,竹柳盐土盆栽成活率达100%,J172盆栽成活率达83.33%,且最长枝条长度及基径相对黄沙盆栽减幅小;水培耐盐试验,耐盐性强弱依次为竹柳>J795>J172>J799。[结论]4种柳树均可在上海应用,其中耐盐性强的品种为竹柳、J172、J795,J799耐盐性相对较弱,盐土地谨慎应用。[Objective] To select the suitable varieties of energy willow to be planted in Shanghai.[Method] Four willow varieties,including bamboo willow and Salix jiangsuensis J795,J172,J799,were introduced,after being planted,bred,and cultivated in water,their phenology,Biomass and adjustability were studied.[Result] The transplanting survival rate of bamboo willow and Salix jiangsuensis J795,J172,J799 was more than 90% and their single yearly biomasses were 0.8,0.85,0.87 and 0.75 kg per plant respectively without a distinct difference.When planted in pots,the survival rate of bamboo willow was 100%,and that of Salix jiangsuensis was 83.33%,and the length of their longest branches,basal diameter of their stocks decreased the least compared to that planted in the yellow sand.Their order of tolerance to salt from strong to weak was bamboo willow,Salix jiangsuensis 795,172,799.[Conclusion] The four willow varieties can be applied in Shanghai,among which J799 showed the weakest tolerance to salt,thus should be carefully used in saline land.
