| Abstract: | 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. |
