| Abstract: | Betula halophila is the secondary rare and endangered plants.In this paper we expounded its introduction proces,including the process of making it survive for refined seedlings,transplanting.Six salt gradients(0‰,3‰,5‰,7‰,10‰ and 13‰) were set for testing the salt tolerance of Betula halopila.The results showed that after 37 days,the seedlings under 7‰,10‰ and 13‰ salt treatments were all died,while those under 0‰,3‰ and 5‰ salt treatments grew well.According to the results of salt tolerance test,Betula halophila could grow well at the saline-alkali area with salt content lower than 5‰.In Tianjin City,it was difficult for Betula halophila to grow overwinter in open field,that was because of the high temperature and heavy rain in summer and autumn,so widespread cultivation would be limited. |
