Taking ‘Qiushuifurong’，‘Liandanlu’，‘Tanxiangshizi’，‘Qianxiuyinzhen’，‘Caixia’ five species of precious Chrysanthemun as test material，the rapid identification on the salt-tolerance ability of five species of Chrysanthemun were studied through train leaves in circular.The results showed that when NaCl concentration was 0.2 mol/L as screening salt-tolerance，the salt-tolerance identification of precious Chrysanthemun could be identified out in 48 h.It was a rapid identification method on the salt-tolerance of precious Chrysanthemun as cycle short，simple method，low cost，repeatable method.
