This paper studies the effects of salt stress on the growth of Taxodium'Zhongshanshan'seedlings,and explores the characteristics of salt tolerance of Taxodium'Zhongshanshan'seedlings,so as to provide a reference for the planting industry of Taxodium'Zhongshanshan'in Dongtai,Jiangsu.This paper set up four NaCl concentration treatments(0mmol/L,50mmol/L,100mmol/L and 150mmol/L)to measure the growth,chlorophyll content,and photosynthetic parameters of Taxodium'Zhongshanshan'seedlings under different treatments.The results show that salt stress had a significant effect on the growth,chlorophyll content and photosynthetic parameters of Taxodium'Zhongshanshan'seedlings,but the effect of salt stress was not significant when the NaCl concentration was lower than 100 mg/g.It is concluded that Taxodium'Zhongshanshan'has a certain degree of salt tolerance,and it is necessary to choose the environment with NaCl concentration lower than 100mg/g during the planting process of Taxodium'Zhongshanshan'seedlings.
