通过对41个引进树种的引种试验,得出在低度盐碱地(1‰-2‰)上成活率达90%以上的有26个耐盐树种,经耐盐力测定,银杏、淡竹、红瑞木、沙枣等23个树种为耐盐树种,其中在1.0‰~2.0‰土壤含盐条件下生长较好的有7个树种,在2.0‰-3.O‰土壤含盐条件下生长较好的有8个树种,在3.0‰-4.0‰土壤含盐条件下生长较好的有4个树种,在4.0‰以上土壤含盐条件下生长较好的有4个树种。
Through the introduction test of 41 introduced species, 26 salt-tolerant species with survival rate above 90% were obtained at low salt-alkali soil (1 ‰ -2 ‰) , And jujube are the salt-tolerant species. Among them, there are 7 species which grow well under the salt content of 1.0 ‰ ~ 2.0 ‰, and grow well under the condition of salt content of 2.0 ‰ -3.O ‰ There are 8 species, 4 species grow well under 3.0 ‰ -4.0 ‰ soil salinity, 4 species grow well under 4.0 ‰ soil salinity.
