【摘要】 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。更多还原

【Abstract】 Through making the introduction experiment on 41 species’of trees, it is concluded there are 26 salt-resistant species of trees with more than 90 percent of the survival rate lanted in the lower salty soil (0. 1 -0. 2 percent of salt). 23 species of trees are assessed as salt tolerant species after measuring their tolerance of salinity such as ginkgo, Phyllostachys glauca, Swida alba, Elaeagnus angustifolia, etc. In the different soils with salt contents of 1 ‰ - 2‰, 2‰ - 3‰, 3‰ - 4‰ and over 4‰ thousandth ,7,8,4 and 4 species of trees grown well respectively.更多还原
