Abstract: This paper described the effect of cotton stalk isolator applied in soil on garden plants and soil characters of coastal saline soils. Cixi beach was selected as it is representative for the Hangzhou gulf. The soil characters and growth status of garden plants were investigated for almost one and half year in both control and cotton stalk isolator treatment. After one and half year planting, the salt content of surface layer (0 ～ 30 cm soil depth) in both control and cotton stalk isolator treated soil decreased tremendously, the pH decreased slightly, and the organic matter of the soils increased a little. As the cotton stalk isolator applied in coastal saline soils could restrain salt from up going with the capillarity of soil water, in comparison with the control, salt content of cotton stalk isolator treatment decreased significantly. The growth status of some garden species was also improved greatly by applying cotton stalk isolator in coastal saline soils.
