摘要
在杭州湾慈溪滨海滩涂设置棉花秸秆隔离层,研究其对于滨海滩涂土壤及绿化植物的影响。结果表明:杭州湾慈溪滩涂对照区通过种植绿化植物1年半后,0～30cm滩涂表层土的含盐量大幅下降,土壤pH值略有降低,土壤有机质含量略有增加;设置棉花秸秆隔离层,能够显著地降低杭州湾慈溪滩涂盐渍土盐分,抑制冬季返盐作用;秸秆隔离措施能显著改善部分植物种类在滩涂的生长状况。
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 beth 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.
