【摘要】 在总结盐渍化土壤沙地柏(Sabina vulgar)造林技术的基础上,分析了造林效果与土壤盐渍化程度的关系。结果表明:随着土壤盐渍化程度的加重,土壤pH值、水溶性盐总量、盐离子质量分数上升,而土壤含水率、沙地柏造林保存率及匍匐茎的增粗、延伸、分枝能力和覆盖率下降。因此,在盐渍化土壤上进行沙地柏造林,必须采取适宜的措施进行抑盐、排盐。更多还原

【Abstract】 Based on summarizing afforestation technology for Sabina vulgarin salinized soil,the relationship between afforestation effect and the extent of soil salinization were analyzed.Result shows that:with the increase of severity for soil salinization, soil pH,the total amount of water-soluble salts,salt ion mass fraction increase,but the soil moisture,afforestation preservation rate of Sabina vulgar,and thickening,extention,capability of branching &coverage of stolons declined.Appropriate measures must be taken to suppress and exclude salt.更多还原
