盐碱地三种盐生植物生境指标测定及其改土效应分析

Determination of Habitat Indexes of Three Halophytes in Saline-alkali Land and Analysis of Soil Improvement Effects

盐角草、碱蓬、柽柳为三种威海市盐碱地普遍种植的具有耐盐碱特性的盐生植物。本研究通过测定三种植物的生境指标,探究了盐生植物的生长条件和对盐碱化土壤的适应性,并分析了耐盐机理,以期开发盐碱化土壤的生物改良技术,因地制宜地种植盐生植物,拓展盐生植物的资源化利用途径。

Salicornia europaea,Suaeda glauca and Tamarix chinensis are three kinds of saline-tolerant saline plants commonly grown in the saline-alkali land of Weihai City.By measuring the habitat indicators of three kinds of plants,this study explores the growth conditions of halophytes and their adaptability to saline soil,and analyzes the salt tolerance mechanism,in order to develop the biological improvement technology of saline-alkali soil,plant halo⁃phytes according to local conditions,and expand the resource utilization of halophytes.
