盐碱土绿化植物的应用与评价

Application and Evaluation of Plants Greening in Salt Affected Soils

对天津塘沽区、河北黄骅市、山东东营市等地的盐碱土绿化植物的应用状况进行了调查.结果表明:该地区有盐碱土绿化植物34科,87种;现已栽培应用的有63种,其中只有27.5%能耐中度盐碱,多数种类只耐轻度盐碱,没有一种为强耐盐植物;三个地区有野生及乡土耐盐植物种类24种,其中10种为很有价值的盐碱土绿化植物.

Plants greening in salt affected soils in Tianjin Tanggu Area, Hebei Huanghua City and Shandong Dongying City have been studied for 2 years. The results indicate that there are 87 species, belonging to 34 families, among which 63 species have been cultivated and that only 27.5% of them are middledegree salt tolerance plants, most of them are lightdegree salt tolerance plants and no species is of high salt tolerance. We also found there are 24 species of wild salt tolerance plants, 10 of which now greening in salt affected soils are of high value.
