摘要
我国西北干旱地区次生盐碱地的主要造林树种的抗盐碱上限指标：新疆杨可以在土壤含盐量＜６ｇ／Ｌ时生长正常；杜梨＜４ｇ／Ｌ；柠条＜７ｇ／Ｌ；花棒＜５ｇ／Ｌ；沙棘＜６ｇ／Ｌ；沙枣＜４ｇ／Ｌ；枸杞＜７ｇ／Ｌ；梭梭＜３０～５０ｇ／Ｌ；胡杨＜８ｇ／Ｌ；柽柳＜５０ｇ／Ｌ；杨柴＜６ｇ／Ｌ。树种耐盐碱能力的顺序由大到小为：梭梭、柽柳、胡杨、枸杞、柠条、杨柴、沙棘、新疆杨、花棒、沙枣。
The research on the slat tolerance index of main afforestation tree species in arid and semi arid areas with secondary salinization was carried out during the year 1991～1995,and the index of salt tolerant were as follows: Populus enphratica Oliv.<8 g/L P.alba var pyramidalis Bge.<6 g/L Lyeium chinese Mill.<7 g/L Tamarix ramosissima Ledeb<50 g/L Hedysarum scoparium Fisch.et Mey.<5 g/L Hedysarum mongolicum Turcz.<6 g/L Elaeagnus angustifolia L.<4 g/L Hippophae rhamnoedes L.<6 g/L Haloxylon ammodendron (Mey).Bunge<30～50 g/L Pyrus betulaefolia Bge.<4 g/L Caragana intermedia Kuang et H.<7 g/L The ordination for capability of salt tolerant species is from strong to weak: Haloxylon ammodendron,Tamarix ramosissma,Populus enphratica,Lyeium chinese,Caragana intermedia,Hedysarum mongolicum, Hippophae rhamnoides,Populus alba,Hedysarum scoparium,Elaeagnus angustifolia and Pyrus betulaefolia.
