中文摘要	通过不同矿化度咸水造林实验和对塔里木沙漠公路防护林工程沿线不同矿化度水灌溉林地进行定位调查,选取成活率、株高、冠幅、地径、地上生物量及结实状况等反映造林苗木生长状况的常规指标,分析了不同矿化度咸水灌溉对乔木沙拐枣(Calligonum arborescons)、梭梭(Haloxylon ammodendron)和多枝柽柳(Tamarix ramosissima)3种植物生长状况的影响.研究结果表明,灌溉水矿化度对这3种植物的成活、营养生长和结实均有显著影响.随矿化度升高,整体表现为抑制作用;盐胁迫影响程度与灌水矿化度存在阈值变化现象.灌溉水矿化度在20 g/L以上时,梭梭不能结实,但成活和生长基本未受影响;乔木沙拐枣和多枝柽柳的存活阈值为15-20 g/L,抗盐阈值分别在15 g/L和20 g/L左右;3种植物抗盐能力依次为:梭梭>多枝柽柳>乔木沙拐枣
英文摘要	Afforestation experiment under saline water irrigation of different mineralization in Xiaotang, and location investigation of the shelter% belt along the Tarim Desert Highway under saline water irrigation of different mineralization were done. Survival rate, height, crown width, ground diameter, aboveground biomass, seed setting condition, and such conventional growth index were selected. Effects of saline water irrigation of different mineralization on growth conditions of Haloxylon ammodendron, Calligonum arborescons, and Tamarix ramosissima under was analyzed and compared. The results show that the mineralization of irrigation water had significant effect on germination and survival, vegetative growth, and seed setting of 3 plants, meanwhile, integrative manifestation was inhibition with rising of irrigation water mineralization, and there is nearly relationship between salt stress and the threshold of irrigation water mineralization. Haloxylon ammodendron had no seed setting when mineralization was above 20 g/L, but survival and growth almost were not affected. The survival threshold of Calligonum arborescons and Tamarix ramosissima was 15-20 g/L, and salt-resistance thresholds were about 15 g/L and 20 g/L.The sequence of salt-resistance ability of 3 plants was Haloxylon ammodendron, Tamarix ramosissima and Calligonum arborescons
