We investigated the effects of salt irrigation with 5000ppm saline, 6mm/day (salt irrigated plot) and 3mm/day (dry-salt irrigated plot), and fresh water (control plot) on growth of Poplus alba. Growth and biomass except of root in salt irrigated plots were higher than in the others, especially lowest in dry-salt irrigated plot, but root biomass was not different among treatment plots. This plants under saline irrigation were maintained their lives to control the balance of their above ground biomass to the total one and energy consumption. Amounts of photosynthesis and transpiration for Poplus alba with salt irrigation were decreased, and their diameter growths also were declined, compared with those in fresh water irrigation. As a result water efficiency of this plant was become larger and absorbed salt was sunk in roots, and this mechanism seems to have the salt tolerant strategy for this species. The place of origin for Poplus alba is China and we analyzed physiological characteristics of this species grown under different environments, in Japan (Tottori, Hokkaido) and China (Inner Mongolia). Photosynthesis rate of this species was not different among investigated place, which shows that they keep original genetic adaptabilities in each grown place. Growth of plant on salt accumulated soil was affected by level of water table and its changes. We investigated the effect of water level on high salt tolerant plant (Tamarix chinensis) with salt irrigation of 2000ppm, and there was no growth decrease by salt irrigation, but penetration of their roots to deeper soil layer was prevented around logging water level. Salt contents of the plants in treatments changed water level were higher than those in fixed water level.

我们研究了 5000ppm 盐水、6 毫米/天（盐灌区）和 3 毫米/天（干盐灌区）和淡水（对照区）的盐灌对白杨生长的影响。盐灌地块除根外的生长和生物量均高于其他地块，特别是干盐灌地块最低，但根系生物量在处理地块之间没有差异。维持盐灌下植物的生命，以控制其地上生物量与总生物量和能量消耗的平衡。与淡水灌溉相比，盐灌白杨的光合作用和蒸腾量减少，直径生长也减少。结果，该植物的水分效率变大，吸收的盐分沉入根部，这种机制似乎具有该物种的耐盐策略。白杨的原产地是中国，我们分析了该物种在日本（鸟取、北海道）和中国（内蒙古）不同环境下生长的生理特征。该物种的光合速率在不同的调查地点没有差异，这表明它们在各个生长地点都保持了原有的遗传适应性。积盐土壤上植物的生长受地下水位及其变化的影响。我们研究了水位对2000ppm盐灌的高盐植物（柽柳）的影响，盐灌没有导致生长下降，但在测井水位附近阻止了其根部向更深的土壤层渗透。变化水位处理的植物盐分含量高于固定水位处理。
