| 摘 要： | 运用P-V技术初步研究了人工林胡杨、灰叶胡杨两个树种的水分参数差异，探讨了树种的抗旱性。结果表明灰叶胡杨的主要水分参数(ψ100、ψ0、ROWC、AWC、RWD、ε）明显低于胡杨，渗透调节能力和束缚水含量高于胡杨，表现对干旱环境具有较强的耐旱能力。综合评判表明灰叶胡杨对干旱的适应性较强。

| Abstract: | Difference with water parameters and droght-resistance of Populus euphratica Oliv.and P.pruinosa Schrenk.are preliminary studied by using P-V technique under cultivation condition.The result showed that the mainly water parameters of P.pruinosa Schrenk.were lower significent than Populus euphratica Oliv.,but bound water and osmotic adjustment ability were higher than Populus euphratica Oliv.P.pruinosa Schrenk.has stronger drought-resistance ability under water stress.Comprehensive estimation showed that P.pruinosa Schrenk.has stronger ecological adaption ability to drought environment. |
