| 摘 要： | 通过对梭梭及其它几种植物解剖学及水分生理指标的测定结果表明,以相对含水率和自然饱和亏缺为指标排出的几个种抗旱性由强到弱的顺序是:梭梭>油蒿>柠条>沙枣。以临界水分饱和亏缺为指标排出的几个种抗旱性由强到弱的顺序是:梭梭>柠条>油蒿>沙枣。梭梭及其它几种植物各指标间的不同步性反映了几种植物对干旱的适应方式不同。用主成分分析法对几种植物抗旱性综合评定结果表明,梭梭在所测几种植物中抗旱性最强,这种特性大大提高了其在库布齐沙漠稳定生长的可靠性。

| Abstract: | By studying on water relationship and xerophilous structure of Haloxylon ammodendron by man and some other plants in Kubuqi Desert,moisture physiologic directing sign showed that drought resistance from strong to weak was: Haloxylon ammodendron > A.ordosica Krasch > Caragana > E.angustifolia L.according to relative humidity ratio and natural saturation wane and Haloxylon ammodendron > Caragana>A.ordosica Krasch > E.anagustifolia according to critical saturation wane.Drought resistance of several plants was ... |
