| 摘 要： | 在野外和室内观测5种沙拐枣的生物生态特征及其水分生理指标。结果表明:白皮沙拐枣和新疆沙拐枣以大蒸腾,较强的持水力,保持较高的束缚水来抵抗干旱;乔木状沙拐枣则以较强持水力,最低限度的蒸腾强度抵抗干旱。综合指标分析表明:白皮沙拐枣和乔木状沙拐枣的耐旱性较强,新疆沙拐枣和红皮沙拐枣次之,小果沙拐枣的耐旱性最弱;抗风蚀能力由强至弱为:红皮沙拐枣>新疆沙拐枣>小果沙拐枣>白皮沙拐枣>乔木状沙拐枣。4h为5种沙拐枣失水的拐点,因此,在进行植苗造林中,最好在起苗后4h内栽植,以提高造林成活率。 |

| Abstract: | The properties of biological,ecological and physiological indexes of water on five species of Calligonum spp.were measured.The results showed that Calligonum leucocladum(Schrenk) Bge.and C.klementzii A.los.defense the dry condition with much more transpiration,water-retaining and bound water and C.arborescens Litr.with much more water-retaining and less transpiration.By a synthesized indexes,the grade of capacity on the drought resisting is Calligonum leucocladum(Schrenk) Bge.,C.arborescens Litr.,C.klementz... |
