| Abstract: | Measurements on water physiological of Haloxlon ammodendron,Calligonum mongolicum,Hedysarum scoparium,Tamarix ramosissima,Caragana microphylla and Elaeagnus angustifolia forest tree species in Minqin oasis desertification restore farmland.The results showed that drought-tolerant tree species with a low water potential,water deficit is large and good water holding capacity,as well as large variations.The characteristics of drought-resistance of seven tree species in descending order of Haloxlon ammalerdron,Tamarix ramosissima,Hedysarum scoparium,Caragana microphylla,Elaeagnus angustifolia,Calligonum mongoliaum. |
