摘　　要：以3种荒漠原生树种蒙古扁桃、沙冬青、旱榆为研究对象,分析在浇水和脱灌2种状况下对其生长状况以及保存率的影响,结果如下:(1)蒙古扁桃在脱灌情况下,平均株高为34.99 cm,总生长量平均为21.99 cm,平均年生长量为11.99 cm,平均冠幅为553.32 cm^2,平均保存率为91.57%;浇水情况下平均株高为46.38 cm,总生长量平均为33.38 cm,平均年生长量为17.09 cm,平均冠幅为791.92 cm^2,平均保存率为95.33%。脱灌情况下蒙古扁桃的生长量有所减少,保存率有所下降。(2)沙冬青在脱灌情况下,平均株高为77.35 cm,总生长量平均为67.35 cm,平均年生长量为37.59 cm,平均冠幅为9 031.59 cm^2,平均保存率为94.63%;浇水情况下平均株高为89.77 cm,总生长量平均为79.77 cm,平均年生长量为45.56 cm,平均冠幅为9 688.73 cm^2,平均保存率为96.93%。脱灌情况下沙冬青的生长量有所减少,保存率也有所下降。(3)旱榆在脱灌情况下平均株高为59.79 cm,总生长量平均为16.79 cm,平均年生长量为25.79 cm,平均保存率为91.57%;浇水情况下,平均株高为51.35 cm,总长量平均为8.35 cm,平均年生长量为18.73 cm,平均保存率为91%。脱灌情况下旱榆的株高增长量有所增长,保存率有所上升。Taking Amygdalus mongolica, Ammopiptanthus mongolicus and Ulmus glaucescens as research object, the influences of watering and getting rid of irrigation have been analyzed on the growth situation and preserving rate of three desert native tree species. The results show,(1) for Amygdalus mongolica in condition of getting rid of irrigation, average height is 34.99 cm, mean value of total increment is 21.99 cm, average annual increment is 11.99 cm, mean crown is 553.32 cm^2, average preserving rate is 91.57%. For Amygdalus mongolica in watering condition, average height is 46.38 cm, mean value of total increment is 33.38 cm, average annual increment is 17.09 cm, mean crown is 791.92 cm^2, average preserving rate is 95.33%. In condition of getting rid of irrigation, the growth increment and preserving rate of Amygdalus mongolica have been dropped.(2) For Ammopiptanthus mongolicus in condition of getting rid of irrigation, average height is 77.35 cm, mean value of total increment is 67.35 cm, average annual increment is 37.59 cm, mean crown is 9 031.59 cm^2, average preserving rate is 94.63%. For Ammopiptanthus mongolicus in watering condition, average height is 89.77 cm, mean value of total increment is 79.77 cm, average annual increment is 45.56 cm, mean crown is 9 688.73 cm^2, average preserving rate is 96.93%. In condition of getting rid of irrigation, the growth increment and preserving rate of Ammopiptanthus mongolicus have been dropped.(3) For Ulmus glaucescens in condition of getting rid of irrigation, average height is 59.79 cm, mean value of total increment is 16.79 cm, average annual increment is 25.79 cm, average preserving rate is 91.57%. For Ulmus glaucescens in watering condition, average height is 51.35 cm, mean value of total increment is 8.35 cm, average annual increment is 18.73 cm, average preserving rate is 91%. In condition of getting rid of irrigation, the height increment and preserving rate of Ulmus glaucescens have been increased.
