细枝岩黄耆在高寒条件下育苗试验

Experiment on Raising Seedlings of Hedysarum scoparium under Alpine and Cold Conditions

通过对适生于沙区荒漠生境的灌木树种细枝岩黄耆引种到高寒冷凉山区育苗试验,1年生苗木还不能够用于造林,2年生苗木完全具备造林标准要求,并总结了细枝岩黄耆在高寒冷凉山区条件下的培育技术,为高寒干旱山区造林提供了更多的树种选择空间。经造林实验,苗木成活率和生长情况良好,可以在高寒冷凉山区造林。

On the basis of the experiment on the introduction of shrub trees suitable for desert habitats in sandy areas into cold and cold mountain areas,one-year-old seedlings could not be used for afforestation,and the two-years-old seedlings completely met the requirements of afforestation standards.The cultivation techniques of Hedysarum scoparium in alpine and cold mountain areas were summarized,which provided more tree species selection space for afforestation in alpine and arid mountainous areas.Through afforestation experiment,the survival rate and growth condition of seedlings are good,and it can be planted in cold and cold mountain area.
