Qilian Sabina Drought-resistance Afforestation Technology

Qinghai has high altitude，drought，and severe cold，poor natural conditions，and poor ecological environment.During process of ecological construction and ecological restoration，there are relatively few tree species available for afforestation.Moreover，Qilian Sabina is one of the fine native tree species in afforestation and afforestation in the cold and drought regions of Qinghai province.The tree species has characteristics of strong adaptability，drought resistance，cold resistance，resistance to barrenness，and developed root system.It is the main tree species for artificial afforestation in the mountainous areasand around Qilian mountain，especially the main tree species for afforestation on sunny slopes.Qilian Sabina is a male and female plant.The highest growth of the tree is up to 12 meters.The trunk is straight，the branches are straight and the trunk looks gray，gray-brown.After the cracking，irregular strips form and then fall off.There are thorny leaves and scaly leaves in the leaves.The appearance of the fruit is ovoid or round and the seeds are oval or oblate.In recent years，Huzhu county of Qinghai province relied on the advantages of Qilian Sabina species in the region，had actively carried out drought-resistance afforestation techniques and had made outstanding achievements.The regional ecological environment had further improved，and the forest coverage had further increased.This research mainly discussed Qilian Sabina′s drought-resistance afforestation technology.
