采用全根挖掘的方法对塔克拉玛干沙漠腹地的成年塔克拉玛干柽柳根系分布的范围、垂直深度和特征分别进行了测量和研究.塔克拉玛干柽柳浅层侧根根系的形态分布与沙漠腹地的主导风向有着密切的关系;同时,垂直根分布深度受地下水水位的抑制.植株迎风面根系重量和长度的分布远远小于背风面.与此同时,柽柳背风面根径厚度相对于迎风面有明显增加.因此,塔克拉玛干柽柳对沙漠腹地多风生境的适应性响应是通过增加其背风面根系的分布和根径的厚度来实现的.
The root range distribution, vertical depth and trait of adult Takulia koraiensis in the hinterland of Taklimakan Desert were measured and measured by the method of total root excavation.The morphological distribution of the lateral root of Taklimakanma shrub was closely related to the dominant wind direction in desert hinterland. At the same time, the depth of vertical root distribution was restrained by the groundwater level.The distribution of root weight and length on the windward surface of the plant was much less than that on the leeward surface.At the same time, the root thickness of the leeward Leebian increased significantly compared with that on the windward surface.Therefore, The adaptive response of windy habitat in the desert hinterland is achieved by increasing the distribution of root systems and the root thickness of the leeward surface.
