Growth Characteristics Investigation and Drought Resistance Characteristics Analysis of Caragana roborovskyi
ZHANG Huaizhong
Abstract：In order to develop and utilize Caragana roborovskyi efficiently,we set up sample plant and plot in the arid region Qilian Mountain,investigated the characteristics of branch and leaf growth,root distribution,seedling production and plant dormancy,and analyzed drought resistance characteristics based on investigation results.The result showed that the crown of Caragana roborovskyi was low,branch was covered by prickle,root distribution showed umbrella-type,main root stretched into soil deeply.The propagation from stool shoots was main modality of seedling production,and the propagation from seeds was secondary modality;the dormancy has characteristics entered early and exited late,the drought resistance characteristics of Caragana roborovskyi was showed by leaf growth,root distribution,seedling production and plant dormancy from reduced water evaporation,absorbed deep soil water,increased propagation success rate and avoided adverse growth conditions,and mastered and followed drought resistance characteristics has certain guiding function to utilization efficiently of Caragana roborovskyi.
