| Abstract: | Ammopiptanthus mongolicus is axial root system,main root is robust and branch root is well developed.The distribution of root system correlates closely to the nature of soil,main part of roots concentrates in 0-30 cm soil layer,root nodules are located at the end of lateral root.The mean weight of root system of single plant of A.mongonlicus,which is 0.76 m2 in crown scope,is 236.ig,volume 411.1cm3,lengch 725.3m,suface area 1377.5cm2. |
