摘要
沙冬青为轴根系植物，主根粗壮，侧根发达。根系分布与土壤基质条件密切相关，其主体部分集中在０—３０ｃｍ土层内，根瘤位于侧根末端。冠幅平均为０．７６ｍ２的沙冬青，单株平均根系干重２３１．６ｇ、体积４１１．１ｃｍ３、根长７２５．３ｍ、表面积１３７７５ｃｍ２。
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.
