- 摘要:
- 以黄河三角洲1~3龄的柽柳人工林为研究对象，采用分层分段挖掘法，研究了1~3龄柽柳根系的分布特征及生长动态。结果表明：随着树龄和土壤层数的增加，细根数量占总根比例减少；根系生物量多分布于中上层；随着树龄增加，比根长和根长密度最大值出现于40~80 cm土层。因此，肉苁蓉接种深度应该在40~80 cm土层。
- Abstract:
- Taking 1~3 year-old Tamarix chinensis plantation in the Yellow River Delta as research object,the root distribution characteristics of 1~3 year-old Tamarix chinensis plantation were studied by hierarchical segmentation method.The results showed that with the increase of T.chinensis age and the depth of soil layers,the proportion of fine roots reduced.Root biomass distributed in the middle and upper soil layers.With the increase of T.chinensis age,the maximum of specific root length and root length density occurred in 40~80 cm soil.Therefore,the planting depth of Cistanche should be 40~80 cm.
