摘要
The rootsystem structural characteristics of annual seedlings of Pinus koraiensis, Pinus sylvestris var. mongolica, Larix olgensis and Picea koraiensis were studied with the method of excavation at the nursery of Maoershan Experimental station in the Antumn of 1992. The results showed that there were large differences in some ways, such as their root quantities,distributive depth and dense layers of root systems,etc.
