| 摘 要： | 在渐伐后郁闭度不足0.4的沙地樟子松人工林冠下进行人工更新试验,10年后观测各树种的生长状况,并对林下的土壤进行调查.结果表明:利用这种冠下人工更新方式使樟子松纯林转变为多树种混交的复层林;色木槭等4个树种可以作为冠下更新的主培树种;冠下人工更新可以逐渐改良土壤,延缓樟子松人工林林地土壤的衰退.

| Abstract: | Pinus sylvestris var.mongolica plantations were regenerated on sandy land after gradually cutting,with the canopy being less than 0.4.Growth of each species was observed after 10 years and the forest soil were investigated.Result shows that:the use of such a way that artificial regeneration under canopy of pure forest of Pinus sylvestris var.mongolica tree species can be changed into a multi-storied complex;Acer mono & other 4 species can be regenerated as the main species cultivated under canopy trees;crow... |
