不同林地清理方式对油松幼苗生长的影响

摘要

To illustrated the effect of different ground clearances on Pinus tabulaeformis seedlings, four ground clearances were set up. The results showed that treatment 4 had the maximum seed germination stem height, which was 4.67% and 5.97 cm, and the increment was 251.12% and 44.21% compared with the control, respectively. Treatment 4 also had the maximum biomass compared with other treatments. But there were no significant variations of stem diameter of different ground clearances. Thus, it is necessary to cleaning shrubs, herbs and litters at the right time for seedlings growth for Pinus tabulaeformis.%不同林地清理方式对油松幼苗生长的影响的结果表明，处理4种子萌发率和幼苗苗高最高，分别为4.67%和5.97 cm ，分别比对照组高251.12%和44.21%，且处理4根、茎生物量优于其他处理，但不同清理方式对油松幼苗地径影响较小。
