摘要
[目的]调查不同除萌处理对杉木迹地马尾松生长的影响，为马尾松幼林内的除萌工作提供技术参考。[方法]调查不同除萌处理（二次除萌、一次除萌、不除萌）对闽西地区山地杉木采伐迹地更新马尾松树高、胸径、枝下高的影响。[结果]在二次除萌、一次除萌和不除萌处理下，马尾松树高、胸径和枝下高产生了极显著差异；二次除萌处理有利于马尾松树高和胸径的生长发育；一次除萌有利于马尾松枝下高生长发育。[结论]在杉木采伐迹地营造其他树种人工林有利于林地的发展，但是要加强杉木伐桩萌发条的处理。
Abstract
Objective] Effects of different sprouts removal treatments on the growth of Pinus massoniana in Cunninghamia lanceolata cutover land were investigated to provide technical reference for the sprouts removal technology in P.massoniana young forest.[ Method] We investiga-ted the effects of different sprouts removal treatments on the growth of P.massoniana in Cunninghamia lanceolata cutover land in western Fujian. [Result] Under the treatments of second sprouts removal, first sprouts removal and no sprouts removal, there were extremely significant differ-ences in the plant height, diameter at breast height, increment under branch height.The second sprouts removal treatment was helpful to the growth of plant height and diameter at breast height of P.massoniana.The first sprouts removal treatment was helpful to increment under branch height.[ Conclusion] Planting other tree plantations in C.lanceolata cutover land is helpful to the development of forest land.But the germina-tion condition of P.massoniana stump should be strengthened.
