摘要
在1991年冬被皆伐的残次阔叶林中,1993年进行抚育间伐、补植造林、封山等措施试验表明,抚育间伐试验林生长快,1994年平均树高3.2m.改造后1993~1994年两年树高生长量1.8m,与集约经营的1992年新造菇木林相近,菇本产量高,1994年出重20000kg/hm2,超过封山林和新造林。封山林生长良好,总生物量大,林本生长量和菇木产量次之。枫香适应性强,生长较快,是菇木林建设的先锋树种。抚育间伐、补植、封山等措施费用省、效果好,对我区提高现有阔叶林资源的菇木林生产力,具有较好的推广应用价值。
Experiment in 1993 with tending felling, after culture forestation, closing hillsides,etc. insecondary hardwood forest after clear - felling in 1991 showed that average tree height of the forest withtending felling was 3. 2m in 1994. height increment after transformation was 1. 8m, which was similar tonewly forestated mushroom stand in 1992. Fresh weight of mushroom wad veached 20 000kg/hm2, whichwas more than in stand with closing hillsides and new forestation. Beautiful sweetgum is a pioneer speciesfor mushroom forest with strong adaptiveness and quick - growing.
