为给营造针阔混交林和提高林地生产力提供理论依据,探索了林窗和林下环境不同埋藏深度对栲树和小叶栲种子萌发率和幼苗存活率的影响.结果表明,随着埋藏深度的增加,栲树和小叶栲种子萌发率和幼苗存活率降低,林窗种子萌发率和幼苗存活率高于林下,种子死亡率低于林下,埋藏过深对栲树和小叶栲种子萌发、幼苗存活及森林更新会产生不利影响.结论:埋藏深度为0.5 cm有利于栲树和小叶栲种子萌发,林窗比林下更有利于栲树和小叶栲种子萌发和森林更新.%The effects of different burial depth on the germination of C. fargesii and C. cariesii were explored in gap and understory environment to provide a theoretical reference for building theropencedrymion and enhancing forest land productivity. The results showed that the seed germination rate and seedling survival rate of C. fargesii and C. cariesii decreased with the increase of burial depth. The seed germination rate and seedling survival rate in gap environment was higher than that in understory environment. But the seed death rate was lower than understory. Too deep in the ground had negative effects on seed germination, seedling survival and forest regeneration of C. fargesii and C. cariesii. Conclusion; The burial depth of 0. 5 cm is beneficial for seed germination of C. fargesii and C. cariesii. And the gap environment is more suitable for seed germination and forest regeneration of C. fargesi and C. cariesii than understory environment.
