采育择伐适用于异龄复层混交林，特别是中小径木较多的成、过熟林分。结果表明，采育择伐后仍能形成异龄复层混交林，２４年间蓄积量达２２４２３～２８１６３ｍ３／ｈｍ２，是皆伐人工更新红松纯林的２４～３５倍；能提前获得大径材，缩短轮伐周期，增加经济效益；能够保持稳定的森林环境，避免由于皆伐带来的水土流失、更新缓慢、树种单一、生态功能削弱等一系列问题。 Selective cutting and seedling suitable for mixed stratified mixed forest, especially the more small and medium-sized trees, over-mature stands. The results showed that after mixed-seeding, the mixed-layer mixed forest could still form the mixed forest with an age of 22423 ~ 28163 m 3 / hm 2 in 24 years, which was 2-435 Can get large diameter wood in advance, shorten the rotation cycle and increase economic benefits; can maintain a stable forest environment and avoid a series of problems such as soil erosion due to clear cutting, slow updating, single tree species and weakened ecological functions.
