摘要: 为福建含笑的资源开发和最大利用提供理论依据,通过选取平均木和采用树干解析法,研究福建含笑在与杉木混交的林分以及纯林林分中的树干生长规律。结果表明,福建含笑在与杉木混交的林分中胸径连年生长量达到最大值的时间比福建含笑纯林早1年,树高连年生长量早4年,材积连年生长量早3年,而且在前10年混交林的胸径、树高、材积的平均生长量始终比纯林大,说明与杉木混交能够很好地促进福建含笑的生长,福建含笑与杉木是一组很好的混交树种。

Abstract: In order to provide guidance and basis for resource development and maximum utilization of Michelia fujianensis Q.F.zheng, the method of choosing average tree and adopting stem analysis was conducted to study the growth rhythm of stem between the mixed forest of Michelia fujianensis Q.F.zheng and Cunninghamia lanceklata and the pure stand of Michelia fujianensis Q.F.zheng.It was showed that the time of the annual increment of breast in the mixed forest of Michelia fujianensis Q.F.zheng and Cunninghamia lanceklata to the maximum was one year earlier,that of the annual increment of tree heigjt was four years earlier and that of the annual increment of volume was three years earlier,compared with the pure stand of Michelia fujianensis Q.F.zheng,and the average increment of breast,height and volume of the mixed forest was always more than that of the pure shand,it was illustrated that the mixed forest can promoted the growth of Michelia fujianensis Q.F.zheng and the mixed forest of Michelia fujianensis Q.F.zheng and Cunninghamia lanceklata was the best of mixed species.
