2012年在福建明溪县胡坊镇选取4种厚朴林分进行调查，对平均木采用树干解析法取样，对凹叶厚朴与杉木、绿竹和油茶混交及其纯林的生长规律进行研究。结果表明，凹叶厚朴混交林胸径连年生长量达到最大值的时间（第3年）比纯林早1 a，树高连年生长量（第2年）早3 a，材积连年生长量（第8～9年）早3 a，在前10 a混交林的胸径、树高、材积平均生长量（平均值分别约为1.23 cm、1.42 m、0.0037 m3）始终比纯林（分别约为0.81 cm、1.00 m、0.0027 m3）大；且3种混交林直径、树高和材积的连年生长量和平均生长量达到最大值的时间一致，但数值存在差异：厚杉＞厚竹＞厚油混交林，说明凹叶厚朴与杉木混交能很好地促进凹叶厚朴的生长，混交效果最好，其次为凹叶厚朴绿竹混交林，再次为凹叶厚朴油茶混交林，最差的为凹叶厚朴纯林。

Four kinds of Magnolia stands at Phoebe County Hufang Down in Fujian Province were investigated and sampled by the method of stem analysis in 2012. And then,the growth rhythms of pure and mixed stands of Magnolia biloba,fir,green bamboo,Camellia oleifera were studied. The result showed that the current annual in-crement of DBH of mixed stands reached a maximum in the third year,3 years before pure stand.The current an-nual increment of tree height and volume got to the peak in the 2nd year and 8th -9th year,respectively,3 year ear-lier than pure stand.Moreover,in the first decade,the average increment of DBH,tree height and volume of mixed stands (1.23 cm、1.42 m、0.003 7 m3 )were higher than that in pure stand (0.8 1 cm、1.00 m、0.002 7 m3 ).Meanwhile,in fir,green bamboo and Camellia oleifera mixed stands,the current annual and average incre-ment of DBH,height and volume reached the maximum at the same time,but varied in detailed values.Among them,fir>green bamboo>Camellia oleifera mixed stands.The result indicated that Magnolia biloba and fir mixed stands could be getting the best result,which promote the growth of Magnolia officinalis,and followed by Magnolia officinalis and green bamboo mixed stand,Magnolia officinalis and Camellia oleifera mixed stand.The worse result was pure stand.
