摘要
通过对福建青冈人工林和杉木人工林的生长对比试验,表明35年生福建青冈的胸径生长明显慢于杉木,但其树高生长量明显高于相同立地条件下的杉木。同时进行了在杉木林冠下套种福建青冈等12个造林树种对比试验,分析其胸径、树高、枝下高和冠幅的生长情况,表明在杉木林冠下生长比较好的树种有细柄阿丁枫、木荷和福建柏,可作为杉木林冠下造林的首选树种;生长较差的有酸枣、拟赤杨、檫树、厚朴、红豆树和福建青冈等,这些树种不适宜作为杉木林冠下造林树种,特别是福建青冈不宜在杉木林冠下造林,其在杉木林冠下的生长速度明显低于在全光照条件下。
The comparison experiments between the growth of Cyclobanopsis chungii and Cunninghamia lanceolata artificial forests were made.The results show that DHB growth of Cyclobanopsis chungii is extremely less than that of Cunninghamia lonceoloata but the former＇s height growth is much more than the latter＇ s.At the same time,the comparison experiments about interplanting Cyelobanopsis ehungii and other 12 species in Cunninghancia lanceolata forest were made.Their growths of DHB,height,and crown are analyzed.The results show that Altingia gracilipes,Sehima superba and Fokienia hodginsii can grow well under the crown of Cunninghamia lanceofata so that they can be afforested under Cunninghamia lanceofata as the fast-selected species.Such species as Choerospondias axillarts,AlmiphyUum fortunei, Sassofras tsumu,Magnolia officinolis,Ormosia xylocarpa and Cyclobanopsis chungii can＇t grow well.So they aren＇t good for interplanting under Cunninghamia lanceolata,especially,Cyelobanopsis chungii.And Cyelobanopsis chungii＇s growth is slower than under all illumination.
