不同模式杉阔混交对林木生长的影响

摘要

通过对几种杉阔混交模式的试验研究，结果表明：杉木＋枫香和杉木＋木荷2种混交林与杉木纯林比较，在树高生长方面有极显著差异，其中以杉木＋枫香混交模式生长最好，为8．47m，杉木＋木荷模式次之，为7．93 m。杉阔混交对促进杉木林的健康生长有着非常大的作用。%Several modes for Chinese fir-and-broad-leaved mixed forest were studied .Result shows that :two kinds of mixed forest (Cunninghamia lanceolata+ Liquidambar formosana & Cunninghamia lanceolata + Schima super-ba) were compared to pure forest of Cunninghamia lanceolata;there are significant differences in height growth ,a-mong which the growth of mixed mode (C .lanceolata + L .formosana) is the optimal ,being 8 .47 m ,followed by C .lanceolata+ S .superba ,being 7 .93 m .Chinese fir-and-broad-leaved mixed forest has a significant role to promote healthy growth for C .lanceolata .
