摘要
通过对杉木观光木混交林杉木与纯林杉木生长特性的比较分析 ,结果表明 :10a生前混交林杉木与纯林杉木树高生长比较接近。 10a生后直至 2 7a生混交林杉木树高生长始终大于纯林杉木。混交林中杉木在与观光木的竞争中始终处于优势地位 ,因此它的胸径、材积生长始终比纯林杉木大。 4~
The differences in growth process of Chinese fir between Chinese fir\| Tsoongiodendron odorun mixed plantation and pure Chinese fir plantation were studied. The height increment of Chinese fir in the mixed plantation was similar to that in the pure Chinese fir plantation before age 10. The height increment of Chinese fir in the mixed plantation was always greater than that in the pure Chinese fir plantation from age 10 to age 27. As the Chinese fir in the mixed forest took the predominant status over the Tsoongiodendron odorun, its DBH and volume increment were always greater than those of Chinese fir in pure Chinese fir plantation. Competitions among Chinese fir trees in the pure Chinese fir plantation were intense from age 4 to age 11.
