竹阔混交林分毛竹生产力的研究

Study on the Productivity of Phyllostachys pubescens Forest Mixed with Broadleaved Trees

福建省沙县梨树乡泉水峡村市坑10年生竹阔混交林毛竹生产力的研究结果表明：竹阔混交林具有较高的生产力和显著的经济效益，毛竹的平均胸径、平均竹高、平均竹秆重量蓄积分别比毛竹纯林的提高了9．8％、17．6％和48.7％；产竹材量和产鲜笋量分别比纯毛竹林增加36．3％和35．2％；立竹度、均匀度、整齐度、叶面积指数均比纯毛竹林的高．

The study on the productivity of Phyllostachys pubescens forest mixed with broadleaved trees showed that the mixed forest had higher productivity and economic benefit, compared with pure forest, the mean DHB, mean height and mean weight of culm increased by 9. 8%,17. 6% and 48. 7% respectively, the culm yield and shoot yield increased by 36. 3% and 35. 2% repectively, the density, evenness, uniform and ILA were all higher than pure forest.
