摘要/Abstract

摘要： 通过对杉木与9种伴生植物凋落物混合分解特征比较研究表明,8种植物对杉木凋落物的分解均有不同程度的促进作用,其中观音座莲对杉木凋落物分解的促进最大,而木荷对杉木凋落物分解的影响则表现出先有一定程度的促进而后又有微弱的抑制作用.促进大小表现出观音座莲＞杜茎山＞三龙爪＞狗脊＞苎麻＞丝栗栲＞闽粤栲＞芒萁.杉木凋落物反过来对木荷和闽粤栲凋落物有一些抑制作用,而对丝栗栲则有一些促进作用,但这种相互作用未达到显著差异水平.说明杉木与某些伴生植物种类的凋落物在混合分解过程中存在着相互作用的现象.因此,合理保护和恢复林下植物对加快杉木人工林生态系统的养分循环和地力维护具有重要的意义.

Abstract: Studies on the decomposition of mixed litter between Chinese fir and 8 accompanying plant species showed that the decomposition of Chinese fir litter was promoted to different degrees by 8 mixed plant species, in which Angiopteris fokiensis had the greatest effect,while Schima superba had certain promotion first,but then,weak inhibition. The order of promotion was Angiopteris fokiensis>Maesa japonica>Ficus simplicissima>Woodwardia japonica>Boehmeria nivea>Castanopsis fargesii>Castanopsis fissa>Dicranopteris dicotoma.Chinese fir litter had a certain inhibition to litter decomposition of Schima superba and Castanopsis fissa, and certain promotion to litter decomposition of Castanopsis fargesii,but the interactions were not significant.There existed an interaction between Chinese fir and some plant species in the course of mixed decomposition. Therefore,rational protection and restoration of understory plant was important to fasten nutrient cycling of Chinese fir plantation ecosystem and to maintain soil fertility.
