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.
对杉木与8种伴生植物混合凋落物分解的研究表明，8种混合植物对杉木凋落物的分解均有不同程度的促进作用，其中福建观音座莲的促进作用最大，木荷则先有一定促进作用，后有较弱抑制作用。促进作用顺序为福建观音座莲＞杜茎山＞薛荔＞日本狗脊＞苎麻＞栲树＞黧蒴栲＞芒萁。杉木凋落物对木荷和黧蒴栲的凋落物分解有一定抑制作用，对栲树的凋落物分解有一定促进作用，但相互作用不显著。杉木与部分植物在混合分解过程中存在相互作用。因此，合理保护和恢复林下植物对于加快杉木人工林生态系统养分循环和维持土壤肥力具有重要意义。
