Decomposition interaction of mixed litter between Chinese fir and various accompanying plant species

Abstract

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.

Key words: Chinese fir, Accompanying plant, Litter, Mixed decomposition, Interaction
