Dynamics of litterfall and its decomposition and nutrient return of shoot-used Dendrocalamus latiflorus in Mountainous areas of Fujian Province

Abstract

Abstract: This paper studied the dynamics of nutrients in the litters of shoot-used Dendrocalamus latiflorus planted in Nanjing State-owned Forest Farm of Fujian Province.The results showed that the litterfall as well as its nutrient concentration and return varied obviously with seasons,and had a double-peak curve change.The weight loss during litter decomposition was very fast at first,and then slowed down.There was a negative exponent correlation between remained weight and decomposition time.During decomposition,the concentrations of N and P in litter showed a trend of increase-decrease-increase,while the K loss was intensive at the early stage,gently at mid-stage,and slight at late stage.

Key words: Dendrocalamus latiflorus, Mountainous area, Litter, Nutrient
