title: [Dynamics of litterfall and its decomposition and nutrient return of shoot-used Dendrocalamus latiflorus in Mountainous areas of Fujian Province].
abstract: This paper studied the dynamics of nutrients in the litters of shoot-used Dendrocalamus latiflorus planted 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.
