Abstract

To reveal characteristics of nutrients in leaching water at four different fertilizer levels, controlling with no fertilizer, half of the normal rate, normal rate with 1 125.0 kg/hm2 of urea and 2 250.0 kg/hm2 of compounded fertilizer, and one and half of the normal rate, a field experiment was conducted in Phyllostachys praecox stands. Leaching water was collected and analyzed from May to October in 2007. Results showed that there was a significant linear relationship between the amount of leaching water and the precipitation. The concentrations of different types of nitrogen and total phosphorous were increasing with growing of fertilizer rate, as well as the load of leaching loss. The monthly amount or concentration of all nutrients in leaching water gradually decreased from May to September but increased significantly in October, this trend was closely related to the amount of leaching water. The amount of nitrogen leaching from stands with treatments under half of the normal rate, normal rate and one and half of the normal rate were accounting for 4.22%, 425% and 4.54% of total fertilizer applied respectively, the correspondence data for phosphorus were accounting for 107%, 0.65% and 0.56% respectively.
