Runoff plots experiment was conducted to study the effects of recommended fertilization,recommended fertilization with split-applied fertilization and recommended fertilization with planting grass on the output of runoff,nitrogen and phosphorus,form of nitrogen and phosphorus.Results showed that recommended fertilization with planting grass and recommended fertilization with split-applied fertilization significantly reduced runoff losses 38.43% and 26.51% compared with the conventional fertilization.Rainfall intensity is the main driving factor for the loss of nitrogen and phosphorus with more than 96% of nitrogen lost and 98% of phosphorus lost happened during the heavy rain and torrential rain.Dissolved nitrogen and particle phosphorus other than fertilizer application were the main loss forms of nitrogen and phosphorus in Danjiangkou Reservoir orchard.The loss of total nitrogen,dissolved total nitrogen and dissolved total phosphorus were deceased significantly by increasing the frequency of fertilizer application,and planting grass can effectively reduce the loss of total phosphorus and particle phosphorus.The loss of 35.96% total nitrogen was decreased by increasing the frequency of fertilizer application while the loss of 59.31% total phosphorus were reduced significantly by planting grass,compared with the conventional fertilization.
