Abstract: Aimed at the unreasonable use of chemical fertilizers in seedling land， the present research focused on the effect of different fertilization treatments on nitrogen and phosphorus runoff losses was carried out in Simingshan Town， Yuyao City， Zhejiang Province from April 26th to June 23rd， 2013， to provide theoretical basis for non\|point source pollution control in drinking water source areas. It was shown that concentrations of nitrogen and phosphorus in the first runoff after fertilizer application were higher than those in later runoff， especially in the runoff from broadcasting compound fertilizer treatment. The influence of different fertilization treatments on TN， NH+4\|N， TP， DRP runoff losses decreased in the order of broadcasting compound fertilizer＞spot application of compound fertilizer＞broadcasting controlled release fertilizer＞spot application of controlled release fertilizer＞CK. Concentrations of TN and TP in the runoff of spot application of compound fertilizer treatment were significantly lower than those in broadcasting compound fertilizer treatment. However， concentrations of TN and TP in the runoff between spot application of controlled release fertilizer treatment and broadcasting controlled release fertilizer treatment were close. Considering the environmental impact and cost， spot application of compound fertilizer and broadcasting controlled release fertilizer were two kinds of worth promoting fertilization ways in hilly seedling land.

Key words: controlled release fertilizer, seedling land, runoff, nitrogen and phosphorus loss
