%X In order to control the agricultural non-point source pollution and to improve the water quality of Peiyan River effectively,release of soil N,P applied with different fertilizers was studied under simulated rainfall conditions.The soils were immersed for a short time(7 d) under conditions(1) without changing water to simulate static rainwater immersion and(2) changing water every day to simulate continuous rainfall.The results showed that the nutrient preserving capability of paddy field was the best,therefore paddy field should be fertilized with base fertilizer;those of orchard soil and forestland were inferior to that of paddy field,therefore the fertilization method of multiple top dressings with small amount should be adopted.Ammonium sulfate and ammonium chloride should be used as top dressing,while urea,ammonium carbonate should be used as base fertilizer.
