In order to explore the effects of phosphate fertilizer types and input rates on yield，dry matter accumulation and phosphate fertilizer utilization efficiency of pepper in greenhouse，the theoretical and practical basis for the phosphate fertilizer efficient utilization of pepper in greenhouse was provided.A field experiment was carried out using “Anhui pepper 101” as test crop.No phosphorus application was used as control (CK)，and two phosphate fertilizer types were set up (ordinary diammonium phosphate and coated diammonium phosphate).Four phosphorus fertilizer input rates were P2O5 30 kg/hm² (P30)，60 kg/hm² (P60)，90 kg/hm² (P90)，120 kg/hm²(P120)，making a total of 9 treatments.Mainly studied the response of pepper yield，dry matter accumulation，phosphorus absorption and phosphorus fertilizer utilization to different types and amounts of phosophorus fertilizer.The results showed that the yield，stem，leaf，fruit dry matter and phosphorus accumulation of pepper increased with the increase of phosphorus application under the condition of ordinary diammonium phosphate，and P120 treatment was the highest.With the application of diammonium phosphate coated with polyurethane，the yield，dry matter of leaves，fruit and phosphorus accumulation of capsicum pepper showed a trend of first increasing and then stabilizing with the increase of phosphorus application amount，and P90 treatment was the highest.Under the treatments of P30 and P90，the application of diammonium phosphate coated with polyurethane increased the yield significantly by 10.1% and 7.8% compared with ordinary diammonium phosphate.Under the treatments of P30 and P60 and compared with the ordinary diammonium phosphate，the pepper fruit and aboveground dry matter accumulation of applying coated diammonium phosphate significantly increased by 10.1%，26.6% and 6.7%，18.8%，fruit and aboveground phosphorus absorption increased by 13.9%，27.0% and 10.6%，21.9%，phosphorus use efficiency by 11.5% and 13.8%，the phosphorus fertilizer agronomy utilization rate by 43.7% and 32.0%，the phosphorus partial productivity by 10.1% and 9.4%，respecively.Under the conditions of this study，coated diammonium phosphate can promote the growth and development of pepper and improve the utilization rate of phosphorus.The region’s best coated applying diammonium phosphate amount is P2O5 86.9 kg/hm²。
