| Abstract: | Fertilizer application study on cluster redpepper was conducted by using saturated-D-optimum design.The average nutrition uptakes of the cluster redpepper are N 274kg/hm2,P2O5 57kg/hm2,K2O 265 kg/hm2,Ca 124kg/hm2,and Mg26kg/hm2 respecitvely when the yield is 3826kg/hm2.At the yield of 4767.2 kg/hm2,the highest profit,15131 yuan/hm2,is obtained.The ratio of output/input is 17.71:1.The optimum application rate of N is 281.lkg/hm2 and that of P2O5 is 82.lkg/hm2. |
