天鹰椒吸肥特点及氮、磷肥应用效果

The characteristics of cluster redpepper in nutrition uptake and its response to N and P fertilizers

摘要: 天鹰椒运用饱合D-最优设计试验方案的N、P肥料试验结果表明，当天鹰椒产量为3826kg／hm² 时，平均养分吸收量N 为274kg／hm²、P₂O₅57kg／hm²、K₂0 265kg／hm²、Ca 124kg／hm²、Mg26kg／hm²，天鹰椒N、P肥配比适宜可获得较高效益，适宜N、P施肥量N 为281．1kg／hm² 、P₂0₅82．1kg／hm² ，最高产量可达4767．2kg／hm² ，效益达15131元／hm² ，产投比为l7．71：1。

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 ，P₂O₅57kg／hm² ，K₂O 265kg／hm²，Ca 124kg／hm²，and Mg 26kg/hm² respecitvely when the yidd 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 281．1kg／hm² and that of P₂O₅ is 82．1kg／hm² ．
