福鼎槟榔芋“3414”肥料效应及推荐施肥量研究

应用“3414”田间肥料试验设计对福鼎槟榔芋进行肥料试验，并建立了肥料效应函数，确定最佳施肥量，结果表明：对槟榔芋产量因子的影响效应大小依次为N、K2O、P2O5，即氮效果最好、增产量最大、纯收益最高；钾肥效益次之，施磷肥增产效果不明显。根据肥料效应函数，结合当地槟榔芋生产实际，确定最佳氮磷钾施肥推荐用量：氮343．3kg／hm^2、磷108．0kg／hm^2、钾282．0kg／hm^2，氮磷钾比例为1：0．31：0．82，最佳产量为22814．6kg／hm^2。...

Clocasia escallenta; ＂3414＂ test; Fertilizer efficiency; Recommended fertilization amount
The ＂3414＂ test was conducted to study the fertilizer efficiency and determine the best fertilization amount for Clocasia escallenta Schott in Fuding. The results showed that the effect of N, P, K fertilizer on the yield components of Clocasia escallenta was in the order of N 〉 K20 〉 P205. Namely the application of N fertilizer had the best efficiency, and could obtain the highest yield in- crease and the highest net income; followed by the application of K fertilizer; the application of phosphorus fertilizer had no significant yield - increasing effect. According to the established function of fertilizer efficiency and the local production practice of Colcasia escallents, the best recommended fertilization amount combination was determined as follows： N 343.3 kg/hm^2, P 108.0 kg/hm^2, K 282.0 kg/hm^2,
