摘　　要：以半夏的年产量作为评价指标,不同施肥量作为试验方法,分析了氮肥、磷肥、钾肥施肥量对半夏年产量的影响,确定半夏肥料配备的最佳配比条件。结果表明,尿素、磷酸二氢铵、硫酸钾3种化肥中,氮肥对半夏产量的影响最为显著,其次是钾肥,对半夏产量影响最小的是磷肥;按氮、磷、钾肥3∶1∶1.8的比例施用化肥合计约45 kg/亩时,半夏产量最佳,产量可达370 kg/亩。The annual yield of Pinellia ternate was used as the evaluation index and the amount of fertilizerwas different.The effects of nitrogen,phosphorus and potassium fertilizers on the annual yield of Pinelliaternata were analyzed.The results showed that nitrogen fertilizer had the most significant effect on the yieldof Pinellia ternate,followed by potassium fertilizer.The effect of phosphorus fertilizer on Pinellia ternatayield was the lowest.The effect of nitrogen fertilizer on N,P,The proportion of1.8potassium fertilizerapplication of fertilizer total of about45kg/acre,Pinellia ternate yield best,yield up to370kg/acre.
