摘　　要：为简化高效配方施肥,以芝麻(Sesamum indicum Linn.)品种鄂芝6号为试验材料,通过“3414”田间肥效试验研究了氮、磷、钾不同施肥水平对其产量和主要经济性状的影响。结果表明,氮、磷、钾不同施肥水平对芝麻产量均有不同程度的影响,以不同氮肥处理的影响最大。14个处理中以施尿素292.5 kg/hm2、过磷酸钙249.0 kg/hm2、氯化钾150.0 kg/hm2的处理(N3P2K2)产量最高,为1751.0 kg/hm2;施尿素195.0 kg/hm2、过磷酸钙124.5 kg/hm2、氯化钾150.0 kg/hm2的处理(N2P1K2)产量次之,为1682.0 kg/hm2;不施氮、磷、钾肥的处理(N0P0K0)产量最低,为1302.0 kg/hm2。N、P、K最佳配施比例为10∶2∶7。To get simple and efficient formula fertilization,sesame(Sesamum indicum Linn.)variety Ezhi No.6 was adopted to study the effect of different N,P,K fertilizers on sesame yield and yield-related traits by“3414”fertilizers application experiment.The results showed that the different levels of N,P,K have different effects on the yield of sesame,and the nitrogenous fertilizer had the highest effects.Among 14 treatments,the yield of treatment of 292.5 kg/hm2 urea,249.0 kg/hm2 superphosphate and 150.0 kg/hm2 muriate of potash kalium chloratum(N3P2K2)was the highest,and the yield was 1751.0 kg/hm2;The yield of treatment of 195.0 kg/hm2 urea,124.5 kg/hm2 superphosphate and 150.0 kg/hm2 muriate of potash kalium chloratum(N2P1K2)was the second,and the yield was 1682.0 kg/hm2;The yield of no fertilization treatment(N0P0K0)was the lowest,and the yield was 1302.0 kg/hm2.The optimum ratio of N,P and K is 10∶2∶7.
