施肥比例对烟草产量和品质的影响

Effects of Different Fertilization Ratios on Yield and Quality of Tobacco

试验采用联合国粮农组织(FAO)"3414"试验方案,稍作修改,研究不同施肥比例对烟草品质的影响。结果表明:氮磷钾施肥比例是影响烟叶品质和产量的重要因素。试验条件下产量最高的是MN3P2K2处理,产量达2 320.8 kg/hm2,产值最高的是MN1P1K2处理,为29 489.1元/hm2,均价最高的是MN1P2K1处理,达14.67元。最佳经济施肥量N为175.2 kg/hm2,P2O5为52.1 kg/hm2,K2O为278.3 kg/hm2,最佳产量为2 059.5 kg/hm2。

In order to study the effects of different fertilization rat ios on quality of tobacco, the experiment using slightly modified ＂3414＂ pilot program based on the ＂3414＂ pilot program made by Food and Agriculture Organization of the United Nations （FAO）. The results showed that the fertilization ratio of N, P and S is an important factor that impacting the quality and yield of tobacco leaves. Under the experimental conditions, the treatment of MN3P2K2 had the highest yield （2 320.8 kg/hm2）, the treatment of MN1P1K2 had the highest output value （29 489.1 yuan/hm2）, and the treatment MNIP2K1 had the highest average price （14.67 yuan）; the most economic fertilizer rate is 175.2 kg/hm2 in N fertilizer, 52.1 kg/hm2 in P205, and 278.3 kg/hm2 in K20; with the most economic fertilizer rate, the best yield reached 2 059.5 kg/hm2.
