摘要:1997~1998年在广东省五华县的紫色土田进行了烤烟优质高产施肥试验。结果表明,在一定的氮磷施用量条件下,烤烟的产量、质量及产值都是随着施钾比例的提高而提高。在一定的配比下,烤烟的产量及产值在施氮165 kg/hm2以下均随施氮量的增加而提高;均价和优级烟率以中等氮水平(135 kg/hm2)的为最高。本文还提出烤烟的最佳施肥方案。

Abstract: A experiment was conducted on fertilization for achieving high quality and high yield of flue-cured o in the purple soil in Wuhua, Guangdong from 1997 to 1998. Results show that under the condition of a certain application rate of P and N, the yield, the quality and the output value of flue-cured o are increased with the increase in the proportion of K in fertilizers. At a certain cooperative application rate of P and K, the yield and the output value of flue-cured o are raised with the rise of N application rate and less than 165 kg/hm2. But the average price and the rate of fine quality are highest when the application rate is 135 kg/hm2. Also, the optimum fertilization sch
