烤烟优质高产施肥技术研究初报

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／ｈｍ~２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／ｈｍ~２）的为最高。本文还提出烤烟的最佳施肥方案。

Study on Fertilization for High Quality and High Yield of Flue-cured Tobacco

A experiment was conducted on fertilization for achieving high quality and high yield of flue-cured tobacco 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 tobacco 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 tobacco are raised with the rise of N application rate and less than 165 kg/hm~2. But the average price and the rate of fine quality are highest when the application rate is 135 kg/hm~2. Also, the optimum fertilization scheme is put forward in this paper.
