    株行距、留叶数对烤烟品种KRK26主要经济性状的影响

    Effects of Planting Spacing and Leaf Number on Main Economic Characters of Flue-cured Tobacco KRK26

    • 摘要: 为探索KRK26在湖北省宜昌市的适宜栽培措施,进行了行距、株距、留叶数对KRK26的产质量影响的L9(34)正交试验.结果表明,行距对上中等烟比例、均价的影响达到极显著差异;株距对产量、产值、上等烟比例、上中等烟比例的影响达到极显著差异,对上部叶比例的影响达到显著差异;留叶数对产值的影响达到极显著差异. 在宜昌烟区,津引烤烟品种KRK26栽培的最优适宜组合为A3B2C2,即行距1.2 m、株距0.55 m、留叶数21~23片比较适宜.

       

      Abstract: In order to find out the suitable cultivation practices for KRK26, the flue-cured tobacco cultivar introduced from Zimbabwe, in Yichang, Hubei Province, the effects of row spacing, plant spacing and the number of leaves after topping on yield and main economic characters of the flue-cured tobacco variety KRK26 were studied with L9(34)orthogonal experiments. The results showed that row spacing had a highly significant impact on average price and the percentage of above-average grading leaves. Plant spacing had a highly significant impact on yield, output, proportion of high class leaves and above-average grading leaf percentage, and had a significant impact on the proportion of upper leaves. Leaf number had a highly significant impact on output. The appropriate cultivation measures of KRK26 include 120 cm of row spacing, 55 cm of plant spacing and 21-23 leaves in Yichang city of Hubei Province.
