不同留杈部位对龙川江流域早花烟株主要农艺性状与经济性状的影响

Effects of Different Remaining-branch Position on the Main Agronomic and Economic Characters of Early Flowering Flue-cured Tobacco in Longchuanjiang Basin

采用随机区组法,进行了不同部位留杈对烤烟红花大金元早花烟株产质量的影响试验。结果表明,高杈处理(杈位2)的主茎高、杈烟高、杈烟叶片数、单株留叶数、产量和产值最高。由此可见,高杈处理(杈位2)更有利于杈烟良好生长,提高烟叶产量和产值。

Using randomized block method,the effects of different remaining-branch position on yield and quality of flue-cured tobacco Honghuadajinyuan were studied.The results showed that the height of main stem, the height of remaining-branch, the leaves per plant,yield and output value of the high remaining-branch treatment （the remaining-branch position 2）were the highest.So the treatment of the high remaining-branch （the remaining-branch position 2）was more favorable for good growth on the remaining-branch, and could increase tobacco yield and output value.
