不同栽培方式与钾肥使用方法对烤烟产质量的影响

Effect of both cultivating method and potassic fertilizer on the quality of flue-cured tobacco

通过分析经济性状、原烟外观质量、化学成分和物理特性的变化,研究不同栽培方式与钾肥使用方法对烤烟产质量的影响.结果表明,低起垄2次培土成垄,钾肥50%作基肥起垄时条施、20%掏苗时追施、栽后25～30 d用2%～3%速溶硫酸钾进行根外追肥、40～45 d用2%～3%的速溶硫酸钾进行第2次根外追肥的表现为经济性状良好,原烟外观质量好,化学成份、物理特性最协调.

Stated the effect of both cultivating method and potassic fertilizer on the quality of flue-cured tobacco through the economic traits,tobacco appearance quality and both chemical compositions and physical characteristic.The results showed that when the ridges were hilled up,they were applied 50% of potassic fertilizer as the basic fertilizer,applied 20% of it when they sprouted out,after 25~30 days supplied 2%~3% of instant potassium sulfate outside of the roots,after 40~50 days they were supplied again.As a result,the tobacco leaves had nice economic traits and appearance.And also appeared balanced chemical compositions and physical characteristic.
