对K 326进行不同施肥量处理后发现,烟叶叶绿素、可溶性蛋白含量和采收天数随施肥水平的升高而增大,随着成熟度的递进而降低;叶面积、产值量随施肥水平的升高和成熟度的递增先升高后降低;产值量和化学成分分析发现,同部位烟叶以适肥处理为最好,其次为过肥处理和欠肥处理。结果表明,适肥处理有利于形成良好的烟叶品质。

Experiment of different fertilization rate to tobacco K326 showed that contents of chlorophyll,soluble protein in tobacco leaf and harvest days were increased with the increment of fertilization rate ,but decreased with the advancement of maturing process. Along with increasing of fertilization rate and advancing of maturing process,leaf area and the output value were increased at first and then decreased. Analyses on output value and chemical component of the same rank tobacco leaf showed that suitable fertilization was better than over-fertilization and lower-fertilization. Suitable fertiliz...
