摘要
多点联合正交试验结果表明,品种、留叶数、施肥量、追肥日期等因子对烟叶化学成分都有一定程度的影响,其中施肥量对总糖、总氮、蛋白质、钾含量的影响居第1位,品种对烟碱含量的影响居第1位.采用本研究I报所提出的组合模式进行栽培,不仅可以获得适宜的产量.优良的外观质量,而且可以提高烟叶的品质,实现优质适产高效益的目标.
A 2-years (1989～1990) study was couducted to determine the effect of cultural factors on the chemical characteristics of flue-cured tobacco (Nicotiana tabacum L.) grown in Hunan Province. Cured samples were analysed. The results iudicated that rate of apllication had a very great iufluence on the chemical composition of the tobacco.when the optimal combination of agronomic measures which was suggested in No I Report of the present study was adopted,the suitable and harmonious chemical composition would have been obtained.
