烤烟新品系HY-9-7经济施肥技术研究

Study on Economic Manuring Technique of New Strain HY-9-7 of Flue-cured Tobacco

对烤烟新品系HY-9-7经济施肥技术研究表明:在0～11 kg氮用量范围内,旺长期烤烟生理活性随用肥量提高而增强;11 kg氮用量水平烤烟长势强、产质量较高,但中、上部叶烟碱含量明显提高,烟叶化学成分协调性明显下降;9 kg氮用量水平,追肥浇施、干施结合,烤烟产质量水平稍次于11 kg氮用量水平,中上部烟叶化学成分协调性好。

Physiological activity was escalated along with increasing manure dosage in peak season of flue-cured tobacco with 0- 11 kg nitrogen dosage scope. The growing posture of flue-cured tobacco was better and the yield-quality was higher, yet, the nicotine content of cutters and upper leaves were improved markedly, and the chemical components harmony of tobacco leaves was declined evidently With 11 kg nitrogen dosage treatment. While flue-cured tobacco yield- quality level was slightly lower and the chemical components harmony of cutters and upper leaves were better with 9 kg nitrogen dosage than those with 11 kg nitrogen dosage treatment, with additional manuring of manure dissolved in water combined with manuring directly treatment.
