育苗方式对烟叶生长及产质量的影响

Effects of Breeding Methods on Flue-cured Tobacco Growth,Yield and Quality

[目的]筛选适合粤北烟区的先进的育苗方式。[方法]采用田间试验的方法,研究漂浮育苗、湿润育苗、营养袋育苗处理对成苗期烟苗素质、烟株大田生长和烟叶产质量的影响。[结果]湿润育苗处理烟苗各项生理指标高于或显著高于营养袋育苗和漂浮育苗处理,湿润育苗处理烟苗移栽大田生育期合理,农艺性状表现好,产质量提高,化学成分更加协调。[结论]湿润育苗是一项适合粤北烟区的先进育苗方式。

[Objective] The aim was to screen out the advanced breeding way suitable for northern Guangdong tobacco area .[ Method] By using field experiment, effects of floating seedling, moist breeding, nutrition bag breeding on tobacco seedling quality, field growth, yield and quality of tobacco leaf were studied.[Result] In moist breeding treatment, physiological indexes of tobacco seedlings were higher or significant higher than that in floating seedling and nutrition bag breeding, the field growth period was reasonable, the agronomic characters were good, the yield and quality were improved, and the chemical composition was more harmonious.[Conclusion] Moist breeding is the advanced breeding way suit-able for northern Guangdong tobacco area .
