摘　　要：为了简化施肥程序,降低劳动强度,实现烟叶生产的节本增效,采用田间试验,在四川会东县调查研究了烤烟一次性施肥的应用效果。结果表明,一次性施肥烟株生长发育不仅与传统施肥相近,而且根系干重、活力和硝酸还原酶活性均增加。其中一次性施肥结合提苗肥硝酸钾20 kg/hm2,分3次追施效果最好,田间管理用工可节省27个/hm2,节本增效3 685.9元/hm2,烟叶化学成分也在适宜的范围内。因此,一次性施肥具有较大的推广应用价值。Streamlining fertilizer processes, reducing labor intensity and increasing economic benefit of tobacco-growing were the purpose of this research. The field experiment was conducted to study application effects of one-time fertilizer in Huidong tobacco growing area. The results showed that tobacco with one-time fertilizer grew normally and maintained higher root activity and NR vitality. The dry weight of roots also increased. One-time fertilizer with KNO3 at the rate of 20 kg/ha reduced labor 27 person/ha and increased 3 685.9 yuan/ha. The chemical components contents were more coordinated, all in appropriate range of quality tobacco It had great potential for popularization and application in Huidong tobacco growing area.
