摘　　要：以吉林延边主栽烤烟品种吉烟9号为试验材料,采用田间小区试验,研究了不同耕作措施对烟田水分、烤烟生长及烟叶产量品质的影响。结果表明:(1)移栽20 d后,垄下深松处理(T1和T2)烟田各土层水分含量均高于常规起垄(CK),移栽40 d和60 d后,50 cm以上各土层含水量均是垄下深松结合揭膜后中耕培土处理(T2)>对照>垄下深松;(2)垄下深松处理(T1)旺长期烟叶氮素和磷素含量高于对照,垄下深松结合揭膜后中耕培土处理(T2)团棵期与旺长期烟叶氮素和磷素含量高于对照,且烟叶钾素含量均随着生育时期的推进呈下降趋势;(3)T1和T2可不同程度促进烤烟生长,增大叶面积,增产增质,其中垄下深松结合揭膜后中耕培土处理烤烟经济性状各项指标和致香物质总量最高,化学成分较为协调,产量和产值分别较对照提高310 kg/hm2和5997.9元/hm2。Effects of different tillage practices on field soil moisture content, flue-cured tobacco growth, leaf yield and quality were studied by field experiments with Jiyan 9 as material. Results showed that： （ 1 ） soil moisture content of deep tillage under ridge （DTR） treatment （ T1 and T2 ） was higher than that of conventional tillage treatment （CT） （CK） 20 days after transplanting. The sequence of upper 50cm soil moisture content was DTR ＋ plastic film uncovered （PFU） ＋ cultivator （ DTR ＋ PFU ＋ C） （T2） 〉 CK 〉 DTR 40 and 60 days after transplanting; （2） N and P con- tents in tobacco leaf with DTR treatment were higher than that of CK during fast growth stage, while that of T2 is higher in both of resettling growth stage and fast growth stage. K content decreased with prolonged growth stages. （3） Com- pared with CK, T1 and T2 treatments can promote growth, enlarge leaf area, and improve quality and yield. T2 treat- ment resulted the highest total aroma and economic characteristics index and the best harmony of chemical components a mong all treatments. Yield and economic value increased by 310 kg/hm2 and 5997.9 RMB/hm2.
