以云烟87为供试品种，采用双因素裂区试验，研究了不同移栽期、覆盖方式对烤烟品质相关的外观质量、物理特性、化学成分、香气成分、感官质量和肥料利用率等指标的影响。结果表明：同一覆盖处理下， N、P肥料利用率随移栽期推迟呈现先增高后降低趋势；烟叶外观质量6项指标以移栽期5月1日、5月6日地膜覆盖处理表现较好；随移栽期推迟，烟叶长度、宽度、单叶重和叶质重有所增加，厚度、含梗率和平衡含水率有所降低；烟叶化学成分各项指标整体表现为移栽期5月6日、5月11日的稻草覆盖和地膜覆盖处理较为适宜；随移栽期推迟，烟叶美拉德反应产物、苯丙氨酸类和类胡萝卜素类总量呈现降低趋势，新植二烯含量有所增加，类西柏烷类降解产物无明显变化规律；感官质量总分随移栽期推迟呈现出先升高后降低趋势；5月6日为重庆烟区烟苗移栽的最佳时期，5月1日～5月11日为重庆烟区适宜移栽时期。
以雲煙87為供試品種，採用雙因素裂區試驗，研究瞭不同移栽期、覆蓋方式對烤煙品質相關的外觀質量、物理特性、化學成分、香氣成分、感官質量和肥料利用率等指標的影響。結果錶明：同一覆蓋處理下， N、P肥料利用率隨移栽期推遲呈現先增高後降低趨勢；煙葉外觀質量6項指標以移栽期5月1日、5月6日地膜覆蓋處理錶現較好；隨移栽期推遲，煙葉長度、寬度、單葉重和葉質重有所增加，厚度、含梗率和平衡含水率有所降低；煙葉化學成分各項指標整體錶現為移栽期5月6日、5月11日的稻草覆蓋和地膜覆蓋處理較為適宜；隨移栽期推遲，煙葉美拉德反應產物、苯丙氨痠類和類鬍蘿蔔素類總量呈現降低趨勢，新植二烯含量有所增加，類西柏烷類降解產物無明顯變化規律；感官質量總分隨移栽期推遲呈現齣先升高後降低趨勢；5月6日為重慶煙區煙苗移栽的最佳時期，5月1日～5月11日為重慶煙區適宜移栽時期。

Using Yunyan 87 as tested cultivar , the effects of different transplanting periods and mulching methods on appearance quality , physical properties , chemical component , aroma components , sensory quality and fertilizer use efficiency of flue -cured tobacco were studied by two -factor split plot experiment .The re-sults showed that fertilizer use efficiency of N and P under the same mulching method increased at first and then decreased with the delay of transplanting period .The six indicators of leaf appearance quality performed better under plastic film mulching when transplanting on May 1 and May 6 .With the delay of transplanting pe-riod, the leaf length and width , weight per leaf and leaf specific weight increased , while the leaf thickness , stem percentage and equilibrium moisture content decreased .The indicators of tobacco leaf chemical compo-nent were more appropriate under plastic film mulching and straw mulching when transplanting on May 6 and May 11.With the delay of transplanting period , the contents of Maillard reaction products , phenylalanine and carotenoids in tobacco leaves showed a decreasing tendency , the content of neophytadiene increased , and the content of degradation products of cembranoids had no obvious variation .The sensory quality increased at first and then decreased with the delay of transplanting period .The best transplanting time was May 6 and the suit-able transplanting period was May 1~May 11 in Chongqing tobacco growing area .
