摘要
为了明确深耕及深耕配合秸秆还田和绿肥翻压对植烟土壤呼吸及烤烟生长的影响,以中烟100为研究材料,通过设置不同的耕作方式处理,分析了深耕对烟田土壤呼吸速率及其调控因子、烤烟生长发育、烤后烟叶化学成分含量和感官质量的影响。结果表明:深耕及深耕后翻压绿肥或秸秆还田能够明显提高烟田土壤的呼吸速率,增加烤烟在圆顶期的植株总干物质积累量;深耕及深耕+绿肥/秸秆还田处理能明显增加烤后中上部烟叶的中性致香物质总量;常规耕作+绿肥处理能明显提高中部叶的类西柏烷类降解产物含量;在中上部烟叶的感官评吸得分上,常规耕作对照及常规耕作配合翻压绿肥或秸秆还田处理都高于深耕各处理。
In order to clarify the effects of deep tillage,deep tillage combined with the application of straw returning and green manure conversion on soil respiration and flue-cured tobacco growth,Zhongyan 100 was used as the research material,and different tillage methods were set up.The effects of deep tillage on tobacco soil respiration rate and its regulating factors,flue-cured tobacco growth and development,chemical composition and sensory quality were analyzed.The results showed that deep tillage and green manure conversion or straw returning after deep tillage could significantly increase the respiration rate of the tobacco field soil and the total dry matter accumulation of the flue-cured tobacco plants in the dome period.Deep tillage and deep tillage+green manure/straw returning to the field could significantly increase the total amount of neutral aroma substances in the middle and upper tobacco leaves after curing.Conventional cultivation+green manure treatment could significantly increase the content of cembranes degradation products in the middle leaves.However,in the smoking scores of the middle and upper tobacco leaves,conventional tillage treatment and conventional tillage combined with green manure or straw returning treatment were higher than deep tillage treatments.
