不同耕作方式对烤烟生长及内在品质的影响

Different cultivation methads impact on growth and intrinsic quality of flue-cured tobacco

为探讨东部丘陵区烤烟抗旱耕作技术,利用烤烟品种吉烟9号为材料,设置6个处理进行田间试验.结果表明,在农艺性状、物理性状和经济性状上,深耕+地膜,垄下深松+地膜,传统耕作+地膜3个覆盖地膜的处理优于深耕,垄下深松和传统耕作3个不覆盖地膜的处理,覆盖地膜的处理间进行比较,深耕+地膜>垄下深松+地膜>传统耕作+地膜,不覆盖地膜的处理间进行比较,深耕>垄下深松>传统耕作.在化学成分上,深耕、深耕+地膜、垄下深松的各项指标均优于其它处理.深耕+地膜,垄下深松+地膜,传统耕作+地膜,深耕,垄下深松的主要经济性状相对于传统耕作的增幅依次减小,深耕+地膜、垄下深松+地膜的香气成分的种类比较丰富,有正面影响的成分种类也较多.综合来看,深耕+地膜最好,垄下深松+地膜次之.

In order to study the drought-resistant cultivation technique of flue-cured tobacco in easten hilly area,selecting flue-cured tobacco variety Jiyan9 as the material,set six treatments for field experiment.The results showed that the agronomic characters,main economic characters,physical properties of deep tillage＋plastic film,subsoiling＋plastic film,conventional tillage＋plastic film（plastic film mulching） were better than deep tillage,subsoiling,conventional tillage（no plastic film mulching）.Comparing plastic film mulching treatments,deep tillage＋plastic film was highest,followed by subsoiling＋plastic film and conventional tillage＋plastic film.Comparing on plastic film mulching treatments,deep tillage was highest,followed by subsoiling and conventional tillage.On the main chemical components,all indexes of deep tillage,deep tillage＋plastic film,subsoiling were better than other treatment.The increasing range of plot yield,yield,output value,high grade leaves and average leaf price of deep tillage＋plastic film,subsoiling＋plastic film,conventional tillage＋plastic film,deep tillage,subsoiling minished in order compared with conventional tillage.The aroma component＇s species of deep tillage and subsoiling＋plastic film is relatively rich,the species of front composition is more.In general,the treatment of ＋plastic film is best,following by subsoiling＋plastic film.
