施用生物有机肥对烤烟生长及香气物质含量的影响

Effects of applying bio-manure on growth and content of aroma in flue-cured tobacco

为提高烟草香气物质含量和降低施肥成本,通过田间试验,研究了在常规施肥不同数量基础上增施不同数量生物有机肥对烟草生物学性状及主要香气成分含量的影响。结果表明:1)施用生物有机肥的各处理对各项生长指标有不同影响,最高可使根体积增加37.56%,根鲜质量增加18.72%,株高增加59.15%,茎围增加6.67%,叶面积增加5.61%;2)加施生物有机肥、或同时适当减少常规化肥施用量能有效提高烟叶中性香气成分含量,有9种中性香气成分含量各处理均高于对照,最高可使苯乙醇增加733%;3)在所测定的27种中性香气成分中,有18种成分的含量均以T6最高,表明施用生物有机肥,特别是T6处理能有效提高烟叶的主要中性香气成分的含量。

Effects of applying bio-organic fertilizer in addition of conventional treatment on content of main aroma components were studied through field trials to improve content of aroma in tobacco and reduce cost of fertilizers.Results showed that 1） applying bio-organic fertilizer had different effects on each growth index,including root volume,fresh root quality,plant height,stem girth,and leaf area which were increased in maximum by 37.56%,18.72%,59.15%,6.67%,and 5.61%,respectively.2） applying bio-organic fertilizer with lower application of regular fertilizer effectively improved content of neutral aroma.The content of 9 aroma components was higher than that of control and the phenylethanol was increased by 7.33 times in maximum.3） Among 27 aroma components,18 attainted the highest content in treatment T6,which indicated that T6 treatment can effectively improve aroma content in tobacco.
