采用随机区组试验,研究了不同移栽期对‘云烟85’烟叶质量风格特色的影响.结果表明:当地提早移栽的烟叶外观质量总体上比对照烟叶好,表现为烟叶颜色橘黄,结构疏松,成熟度成熟,身份较适中,油分较足,色度较均匀、饱满.特别是中上部烟叶,表现出随着当地移栽期的提前,烟叶外观质量逐渐变好的趋势.推迟移栽的烟叶外观质量均比对照烟叶差.试验中随着当地移栽期的提前,‘云烟85’烟叶香型呈现由浓香逐步向清香转变的趋势,烟叶甜感呈现由焦甜逐步向清甜转变的趋势;烟叶香气质变好,香气量更足,杂气变轻,烟气变细腻,浓度增大,劲头更适中,刺激性变小,余味变好,感官质量综合得分增高.不同移栽期处理对烟叶常规化学成分含量的影响不明显.方差分析表明,4个移栽期处理在烟叶感官质量特征各指标上的差异均达到显著或极显著水平,在烟碱、总糖、还原糖、钾和氯含量的差异均不显著.
The effects of different transplanting periods on the quality and style of ’Yunyan 85’ were studied by randomized block experiments.The results showed that the appearance quality of the local earlier transplanted tobacco was better than that of the control tobacco, showing orange color and loose structure , Maturity maturity, more moderate identity, more oil than full, more uniform color, full, especially in the upper leaves, showing the local transplanting period ahead of the appearance of tobacco leaf quality becomes better trend. The appearance quality of tobacco leaves were worse than that of the control tobacco leaves.With the advance of local transplanting period, the flavor of ’Yunyan85’ showed a gradual change from fragrance to fragrance, and the sweetness of tobacco showed a gradual shift from sweetness to sweetness The flavor of tobacco improved, the amount of aroma is more adequate, the less volatile gas, flue gas becomes delicate, the concentration increases, the momentum more moderate, less irritating, the aftertaste becomes better, the sensory quality comprehensive score increased.Different transplanting period The results showed that there was no significant difference in the contents of conventional chemical constituents from tobacco leaf.Analysis of variance showed that the differences of sensory quality traits among the four transplanting treatments reached significant or extremely significant levels, and the nicotine, total sugar and reducing sugar , The difference of potassium and chlorine content is not significant.
