不同移栽方式对烟叶移栽环节及品质的影响

Effects of Different Transplanting Methods on Transplanting Stage and Quality of Tobacco

以云烟87为供试材料,研究了不同移栽方式对移栽烟苗井窖、移栽环节投入、长势情况、内在化学成分协调性、中性致香物质含量及烟叶产量的影响。结果表明,实施井窖移栽能有效解决烟苗深移栽问题,同时能降低烟农生产投入;井窖+覆杯罩移栽能解决揭膜难度大、地膜残留造成地膜污染的难题,且井窖+覆杯罩移栽烟叶长势强,内在化学成分协调,中性致香物质充足;井窖+覆杯罩移栽能增加烟农收益,主要是提高烟叶产量、产值、均价、上中等烟比例,产值较常规覆膜移栽提高3750元/hm^2,均价较常规覆膜移栽提高1.06元/kg。

Yunyan 87 was used as the test material,the effects of different transplanting methods on well pit,input of transplanting stage,growth situation,coordination of internal chemical components,content of neutral aroma-producing substances and yield of tobacco leaves were studied. The results showed that the pit transplantation could effectively solve the problem of deep transplantation of tobacco seedlings,and reduce the production input of tobacco farmers. Pit+cover cup covering transplantation could solve the difficult problem of film uncovering and film contamination caused by residual plastic film. Moreover,pit +cover cup covering transplanted tobacco leaves grew vigorously,the inherent chemical composition was coordinated,and neutral aroma substances were abundant. Pit+cover cup covering transplantation could increase the income of tobacco farmers,mainly by increasing the output value,average price and the proportion of upper and middle tobacco. The output value was 3 750 yuan/hm^2 higher than that of conventional transplantation,and the average price was 1.06 yuan/kg higher than that of conventional transplantation.
