霜冻后不同处理对翠碧一号烟叶产量及质量的影响

Effects of Different Treatments After Frost on Yield and Quality of Cuibi 1 Tobacco Leaves

对遭受霜冻的烟叶采用培育倒3杈、削茎留底杈、自然生长等3种方式进行处理,研究不同处理方法对翠碧一号烟叶农艺性状、烟叶品质、烟叶产量及产值的影响。结果表明:采用培育倒3杈的方式,其产值高于自然生长处理,但烟叶外观品质不如自然生长处理;产量与上等烟比例等性状二者差异不显著。综合来看,如果翠碧一号烟叶团棵期遭受霜冻,受冻较轻的烟株采用自然生长的方式进行处理,受冻较重的烟株采用培育倒3杈的方式进行处理,不建议采用削茎留底杈的处理方式。

The frosted tobacco leaves were treated by three methods(cultivating inverted 3 branches,cutting stem and remaining bottom branch,natural growth),and the effects of different treatment methods on the agronomic properties,tobacco quality,tobacco yield and output value of Cuibi 1 were studied.The results showed that the output value of cultivating inverted 3 branches was higher than that of natural growth treatment,but the appearance quality of tobacco leaves leaves was lower than that of natural growth treatment;there was no significant difference in yield and the proportion of top-grade tobacco between cultivating inverted 3 branches and natural growth treatment.In general,if Cuibi 1 tobacco leaves suffer from frost during the cluster stage,the ones with light frost shall be treated by natural growth,and the ones with heavy frost shall be treated by cultivating inverted 3 branches,and the treatment of cutting stem and remaining bottom branch is not recommended.
