“晟绿丰”药肥对烤烟产质量的影响

目的]为了研究"晟绿丰"叶面肥对烟叶产质量的影响。方法]以云烟85为研究材料,设晟绿丰150倍液、晟绿丰300倍液、晟绿丰450倍液、病毒必克500倍液和清水对照5个处理,研究施用晟绿丰对烤烟农艺性状、产值、产量、烟叶化学成分和内在品质的影响。结果]施用晟绿丰烟株在株高、茎围、叶片数及最大叶面积等农艺性状上与清水处理间差异不显著。施用晟绿丰,烟叶的产量、产值、均价、上中等烟率均略好于清水处理。施用晟绿丰使烟叶烟碱、总糖、还原糖略有增加,总氮、钾、氯、蛋白质含量略有降低,并使烟叶香气质、香气量、吃味和杂气等略有改善。结论]小区和大田试验表明晟绿丰对烟草生长无毒害作用。

A Preliminary Report on the effects of Medicine Fertilizer Shenglufeng on the Yield and Quality of Flue-cured Tobacco

The aim of the research was to study the effects of leaf fertilizer Shenglufeng on the yield and quality of flue-cured tobacco.With Yunyan 58 as research materials,5 treatments including Shenglufeng 150 fold liquid,Shenglufeng 300 fold liquid,Shenglufeng 450 fold liquid,Ribaririn 500 fold liquid and clean water(CK) were set up to study the effects of applying Shenglufeng on the agronomic traits and yield and output value of flue-cured tobacco,chemical constituents and internal quality of tobacco leaves.Some agronomic traits of tobacco plants including plant height,stem girth,leaf number,the maximum leaf area in the treatments of applying Shenglufeng had no significant difference with that in clean water treatment.The yield,output value,average price and the ratio of high-middle grade leaves of tobacco leaves in the treatment of applying Shenglufeng was all slightly better than that in clean water treatment.Applying Shenglufeng could increase tobacco nicotine,total sugar and reducing sugar slightly,and reduce total N,K,Cl and protein content slightly,and improve aroma quality,aroma volume,flavor and offensive odor of tobacco leaves.Plot test and field test showed that Shenglufeng had no harmful effect on tobacco growth.
