不同苕子绿肥翻压模式对烤烟产量和品质的影响

[目的]揭示苕子绿肥翻压对烤烟产量和品质的影响。[方法]以云烟87为材料,采用苕子绿肥与无机肥配施的方法,连续2年研究不同生物量的苕子绿肥翻压对烤烟产量和品质的影响。[结果]苕子绿肥翻压能显著提高烤烟的产量,其产量随绿肥翻压量的增加而增加。2006年处理④烤烟产量比处理③增加了2.8%,比对照增加了10.7%。2007年处理④的产量比对照增加了22.74%。各处理初烤后,各部位烟叶中总糖和还原糖含量均随苕子绿肥翻压量的增加而增加。烟叶中总氮、烟碱的含量与翻压量之间存在正相关关系。[结论]不同苕子绿肥翻压模式均可以不同程度的提高烤烟的产量和质量,从内在化学成分的协调性来说,翻压量控制在15000kg/hm2左右较好。

Effects of Different Model of Common Vetch Green Manure Turning Under on Yield and Quality of Flue-cured Tobacco

[Objective]In order to reveal the effects of different turning under model of common vetch green manure turning under on yield qnd quality of flue-cured tobacco.[Method]Taking Yunyan 87 for material,using the method of field test of common vetch green manure and inorganic fertilizer,the effect of different biomass of common vetch green manure turning under on yield and quality of flue-cured tobacco was studied.[Result] The results showed that common vetch green manure turning-over can improve the yield of flue-cured tobacco significantly and increased withed the amount of green manure turning-over.The field of treatment four increased by 2.8% than treatment three and increased by 10.7% than control.In 2007,the field of treatment four improved by 22.74% than control.After flue-cured,the total sugar and reducing sugar in tobacco leaves all increased by the amount of common vetch green manure turning-over.There was a positive correlation between he content of total nitrogen and nicotine and amount of turning-over.[Conclusion]Different turning-over model of common vetch green manure turning-over can improve the yield and quality of flue-cured tobacco,and the amount of turning-over which was controlled in a 15 000 kg per hectare is comparatively well.
