摘要
为探索沼肥在烤烟生产上的应用效果，采用沼渣、沼液在烤烟大田期进行施肥试验。结果表明，施用沼肥对增强烟叶内部物质代谢积累、增加烟叶厚度和油分含量、增强烟叶色泽度、促进烟叶成熟烘烤、提高上中等烟率有明显效果。以沼渣为底肥，沼液作追肥结合沼液叶面喷施5次，分别较常规栽培（对照）上中等烟叶提高24．5％，增产16．22％、增值19．65％，值得应用推广。
The experiment was conducted to investigate the effect of biogas manure on tobacco yield and quality. The results showed that applying biogas manure could improve accumulation of internal metabolic products, leaf thickness, oil content, leaf colour and lustre, and raise the rate of first and second class tobacco significantly. The rate of first and second class tobacco, yield and output value of applying biogas sediment （as base manure） and biogas liquid （as top-dressing and foliage spray）increase by 24. 5 %, 16.22 % and 19.65 % compared with CK respectively.
