为实现烤烟废弃鲜叶的最大化利用,研究了以废弃鲜叶发酵产物——沼渣作有机肥对烤烟农艺性状、抗病性、烟叶产质量的影响。结果表明:施用沼渣对烤烟田间主要病害无诱发作用,也不影响烤烟产量,但能明显促进烟叶干物质的积累,提高烤后烟叶经济性状,改善烤后烟叶内在化学成分含量比例,提升感官评吸质量;在一定用量范围内随着沼渣施用量的增加,烤烟田间农艺性状、经济性状、内在化学成分、评吸质量等指标也随之加强;尤其是沼渣施用量为150 kg/667m2的处理,各项指标均表现最优,产值比对照高383.8元/kg。
In order to maximize the utilization of waste fresh leaves of flue-cured tobacco, the effects of biogas residue-biogas residue as organic fertilizer on the agronomic traits, disease resistance and yield and quality of flue-cured tobacco were studied. The results showed that the application of biogas residue had no effect on the main diseases in flue-cured tobacco field and did not affect the yield of flue-cured tobacco, but could significantly promote the accumulation of dry matter in tobacco leaves, increase the economic traits of roasted tobacco leaf, improve the proportion of chemical components in cured tobacco leaves, The quality of smoking and smoking were evaluated. With the increase of biogas residue application rate, the agronomic characters, economic traits, internal chemical composition and smoking quality of flue-cured tobacco increased with the application rate of biogas residue, especially the application rate of biogas residue was 150 kg / 667m2, the indicators showed the best performance, the output value of 383.8 yuan higher than the control / kg.
