不同用量烟草专用肥对烤烟生长及品质的影响

Effects of Different Amounts of Specialty Fertilizer for Tobacco on Growth and Quality of Flue-Cured Tobacco

采用随机区组试验,研究了"太阳岛"牌烟草专用肥不同施用量对烤烟生长及品质的影响。结果表明:施用烟草专用肥能够促进烟株生长发育,高施用量处理烤烟的农艺性状表现较好,其烤后烟叶产量和产值最高。但综合烟叶外观质量、化学成分和感官质量分析,"太阳岛"牌烟草专用肥666.7m2施用量以纯氮7kg较为适宜,能够获得较好的烟叶品质和种植效益。

Random block experiment was designed to study the effects of different application amounts of＂Taiyangdao＂specialty fertilizer for tobacco on growth and quality of flue-cured tobacco. The results showed that specialty fertilizer for tobacco could promote growth and development of tobacco plants. The flue-cured tobacco had better agronomic characters and the highest yield and output value under high fertilizer application amount treatment. Comprehensive analysis of appearance quality,chemical component and smoking quality indicated the optimum application amount of＂Taiyangdao＂specialty fertilizer for tobacco was 7 kg pure nitrogen per 666. 7m2,which could obtain better tobacco quality and planting benefit.
