摘 要:为探究水田烤烟施用有机肥的适宜有机质含量及碳氮比,采用自主配方有机肥研究了不同有机质含量及碳氮比对烤烟农艺性状、产量及质量的影响。结果表明:有机肥中有机质含量为50%和65%时,烤烟叶片数、产量和产值总体上高于烟草专用肥处理,且烤后烟叶评吸质量总体上有所提升;有机质含量为35%时,烤烟产量和产值略低于烟草专用肥处理。有机肥中有机质含量提高会促进叶片生长发育和干物质积累,同时上部叶烟碱含量有降低的趋势;有机质含量同一梯度内随着碳氮比的提高,评吸质量提高,且中部叶表现出较高的糖碱比。研究认为,水田烤烟有机肥以有机质含量65%、碳氮比19.54有利于烤烟生长发育及品质提升。The effects of different organic matter levels and C / N ratio on growth,yield and quality of fluecured tobacco were investigated by applying organic manures independently researched. Results showed that leaf number,yield and quality of tobacco increased overall when organic matter levels were 50% and65% compared with CK( applying tobacco special fertilizer),and tobacco smoking quality in general improved after the roast. Yield and quality of flue-cured tobacco at 35% of organic matter were lower than CK. The leaf development and dry matter accumulation speeded up,and the nicotine content of upper leaf decreased with the increase of organic matter content. The smoking quality as well as ratio of sugar and nicotine of middle leaf increased with the increase of C / N ratio at the same level of organic matter.Therefore,the treatment at 65% of organic matter and 19. 54 of C / N ratio advantaged the growth and improved quality of flue-cured tobacco in water field.
