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。
In order to explore the suitable organic matter content and C / N ratio of organic fertilizer for flue-cured tobacco, the effect of different organic matter content and C / N ratio on the agronomic characters, yield and quality of flue-cured tobacco was studied with self-formulated organic fertilizer. The results showed that when the content of organic matter in organic fertilizer was 50% and 65%, the number of leaves, the yield and the output value of flue-cured tobacco were generally higher than those of tobacco special fertilizer, and the smoking quality of cured tobacco generally increased. The content of organic matter was 35% , The output and output of flue-cured tobacco is slightly lower than that of tobacco special fertilizer. The increase of organic matter in organic manure could promote leaf growth and dry matter accumulation, while the content of nicotine in the upper leaf tended to decrease. With the increase of C / N ratio in the same gradient of organic matter content, the quality of smoking increase, and the middle leaf showed Higher ratio of sugar to alkali. The study suggests that the organic fertilizers of paddy flue-cured tobacco have the organic matter content of 65% and the C / N ratio of 19.54 in favor of the growth and quality improvement of flue-cured tobacco.
