不同比例生物有机肥和复合肥混施对重庆地区烟叶农艺性状和品质的影响

为研究不同比例生物有机肥和复合肥混施对烟草农艺性状及品质的影响，采用田间小区试验，分别设置3种不同施肥处理，分析烟草不同生育期农艺性状、烟叶物理性状、烟叶外观等以及烟叶烟碱、总糖、还原糖等烟草品质指标。结果表明：单施复合肥处理(CK)前期烟草农艺性状优于不同比例生物有机肥和复合肥混施处理(T1和T2)，平顶期T1和T2的农艺性状则较CK组有明显优势；烟草中部叶片物理性状表现为T1处理最优，T2次之，CK最差；烟叶品质方面，T2处理烟叶外观质量有所改善，但其化学成分烟碱含量降低。烟叶品质总体表现为T2最优，

Effect of Combined Application of Bio-organic Fertilizer and Compound Fertilizer on Tobacco Leaf in Chongqing Area

Research the effect on tobacco agronomic traits and quality, which applied different proportions of bio-organic fertilizer and compound fertilizer mixed fertilizer by adopting small plot experiment in the field, are respectively provided with three different fertilization treatments. Analysis at different growth stages of tobacco agronomic traits, physical characteristics of tobacco leaves, tobacco appearance agronomic traits and nicotine, total sugar, reducing sugar, tobacco quality indices. The results show that the single application of compound fertilizer treatment (CK) early tobacco agronomic characters are better than those of the different proportions of bio organic fertilizer and compound fertilizer mixed fertilizer treatment (T1 and T2), flat T1 and T2 agronomic traits is compared with CK group has obvious advantages; T1 treatment is the best physical properties of tobacco leaves of the central, T2 times, CK is the worst; tobacco quality, T2 treatment tobacco appearance quality has improved, but the nicotine content reduce. The overall performance of tobacco leaf quality was T2 optimal, CK times, and T1 treatment was the worst.
