有机无机肥配比对生态烟叶产质量的影响

Effects of Different Proportions of Organic and Inorganic Fertilizers on Yield and Quality of Ecological Tobacco

通过田间对比试验,研究了不同有机无机肥对烤烟产质量的影响。结果表明,有机氮比例为25%~50%,能促进烟株早发;有机氮比例为12.5%,烟叶产值和上等烟比例最高;随着有机氮比例提高,收益呈递减趋势,上部叶的感官评吸质量明显改善。总体上,有机氮为25%最有利于烤烟产质量的提高。

Effects of different proportions of organic and inorganic fertilizers on yield and quality of flue-cured tobacco were tested through the field comparative experiment. The results showed that the ratio of organic nitrogen at 25%-50% could promote the early growth of tobacco plant; output value and the proportion of superior leaves were the highest with the ratio of organic nitrogen at 12.5%; the yield income showed a decreasing trend, and the sensory quality of the upper leaves improved significantly with the proportion of organic nitrogen increasing. On the whole, the organic nitrogen at 25% was most conducive to improving the yield and quality of flue cured tobacco.
