摘要
为了解决南江3号品种特性对烟叶品质的不利影响,提高南江3号烟叶质量,在原施肥方案基础上进行了增施不同用量饼肥试验。结果表明,施用饼肥对烟株的生长发育性状影响不明显,但可显著提高烟叶质量,烟叶上中等烟比例增加9%,均价提高了1.6元/kg。饼肥施用量8 kg/667m2的烟叶外观质量较好,总糖和还原糖含量降低,烟碱和总氮比例更趋于1∶1,烟叶内在化学成分更加协调,烟叶评吸结果较对照好,施用饼肥对改善烟草内在质量具有明显的效果。
Nanjiang 3,a flue-cured tobacco variety,was applied with different amounts of rapeseed cake fertilizer based on the original fertilizing method to improve its leaf quality.The results showed that applying rapeseed cake fertilizer had no obvious effect on growth and development of tobacco plants and improved its leaf quality significantly,the proportion of tobacco leaves with first and medium rank increased by 9% and the average price of tobacco leaves increased by 1.60 Yuan/kg.The indexes of external quality,total sugar and reducing sugar content,ratio of nicotine to total nitrogen,chemical composition coordination and smoking evaluation of tobacco leaves applied with 8kg/667m2 rapeseed cake fertilizer were the best in tested treatments.There were significant effect on inherent quality of flue-cured tobacco when applied with rapeseed cake.
