为筛选适合卷烟工业需求的新型烟叶原料,对晒烤杂种优势新材料Y28进行密度与施肥配套栽培技术试验.结果表明,烟株农艺性状以1300株/666.7 m2+施纯氮5 kg/666.7 m2处理表现较好,烟叶外观质量以1400株/666.7 m2+施纯氮5 kg/666.7 m2处理表现较好,各处理中部烟叶化学成分协调,均表现出高糖、高钾、低碱特征,两糖比、氮/碱和钾/氯适宜,烟叶感官质量以1300株/666.7 m2+施纯氮3 kg/666.7 m2处理和1400株/666.7 m2+施纯氮4 kg/666.7 m2处理表现较好.晒烤杂种优势新材料Y28烟叶品质具有香气质好、香气量较足、杂气轻、香气透发性好、余味的津润回甜、口腔较干净的独特风格特征,符合卷烟工业新型烟叶原料需求.%To screen new tobacco material to meet the demand of cigarette industry,the optimum planting density and fertiliz-ing amount of new tobacco material Y28,a hybrid of sun-cured and flue-cured tobacco,was studied in the present study. The results showed that,for agronomic traits of Y28 seedlings,the best density is 1300 plants combined with 5 kg nitrogen per 666.7 m2. When 1400 plants were planted and 5 kg nitrogen were applied per 666.7 m2,the appearance characteristic and chemical composition of flue-cured tobacco leaves were better than other treatments with high sugar and potassium content, low-nicotine content,appropriate values for reducing sugar to total sugar ratio,nitrogenicotine and potassium/chloride. For flue-cured tobacco leaves sensory quality,two optimum cultivation combinations are 1300 plants with 3 kg nitrogen and 1400 plants with 4 kg nitrogen per 666.7 m2,respectively. Moreover,the heterosis variety of Y28 are with unique characteristics of better smoking aroma quality,enough smoking aroma,less offensive odor, sweet and pure taste, which can meet the increasing demand of cigarette industry for new tobacco raw material.
