腐熟小麦秸秆对烤烟品质的影响

Impact of Decomposed Wheat Straw on the Quality of Flue-cured Tobacco

为探究施用腐熟秸秆对烤烟品质的影响,以中烟100为试验材料,通过田间试验,设置不同腐熟秸杆用量0 kg/hm^2(CK)、3 750 kg/hm^2(T1)、7 500 kg/hm^2(T2)、11 250 kg/hm^2(T3)共4个处理,研究腐熟秸秆施用对烤烟化学成分、致香物质含量、感官质量的影响。结果表明,处理T2、T3的还原糖与总糖比值比CK分别提高5.06%和4.94%,糖碱比处理T3比CK提高了23.39%,钾含量处理T2和T3相对于CK分别提高22.26%和16.12%;处理T2香气物质总量为675.20μg/g,相对于对照提高了32.36%,各处理中性致香物质含量显著高于对照;香气质、香气量、浓度、杂气和燃烧性得分均以处理T2最高,处理T2的感官质量总得分也最高,为62.71,其次为处理T3,总得分为62.43。综合来看,施用腐熟秸杆可以提高烤烟品质,施用量为7 500 kg/hm^2最佳,结果为河南浓香型特色烟叶生产提供参考依据。

In order to explore the effect of decomposed straw on the quality of flue-cured tobacco,this paper took'Zhongyan 100'as test material,set up 4 treatments of different decomposed straw dosages,including 0 kg/hm^2( CK),3 750 kg/hm^2( T1),7 500 kg/hm^2( T2),11 250 kg/hm^2( T3);and studied the effects of decomposed straw on chemical composition,aroma content and sensory quality of flue-cured tobacco by field trials. The results showed that the ratios of reducing sugar and total sugar of T2 and T3 were 5.06% and 4.94% higher than that of the CK,respectively;sugar-nicotine ratio of T3 was 23.39% higher than that of the CK;potassium contents of T2 and T3 were22.26% and 16. 12% higher than that of the CK. The total amount of aromatic substance in T2 was 675. 20 μg/g increased by 32. 36% than that of the CK,and the contents of neutral aromatic substance in all treatments were significantly higher than that of the CK. The aroma quality, aroma quantity, concentration, stray air and combustibility of T2 were the highest,and total sensory quality score of T2 was the highest at 62.71,followed by T3 at 62.43. On the whole,the application of decomposed straw could improve the quality of flue-cured tobacco. The best application quantity was 7 500 kg/hm^2. Those results provided reference basis for producing flue-cured tobacco with strong-flavor of special type in Henan province.
