有机肥对烤烟产量及品质的影响

在同一施无机肥水平条件下。研究了增施腐熟有机肥对烤烟生长发育和烟叶产量、品质的影响。试验结果表明：移栽后35d、50d、65d施用有机肥各处理的株高、单株叶面积均明显大于对照，干物质积累比对照多．烟株生长较快。施用有机肥的处理产量比对照增加2．14％-8．45％，产值增加11．99％～25．22％，上等烟比例增加2．06％～10．43％。施用有机肥的处理上部烟叶的总糖、还原糖含量均低于对照．总氮、烟碱、蛋白质含量均高于对照；中部烟叶的总糖、还原糖含量均高于对照：下部烟叶的烟碱、钾含量均高于对照。施用有机肥的处理的香气量、余味、杂气、刺激性及评吸得分均高于对照，表明施用有机肥可改善烟叶的品质。红花大金元烤烟品种的腐熟有机肥最佳施用量为2400g／株。

Effect of Organic Fertilizer on Yield and Quality of Flue-cured Tobacco

In the same inorganic fertilizer level condition,effects of applying fully-fermented organic manure on flue-cured tobacco development and leaf yield and quality was studied.The results indicated that compared with control,the height,individual plant leaf area and canopy biomass accumulation of each treat,including applying organic manure at 35d,50d,65d after transplant,was higher,and the plant grew faster.The application of organic manure increased 2.14% ~8.45% in yield,11.99%~25.22 % in output value and 2.06%~10.43% in proportion of superior leaf.The application of organic manure reduced the total sugar and reducing sugar content,however,increased total nitrogen,nicotine and protein content of upper leaf.It enhanced the total sugar and reducing sugar content of middle leaf and enhanced the nicotine and potassium content of bottom leaf.The aroma volume,offensive taste,offensive odor and lingering odor and total smoking quality scores of organic manure application treat was higher than that of control.These showed that the application of organic manure can improve the leaf quality.The optimal application amount of each plant was 2400g fully-fermented organic manure on Honghuadajinyuan breed.
