发酵饼肥与减少采收次数对烤烟产质量的影响

研究了施用发酵饼肥与减少采收次数对烤烟产质量的影响,结果表明在相同的施氮量情况下,增施发酵饼肥和减少采收次数均不对烤烟产量产生显著影响,但施用发酵饼肥能提高烟叶糖含量和钾离子含量,而适当减少采收次数能有效降低中、上部烟叶的烟碱含量,二者均能提高烟叶香气质、香气量和吃味,改善烟叶品质,提高上中等烟比例和产值。以施用发酵饼肥225 kg/hm2+10 d采收1次效果最好,产值和上等烟比例分别达到35078.10元/hm2和67.42%。

Effect of Applying Fermented Oil-cake Fertilizer and Reducing Harvest Times on Yield and Quality of Flue-cured Tobacco

The effect of using fermented oil-cake fertilizer and reducing harvest times on the yield and quality of flue-cured tobacco was studied.The results showed that both applying the fermented oil-cake fertilizer and reducing the harvest times had no remarkable effect on the yield of flue-cured tobacco under the condition of the same nitrogen application rate,but the contents of sugar and potassium ion（K＋） in tobacco leaves were improved by using more fermented oil-cake fertilizer,and the content of nicotine in the upper and middle leaves could be effectively decreased by reducing the harvest times appropriately.Both the above two methods could improve the fragrance quality,fragrance quantity and taste of tobacco leaves,improve the quality of tobacco leaves,and enhance the ratio of upper-class and middle-class tobacco and production value.The combination of applying fermented oil-cake fertilizer 225 kg/hm^2 and harvesting once every 10 days had the best effect,and the production value and the ratio of the upper-class tobacco could be up to RMB 35078.10 yuan per hectare and 67.42% respectively.
