- 摘要:
- 通过减施化肥增施不同种类和数量有机肥对烤烟根系和产质量的影响的研究,结果表明:(1)减施化肥增施有机肥提高了烟株根系活力,以有机肥施用量较多的处理表现较好,相同有机肥施用量比较又以施用生物有机肥的处理较好些。(2)减施化肥增施有机肥降低了根系鲜干重和田间病害发病率,但随着有机肥施用量的增加,根系鲜干重有逐渐增加的趋势,田间病害发病率有降低的趋势。(3)上等烟比例、均价和产值均以施常规化肥750 kg·hm-2+精致有机肥225 kg·hm-2处理较高。减施化肥增施有机肥处理相比,随着减施化肥和增施有机肥数量的增加,上等烟比例和均价逐渐增加,但产量和产值下降。(4)减施化肥增施有机肥提高了钾含量,降低了烟碱、总糖、还原糖、淀粉和氯含量,但各处理相差不大。(5)减施化肥增施有机肥各处理烤后烟叶评吸质量差异较小,基本属同一档次,对感官评吸的影响主要在杂气和刺激性方面有所差异。
- Abstract:
- The effects of reducing amount of chemical-fertilizers and increasing different kinds of and amount of organic manures were studied on the root,yield,and quality of flue-cured tobacco.The results showed that:⑴The root activity was improved.Among the treatments,the effect of the more organic fertilizer application rate was better,and the effect of applying bio-organic fertilizer was better with the same application organic manures.⑵The root weight and the incidence of field disease were reduced,and the root weight was gradually increased and the incidence of field disease was reduced with the increase of organic fertilizer.⑶The proportion of superior tobacco leaves and the average price were increased,but the leaves yield and value were declined.The proportion of superior tobacco leaves,the average price and value were the best when applying 750 kg·hm-2 chemical-fertilizers and 225 kg·hm-2fine organic manures.⑷The leaf potassium content was increased and the nicotine,total sugar,reducing sugar,starch,chlorine content were decreased,but there were not significant difference among the treatments.⑸The total smoking quality of cured tobacco leaves had little difference,but the mixed and the irritant gas had some differences.
