| 摘 要： | 以烤烟品种吉烟9号为材料,探讨了连作对烤烟根际微生物和内在品质的影响。研究表明,连作烤烟根际的细菌、真菌数在烟株生长后期显著增加;土壤pH减小,有机质、碱解氮、速效磷含量在移栽后20 d至40 d较高,总体来说,连作1年化学成分均衡、致香物质总量较多,更接近优质烟指标。

| Abstract: | Tobacco cultivar Jiyan 9 was used to investigate the effects of continuous cropping on the rhizosphere microorganisms and internal quality of flue-cured tobacco in Yanbian area.The results showed that: in continuous cropping,the number of rhizosphere bacteria and fungi increased significantly in the later period of tobacco plants growth;the soil pH-value decreased,and the organic matter,available nitrogen and available phosphorus contents in the soil were higher from the 20th day to the 40th day after transplanting.As a whole,the tobacco which was continuously cropped in the first year had more balanced chemical compositions and more amount of fragrance matter. |
