摘要
从土壤养分、土壤酶活性、土壤微生物和根系分泌物等的变化探讨了连作障碍的产生机理,综述了国内外对烟草连作障碍的研究进展,并在此基础上提出了一些解决烟草连作障碍问题的措施,展望了后续研究方向。
The cause mechanism of continuous cropping obstacles was discussed from the changes of soli nutrient,soil enzymes activity,soil microorganism and roots exudates. And then the research progress on tobacco continuous cropping obstacles both at home and abroad was summarized,based on which some controlling measures and its future research direction were proposed.
