植物连作障碍及其调控技术在烤烟栽培中的应用

Research on Plants Continuous Cropping Obstacle and Its Application in Flue-cured Tobacco Cultivation

针对农业生产中普遍存在的连作障碍现象,综述了连作对作物的影响,从土壤理化性质恶化、土壤微生物变化、化感作用与自毒作用3个方面论述了植物连作障碍的作用机理,从多种作物上证实植物连作障碍的存在。在此基础上,探讨了植物连作障碍调控技术在烤烟栽培中的应用。

Obstacle of continuous cropping is an ordinary phenomenon in agriculture production. The effect of continuous cropping on crops was reviewed. The formation mechanism of plants continuous cropping obstacle was reviewed from aspects of soil physical and chemical properties deterioration,soil microbial change,allelopathy and allelopathic autotoxicity. And the existence of continuous cropping obstacle was confirmed on many crops. The application of continuous cropping obstacles in flue-cured tobacco cultivation was also discussed in this paper.
