摘要
连作是目前我国设施农业的主要栽培方式,连作障碍是土壤修复的世界性难题。本文系统阐述了国内设施栽培出现的连作障碍特征(如酸化、盐渍化、养分失衡、重金属及其他有害物质积累、土传病害发生严重)与成因,并分别从农艺、生物、化学、物理4个方面简述了各种防治技术在缓解设施连作障碍过程中的作用效果。最后总结了设施连作障碍及防治技术研究中尚待解决的科学问题及研究方向,以为我国设施连作障碍的发生发展机理研究和防治技术提供科学依据。
Continuous cropping is currently the main cultivation method for facility agriculture,and continuous cropping obstacles are a worldwide problem in soil remediation.The characteristics of continuous cropping obstacles(such as acidification,secondary salinization,nutrient imbalance,accumulation of heavy metals and other harmful substances,serious soil-borne diseases)were systematically expounded in facility cultivation in China.The roles and effects of various regulation techniques in mitigating continuous cropping obstacles were briefly described from agronomical,biological,chemical and physical aspects.Based on these studies,the existing scientific problems and future research direction in continuous cropping obstacles and regulation technology in facilities cultivation were summarized in order to provide scientific basis for studying the regulation mechanism and technology of the continuous cropping obstacles in China.
