我国设施栽培土壤退化特征及修复技术研究进展

Research Progress on Degradation Characteristics and Remediation Techonologes of Protected Soils in China

为了解决由设施种植面积扩大和栽培年限增加而导致设施土壤质量退化日趋严重的问题,系统阐述了设施栽培土壤次生盐渍化、酸化、连作障碍和重金属累积等方面的退化特征及成因,并基于退化特征综述了相对应的改良与修复(包括农艺措施和工程修复措施)技术研究进展,分析了设施栽培土壤退化修复研究中改良剂产品、轮作制度、栽培模式等方面的不足,提出了完善土壤改良调理剂产品标准、实行合理种植模式、定时对设施大棚进行健康评价、拓展新型设施栽培模式等应对策略。

In order to solve the increasingly serious problem of quality degradation of facility soil caused by the expansion of facility planting area and the increase of cultivation years,the degradation characteristics and causes of secondary salinization,acidification,continuous cropping obstacles and heavy metal accumulation of facility cultivated soil were systematically expounded,and the corresponding technological research progress of improvement and restoration were summarized based on the degradation characteristics(including agronomic measures and engineering restoration measures).The deficiencies of improver products,rotation system and cultivation mode in the research of soil degradation remediation of protected cultivation were analyzed,and some countermeasures were put forward,such as improving the standard of soil improver products,implementing reasonable planting mode,regularly evaluating the health of protected greenhouse,expanding new protected cultivation mode and so on.
