As natural agroecology deteriorates, controlled environment agriculture (CEA) systems become the backup support for coping with future resource consumption and potential food crises. Compared with natural agroecology, most of the environmental parameters of the CEA system rely on manual management. Such a system is dependent and fragile and prone to degradation, which includes harmful bacteria proliferation and productivity decline. Proper water management is significant for constructing a stabilized rhizosphere microenvironment. It has been proved that water is an efficient tool for changing the availability of nutrients, plant physiological processes, and microbial communities within. However, for CEA issues, relevant research is lacking at present. The article reviews the interactive mechanism between water management and rhizosphere microenvironments from the perspectives of physicochemical properties, physiological processes, and microbiology in CEA systems. We presented a synthesis of relevant research on water-root-microbes interplay, which aimed to provide detailed references to the conceptualization, research, diagnosis, and troubleshooting for CEA systems, and attempted to give suggestions for the construction of a high-tech artificial agricultural ecology.
随着自然农业生态恶化,可控环境农业(CEA)系统成为应对未来资源消耗和潜在粮食危机的后备支持。与自然农业生态相比,CEA系统的大多数环境参数依赖人工管理。这样的系统具有依赖性且脆弱,容易退化,包括有害细菌增殖和生产力下降。适当的水分管理对于构建稳定的根际微环境至关重要。事实证明,水是改变养分有效性、植物生理过程以及内部微生物群落的有效工具。然而,对于CEA问题,目前缺乏相关研究。本文从CEA系统的物理化学性质、生理过程和微生物学角度综述了水分管理与根际微环境之间的相互作用机制。我们对水-根-微生物相互作用的相关研究进行了综合阐述,旨在为CEA系统的概念化、研究、诊断和故障排除提供详细参考,并尝试为构建高科技人工农业生态提出建议。
