Current status and challenges of research in facility environmental control technology
[Purpose]The purpose of this paper is to introduce the current status of research and application of environmental monitoring and regulation model strategy technology in facility agriculture,to analyze the challenges facing by China in the field of intelligent regulation of facility environment and to put forward corresponding countermeasure suggestions.[Method]First,the research progress and application status of facility environment monitoring,regulation methods and technologies at home and abroad were systematically introduced.Second,the current problems and challenges of environment regulation in facility production were analyzed.Finally,relevant countermeasure suggestions were put forward to cope with these challenges.[Result]Facility agriculture in China developed rapidly,and the application of environmental regulation technologies and strategies had made remarkable progress,achieved the goals of reducing artificial dependence and improving production efficiency.However,there were still real challenges such as single regulation target,lack of cost consideration and insufficient level of intelligence.[Conclusion]In order to further promote the application of environmentally intelligent control technology in facility agriculture production,and to achieve high efficiency and standardisation of facility agriculture production,this paper puts forward the following suggestions.First,further promote the technological innovation of environmental control model strategy,focusing on multi-environmental factor coupling control objectives,while achieving a balance between crop growth and control costs.Second,we should increase the investment in infrastructure of facility agriculture,and build independent,controllable,stable and perfect environmental control system and equipment.Third,we should strengthen the synergy of government,industry,academia,research and application,and open up the"last kilometre"for the transformation of scientific research results.
