Research Progress in Light Environment Regulation of Facility Crops

Light intensity in the facility plays a key role in the growth and development of crops and their high-quality production, so the regulation of light environment largely determines the yield and economic benefits of facility crops. In order to make full use of relevant research results at home and abroad, and promote the research and application of light environment regulation technology in China's facility agriculture, this paper summarizes the research progress of light environment regulation technology in facility agriculture from two aspects, namely, light supplement device and light environment regulation method. At the same time, aiming at the current research situation and existing problems in this field of China, this paper proposes some important scientific issues that need to be addressed in the future. This includes establishing a high-precision crop growth model under the influence of multiple environment factors, accurately obtaining the regulation target value of facility light environment, and effective regulation strategies for light environment. The solution of these problems can lay a certain foundation for the theoretical research and construction of intelligent regulation system of facility light environment.
