In order to efficiently solve the shading problem between the upper layer and lower layer in the same cultivation system and between adjacent cultivation systems in multi-layer stereo-cultivation of strawberry,and to improve the fixed A-frame system,a novel cultivation system-sun-tracking system was developed that could keep north-south line of cultivation frame parallel to sunray to make the best use of direct light.In this study,crop canopy light condition of sun-tracking and fixed systems were tested and compared.Results showed that integrated PPF of sun-tracking system is higher than that of fixed system in both middle and lower layers.On sunny day compared with fixed system,integrated PPF on middle and lower layer of suntracking system increased by 16.0％,9.1％ in January and 19.6％,4.1％ in February,while on cloudy day improvement on light condition of sun-tracking system is not evident as sunny days.Thus sun-tracking system can effectively alleviate shading problem between layers and improve plant canopy light environment.
