This study aims to explore the impact of adopting three-dimensional A word hanging culture system on strawberry production in solar greenhouses. The research focuses on three aspects: the spectral characteristics of planting troughs at different layers, the light absorption and net photosynthetic rates of strawberry leaves, and the yield and quality of the fruits. The three-dimensional A word hanging culture system was used to grow strawberries,and the spectral characteristics, light absorption, and net photosynthetic rates of strawberry leaves at different layers were analyzed at three time points: 9:30, 12:00 and 14:30. The experimental results showed that the light intensity of the upper cultivation tank（U） was higher than that of the other layers at 9:30, 12:00 and 14:30, the light intensity of the eastern middle cultivation tank（EM） and the western middle cultivation tank（WM） was similar at the middle level, and the light intensity of the eastern bottom cultivation tank（EB） and the western bottom cultivation tank（WB） was the lowest. The net photosynthetic rate of strawberry leaves in the U exceeded 12.23 μmol/（m²·s） at all three times, while that of the EM was 11.25 μmol/（m²·s） and 13.01 μmol/（m²·s） at 9:30 and 12:00, but significantly decreased to 3.68 μmol/（m²·s） at 14:30. The WM, in contrast to the EM, was 12.01 μmol/（m²·s） at 14:30, and the net photosynthetic rate of the EB and WB was lower than 8.81 μmol/（m²·s） in both the 9:30 and 14:30. The absorbance of strawberry leaves in the U was the highest in the 450-800 nm band, the EM and WM was slightly lower than the upper layer, and the EB and WB was the lowest, and the absorption valleys and peaks of the absorption of the leaves of the layers were located at the same wavelengths of 554 nm, and 677 nm respectively. The average yield of strawberry fruits in the U was 325.51 g/plant, and the soluble solids content was 12.61% and hardness of1.62 kg/cm², while the yield, soluble solids content and hardness of the middle and lower layers were lower than that of the upper layer. This study provides important scientific evidence for the application of the three-dimensional A word hanging culture system in strawberry production within solar greenhouses.
