Abstract:

The optimized number of layers of stereoscopic cultivation was selected by studying the effect of light and temperature of different layers of stereoscopic cultivation on plant growth, yield and quality of fruit. The ‘Hongjia’ was used for comparing type A stereoscopic cultivation model with general plant model on the yield and fruit quality of strawberry during the whole growth period. The result show that the upper layer of the A model has better total solar radiation and temperature condition, the yield and fruit quality are significantly higher than that of general plant model in the early stage (from December to February), and the yield declines sharply in the late stage (from March to May) as the result of early senescence. In general, the yield of the A model with four layers could be increased by 59% in the early stage, and the fruit quality is much better compared with that of the control. This model could achieve more economic benefits than general planting model and has great potential for increasing yield, which is suitable for application and extension in strawberry stereoscopic cultivation.
