Abstract:

In order to explore the effects of cylindrical tree shape and trellis tree shape on the canopy structure and fruit quality of pear, and to provide reference for selecting suitable tree shapes in southern pear orchard, this study used Cuiyu and Cuiguan pear as experimental materials, and measured the labor cost, growth and development, disease incidence and fruit quality of two tree shapes. The results showed that the total number of branches of cylindrical tree type was significantly (P<0.05) higher than that of trellis tree type. The disease resistance of cylindrical tree type was improved. Total soluble solids(TSS) contents of Cuiguan pear in different directions of cylindrical tree shape and trellis tree shape were between 12.00% and 13.00%, and single fruit weight were between 300.00 g and 400.00 g, both of which were higher in trellis tree shape than in cylindrical tree shape. The labor amount of cylindrical tree shape was less than that of trellis tree shape, and the cylindrical tree shape was also conducive to mechanization. In the actual production, it is recommended to use cylindrical tree shape for large-scale commercial production, while it is recommended to use trellis tree shape for sightseeing picking.
