Comparison on Crown Characteristics and Fruit Quality of Different Tree Canopy Shapes
Favorable tree shape has a crucial effect on growing development and fruit quality of fruit tree. With high spindle shape, freedom spindle shape and open center shape as trial trees which are 11-year old, proportion of branch quantity and sort, crown characteristics, photosynthetic characters yield and fruit quality were measured. The results showed that proportions of branch sort of high spindle shape and each target of crown characteristics were better than those of freedom spindle shape and open center shape; the yield of three tree shapes were 56 428. 6, 43 523. 8 and 28 952. 4 kg ? Hm~2 , respectively. The fruit quality of high spindle shape and open center shape was better than that of freedom spindle shape. The quantity of high spindle shape was the best in the three tree shape. The quantity of open center shape was the least in the three tree shape. In conclusion, high spindle shape was better than freedom spindle shape and open center shape.
