不同树形青脆李光合特效及果实品质的研究

以4 年生青脆李为试材，在相同光照条件下，比较了三主枝开心形、四主枝开心形、主干形、Y字型、UFO形五种树形青脆李的光合作用强度及果实品质，综合比较光合作用强度及果实品质均表现为四主枝开心形最佳，其次是Y字形和三主枝开心形，最后是UFO形和主干形。

Study on photosynthetic effect and fruit quality of green crisp plum with different tree shapes

Taking 4-year-old green crisp plum as the test material,and under the same light condition, the photosynthetic intensity and fruit quality of five tree shaped green crisp plum, namely, three main branch open center, four main branch open center, trunk shape, Y-shape and UFO shape, are compared. By comprehensive comparison, the photosynthesis intensity and fruit quality of the four main branch open center are the best, followed by Y-shape and three main branch open center, and finally UFO shape and trunk shape.
