桃的树冠以自然开心形树形较为合理,叶面积系数以5～6为宜。光分布与果实产量、品质有较为密切的关系。从产量看果实主要分布在相对光强为30.19～41.76%的层间内。果实着色的程度、可溶性固形物与滴定酸的比值随相对光强的增加而增加。
Peach tree with a natural shape of tree-shaped more reasonable, leaf area factor of 5 to 6 is appropriate. Light distribution and fruit yield, quality are more closely related. From the yield to see the fruits are mainly distributed in the relative light intensity of 30.19 ~ 41.76% of the floor. The degree of fruit coloring, soluble solids and titration acid ratio increased with the relative light intensity.
