| 摘 要： | 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。

| Abstract: | In the present study, it is demonstrated that naturaly open center type isa relatively reasonable shape for peach trees, and leaf area indices are betterranged in 5--6. Peach fruit yield and quality are closely related to light distribution. Fromthe view of yield, fruit are mostly distributed in the layer with relative lightintensities at 30. 9--41. 76% .Degrees of fruit coloration and the ratioes of solu-able solid matter to titrated acid increase as relative light intensities increase. |
