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.
