Abstract:
With ‘Beijing Red’ and ‘Kubo’ peach fruit as materials，the changes in canopy parameters and the effect of yield and quality by peach tree shape (‘Y’ shape and natural open shape) were studied.The results showed that in high-yield and high-quality orchards，leaf area index increased with the increase of new branch growth，and reached the maximum value from late May to early June，then changed gently.While the change trend of canopy light transmittance，total direct radiation，total scattering and total radiation under the canopy，which reached the minimum value from late May to early June，was opposite to that of leaf area index.And the change trend could stay at a suitable range after summer pruning.There was no obvious difference between the two kinds of peach tree shape in leaf area index，canopy light transmittance，radiation under the canopy，and the index of fruit quality and yield.
