不同树形对85-007桃树冠、产量和品质的影响

研究了4种整形树形对85-007桃树树冠大小、树高、单株产量、单果重、果实品质等指标的影响．结果显示：85-007桃树采用拉大主枝角度开心形整形，树形矮化、冠幅大，平均单株产量、可溶性固形物和维生素C含量较其余三种树形的高，果实含酸量相对其它树形的低．开心形整形树形较矮化、冠幅较大，株产和果实维生素含量较高．二主枝开心形整形株型也较矮化，平均单果重最重，可溶性固形物含量较高．纺锤形整形树形高，果较小，平均株产低，果实品质较差．这些分析表明85-007桃树采用拉大主枝角度开心形整形是一种较好整形修剪模式．

Effects of Different Training and Pruning on Canopy,Yield and Quality in Peach Variety 85-007

In this study,we analysed effects of four different training and pruning on size of canopy,plant high,yield per plant,weight per fruit and fruit quality in peach 85-007.The results showed that the tree-type,crown-width,production and fruit quality were improved by using open-centre training system with large angle bough,which was compared with the other three training systems.The tree-height was the relative decrease and the size of canopy,yield per plant and Vc content of fruit were the relative increase by using nature open centre training system compared with Y form and spindle form training systems.Peach tree with Y form training had the biggest the weight per fruit,while there was relative dwarf plant and the content of soluble solid materials was more than that of the nature open centre and spindle form training systems.Spindle training system had an negative effects on the tree-type,production and fruit quality comparing with the other three training systems.All analysis above indicated that open-centre training system with large angle bough was a better training mode in 85-007 peach.
