以Y字形修剪桃树为试材,根据山东泰安地区的太阳照射角,计算了不同树高、干高和夹角的行距和2个主枝的遮挡情况,并研究了适合Y形树形的2个主枝夹角及行距。结果表明:同一树高,行距随干高的升高而减小,随2个主枝夹角的增大而增大;行距随树高的增大而增大。通过计算得出的2个主枝夹角最小角度应为72.04°,为方便生产,可将2个主枝的夹角定为75°,合适的种植行距为4.45m(树高3.5m,干高0.6m)或者5.22m(树高4.0m,干高0.6m)。
According to the solar irradiation angle of Tai’an in Shandong Province, the row spacing of two tree branches with different tree heights, dry heights and included angles and the occlusion situation of two main branches were studied with Y-shaped pruning peach trees as test materials. 2 main branches angle and spacing. The results showed that the same tree height and row spacing decreased with the increase of stem height, and increased with the increase of the angle between two main branches. The row spacing increased with the increase of tree height. The minimum angle between two main branches calculated by calculation should be 72.04 °. For the convenience of production, the angle between the two main branches can be set as 75 °. The suitable planting distance is 4.45 m (tree height 3.5 m, dry 0.6m high) or 5.22m (tree height 4.0m, dry height 0.6m).
