1主枝少侧枝多的开心形树冠板栗喜光性强,只有树冠开张,内膛才能形成结果母枝,一般一株树可培养3个主枝,每个主枝有1～2个侧枝,形成自然开心形,对主枝多的树可采用“放”“压”结合的方法,通常采用的做法有:1.1疏枝:疏除多年生大枝如丛生枝、轮生枝、对生枝、重叠枝,大枝的去留根据树冠空间的大小、枝条的分生角度、生长状态等因素综合考虑,疏除强度30%～10%。1.2回缩:根据树冠外围的密集枝条,回缩多在1～3年生部位进行,其余细弱枝全部剪除,集中营养,以每平方米保留8条结果母枝为好。
1 main branch less side branches and more happy-shaped crown chestnut hi light, strong, only the crown opened, the inner bore to form the results of the mother, the general tree can cultivate three main branches, each main branch has 1 to 2 lateral branches to form Natural happy shape, the main branch of the tree can be used “put ” “pressure ” combination of methods commonly used are: 1.1 thinning branches: sparse perennial branches such as tufted branches, Overlapping branches, large branches to leave According to the size of the crown space, branches of the angle of emergence, growth status and other factors considered, sparse intensity of 30% to 10%. 1.2 retraction: According to crowded branches around the crowns, retraction and more in 1 to 3 years to carry out the rest of the fine branches cut off all, concentrated nutrition, to retain 8 results per m 2 as the parent branch is better.
