1枣树丰产树形的结构及整形修剪枣树的树形有主干疏层形、自然开心形、多主枝自然圆头形等。1.1主干疏层形具有明显的中央领导枝,全树有主枝7个,分三层。层间距1.2m左右(第二层至第三层的间距略小),主枝开张角度为50～60度,每主枝上选留侧枝1～3个,侧枝间距70cm左右,树高控制在5～6m。本树形特点是层性明显,主侧枝配置合理,冠内通风透光,树体健壮,寿命长,是较好的树形。

A jujube tree structure and plasticity pruning Jujube tree trunk sparsely layered, natural happy shape, the main branch of the natural round head and so on. 1.1 trunk sparse layer has obvious central leading branches, the main tree has seven branches, divided into three layers. Layer spacing of about 1.2m (the second layer to the third layer spacing slightly smaller), the main branch opening angle of 50 to 60 degrees, each on the main branch to choose to stay 1 to 3, the lateral branch spacing of about 70cm, tree height control 5 ~ 6m. The tree is characterized by stratum obvious, the main collateral configuration is reasonable, the crown of the air and light, robust tree, long life, is a good tree.
