核桃大树高接换优后能否达到丰产优质目的 ,还需要有相应栽培管理技术来支撑。“九五”期间 ,我们着重研究探索了核桃高接后栽培管理方面的一些问题 ,现将研究结果总结如下。1　高接后 2～ 4年的管理接术1 .1　整形修剪　核桃大树去头高接后 ,当年枝条生长量很大 ,长度大多超过 Walnut tall tree can take advantage of superior high quality yield, but also need to have the appropriate cultivation and management techniques to support. During the Ninth Five-year Plan period, we focused on the exploration and exploration of some problems in the management of high-yielding walnut cultivars. The results of the research are summarized as follows. 1 high then 2 to 4 years of management access 1. 1 plastic trunks tall walnut trees go, then the growth of large branches, most of the length over
