高接换优技术是对低产劣质油橄榄进行改造提高产量和品质的有效途径之一。采用插皮接法,成活率达98?以上。低产树和实生树经过高接换优2~3 a恢复树冠,第3年开始试花试果,第4年株产可达4~8 kg。本文着重论述了砧木选择、良种接穗的采集和贮藏、嫁接方法时间和高接后的放风、除萌、松绑、绑支柱及整形修剪、间种绿肥等一系列管理措施。
High takeover technology is one of the effective ways to transform low-yield and low-quality olive to improve yield and quality. Intercalation method, the survival rate of 98? Low-yielding trees and the real tree after high takeover excellent 2 ~ 3 a crown recovery, the first three years to test the flowers, the first 4 strains of up to 4 ~ 8 kg. This article focuses on the selection of rootstocks, the collection and storage of elite scion, a series of management measures such as grafting, grafting, loose binding, tied strut and plastic pruning, intercropping green manure and so on.
