3术语和定义

3.1

高接换种topworking

在原有品种的枝干上通过高位嫁接改接优良品种，进行品种更新。

4果园选择

树龄20年以下，树势较健壮，无严重病虫危害，但品种不适宜当地环境、不适应市场需求的果园。

5品种选择

选择国家柑橘优势布局适宜、与中间砧亲和性好的优良品种，品种选择见附录A。所选品种纯正，

接穗健壮、芽眼饱满、无检疫性病虫害，接穗检疫按GB5040的规定执行。

6高接

6.1时间

主要选择萌芽前3月上旬至4月上旬，其次是6月初至10月底。

6.2部位与芽数

1

DB43/T2598—2023

树龄10年生以下的树嫁接口距离地面80cm以下的主枝、副主枝或主干，每株嫁接6个～10个芽；

树龄10年生以上20年以下的树，嫁接口距离地面宜在100cm以下的副主枝、主枝和侧枝，每株嫁接

10个～15个芽。

6.3方法

6.3.1春季切接

6.3.1.1选留嫁接枝与辅养枝

选留3-4个不同方向、分布均匀、直立的健壮主枝或副主枝作为高接枝，80cm～100cm处切枝。

选留1～2个低于高接部位以下枝作辅养枝，下部无枝则选留1个开张角度大的主枝或副主枝作辅养枝，

辅养枝枝梢保留原树冠的1/4～1/5，余下枝从基部去除。

6.3.1.2其它嫁接技术要点

参照N/T971的要求执行。

6.3.2秋季腹接

参照N/T971的要求执行。

7高接后管理

7.1第一年

7.1.1高接后日常管理

补接、解膜、摘心、立枝柱与除萌等，按GB5040的要求执行。

7.1.2剪辅养枝

高接后分二次剪砧去辅养枝。春接后第一次剪砧于6月上中旬春梢老熟后剪除旺长、遮光的1/2

辅养枝梢，或弯曲折断一半辅养枝干，使整个辅养枝梢低于嫁接枝梢；第二次于9月上旬剪去全部辅养

枝。秋季腹接剪
