琯溪蜜柚大树高接三红蜜柚技术试验

摘要

In order to explore the technique of top grafting with three red honey pomelo on Guanxi honey pomelo tree, the experiment with different grafting methods , different grafting time and the auxiliary branch was carried out .The results showed that the double-layer grafting with 3～5 auxiliary branches in autumn grafting in mountain or winter grafting in plain made for water transpiration to prevent the root -stock split and rot , that the survival rate was more than 96％and the crown formed quickly and went into production in the third year by timely cutting off the auxiliary branches and managing new branches after grafting, which had good economic benefits .%为探索琯溪蜜柚大树高接三红蜜柚技术,开展了不同嫁接时间、不同嫁接方法及是否留辅助枝嫁接试验.结果表明,采用双层嫁接方法,在山区果园冬接、平原地区果园秋接,留辅助枝3～5枝有利于水分蒸腾,以防止砧木皮裂与烂根;适时剪除辅助枝,并及时做好嫁接后新梢管理工作,可使嫁接成活率达96％以上,树冠形成快,接后第3年投产,具有较好经济效益.
