油茶嫁接是迅速繁育良种的重要手段之一,对改造现有低产油茶林也起到增产作用。近几年来,各省、区都开展了群众性的油茶嫁接科研活动,应用了嵌合枝接、髓心形成层对接、切接、切腹接、泥接和盾形芽接等多种嫁接方法。但嫁接成活率一般只有40-50%;有些嫁接方法手续繁杂,较难掌握,不易推广。为了尽快突破油茶嫁接技术关,加速油茶良种繁育和现有低产林改造进程,我们于1975年7月下旬组织了以工人为主体的“三结合”攻关小组,进行嫁接试验。针对油茶枝条纤细,木质坚硬,皮层薄,形成层细胞分裂能力弱,愈伤组织形成慢等影响嫁接成活的不利因素,利用其生长期皮层与木质部易于分离的有利因 Camellia grafting is an important means of rapid breeding of improved varieties of existing low-yield Camellia also play an increasing role. In recent years, various provinces and districts have carried out mass grafting on Camellia oleifera, and applied various grafting methods such as chimera sticking, pith forming layer docking, incising, incising, incising, grafting and shield budding. However, the survival rate of grafting is generally only 40-50%; some grafting methods complicated procedures, more difficult to grasp, not easy to promote. In order to break through the technology of Camellia grafting as soon as possible and speed up the breeding of Camellia oleifera seed and the existing transformation of low-yield forests, we organized a “three combination” research team with workers as the main body in late July 1975 to carry out grafting experiments. In view of the slender, hard woody, thin cortical branches of Camellia oleifera, weak cell division ability of cambium and slow callus formation, which are the unfavorable factors affecting the grafting survival,
