摘要 为了完善油茶大树嫁接接口处理技术,提高嫁接成活率,在湖南省长沙市望城区试验基地,采用随机区组试验方法,以树龄为25 a的油茶树为砧木,以湘林XLC15为接穗,就不同包扎方式、封盖处理、药剂处理和激素处理等接口处理技术对油茶嫁接成活及新梢生长等方面的影响情况进行了油茶大树插皮枝接试验。结果表明:采用锡箔纸包扎的嫁接成活率最高,其新梢生长量较大,嫁接后第3年无枯桩现象;采用封蜡处理的嫁接成活率最高,新梢生长量最大,嫁接后第3年无枯桩现象;采用杀菌剂处理的嫁接成活率最高,其新梢生长量最大,嫁接后第3年其枯桩数略低于防腐剂处理的;采用IAA处理的嫁接成活率最高,其新梢生长量最大,嫁接后第3年无枯桩现象。 In order to improve technique of interface treatment during bark grafting of bigCamellia oleifera trees, and to improve survival rate of grafting, a randomized block experiment of bark grafting of big C. oleiferatrees was put forward at a test base of Wangcheng, Changsha. 25-year-oldC. oleiferatrees was used as rootstocks, and XLC15 was as scions. The effects of binding methods, covering methods, drugs and hormones on survival situation and new shoot growth were researched. The results showed that the survival rate of foil paper procession in the binding methods was the highest, the increment of new shoot was the higher, and there was no dry pile phenomenon after 3 years. The survival rate of wax covering procession in the covering methods was the highest, the increment of new shoot was the highest, and there was no dry pile phenomenon after 3 years, the survival rate of bactericide procession in the drugs was the highest, the increment of new shoot was the highest, and the dry pile number was lower after 3 years. The survival rate of IAA procession in the hormones was the highest, the increment of new shoot was the highest, and there was no dry pile phenomenon after 3 years.
