摘　　要：嫁接换种是老茶园改造的一种方式,可以快速成园,提早开采,在云南被普遍应用。本文介绍了作者所在嫁接试验小组15年来在云南大叶种茶树嫁接换种技术取得的试验成果。研究表明,嫁接效果与嫁接方式、接穗、砧木和后期管理措施等有关。试验小组创新或改良的四种新式嫁接换种方法均可以把云南大叶种茶树嫁接成活,且效果均较好。云南大叶种群体既适合做云南野生茶树资源的砧木,也可以在福云6号(中叶种)茶树上嫁接换种,其亲和力强,嫁接树长势好。嫁接后适当遮阴可以提高茶树嫁接成活率,其遮光率以75%~85%为宜。四种嫁接换种方式均可以普遍应用推广。Grafting is a pathway to transform old tea gardens,which shows the characteristics of fast growing and early harvest.The achievements of grafting using cultivar‘Yunnan Dayezhong’as rootstocks in the past 15 years were summarized in the present paper.The results showed that grafting effect was related to grafting mode,scion,rootstock and the post grafting management measures.The four new grafting methods obtained by our research team could be efficiently applied to cultivar‘Yunnan Dayezhong’.‘Yunnan Dayezhong’was confirmed to be suitable for rootstock to grafting Yunnan wild tea resources.Cultivar‘Fuyun 6’(a medium-sized leaf cultivar)could also be used as rootstock for grafting wild tea plants.Post grafting shading with 20%-25%light transmittance could improve the survival rate.The four kinds of new grafting methods can be applied to preserve tea resources and rejuvenate the senility tea cultivars.
