搞好育苗和加速良种繁育是开拓龙眼良种资源及发展龙眼优质产品的重要工作。已往我们曾采用过切接、芽接、腹接、靠接、高位舌接等几种方法,均各有利弊.1985～1986年我们又改进采用剪顶留叶舌接或切接的快速育苗法,通过12万株嫁接示范证明,办法是成功可行的,可在龙眼产区广泛推广应用。其好处是:操作简便。嫁接成活率达80％以上。时间短,从播种到嫁接仅需一年半左右,育苗到出圃只需二年至二年半时间。比“高位舌接法”可提早一年;经济收益也可提高40～50％;苗势长得好,定植后成活率高;是一项多好省的繁育方法。
Doing a good job of nursery and speeding up the breeding of elite is an important task in developing longan elite resources and developing high quality products of longan. In the past, we have adopted cut, splicing, abdomen, abutment, high Tongue several ways, have their own advantages and disadvantages .1985 ~ 1986 We have also improved the use of shear-leave leaves tongue or cut the rapid seedling method , Through the demonstration of 120,000 grafting demonstration, the method is successful and feasible, it can be widely applied in longan producing areas. The benefits are: easy to operate. Grafting survival rate of 80% or more. Short period of time, only a year and a half from sowing to grafting, nursery to the nursery only two years to two and a half years. Than the “high Tongue Law” can be a year earlier; economic benefits can be increased 40 ~ 50%; seedlings grow well, high survival rate after planting; is a multi-province breeding methods.
