本文报道银杏(Ginhgo biloba Z)小苗(一、二年生)嫁接试验结果。单芽切接、腹切接不仅成活率高且操作简便、工效高,是小苗嫁接值得推广的嫁接方法;嫁接时期应以秋接为主、春接为辅,秋季嫁接时闯长达二个半月,成活率高而稳定、生长期较长;砧木和接穗的年龄对成活率无大影响,建议用多年生(3—5年)接穗嫁接,以利提早结实;一年生双砧嫁接,是快速育苗的重要手段之一。
This article reports the results of grafting experiments on Ginhgo biloba Z seedlings (1st and 2nd year). Single bud cut, abdominal incision not only high survival rate and easy operation, high efficiency, is the seedling grafting deserve to promote the grafting method; Grafting should be autumn-based, supplemented by spring, autumn grafting up to two and a half months , Survival rate is high and stable, longer growth period; rootstock and scion age has no significant impact on the survival rate, it is recommended to use perennial (3-5 years) scion grafting to facilitate early fruiting; One of the important means.
