芽接是经济利用接穗,成活率高,嫁接时期长的一种嫁接方法。生产上繁殖苗木、改劣换优,常采用此法。影响芽接的成活因素很多,关键是: 一、掌握好嫁接时期。适宜芽接的时间较长,春、夏、秋三季砧木“给皮”时均可进行。但成活率最高的是秋季(除核桃、枣树),即七月下旬至九月初。因这时的形成 Budding is the economic use of scion, high survival rate, a long period of grafting method of grafting. Production breeding seedlings, change the merits, often use this method. Many factors affect the budding survival, the key is: First, grasp the grafting period. Suitable for budding a longer time, spring, summer and autumn rootstock “to the skin” can be carried out. But the highest survival rate is the fall (except walnut, jujube), that is, from late July to early September. Because of the formation of this time
