在有些地区,推广的板栗高接换种嫁接技术为插皮枝接。这种嫁接方法的优点是砧穗接合部愈合快、包合完整,接穗留两个芽以上,成冠快。但是存在着接穗用量大,嫁接时间短,嫁接速度慢,捆绑费工等缺点。笔者从1994年开始使用单芽腹接法在闽西地区的新罗、上杭、长汀、连城及宁化等地高接2～10年生的实生板栗树6万多株,200多hm~2,每株接3～12个芽。 采用此法高接换种有如下优点:接穗贮藏方法简单,只需用地膜捆扎包装,不需封蜡;接穗用量少,一个接口只需一个芽;嫁接速度快,接穗的削取一气呵成,绑扎时只需用薄膜带封紧接穗即可;扶绑容易、省工,扶绑时可将接口上10cm左右的残桩作支柱,不必重新立支架;成活率高,嫁接部位在截口处
In some areas, the promotion of chestnut high exchange grafting technology for cuttings. The advantage of this grafting method is that the anvil spike junction heal fast, complete inclusion, leaving more than two buds spike, into the crown faster. However, there is a large amount of scion, grafting time is short, slow grafting, bundling and other shortcomings. From 1994, the author started to use the single bud method in more than 60,000 strains of chestnut trees with annual output of 2 to 10 years in Shilao, Shanghang, Changting, Liancheng and Ninghua in western Fujian, 2, each plant then 3 to 12 buds. The use of this method of high takeover has the following advantages: Scion storage method is simple, just wrapped in plastic wrap, without sealing wax; scion with less, an interface only a bud; grafting speed, scion cut in one go, When banding, it is only necessary to seal the scion with a film tape. It is easy to bind and labor-saving. When the banding is carried out, the stump of about 10cm can be used as the pillar without the need to re-bracket the stent. The survival rate is high,
