核桃是重要的木本油料和营养丰富的干果。为了实现核桃的优种化和品种化,生产更多更好的核桃,满足城乡人民和对外贸易的需要,必须进行选优和采用嫁接繁殖。由于自然条件难以控制,室外嫁接成活率常常低而不稳。山东、辽宁、北京采用室内舌接,成活率可达90%以上。但一般需用二个芽(一个芽被破坏);又由于接穗较长,并接在顶端,移动、搬运很易碰掉。为了摸索新的嫁接方法,提高接穗芽的利用率,
Walnut is an important woody oil and nutrient-rich dried fruit. In order to achieve the superior variety and variety of walnuts, produce more and better walnuts and meet the needs of urban and rural people and foreign trade, we must carry out selection and grafting. Due to the unmanageable natural conditions, the survival rate of outdoor grafting is often low and unstable. Shandong, Liaoning, Beijing indoor tongue, the survival rate of up to 90%. But generally need to use two buds (a bud is destroyed); and because scion is longer, and then connected to the top, moving, handling is easy to get out. In order to explore new methods of grafting, improve the utilization rate of scion buds,
