核桃的枝接和室内舌接是当前核桃嫁接所采用的两种主要方法。枝接主要用于大面积品种园和丰产林的营建,即预先统一定植砧木,待其长至一定粗度时再进行枝接;它还用于核桃优良种质资源的汇集和已植劣株树的换冠改造。枝接成活率较高,新疆目前运用较多。 室内舌接是在室内进行的一种嫁接方法,它能有效地控制核桃在露地嫁接时产生的伤流(伤流对嫁接成活十分不利),并能满足愈伤组织)彭成所需的温湿度等条件,具有嫁接成活率高、嫁接苗生长迅速、嫁接时间长、技术简单等优点。
The walnut branches and indoor tongue joints are the two main methods used in current walnut grafting. The branches are mainly used for the construction of large-scale varieties of gardens and high-yield forests, that is, the rootstocks are pre-unifiedly planted until the branches grow to a certain degree of roughness; and it is also used for the collection of excellent germplasm resources of walnuts and the bad plants Tree for crown transformation. Branches followed by a higher survival rate, Xinjiang is currently using more. Indoor tongue is a kind of grafting method indoors, which can effectively control walnut injury in the open grafting (injury stream is very negative for grafting survival), and can meet the callus) Peng into the required temperature Humidity and other conditions, with a high survival rate of grafted, grafted seedlings grow rapidly, grafting for a long time, the advantages of simple technology.
