果树嫁接就是选取优良品种植株上的枝或芽,接合在与其有良好亲和力的另一植株适当的部位上,使其成为一棵新植株的方法。通过嫁接改换良种植株可提早结果、改善产品质量、增加产量和提高效益。在嫁接过程中,影响果树嫁接成活率的五要素是:1.亲和力的大小。果树嫁接接穗与砧木必须具有良好的亲和力(即接穗和砧木经嫁接能愈合并能正常生长发育的能力)。亲和力是嫁接成活的最基本条件,不论什么果树,哪种嫁接方法,也不管在 Fruit tree grafting is the selection of good varieties of plants on the branches or buds, joined with the good affinity of another plant in the appropriate parts, making it a new plant method. Replacing elite plants with grafts can lead to earlier results, improve product quality, increase yield, and increase profitability. In the grafting process, the five elements that affect the survival rate of fruit tree grafting are: 1. Affinity size. Fruit tree grafting scion and rootstock must have good affinity (ie, scion and rootstocks can be grafted and can grow normally). Affinity is the most basic condition for grafting survival, no matter what fruit trees, grafting methods, no matter in
