葡萄绿枝嫁接,方法简便,繁殖系数高。嫁接的植株具有抗寒性强、结果早、坐果率高和浆果早熟等优点。一、嫁接砧木的选择与准备目前,生产上采用的砧木主要有山葡萄、贝达和北醇。各地可根据冬季最低温度来选择适宜的砧木。山葡萄抗寒性最强,但枝条扦插发根能力很弱,宜采用种子播种繁殖砧木。当年春播,第二年夏季嫁接。贝达、北醇的枝条扦插易发根.预先采取催根处理和扣膜覆盖,可于4月上、中旬提前扦插,当年6月即能达到绿枝嫁接的要求。二、接穗的准备根据当地品种区域化的要求,选择优良品种作接穗,采集半木质化的
Grafting grapes green branches, the method is simple, high breeding coefficient. Grafted plants have the advantages of strong cold resistance, early fruiting, high fruit setting rate and early berry ripening. First, the choice of grafting rootstock and preparation At present, the production of the rootstocks are mainly grape, Beida and Bei alcohol. According to the winter minimum temperature to select the appropriate stock. Grape is the strongest cold hardiness, but the ability of cuttings rooting is very weak, should adopt seed sowing breeding stock. Spring that year, the second year of summer grafting. Beida, Bei Ke’s branches are prone to root cutting.Pre-rooted to take root and cover the film, in April, mid-early cuttage, then June that can reach the requirements of green grafting. Second, the preparation of the scion According to the requirements of regional varieties of regional selection of fine varieties for the scion, collecting semi-lignified
