我省辽西和辽南地区酸枣资源丰富,利用酸枣做砧木嫁接大枣,不仅生长快、结果早,而且投资少、见效快。因此,有“酸枣接大枣,满山都是宝,不用栽不用造,接上当年就挂枣”的说法。枣树的嫁接方法很多,采用单芽插皮嫁接,不仅嫁接时期长、成活率高,而且操作简便、节省用工。1.嫁接时期:5月至9月,即酸枣树离度开始到护皮为止均可嫁接,嫁接时期150天左右。2 砧木处理;选用5年生以下,直径在1厘米以上的幼龄酸枣树做砧木。对于老龄酸枣树可在休眠期进行平茬,待萌发出新枝后再行嫁接,以提高嫁接成活率。选用生长健壮砧木,在距地面5～10厘米处,选平直 Liaoxi and southern Liaoning Province, jujube rich in resources, the use of jujube rootstock grafting jujube, not only grow fast, the result is early, and less investment, quick. Therefore, there are “jujube pick jujube, mountains are treasure, do not planted without making, then hung up the date then” argument. Jujube many grafting methods, the use of single buds grafting, not only long period of grafting, high survival rate, but also easy to operate, saving labor. 1 grafting: May to September, jujube tree acidity from the beginning until the skin can be grafted, grafting period of about 150 days. 2 stock processing; selection of 5-year-old, more than 1 cm in diameter young jujube trees do rootstocks. Jujube for the elderly can be stubble in the dormant period, to be sprouted after the new branch grafting, in order to improve the survival rate of grafting. Use robust rootstock growth, at a distance of 5 to 10 cm from the ground, choose flat
