摘要
通过对影响山杏嫁接成活的一些主要技术环节进行研究，结果表明：在高寒干旱山区，杏树接穗应在３月未展花蕾时采取，直径以０．５～１．０ｃｍ为宜，低温保存，在砧木处于落花期时进行嫁接；嫁接后应用塑料袋完全套住接穗，１０ｄ后破袋，３０ｄ后取袋，６０ｄ松绑，可提高成活率；在８月下旬对接穗进行摘心处理，９月上旬摘叶处理，可明显提高嫁接越冬的保存率。
By studying some important technical steps of grafting of prunus armoniaca ,the results indicated that the graft should be picked at the end of march. Its diameter is about 0.5～1.0 cm and should be kept under low temperature. The best grafting period is at the fallen flowers phase of the grafting stock. After grafting is finished, following steps are necessary:wrapping graft with plastic bag, breaking the bag after 10 days of grafting, taking it away at 30 days, releasing the belts after 60 days. The results also show that the best way to increase survival rate after the winter is plucking heart at the last 10 days of August and pucking felioge at the early 10 days of Sept.
