影响红松嫁接成活因素的探讨

Discussion on Impact Factors of Korean Pine Grafted

通过试验研究认为,嫁接时期、嫁接方法、接穗长度、嫁接方位及接口包扎材料等对红松嫁接成活率均有影响。在辽宁地区,红松嫁接较适宜的时间为5月下旬至6月上旬,成活率可达90%以上;髓心形成层对接法成活率最高,成活率达65%以上,可以作为首选方法;砧木以东、西方位做切面较好,成活率达88%以上;接穗长度为8 cm左右,成活率达88%;包扎材料以塑料条最好,成活率达94%。

The Study showed that grafted period, methods, the length of material of interface binder and so on could affect the grafted survival the scion, grafted orientation, the rate of korean pine. In Liaoning provinee, the appropriate time of korean pine grafted was in late May to early June, grafted survival rate more than 90%. pith joint cambium method could be used as preferred method that grafted survival rate more than 65%. The batter orientation of rootstock plane were east and west that grafted survival rate more than 88%. Scion length 8 em that grafted survival rate more than 88%. Plastic interface binder was the best that couht make grafted survival rate more than 94%.
