短枝嫁接技术是松类无性繁殖技术的突破,具有如下特点:与常规嫁接相比可提高繁殖系数40～60倍[6];成活率、荫条率及成苗率分别在90%、85%、70%以上;操作技术简易;适于繁殖成龄优树;嫁接苗生长正常,并可提前开花结实;生产成本低,为常规枝接苗的1/5.此技术已用于油松种子园建设,效果良好.介绍到国外在欧洲赤松上初试成功,受到国外同行好评.
Spur grafting technology is a breakthrough of pine asexual propagation technology, has the following characteristics: Compared with conventional grafting can improve the breeding coefficient of 40 to 60 times [6]; survival rate, shade rate and seedling rate were 90%, 85 %, More than 70%; operation technique is simple; suitable for breeding age-superior trees; grafted seedlings grow normally, and can flowering and fruiting ahead of schedule; production cost is low, the conventional branch seedlings 1 / 5. This technology has been used for Pinus tabulaeformis Seed orchard construction, the effect is good. Introduced to abroad in the Japanese red pine on the first successful test, praised by foreign counterparts.
