塞罕坝地区红松嫁接技术研究

Study on Grafting Techniques of Pinus koraiensis in Saihan Dam Area

以樟子松为砧木、红松为接穗,研究不同砧木年龄、接穗类型以及嫁接高度对红松嫁接效果的影响。结果表明:塞罕坝地区以3年生的樟子松容器苗作为砧木嫁接苗其成活率最高,为60.4%;在复壮苗上采穗并随采随嫁接,成活率达87%;在主枝高度140～159cm、侧枝高度210～229cm时嫁接,效果最好。

This paper studied the effects of age of rootstock,types of scion and grafting height in the Pinus koraiensis grafting test based on the scion of Pinus sylvestris var..The results show that:In Saihan Dam area,the grafting survival rate was the highest that was 60.4%with the rootstock of the 3-year-old container seedlings of Pinus sylvestris var..Survival rate can reach 87%by using scion from seedling rejuvenation,and Immediately grafting after picking the scion.Effect of grafting were the best when it was grafted from the main branch from 140 to 159 centimeter and the lateral branch from 210 to 229 centimeter.
