针叶树嫁接对于培养母树林和种子园以及培育特形城镇绿化树种很有用处,但是针叶树嫁接往往成活率很低。我们用冬芽夏接技术解决了这一难题,落叶松嫁接成活率为95%,云杉嫁接成活率为87%,樟子松嫁接成活率为83%。一、选择母树用于培养母树林和种子园嫁接时,按照选优树的方法选择母树。用于城镇绿化大苗的嫁接,选择冠形优美的植株作为母树。塞罕坝机械林场科研所选择出垂枝落叶松、龙头落叶松、圆头云杉、圆头樟子松等多个城镇绿化树种。
Coniferous grafting can be useful for growing mother trees and seed orchards, as well as for cultivating greenery in special towns, but conifers often have low survival rates. We tackled this problem with winter bud summer harvesting techniques. Survival rate was 95% for larch grafting, 87% for spruce grafting, and 83% for Pinus sylvestris. First, select the mother tree used to cultivate mother tree and seed garden grafting, according to the method of selecting the best tree selection mother tree. For the grafting of green seedlings in the town, choose the crown of beautiful plants as the mother tree. Saihanba mechanical forest research institutes choose hanging larch, leading larch, round head spruce, round Pinus sylvestris and other urban greening species.
