樟子松改接红松营建高效坚果生态林技术

Construction Technology of Efficient Nut Ecological Forest by Grafting Pinus sylvestris var.mongolica with Pinus koraiensis

樟子松改接红松是兴安盟林业科学研究所通过多年探索、实践,总结出的生态林改良技术,利用砧木和接穗的相互诱导和培养,表现各自优良的遗传特性,即利用樟子松抗旱、抗寒、速生的优良特性,结合红松经济价值高的特性,培育速生丰产的优质苗木。作者认为,通过异砧改接能够将兴安盟地区樟子松从生态型防护林转型为生态经济型防护林,为引种地常绿针叶树种的结构调整、扩充资源、丰富造林树种的多样性开辟一条新的途径,从而使营林达到生态、经济、社会多效目的。

The grafting of Pinus sylvestris var.mongolica onto Pinus koraiensis is an efficient ecological forest improvement technology developed by the Forestry Science Research Institute of Xing'an League through years of exploration and practice.It utilizes the mutual induction and cultivation of rootstocks and scions to exhibit their respective excellent genetic characteristics,namely,the excellent drought resistance,cold resistance,and rapid growth of Pinus sylvestris var.mongolica,combined with the high economic value of Pinus koraiensis,to cultivate high-quality seedlings with rapid growth and high yield.The author believes that through cross rootstock grafting technology,the Pinus sylvestris var.mongolica in Xing'an League can be transformed from an ecological protective forest to an ecological and economic protective forest,expanding resources for the structural adjustment of evergreen coniferous tree species in the introduction area,open up a new path to enrich the diversity of afforestation tree species,and achieving ecological,economic,and social benefits in afforestation.
