红松嫁接樟子松植株后期管理技术研究

Study on Late Stage Management Technology of Plant of Grafting of Pinus Sylvestris

该文以塞罕坝地区樟子松作砧木嫁接红松植株为研究对象,通过对嫁接成活的红松接穗的后期管理,重点是越冬防寒技术措施,有效提高接穗成活率。采取草+膜、草+棉、布+膜、膜+棉4种防寒措施对来自3个不同区域的红松接穗进行对比试验,结果表明,草+膜的防寒措施的植株保存率远远高于其他方式,而取自宽城和丹东红松接穗性状表现好于茅荆坝的。研究旨在为调整塞罕坝地区树种结构,改善资源状况,增加物种多样性,同时为红松异砧嫁接技术研究提供理论依据和试验指导。

By grafting of Pinus koraiensis to Pinus sylvestris plants in Saihanba area, through the management of grafting survival rate of Pinus koraiensis scions of late, with a focus on overwintering technology measures and effectively improving the survival rate, grass ＋ membrane, grass ＋ cotton, cloth ＋ membrane, membrane＋cotton four kinds of cold proof measures from three different areas of Pinus koralensis scion were compared. Results show that, preservation rate of grass＋membrane of cold proof measures is much higher than other ways, scion of Pinus koraiensis traits in Zikuan and Dandong is heifer than those in Maojingba.This study is intended for the adjustment of Saihanba tree structure to improve the condition of the resources, increse the species diversity,as well as provide theoretical basis and experimental guidance for grafting of Pinus koraiensis technology research.
