摘　　要：红松(Pinus koraiensis)是东北地区重要的坚果树种之一,目前红松果林建设成为东北地区重点发展的经济林之一。为红松果林建设提供优质壮苗是目前研究的重要课题。在培育红松樟子松异砧嫁接苗试验中,通过对春季3个不同嫁接时间的研究得出结论,牡丹江地区的嫁接育苗在4月15日以前最好,应当尽量提前在树液流动之前进行,有利于接口愈合,促进苗木生长。The Korean pine(Pinus koraiensis) is one of the important tree for nuts in northeast China.In the current,the development of the economic forest in northeast China was focused on the development of Korean pine forest.Providing high quality and stronger seedlings for the Korean pine forest is one of the core research.The cultivation of Korean pine intergenetic grafting seedlings were studied at three different grafting time in spring,the results showed that the best grafting time was before April 15th and before the sap flowing in the Mudanjiang area.It was propitious to the interface healing and promoting seedlings growth.
