摘要
通过人工红松嫁接培育红松经济果林,红松果成熟年限大大提前,其结实年龄比天然红松可提早20年以上。建设红松经济果林工程,增加目的树种比例与优良种源,既能提高森林生态功能,增加森林面积和森林蓄积,还能产出大量的红松果实,创造巨大的经济效益。
Through artificial Pinus koraiensis Sieb.et Zucc.grafting to cultivate economic fruit forest of Pinus koraiensis Sieb.et Zucc.,the mature age of Pinus koraiensis Sieb.et Zucc.cones is greatly advanced,and its fruiting age can be more than 20 years earlier than that of natural Pinus koraiensis Sieb.et Zucc..Constructing Pinus koraiensis Sieb.et Zucc.economic fruit forest project and increasing the proportion of target tree species and good provenance can not only improve the ecological function of the forest,and increase the forest area and forest accumulation,but also produce a large number of Pinus koraiensis Sieb.et Zucc.fruits,and create huge economic benefits.
