五针松的繁殖,采用实生育苗,其成苗困难,变异大,生长速度较慢。除非因育种需要,一般不宜采用。历来国内沿用大黑松靠接或用2—3年生黑松苗腹接,已成为五针松繁殖的主要手段。但鉴于五针松的靠接和腹接的苗期管理复杂,生长也不快,为此我们试验采用五针松的休眠枝劈接,以除其弊。现将方法介绍如下。一、砧木选译:以黑松为宜,因黑松根系发达,移植成活率高,生长快,适应性强;黑松用于嫁接五 Five needle pine propagation, the use of seedling growth, its seedling difficulties, variation, growth slower. Unless breeding needs, generally should not be used. Has always been followed by the domestic use of large black pine or 2 - 3-year-old black pine seedlings, has become the main means of Pinus tabulaeformis breeding. However, in view of the Pinus sylvestris L. abutted and abdomen seedling management complex, growth is not fast, for which we test the use of pine needles dormant branch cleavage, in addition to its disadvantages. Now the method described below. First, rootstock selection and translation: black pine is appropriate, due to the developed root system of black pine, transplant survival rate, rapid growth, adaptability; black pine for grafting five
