摘要
在生产上,红松苗的繁育普遍采用种子繁殖实生苗,其子代遗传多样性复杂,生长量和松籽结实量差异较大,产量不稳定。采用红松优良种源基因型较好的亲本,用低砧劈接技术嫁接,培育子代性状一致的优良嫁接苗,对实现果材兼用用材林和经济林有着突出的经济效益、社会效益和生态效益。试验结果表明,嫁接时期以5月25日成活率最高,不同嫁接方法以低位劈接较好,施肥量以磷酸二铵+硫铵+硫酸钾(1∶1∶1)其地径生长量和新梢生长量最高。
Pinus koraiensis commonly used their seeds to breed seedlings in production ; genetic diversity of progenies of Pinus koraiensis are complex;their growth ＆ fruit bearing amount have significant differences;their cost are instability. Using optimal superior provenance genotypes parents of Pinus koraiensis, taking technology of cleft grafting on low rootstock to cultivate superior grafting plant with fit progeny traits, prominent economic, social ＆ ecological benefits were obtained on the realization of timber plantation for fruit and timber forest ＆ cash crop ; among different grafting methods cleft grafting on low rootstock is the optimal. Result shows that： the optimal grafting date is May 25th;the growth of the ground diameter ＆ the young sprout are the most highest while the fertilizing amount is diammonium phosphate＋ ammonium sulfate ＋ potassium sulfate（1 ： 1 ： 1）.
