山西省北部彰武松引种试验初报

Introduction Experiments of Pinus densiflora var zhangwuensis in Northern Shanxi

以辽宁省彰武县的彰武松为接穗,油松和樟子松为砧木,在山西省北部风沙区进行了引种试验。结果表明,彰武松在山西省北部风沙区嫁接成活率平均为77.5%,以樟子松为砧木的嫁接成活率高于以油松为砧木的。嫁接后3年高生长表现优良,以樟子松为砧木的生长量普遍高于以油松为砧木的,抗逆性表现优良。

Pinus densiflora var zhangwuensis was introduced from Zhangwu county in northern Liaoning to wind sandy area of northern Shanxi. Graft survival rate and growth of Pinus densiflora var zhangwuensis were investigated to study its adaptabili- ty. Results showed that its graft survival rate and growth were more than Pinus tabulaeformis and Pinus sylvestris and it had excellent stress resistance to show that Pinus densiflora var zhangwuensis was suitable in wind sandy area of northern Shanxi.
