在齐齐哈尔地区与种源地气候条件比较基础上，进行了钻天松的引种，并针对其种子繁殖后代变异较大的特点，开展了用樟子松作砧木进行嫁接繁殖试验，试验结果表明，在齐齐哈尔地区引种钻天松是可行的。为了尽快培育大量的钻天松苗木，可以用樟子松3年生容器苗作砧木，采集1年生钻天松嫩枝进行嫁接，平均嫁接成活率为73．5％。

Compared with climatic conditions between Qiqihar region and provenance, Pinus sylvestris var. fastigiata （ Carr. ） were introduced. According to characteristics （ a large progeny variation in the seed production） of Pinus sylvestris var. fastigiata （carr） ,grafting experiments were conducted by using Pinus sylvestris var. mongolica as stock. Result shows that introduction of Pinus sylvestris var. fastigiata （carr） Q. F. Anet is possible. In order to cultivate large seedlings of Pi- nus sylvestris var. fastigiata（ carr ） Q. F. Anet, three-year-old Pinus sylvestris var. mongolica were used as stock;softwood of one-year-old Pinus sylvestris var. fastigiata Q. F. Anet were grafted;the mean grafting ratio are 73.5%.
