雪松属松科,常绿乔木,是珍贵的用材树和观赏树种。有公园五大松之称,是园林绿化的上好树种。多生长在温暖多雨的南方各省。近年来我们由江苏等地引进了一些3—5年生的雪松苗木,因不适应我区寒冷气候,加之管理不当,结果都先后死亡。为此我们采用了播种育苗方法,使幼苗逐步适应环境,获得了较好的效果。1984年春播种,出苗71株,出苗率达95％,保存率达87％。1985年移出室外50株,越冬保存41株,保存率为82％。1986年越冬后保存37株,保存率90％。目前苗木生 Cedars, Pinaceae, evergreen trees, is a precious timber and ornamental tree species. Park known as the five pine, is a good species of landscaping. Grow more in the warm and rainy southern provinces. In recent years, we introduced a number of cedar seedlings aged 3 to 5 years from Jiangsu and other places, because they do not adapt to the cold climate in our region, combined with improper management, the results have died. To this end, we have adopted a method of sowing seedlings, so that seedlings gradually adapt to the environment, obtained good results. In the spring of 1984, 71 seedlings were germinated with the emergence rate of 95% and the preservation rate of 87%. Out of outdoor 50 in 1985, overwintering preservation of 41, the preservation rate of 82%. After the winter of 1986 preserved 37, the preservation rate of 90%. The current seedlings Health
