摘　　要：对北美蓝云杉和欧洲云杉从有性繁殖和无性繁殖2个方面进行育苗技术的研究,结果表明:无论是撒播还是条播,2种云杉的出苗率均较高,其均值都达到90%以上,但采用宽幅条播的播种方式,更利于2种云杉幼苗的保存。扦插基质和激素可以有效提高2种云杉的扦插生根率和根系效果指数,进而改变云杉根系的质量,提高云杉种植成活率。Based on the research on the sexual reproduction abies, the results show that Picea pungens and Picea abies broadcast and drill. It can be beneficial to preserving the and asexual reproduction for Picea pungens and Picea have higher emergence rate over than 90 percent for seedlings of Picea pungens and Picea abies by use of drill seeding in broad width. The cutting medium and hormone can effectively improve the rooting rate of cutting and root effect index of Picea pungens and Picea abies, and then can change the root quality and raise the survival rate.
