摘要
本研究针对北美兰云杉植物在pHS-9的碱性土壤上育苗其出苗率和保苗率低，且生长缓慢，原有森林培育技术难以有效地解决这一生产上的实际难题，试图采用菌根化生物技术进行育苗，对其进行了14个菌根菌的育苗应用研究。在同一种源不同菌种层次上进行优良外生菌根的筛选，综合生长指标进行评价。
Because of low rate of emergence and rate of preservation of Picea pungens planted in alkaline soil with pH value at 8-9, the original cultivating technology can＇t effectively solve the practical problem. This study tries to cultivate seedling by use of mycorrhiza biological technology and makes research on 14 kinds of mycorrhizal fungus. Choice of fine exotrophic mycorrhiza has been done at different levels for the same fungus species.
