摘要
对兴安落叶松开展 PT菌根剂在育苗技术上的应用研究表明 ,人工芽苗截根接种 PT菌根剂可明显提高兴安落叶松苗木的苗高、地径生长量 ,增加根系体积。
The PT-mycorrhizal agent was applied to growing-seedling technology of Larix gmelinii. was studied. The results showed that inoculating artificial ratoon into PT-mycorrhizal agent can obviously raise the seedling highth, ground-stem sampling and root volume. The growing-seedling period may greatly shortened, by the way of raising mycorrhizal seedlings in green house and transplanting bud seedlings in the field.
