| 摘 要： | 为了提高从日本引进的抗松材线虫病的黑松和赤松优良家系在引种地新环境下的成活和生长能力,2005～2006年对松树抗性家系开展了优良外生菌根菌肥的施用试验.连续跟踪调查发现,抗性赤松和黑松9个家系施用Be菌肥后,大部分家系的苗高和地径生长量比对照提高或显著提高;5种外生菌根菌剂(Ap、La、Be、Pt1和Pt2)对抗性黑松的促生作用显著,对地径的促生效果优于苗高,且各菌根菌肥间的促生作用差异不明显;对3种菌根菌(Be、La、Rl)的固体菌剂和泥浆菌刺进行施用效果比较,表明Rl使用泥浆菌剂蘸根施用效果优于固体菌剂直接施用;Be和La则因家系不同效果有所不同.总体来看抗性黑松和赤松采用菌根化造林明显提高了松树生长量.

| Abstract: | To increase the growth of the Pinus densiflora and P.thunbergii family trees resistant-Bursaphelenchus xylophilus(pine wood nematode) introduced from Japan,some of ectomycorrhizal fungi(EMF) strains were inoculated to the pine trees during 2005 to 2006.The results showed that,among the nine P.densiflora and P.thunbergii family trees treated with Be,the average height and diameter of most family trees were increased significantly compared with the control.The EMF strain Ap,La,Be,Pt1 and Pt2 significantly imp... |
