接种环

方法：在玻片上将细菌与碱液混合，用接种环或接种针往上挑，观察有无丝状物出现，我们把它叫作细菌拉丝实验。

Method : put the cultivated bacteria and a drop of alkaline liquid together on a piece of glass , mixed thoroughly with inoculation loop or needle , and observed the appearance of a thread like substance when the loop or needle was drawn upward .

火炬松育苗试验结果表明：火炬松大田育苗最佳的处理组合为苗木密度100~150株/m2、芽苗截根处理以保留芽苗主根长的50%、接种厚环乳牛肝菌Sg；

The seedling experimentation of Pinus taeda was studied . The best combination of seedling was that the seedling density 100 ~ 150 trees / m ~ 2 , retaining half of the main root length of a seedling , and artificial inoculation of Suillus grevillei .

接种厚环乳牛肝菌的油松生长明显低于前三种处理。

Inoculation of Ectomycorrhizal Fungus Suillus grevillei strains of Pinus tabulaeformis growth was significantly lower than the previous three kinds of treatment .
