试验筛选出 10种对樟子松枯梢病病原菌Diplodiapinea有拮抗作用的真菌 ,最终确定具有拮抗作用的真菌 6种。拮抗效果由强到弱依次为绿木霉 (Trichodermaviride)、单格孢 (Ulocladiumchartarum )、枣褐霉(Spadicoidesoboratum)、镰刀菌 (Fusariumsp .)、球毛壳孢 (Chaetomiumglobosum)、附球菌 (Epicoccumsp .)。其中绿木霉效果最好 ,为首选菌种。拮抗菌的筛选以相对抑菌效果为准 ,同时应考虑被抑制率和菌种本身具有的致病性。 Ten fungi were screened out to antagonize Diplodiapinea, a pathogen of Pinus sylvestris var. Mongolica, and finally identified 6 fungi with antagonistic effects. The antagonistic effects of Trichoderma viride, Ulocladiumchartarum, Spadicoidesoboratum, Fusarium sp., Chaetomium globosum, Epicoccum sp. . Which Trichoderma best, as the preferred bacteria. Antagonistic bacteria screening relative antibacterial effect prevail, taking into account the inhibition rate and strain itself has the pathogenicity.
