在温室接种试验基础上 ,对蓝桉混合菌根人工合成、接种效应进行了研究。根系显微观察表明 ,真菌组合在蓝桉根系上形成混合菌根 ,即 LA [(Laccaria lateritia)× (Acaulospora laevis) ],本试验对接种后菌根合成、菌根真菌间的交互作用进行了研究 ,试验证明 :光壁无梗囊霉感染率(相对总根数 )呈下降趋势 ,同时 ,蜡蘑菌在根系上的合成逐渐增加 Based on the greenhouse inoculation test, the synthetic effects of the mixed eucalyptus mycorrhizal fungi, inoculation effects were studied. The root microscopic observation showed that the fungal combination formed a mixed mycorrhizal fungi (LA [(Laccaria lateritia) × (Acaulospora laevis)] on the roots of A. eucalyptus, and the interaction between mycorrhizal inoculation and mycorrhizal fungi Studies and experiments show that the infection rates (relative total number) of S. gonorrhoeae on the light-wall are declining, while the synthesis of waxy mushroom on the root system is gradually increased
