| 摘 要： | 菌根真菌与根际微生物间的关系及其对宿主植物的影响是近年来菌根研究的一个热点问题。影响菌根形成、发育和功能的主要根际因子有根系分泌物、其它微生物及其与菌根真菌的相互作用（拮抗作用或刺激作用）。菌根真菌与土壤微生物混合接种对宿主的生长和营养有积极意义。VA菌根真菌由于可大大改善宿主植物的磷营养状况，促进根瘤的形成，因而与根瘤菌混合接种可对宿主植物不但在生长方面，而且在抗逆生理方面产生积极的影响。国内外对VA菌根与外生菌根混合接种的研究，多集中在两种菌根的关系及其对林木生长的影响方面，但有关菌根混合接种对林木营养、抗逆生理的影响，则很少有人研究。近年来，对菌根真菌与放线菌及其他根际微生物关系的研究也逐渐受到人们的关注。

| Abstract: | One of the focus problems of mycorrhizal researches has been laid on the relationships between mycorrhizal fungi and microbe of rhizosphere and their influences on host plant. The key factors influenceing development and function of mycorrhiza include secretion of root system, other microbes and association among mycorrhizal fungi (antagonism or stimulation). It was demonstrated that growth and nutrient status of the host plants could be bettered when they were mixed inoculated by mycorrhizal fungi and other soil microbes. The phosphate nutrient status of the host plants were more bettered by fungi of VA mycorrhiza, so that formation of root nodule was stimulated. Therefore, the mixed inoculation of VAM fungi and nodule bacterium could better not only growth of the host plant, but also the physiological characteristics of the host plant. Researches of mixed inoculation of VA and ecto mycorrhizal fungi have been focused on the association between the two fungi and their influence on growth of forest trees. Up to now, there were a few of researches on the influence of mixed inoculation of the mycorrhizal fungi on nutrient status and physiological resistance of forest tree. In recent years, people have been interesting in the researches on association among mycorrhizal fungi, actinomyces and other soil microbes. |
