植物泡囊丛枝菌根及其应用展望

The plant arbuscular mycorrhiza and prospects of its application

摘要: 阐述了植物泡囊丛枝菌根(VA菌根)的形态特征、对植物的营养作用及其与根瘤菌等微生物的关系，分析了环境条件、栽培管理和耕作制度等对VA菌根的影响。提出应加强VA菌根的基础研究，试验接种外来菌源以及利用土壤的原有菌源，以充分利用VA菌根这一潜在的生物资源使农作物持续稳定增产。

Abstract: The morphologic characteristics of arbuscular mycorrhiza (VAM),its nutrient function and its relation with other microorganisms such as nodule bacteria are discussed.Environmental factors,cultivated managements and rotation systems affecting VAM are also analyzed.The authors advance that VAM potential resource should be fully utilized through strengthing basic reseach,inoculating exernal VAM fungus resource and making use of original VAM fungus resource for sustainable increase of crop output.
