Root Exudates and Their Effects on Plant Rhizosphere Soil Micro-ecology Environment

The root of plant is an important organ conferring material and energy exchange between plant and outside environment,and study root exudates have very important significance to clear the interaction between plants and environment.In this paper,root exudates related contents in recent years were summerized,which including components,producing approach,affecting factors of root exudates and their effects on plant growth and plant rhizosphere micro-ecology.Finally,methods and directions of root exudates study in the future were expected.
