Abstract:

In China,huge amount of organic wastes is produced annually and it contains large quantity of nutrients and might serve as an important resource to enhance ecological services in agroecosystem. Aerobic fermentation is a widely used method for the treatment of organic waste and resource transformation,and composting may inhibit many plant diseases. In this review,we summarized recent progress in the mechanism of the disease suppressive of composts,focusing on its regulatory effects on the structures and functions of rhizosphere microbiome as well as potential regulatory pathways. We discussed the differences between composting microbiome and soil rhizosphere microbiome,effects of composting on soil biological and physicochemical properties,and biological and abiotic environmental factors on rhizosphere microbiome. This relevant summary might provide some primary understanding of the interaction system among compost,soil and plant rhizosphere microbiome.

Key words: compost, plant diseases, disease suppressing, soil/rhizosphere microbiome
