Application of Broccoli Residues to Soil can Suppress Verticillium Wilt of Cotton by Regulating the Bacterial Community Structure of Rhizosphere

Cotton verticillium wilt was effectively controlled by application of broccoli residues (BR) return to soil.The disease incidences of cotton cultivars with different verticillium wilt resistant levels were determined under BR treatment, and the defence mechanism against verticillium wilt by BR treatment was analyzed based on bacterial community structure of cotton rhizosphere,, in order to provide guidance for screening the effective biocontrol bacteria.

施用西兰花残体（Broccoli Residues, BR）还田可有效防治棉花黄萎病。本研究测定了不同抗黄萎病等级的棉花品种在BR处理下的病情发病率，并基于棉花根际细菌群落结构，解析了BR处理防治棉花黄萎病的防御机制，以期为高效生防细菌的筛选提供理论指导。
