摘　　要：随着气候条件、种植模式、品种更新等因素变化,大豆病虫种类不断发生演变且发病频繁,防治难度增大,对大豆生产造成较大危害。文章对大豆生育期内主要病虫害特征,包括危害部位及时期、感病症状、病原物等进行总结,提出不同生育期病虫害防控重点及对策,为大豆种植过程中病虫害鉴别及病虫害防治提供理论支撑,助推大豆生产实现“扩面、增产、提质、绿色”目标。With changes in climatic conditions,planting patterns,variety updates and other factors,the varieties of soybean diseases and pests had evolved and become frequent,making it more difficult to control and causing significant harm to soybean production.This paper summarized the characteristics of main diseases and pests in soybean growth period,including the damage position and period,disease symptoms,pathogens,etc.,and put forward the key points and countermeasures for the prevention and control of diseases and pests in different growth periods,which provided theoretical support for the identification of diseases and pests and pest control in the process of soybean planting,and helped to promote soybean production to achieve the goal of"expansion,production increase,quality improvement,and green".
