摘　　要：近年来,甘薯作为保健食品和功能性食品深受消费者的喜爱,种植效益高,成为部分地区重要的经济作物之一,但随着连年连片规模化种植和种薯种苗的跨区域调运,致使甘薯病毒病危害逐年加重,特别是甘薯病毒病害(SPVD)已成为甘薯产业健康持续发展的最大制约因素。文章就SPVD的分布范围、病害症状、病原、发生规律及检测方法进行了阐述,并提出了相应的防治措施,以期为实际工作提供参考。In recent years,sweetpotatoes have been well received by consumers as health and functional foods.They have high planting efficiency and become one of the important cash crops in some regions.Large-area continuous cropping and cross-regional transportation of sweetpotato seedlings have caused the disease of sweetpotato virus to increase year by year,especially the sweet potato virus disease(SPVD)has become the biggest constraint on the healthy and sustainable development of the sweetpotato industry.This paper describes the distribution range,symptoms,causal agents,disease cycle and epidemiology,and detection methods of SPVD,and puts forward corresponding management in order to provide a reference for practical work.
