山西省甘薯主要病害及防治技术研究进展

Research Progress on Main Diseases and Control Techniques of Sweet Potato in Shanxi Province

甘薯是山西省主要的杂粮作物,在农业产业发展中具有重要作用。近年来,甘薯病害种类不断增加,危害程度加重,造成新品种快速退化、产量降低,严重制约着山西省甘薯产业的发展。综述了影响山西省甘薯产量及品质的4种主要病害,即甘薯病毒病、茎线虫病、根腐病、黑斑病等及其对病原、危害症状、传播方式、防治措施等方面的研究进展,以期为控制甘薯病害发展、促进山西省甘薯产业标准化生产提供理论依据。

Sweet potato is the main cereal crop in Shanxi province,which plays an important role in the development of agricultural industry.In recent years,the variety of sweet potato diseases is increasing,the damage degree is aggravating,resulting in rapid degradation of new varieties and the reduction of yield,which seriously restricts the development of sweet potato industry in Shanxi province.In this paper,four main diseases affecting the yield and quality of sweet potato in Shanxi province were summarized,including sweet potato virus disease,stem nematode disease,root rot disease and black rot disease.The research progress of pathogen and damage symptoms,transmission mode,control measures and other aspects were summarized,which could provide a basis for the development of sweet potato disease and promoting the standardization production of sweet potato industry in Shanxi province.
