摘要
[目的]探讨拔苗和剪苗对甘薯黑痣病发生的影响。[方法]利用甘薯黑痣病带病种薯育苗，比较拔苗和剪苗对甘薯黑痣病发生的影响。[结果]拔苗栽插会将黑痣病菌携带至大田引起发病，而剪苗则可以有效地阻隔黑痣病菌，防止黑痣病的传播蔓延。[结论]试验结果为控制黑痣病传播和推广剪苗技术提供了理论依据。
Abstract
Objective] The aim was to explore effects of pulled and cut sweet potato seedlings on the occurrence of sweet potato black scurf disease.[Method] Pulled and planting could take black scurf bacteria into the field and cause sweet potato black scurf disease.The effects of pulled ( underground stem retained) and cut ( underground stem removed) sweet potato seedlings on the occurrence of sweet potato black scurf were evaluated.[Result] The cutting sweet potato plants could effectively prevent the spread of sweet potato black scurf disease.[Conclu-sion] The results provide theoretical basis for controlling the spread of sweet potato black scurf disease and promoting cutting seedling technology.
