摘 要:摸清甘薯生产过程中不同阶段的病害发生种类与发病程度,可以有针对性地开展病害防治。对廊坊及其周边地区甘薯育苗圃、大田新移栽苗和收获期薯块的病害发生种类与发生程度进行调查,结果表明:严重威胁调查区甘薯生产的病害有甘薯病毒病(SPVD)、甘薯黑斑病、甘薯茎线虫病和甘薯根腐病。其中,SPVD自2009年首次在我国发现以来已经蔓延到了所有调查地块,传播速度之快应引起甘薯行业的高度重视;其他3种甘薯传统病害也有随连作年限逐年加重的趋势。The investigation of sweet potato diseases in different growth stages could carry out disease control in a targeted way.The sweet potato disease types and occurrence degree in the seedling nursery,newly transplanting seedlings and harvesting in Langfang were investigated.The results showed that the most dangerous diseases included sweet potato virus disease(SPVD),sweet potato black rot,sweet potato stem nematode and sweet potato root rot.SPVD which was first reported in 2009 in China was found in every area investigated,and the rapid spread should be paid attention to.Other three traditional diseases were more and more seriously threatening sweet potato production,while no crop rotation had been taken.
