| 摘 要： | 为更系统地了解我国马铃薯四大产区病虫害发生情况,通过对2008—2017年《全国植保专业统计资料》进行汇总,本文重点分析我国马铃薯四大产区北方一作区、中原二作区、西南混作区和南方冬作区的晚疫病、早疫病、蚜虫、蛴螬等病虫害发生及防控情况,并对各产区间的相关指标进行比较分析。结果表明:马铃薯四大产区病虫害发生危害情况不同,晚疫病作为马铃薯最主要病害之一,高发于北方一作区和西南混作区,造成年均产量损失分别占各区总损失的42.41%和64.22%,远高于其它病虫害;中原二作区马铃薯病虫害种类繁多,且均对产量造成威胁。在四大产区中,北方一作区年均病虫害发生面积最大,实际产量损失最高,二者均超出该产区种植面积占比。当前,马铃薯四大产区病虫害防控仍太过依赖化学农药,应进一步推进病虫害绿色防控技术的研发和推广,加快病虫害专业化统防统治与绿色防控技术的融合。

| Abstract: | In order to understand the occurrence and control of pests and diseases in four major potatoproducing areas in China, the National Plant Protection Statistics (2008-2017) was summarized to ana-lyze and compare the occurrence and control of potato late blight, potato early blight, aphids, grubs, etc. in four major potato-producing areas in China (North region, Central Plain region, Southwest region and South region). The results illustrated that the occurrence of pests and diseases was different among various potato-producing areas. As the number one killer of potato, potato late blight occurred frequent-ly in North region and Southwest region, and the average losses accounted for 42.41% and 64.22% of the total annual losses in each area, much higher than those caused by other diseases and pests. There were many threatening diseases and pests in Central Plain region. The North region exhibited the largest occurrence area of pests and diseases and the highest actual loss among the four producing areas, which exceeded its proportion in planting areas. The control of diseases and pests still relied too much on the chemical control, so the development and extension of green crop pest control techniques should be ac-celerated and the fusion of regional pest control program and green crop pest control should be promoted. |
