| 摘 要： | 为系统全面地了解马铃薯晚疫病在我国的发生演变特征及防控情况，基于2008—2017年国家统计局官方数据、《中国农业统计资料》《全国植保专业统计资料》及全国马铃薯品种分布等数据，对全国及各马铃薯产区晚疫病的发生及防治情况进行综合量化分析。结果表明：马铃薯晚疫病在我国连年发生，年平均发生面积约197.47万hm2，占马铃薯总种植面积的40.66%；晚疫病造成马铃薯年平均产量损失占所有病害所致产量损失的63.54%，远高于其他病害，损失巨大；在我国马铃薯4大产区中，马铃薯晚疫病在北方一作区的年平均发生面积最大，约73.44万hm2，而在西南混作区造成的年平均产量损失最高，约14.29万t；晚疫病发生与马铃薯种植区域的重心在空间上呈现相似的迁移趋势；以费乌瑞它为代表的高感晚疫病品种在全国大面积种植，但近年来部分抗病品种的种植面积正在逐年增加；近年来我国对马铃薯晚疫病的防治面积大幅度提升，但仍太过依赖化学防治，应加大绿色防控技术的推广和应用力度。

| Abstract: | In order to systematically and comprehensively analyze the occurrence characteristics of potato late blight in China in recent years, the occurrence and control of late blight in major potato farming regions of China were quantified based on the official data from National Bureau of Statistics (2008- 2017), China Agriculture Statistical Report, National Plant Protection Statistics, and the distribution of potato varieties, etc. The results showed that late blight occurred every year in the last ten years, on an average annual acreage of 197.47×104 hm2, accounting for 40.66% of the total national potato planting acreage. The average annual yield loss caused by late blight was huge, accounting for 63.54% of potato yield losses caused by all diseases. Among the four farming regions, the northern region had the largest annual occurrence acreage of about 73.44×104 hm2, and the southwestern region had the highest average annual yield loss of about 14.29×104 tons. The distribution of late blight occurrence changed in a similar trend to that of the potato planting areas. The susceptible varieties Favorite as a representative, were still planted in a large area across the country, but in recent years, some resistant varieties have been planted with an increasing area. The control of late blight in China has been greatly improved in recent years, but it still relied too much on chemical application. Therefore, the application of green control technologies should be strengthened. |
