摘要
2013与2014年对东北地区(黑龙江省与吉林省)与华北地区(河北省、内蒙古自治区)的紫花苜蓿病害进行了调查。此次调查在东北地区共发现紫花苜蓿病害14种,其中黑龙江省12种,吉林省10种;在华北地区共发现紫花苜蓿病害17种,其中河北省10种,内蒙古自治区13种。东北地区在生产中易大面积发生且危害较严重的病害主要有5种,分别为褐斑病、春季黑茎与叶斑病、匍柄霉叶斑病、霜霉病、镰刀菌根腐病,7-8月为病害高发期。华北地区各调查点病害种类差异较大,内蒙古自治区危害较严重的病害主要有5种,分别为霜霉病、锈病、匍柄霉叶斑病、春季黑茎与叶斑病、尖孢镰刀菌根腐病,发病高峰期为6-9月;河北省廊坊市危害较严重的病害主要有6种,分别为褐斑病、锈病、匍柄霉叶斑病、春季黑茎与叶斑病、木贼镰刀菌根腐病、炭疽病,发病高峰期为7-10月;河北省张家口市危害较严重的病害主要有4种,分别为霜霉病、褐斑病、锈病、春季黑茎与叶斑病,发病高峰期为6-10月。
Alfalfa diseases in Northeast China (Heilongjiang and Jilin Provinces)and North China (Hebei Prov-ince and the Inner Mongolia Autonomous Region)were investigated in 2013 and 2014.Fourteen alfalfa diseases were found in Northeast China,12 in Heilongjiang Province and 10 in Jilin Province,and 17 diseases were found in North China,10 in Hebei Province and 13 in Inner Mongolia.Common leaf spot,spring black stem and leaf spot,stemphylium leaf spot,downy mildew and Fusarium root rot were the five most prevalent disea-ses that would cause serious plant damage in Northeast China.The occurrence of these diseases peaked in July and August.Major differences existed in the disease varieties found at each investigation site in North China. There were five major diseases (downy mildew,rust,stemphylium leaf spot,spring black stem and leaf spot and Fusarium oxysporum root rot)which would cause serious damage in Inner Mongolia,especially when their occurrence peaked from June to September.Six diseases (common leaf spot,rust,stemphylium leaf spot,spring black stem and leaf spot,Fusarium equisetum root rot and anthracnose)were found in Langfang City and four (downy mildew,common leaf spot,rust and spring black stem and leaf spot)in Zhangjiakou City of Hebei Province.These diseases would cause serious damage,especially when their occurrence peaked from July to October for Langfang City and from June to October for Zhangjiakou City.
