| 中文摘要: |
| 针对2014年以来六盘水市猕猴桃病害日益严重的问题，分别于2015年10月、2016年4月及8月对六盘水市共12个乡镇26个代表性猕猴桃栽培园区病害进行了调查。采集了大量典型病害样本, 综合生物学特性、分子鉴定及致病力测试对分离得到的病原菌进行鉴定。结果表明, 六盘水市猕猴桃夏季和秋冬季病害主要为细菌性溃疡病和真菌性软腐病、灰斑病、褐斑病，其次是炭疽病和黑斑病，春季部分园区有细菌性溃疡病，真菌病害相对较轻。本文研究结果为六盘水市猕猴桃病害的预测预报及综合防治提供了理论依据。 |
| 英文摘要: |
| Considering the increasing disease problems of kiwifruit in Liupanshui City, the kiwifruit diseases were investigated in 26 representative kiwifruit orchards of 12 townships in October 2015, April and August 2016, respectively. A number of samples with typical disease symptoms were collected and the pathogens were identified. The results of biological characteristics analysis, molecular identification and pathogenicity tests of the isolated pathogens indicated that the main kiwifruit diseases in Liupanshui in summer, autumn and winter were bacterial canker disease, postharvest soft rot, grey leaf spot and brown leaf spot, followed by anthracnose and black spot. In spring, fungal disease of kiwifruit was lightly occurred, and bacterial canker disease was also found in some orchards. Our results provide a theoretical basis for forecasting and integrated control of kiwifruit disease in Liupanshui City. |
