7月24日以来,受“麦德姆”台风影响,江苏各地普降中到大雨。据天气信息,今后一段时间仍以阴转多云和雷雨天气为主,空气湿度大。国家水稻产业技术体系南京综合试验站站长王才林研究员提醒:这种阴雨、高湿天气,加上目前水稻正值分蘖盛期,适合稻瘟病和纹枯病发生,近期要加强田间发病情况的监控,注意防治稻瘟病和纹枯病。尤其是丘陵山区地势低洼和稻瘟病菌源多的田块以及群体大的高产田块,要特别注意防治这两种病害。稻瘟病可在水稻整个生育期造成危害,分苗瘟、叶瘟、节瘟、穗颈瘟和谷粒瘟等不同类型,以叶瘟、穗颈瘟危害最为严 Since July 24, affected by the typhoon Madame, all over Jiangsu have plummeted to heavy rains. According to the weather information, cloudy weather and thunderstorm will prevail in the future for some time and the air humidity will be high. Researcher Wang Cai-lin, director of Nanjing National Experimental Station of National Rice Industry Technology System, reminded that this rainy and humid weather coupled with the current positive tillering stage of rice is suitable for the occurrence of rice blast and sheath blight. In the near future, the monitoring of field incidence should be strengthened , Pay attention to the prevention and control of rice blast and sheath blight. In particular, hilly and low-lying low-lying and Magnaporthe grisea source of many plots and large groups of high yield plots, with special attention to control these two diseases. Rice blast can cause harm in the whole growth period of rice, and it is different in different types such as seedling blast, leaf blast, festival blast, panicle blast and grain blast, and the most harmful is leaf blast and panicle blast
