灌溉水与稻白叶枯病的发生发展有密切关系。各地多年来调查研究都指出:秧田受淹,本田病重;本田受涝、深灌,加重发病;且病害有随灌溉水流蔓延邻田的现象,甚至有些地方的群众称白叶枯病为“水瘴”。因而近年来,在防治上试行提出浅水勤灌,拔节期烤田,以及采取封锁病田“毒水”等措施。但迄今对水层影响发病及其原因,尚无实验证明,因而在控制灌水防病的实际应用上,如何掌握重点,提出具体要求,还缺少理论依据。江苏苏州专区农科所和中国农业科学院江苏分院在 Irrigation water is closely related to the occurrence and development of rice bacterial leaf blight. Over the years, investigations and studies all over the country have pointed out: The seedling flooded and the Honda became seriously ill. Honda was affected by floods and deep-water irrigation and aggravating the disease. The disease was accompanied by the spread of irrigation water and the phenomenon of neighboring fields. Even the people in some places called the bacterial blight “ Water 瘴. ” In recent years, therefore, measures such as shallow water dunking and jointing roasting have been tentatively put forward in prevention and control measures and measures such as “poisonous water” to block the disease have been taken. But so far the impact on the water layer and its causes, there is no experimental evidence, and therefore in the practical application of control of irrigation and disease prevention, how to master the key points, put forward specific requirements, but also lack of theoretical basis.
