近5年来,水稻生理性青枯在江苏省稻麦连作区连续发生,在水稻灌浆期对水稻的危害较大,进而影响水稻产量.通过对宿迁市近几年气象资料及相关资料综合分析,认为导致水稻生理性青枯的重要因子为寒流突至致使气温骤降,其次是植株抗逆性差.因而提出防御水稻生理性青枯应加强栽培管理,促进水稻根系活力,并关注气温变化,适时灌水保温、喷施叶面肥保根促灌浆、完善农业保险等措施.
近5年來,水稻生理性青枯在江囌省稻麥連作區連續髮生,在水稻灌漿期對水稻的危害較大,進而影響水稻產量.通過對宿遷市近幾年氣象資料及相關資料綜閤分析,認為導緻水稻生理性青枯的重要因子為寒流突至緻使氣溫驟降,其次是植株抗逆性差.因而提齣防禦水稻生理性青枯應加彊栽培管理,促進水稻根繫活力,併關註氣溫變化,適時灌水保溫、噴施葉麵肥保根促灌漿、完善農業保險等措施.

@@@@Rice physiologically Bacterial wilt has been occurring at rice-wheat continunous cropping areas in Jiangsu Province in recently 5 years. It is one of main diseases the grain-filling stage that affects the yield of rice. Based on analyzing the meteorological data of Suqian City, it was suggested that sudden drop temperature and the plant stress resistance were the first and the second reason which caused rice physiological Bacterial wilt. It is proposed that the methods to enhance the rice defense to the physiological Bacterial wilt should strengthen management, promote the activity of rice root system, and pay attention to the change of temperature, thermal insulation, and improve the agriculture insurance and other measures during rice grain-filling period.
