水稻纹枯病又叫烂脚瘟,在我区各稻区都有发生,尤以平原、丘陵地区发生较为普遍,早稻发病重于晚稻,早熟品种更为突出。发病田块减产率一般为一至三成,部分重病田块,因茎叶腐烂引起倒伏,损失可达五成以上,甚至颗粒无收。为了摸索井冈霉素防治水稻纹枯病的效果,笔者曾在进贤县五里,崇仁县下屋、郭圩,抚州市孝桥等地作了调查。现将结果整理如下。 Rice sheath blight, also known as rotten foot plague, occur in all rice areas in our region, especially in the plains and hilly areas more common occurrence of early rice is more serious than late rice, precocious varieties are more prominent. The incidence of field plots yield reduction is generally one to 30%, part of the sick plots, lodging due to stem and leaf decay, the loss of up to 50%, or even crop failure. In order to explore the effect of Jinggangmycin against rice sheath blight, I conducted a survey in Wuxili of Jinxian County, Xiawu of Chongren County, Guo Wei and Xiaoxiao of Fuzhou City.
