笔者根据各稻作区的气候特点、耕作栽培水平及各稻作区水稻纹枯病的发生特点和流行规律,并结合今后我国农业生产发展情况,对今后5—10年我国各主要稻作区水稻纹枯病发生流行趋势进行了分析、探讨。认为在今后五年内,我国水稻纹枯病的发生面积将逐年增加,病情严重度和产量损失呈波浪式上升,在低纬度、低海拔、高产栽培地区将是水稻病害中危害最严重的病害;在今后5—10年后,其发生面积有所增加,病情严重度增加的速率渐趋缓慢,实际产量损失仍有增加的趋势,但其增加速率也将日趋减小。各稻作区由于气候条件,栽培水平等因素的差异,稻纹粘病发生流行趋势各有其特点,一般南方稻作区重于北方
According to the climatic characteristics, cultivation and cultivation of paddy fields and the occurrence and prevalence of rice sheath blight in paddy fields, combined with the future development of China’s agricultural production, the author of the rice paddy area of our country in the next 5-10 years The epidemic trend of rice sheath blight was analyzed and discussed. In the next five years, the occurrence area of rice sheath blight in our country will increase year by year, and the seriousness of the disease and the loss of yield will increase in a wave way. It will be the most harmful disease in rice diseases in low latitude, low altitude and high yield cultivation areas; In the next 5-10 years, its occurrence area will increase, the rate of increase of disease severity will become slower and the actual yield loss will still increase, but the rate of increase will also decrease. The paddy area due to climatic conditions, the level of cultivation and other factors, rice grain sticky disease epidemic trends have their own characteristics, the general southern rice area heavier than the north
