江西早稻稻瘟病气象风险区划研究

采用植保部门20世纪90年代以来的病虫害资料和气象部门的同期气象资料,从稻瘟病病菌致病所要求的气象条件出发,选取温度、湿度、降水、日照等气象因子,建立了江西省早稻稻瘟病发生发展风险区划指标,得出了赣北、赣中早稻稻瘟病风险较大,赣南相对较小的结论。

Study on the Regionalization of Meteorological Risk for Rice Blast of Early Rice in Jiangxi Province

Using the plant diseases and insect pests data from plant protection units since 1990s and the meteorological data from weather units in the same period,starting from the meteorological conditions demanded by the bacteria of rice blast,the meteorological factors such as temperature,humidity,precipitation and sunlight were selected to establish the regionalization indices of rice blast risk in early rice in Jiangxi Province.The conclusion was drawn that the rice blast risk in north and middle Jiangxi was greater and that in south Jiangxi was comparatively less.
