摘要
本文根据湖北稻白叶枯病的发生发展史,结合湖北水稻种植区划、农业地理环境、气象要素等,将湖北稻白叶枯病的发生区域划分为四类,即江汉平原病害生态区、鄂东丘陵病害生态区、鄂中丘陵岗地病害生态区、鄂西山地病害生态区;着重分析了各病害生态区白叶枯病发生流行特点及原因,提出了相应的防治对策。
This project started with the collection of data on the fluctuation of rice blight, the rice planting districts, the local agricultural conditions and the key element of meteorology in Hubei province. Analysis of the data classified Hubei into four geographical regions in terms of occurrence of rice blight: 1) the Jianghan plain, 2) the hill country area of eastern Hubei, 3) the hillock region of central Hubei, and 4) the mountain areas in western Hubei. In this paper, the characteristics and possible causes of prevalence of rice blight in different geographical regions were discussed with respect to countermeasures of control.
