1988年7月至1989年5月,作者对喀麦隆主要水稻种植区的水稻病害进行了调查,并分析了这些病害的危害性。一般来说,有灌溉条件的地区病害严重度低于山区,但不同种植区域之间存在很大差异。北部地区的病害发生率较低,这和那里的土壤肥沃、风速大及湿度小有关。西部山区气候条件对病害发生有利。Mbo 平原的气候条件适于筛选抗稻瘟病的水稻品种。Ndop 平原适于筛选抗鞘腐病、颖片退色病的水稻品种。
From July 1988 to May 1989, the authors investigated rice diseases in Cameroon’s major rice-growing areas and analyzed the dangers of these diseases. In general, the severity of disease in areas with irrigation conditions is lower than in mountainous areas, but there is a big difference between the different planting areas. The northern part of the disease incidence is low, which is fertile soil, wind speed and humidity is small. The western mountainous climatic conditions are good for disease occurrence. The climatic conditions of the Mbo plain are suitable for screening rice varieties resistant to rice blast. The Ndop plain is suitable for screening rice varieties resistant to sheath rot and glume fade.
