摘　　要：[目的]为鉴定水稻品种对白叶枯病的抗性提供理论依据。[方法]以152个水稻品种为试材,分别采用剪叶接种法和喷雾接种法对其接种水稻白叶枯病菌,研究接种方法对水稻抗病性鉴定的影响。[结果]除高感品种外,喷雾接种水稻的发病情况轻于剪叶接种;喷雾接种一次可达到多个品种抗性鉴定的目的,接种到调查约30d的时间足以使病菌进行多次侵染,但该接种方法成败的关键在于喷雾后立即捆扎稻丛3d。[结论]喷雾接种法可满足水稻品种抗性鉴定的技术要求,并大大降低鉴定的工作量。[Objective] The study was to provide theoretical basis for identifying the resistance of rice varieties to rice bacterial blight.[Method] With 152 rice varieties as the tested materials,they were inoculated with rice bacterial blight by leaf-cutting inoculation and spray inoculation resp.Then the effects of inoculation methods on the disease-resistance identification of rice were researched.[Result] Except for high sensitive varieties,the disease status of rice inoculated by spray inoculation was lighter than that of rice inoculated by leaf-cutting inoculation.The resistance identifications of multiple varieties could be achieved by one spray inoculation.There was about 30 d from inoculation to investigation,it was enough for multiple infections of pathogens.But the essential key of spray inoculation was immediately binding of rice plant hill for 3 d since spray.[Conclusion] Spray inoculation could satisfy the technical demand of resistance identification of rice varieties and reduce workload greatly.
