摘　　要：在黑龙江哈尔滨稻田开展试验,设置翻耕深度10、20cm和30cm处理,模拟当地3种主要翻耕方式,处理后调查田间发病情况,探讨翻耕深度与稻瘟病、纹枯病发生程度之间的关系。结果显示:翻耕30 cm处理叶瘟发生率为各处理最低,病菌初侵染末期和再侵染末期分别为18.00%和75.67%;翻耕30 cm处理穗颈瘟发生率为各处理最低,病菌初侵染末期为20.33%;翻耕30 cm处理纹枯病发生率最低,病菌初侵染末期和再侵染末期分别为9.33%和22.00%。结果一致表明,翻耕30 cm所模拟的深翻耕作方式更有利于对稻瘟病和纹枯病的生态防控。The experiment was carried out in the rice field in Harbin,Heilongjiang Province.Tillage depths of 10,20,and 30 centimetres were set up to simulate the three principal tillage methods employed in the local area.The incidence of rice blast and sheath blight was investigated following the treatment,and the relationship between tillage depth and the occurrence of these two diseases was discussed.The results showed that the lowest incidence of leaf blast was observed in the 30 cm ploughing treatment,with a rate of 18.00% at the end of the initial infection and 75.67% at the end of the reinfection.The lowest incidence rate of panicle neck blast was observed in the 30 cm ploughing treatment,which was 20.33% at the end of the initial infection.The incidence rate of rice sheath blight was the lowest in the 30 cm ploughing treatment,which was 9.33% at the end of the initial infection and 22.00% at the end of reinfection.The consistent results indicated that the deep tillage method,simulated with 30 cm ploughing,was more conductive to the ecological management of rice blast and sheath blight.
