| 摘 要： | 通过水稻秸秆还田小区试验，初步探讨了多年秸秆还田对15个水稻品种病害的影响。试验结果表明：秸秆还田的老稻田15个水稻品种的稻瘟病、鞘腐病、纹枯病的病情指数都高于对照稻田的病情指数。黑龙江省农垦总局建三江分局主栽品种空育131，叶瘟病情指数增加了2．3％，穗颈瘟增加了2．6％，鞘腐病增加了2．2％，纹枯病增加了0．4％。

| Abstract: | The effect of rice straw returned to field in many years on the occurrence of major diseases of 15 rice varieties was studied through field plots experiment. The results indicated that the disease indexes of rice blast （Magnaporthe grisea）, sheath blight （Rhizoctonia solani） and sheath rot disease （Sarocladium oryzae） of 15 rice varieties in field with rice straw returned were higher than those of control field. Disease of rice leaf blast, neck blast, rice sheath blight and rice sheath rot disease of Kongyu 131, the main planted rice variety in Jiansanjiang Land Reclamation Bureau, were increased by2.3%, 2.6%, 2.2% and0.4%. |
