寒地水稻主要病害调查研究

Investigation on Major Rice Diseases in Cold Area

2008年,黑龙江省农垦科学院植物保护研究所组织水稻植保科研人员对宝泉岭、红兴隆、建三江、牡丹江、齐齐哈尔和绥化等6个分局有代表性农场进行稻瘟病、鞘腐病、纹枯病和褐变穗等病害调查,结果表明:稻瘟病和褐变穗病情指数较低,没有发现大面积严重发生稻瘟病的地块;纹枯病发生已比较普遍,各农场纹枯病发生程度有一定差异;少数农场鞘腐病发生严重,对水稻产量有一定影响。

The major rice diseases infection such as blast, sheath rot, sheath blight and brown ear were investigated six farms including Baoquanling, Hongxinglong, Jiansanjiang, Mudanjiang, Qiqihar and Suihua in 2008. The investigation results showed that the infection indexes of blast and brown ear were lower and the sheath blight occurred in large area and the infection varied at different area. Sheath rot occurred seriously in some farms and affected yield to some extent.
