| 摘 要： | 对水稻纹枯病不同发病程度与水稻产量损失关系的灰色关联度分析结果表明，水稻纹枯病对穗实粒数影响最大，其次是结实率和千粒重，这是引起产量损失的主要原因，同时对株高，穗长也有一定的影响。

| Abstract: | In the paper, studied on the grey relational grade analysis of the different disease incidence to rice sheath blight disease and rice yield damage. The results showed that the effective spike grain numbers are influenced by rice sheath blight disease, secondly by setting percentage and 1000-seeds-wt. which are the main reasons for yield damage, meanwhile influenced to plant height and spike length. |
