| 摘 要： | 根据稻曲病对水稻的为害特点，对不同病粒稻株与水稻产量损失的关系进行灰色关联度分析。结果表明，稻曲病对水稻结实率下降的影响最大，这是引起产量损失的主要原因；其次，对每穗总粒数、穗长、剑叶长、千粒重、株高也有一定的影响。

| Abstract: | Based on the damage feature of flase smut to rice, the relationship between the plants with different infected grains and the losses of yield was analysed by using gray relational grade. The results showed that flase smut affected the seed setting percentage of rice decreased most significantly,which was the major cause for the yield loss. Flase smut also affected the total grains per ear, ear length, uppermost leaf length, weight of a thousand grains and plant height in certain degrees. |
