| 摘 要： | 通过对条纹叶枯病不同病情与产量损失关系的研究,初步探明了水稻条纹叶枯病对产量的影响,病株率(x)与产量损失率(y)之间的关系为正相关,回归方程为y=1.06 0.84x(R=0.9278)。据此提出水稻条纹叶枯病的防治指标为病株率3%。

| Abstract: | The effect of rice stripe blight on rice yield was revealed by studing on th e correlation between the disease in dexes and rice yield losses.The results sh owed that the disease d index(x)was positively correlated with the r ate of yield losses(y),the r egression equation was y=1.06 0.84x(R=0.9278 ** ).Based on the study,the economic thr eshold for controlling rice stripe blight was proposed as th e 3%diseased plants. |
