水稻纹枯病病情调查与损失估计
On Rice Sheath Blight Investigation and Yield Loss Estimation
【摘要】 通过对水稻纹枯病的株发病率、病斑高率、穴发病率与病情指数间的相关分析,证明株发病率、病斑高率始终与病情指数呈高度正相关。并提出对藤系138的病害损失估计公式。
【Abstract】 By correlation analysis between ratio of infected plant, ratio of highest infected spot to plant highnss, ratio of infected hole and disease index of rice sheath blight, we found that ratio of infected plant, ratio of highest infected spot to plant highness were highly positive correlative to disease index, and deduced yield loss formla of Teng Xi 138 caused by rice sheath blight.
