中文摘要 | 本研究主要目的,在探討台灣西北區兩期作水稻白葉枯病盛行率與春秋季氣候之關係,並利用其關係建立盛行率預測之模式。分析結果顯示,氣候之變異對白葉枯病盛行率有影響。第一期作水稻白葉枯病盛行率與3月之降水量及降水日數呈正相關,與4、5月相對濕度呈負相關。第二期作水稻白葉枯病盛行率與氣候變數之單相關性,未達5%顯著水準。利用迴歸法建立兩期作之白葉枯病預測模式,各模式解釋變異程度均在百分之八十以上。 |
英文摘要 | The influence of spring and fall climatic variation on the prevalence of rice bacterial blight disease during 1967-1990 was studied by the correlation and regression analysis. In the first crop season, disease prevalence was positively correlated with March precipitation and number of precipitation days, negatively correlated with April and May relative humidity. No significant simple correlation between disease prevalence and climatic factors for the second crop season was observed at 5% level. Two forecasting models were developed for two crop seasons. Coefficients of determination indicated that the climatic variables accounted for 80% above of variation in disease prevalence. |
