| 中文摘要 | 氣候與農法系統都會影響作物病害的流行病學，然而短期實驗很難地推斷長期生態反應機制。本研究建立基於事後機率的機制模型，並利用跨越 10 年的長期數據來構建氣候變動（包含溫度、相對濕度、風速和降雨）、農法（傳統和低外部投入耕作）和作物之間的關係，以探討台灣試驗稻田的病害發生機制。本研究發現 (1) 傳統農業和低外部投入農業對稻熱病致病率的影響相似；(2) 只有在相對濕度較高的情況下，溫度升高才會對增加此病害致病率； (3) 降雨僅在最佳水平以下，才能對此病害致病率產生正向影響。綜合上述，低外部投入農業，施用較少化肥和其他可持續營養管理策略，在病害致病率方面取得了與傳統農業相似的效果，這同時也表明了氣候變動可能會淩駕農法系統對稻田真菌性致病率的影響。 |
| 英文摘要 | Both weather fluctuation and farming system influence the epidemiology of crop diseases. However, short-term experiments are difficult to mechanistically extrapolate into long-term ecological responses. Using a mechanistic model with Bayesian inference, long-term data spanning 10 years were used to construct relationships among weather fluctuation (temperature, relative humidity, wind, and rainfall), farming system (conventional and low-external-input farming), and crop disease in experimental rice fields in Taiwan. Conventional and low-external-input farming had similar influences on the disease incidence of rice blast. Temperature had a positive influence on the disease incidence only under high relative humidity. Rainfall positively affected the disease incidence until an optimum level of rainfall. Low-external-input farming, with a lower application of fertilizers and other sustainable nutrient management, achieved similar effects on the disease incidence to those achieved by conventional farming. This suggests that weather fluctuation may override the effect of the farming systems on fungal disease incidence in rice fields. |
