| 中文摘要 | 水稻為提供全球人口的基本糧食，然而隨著極端天氣事件頻繁發生，農產業的供水穩定度降低，糧食的供給穩定成為目前待解決的問題之一。使用科技產品輔助判釋水稻植體水分狀態，將有助於進行農業水資源精準管理。本研究結果指出，隨著水稻乾旱程度增加，水稻的SPAD值與葉綠素含量愈低。利用紅外線熱像儀拍攝乾旱初期的水稻植株可以發現，雖然RGB影像中無明顯差異，但生理參數與植體溫度已與慣行栽培具有顯著差異。利用植體溫度與大氣溫度所計算出的作物水分逆境指數 (CWSI)，與植體相對水分狀態及生理參數間相關性高。利用CWSI與植體相對水分狀態進行迴歸分析結果，其校正後決定係數為0.86。藉由紅外線熱影像儀可以即早判斷水稻缺水狀態，協助農民進行田間灌溉用水規劃，達到水資源精準管理運用之目標。 |
| 英文摘要 | Rice is a staple food for the global population. However, extreme weather events threaten the stability of the water supply for agriculture, posing a critical challenge to the stability of the food supply. The use of technology to assess the water status of rice plants enables the precise management of agricultural water resources. The results of this study reveal that rice-producing regions with more severe drought have higher ion leakage rates, lower Soil Plant Analysis Development (SPAD) meter values, and reduced total chlorophyll content in plants. Although no significant differences were observed in red-green-blue (RGB) images, physiological parameters and canopy temperature differed significantly from conventional farming when infrared thermography was used to capture rice plants in the early stages of drought. The Crop Water Stress Index (CWSI), calculated from canopy temperature and atmospheric temperature, indicated a high correlation between access to water for rice plants and their physiological parameters. Regression analysis using CWSI and plant water status yielded a corrected coefficient of determination of 0.86.Our study demonstrate that infrared thermography can effectively detect early signs of water stress in rice, aiding farmers in irrigation planning and enabling precise management and optimal utilization of water resources. |
