| 中文摘要 | 本研究引用由隸屬於國際開發總署之國際農業技術轉移基標網路計畫(IBSNT)與美國密西根大學合作發展之玉米生長模式(CERES MAIZE),經驗證後可作為今後臺灣用水及灌溉計畫之參考。CERES MAIZE模式已經由中興大學土壤系研究證實其於臺灣之適用性,但該研究著重於作物適栽性之研討而較忽略水管理部份之考慮,本研究延續其研討,著重水管理部份之研討與校正。本計畫之目的在於藉由模式以瞭解如遇缺水情況時供水量與作物生長和產量之關係,並模擬作物在各個生長時期的缺水與產量降低之關係,探討在缺水時期,有限水資源之最佳分配方式,並據以擬定相關之灌溉計畫,期能以有限之供水量充分有效利用,使缺水損失降至最低,以期達到水資源之最佳利用目標。 |
| 英文摘要 | The crop model for maize (CERES MAIZE) from IBSNT was introduced. The model was developed under the project of International Benchmark Sites Network for Agro-technology Transfer, (IBSANT). CERES MAIZE has been studied at the Soil Department, Chung-Hsin University for the analysis of optimal land use for different crops. The results showed that is can be used effectively to model the growth of maize in Taiwan. If not enough water is spilled to the root zone for crop use, the crop may suffer from stress due to high soil moisture tension. Damage may occurs if that stress is too high or lasts too long. The relationship between water deficit and yield decrease are different in various growth stages. The crop may be more sensitive in some growth stage than others. This study concentrated on the water management part of the CERES MAIZE model for the knowledge of relation between crop yield and water applied. Some field experiment data from the Shui-Chia experiment station at Taiwan were used for the validation and calibration of the model. The crop model was used to understand the crop yield response to the water deficit in different growth stages. These knowledge can be then used for drought allocation when drought occurs for optimal use of the limited water supply. |
