| 中文摘要: |
| 本文根据作物水盐动态响应函数，分析了作物生长与土壤水盐运动关系，建立了节水、控盐、高产灌溉制度优化设计模型，为节水灌溉和微咸水利用提供了决策依据。实例分析表明，本文提供的模型及方法是合理的；实施节水、控盐灌溉制度能带来明显的经济效益和环境效益。 |
| 英文摘要: |
| Based on the dynamic response model of crop to water salinity,the relation between crop growing and soil salt movement is analyzed.The optimal design model of irrigation schedule for high yield,water saving and salinity control is proposed.It helps to promote the management of water saving and utilization of poor quality water.Case study shows that the model is reasonable and practical,the percentage of fresh water saved is 31.1% and the crop yield is optimized. |
