稻田节水与水肥一体化的分析探索——以浙江杭嘉湖平原为例

为推动农田节水与水肥一体化技术在浙江农业中的应用与发展，笔者以杭嘉湖平原稻田为例，分析了浙江水资源状况、农田节水与水肥一体化的意义，探索分析稻田节水的主要途径与方法。研究结果得出：农田可采用价格低廉且对水质要求低的常压软管灌溉系统实现节水节肥，并提出了稻田的水肥技术方案。开展稻田节水与水肥一体化技术，即适应现代农业简约、规模经营需求，又有助于实现农业的节水减排增效和防洪排涝，减少农业面源污染，将是“五水共治”工程在浙江农业领域中的具体应用和体现。

Farmland Water-saving and Integrated Management of Water and Fertilizer:Taking Hangjiahu Plain Paddy Field as an Example

In order to promote the application and development of farmland water-saving and the integration of water and fertilizer in Zhejiang, Hangjiahu plain paddy field was used as an example, the situation of water resources in Zhejiang Province, the significance of farmland water-saving and the integration of water and fertilizer were analyzed, and the main ways and methods of paddy field water-saving were explored. The results showed that water-saving could be realized by the use of atmospheric pressure tube irrigation system, which was cheap and had low water quality requirement, and the water-fertilizer technical proposal was also put forward. To carry out farmland water-saving and water-fertilizer integration technology could be in accordance with the simple and scale management of modern agriculture, and contribute to water-saving, emission reduction, efficiency increase and flood control and drainage in agricultural production, and reduce agricultural non-point source pollution. The technology would be the specific application and embodiment of the'comprehensive water treatment'project in agricultural fields of Zhejiang Province.
