典型井灌区农田节水技术模式多目标综合评价

Multi-goal evaluation on the water-saving agricultural technique-mode in the typical area of well-irrigation

在调查研究的基础上 ,总结了在河北省景县农业灌溉生产中存在的七种农业技术模式 ,并运用多目标综合评价方法对七种技术模式进行了综合评价。结果得出 ,抗旱品种 +“小白龙”输水+大田畦灌 +小麦、玉米水肥耦合技术模式得分值最高 ,可成为适合于景县农业灌溉的最佳综合技术模式。喷灌虽然有其技术优势 ,但综合效果仍然较低 ,在短时间内不可能成为当地大面积节水灌溉农业的主导技术模式。表 4 ,参 6。

Based on the investigation,seven water-saving agricultural technique modes were proposed.As a result of the multi-goal evaluation on the seven modes,the seventh mode maybe the best one for Jingxian county to develop the water-saving agriculture in the future,for the value got from the evaluation was the highest.though the sprinkling irrigation has its own predominance,this kind of irrigation technique mode can't be widely extended at present
