黑龙港区小麦玉米农艺节水技术集成模式综合评价及推广建议

黑龙港属华北缺水低平原区，水资源不足是限制该区农业生产发展的主要因素。该区主要种植模式为冬小麦－夏玉米一年两熟制，小麦、玉米高产主要靠超采地下水来维持。近年来，随着小麦节水技术的推广应用，粮田产量和水分效率在逐步提高，但节水高产潜力仍然巨大。特别是从周年水资源高效利用出发，建立区域特色的两熟一体化节水高效技术模式，十分必要。运用熵权综合评价法对“黑龙港及鲁北平原区小麦玉米减蒸降耗农艺节水技术集成与示范”项目形成的小麦玉米农艺节水技术集成模式进行评价，筛选出最佳的节水技术模式。得到的结论是：最少水肥投入模式最优，节水省肥模式次优，传统高水肥模式最差。节水省肥是未来发展现代农业的方向。应该进一步提高农户农业节水意识，利用多种手段，促进农户采用小麦玉米节水技术优化模式。

Comprehensive Evaluation and Promotion Suggestion of Wheat/corn Agronomic Water-saving Technology Integration Model in Heilonggang Region

Heilonggang water shortage is a major factor to limit the development of agricultural production in this area.The main planting model is winter wheat and summer maize double cropping in this area,wheat/cornyield depends mainly on exploitation of groundwater to maintain.In recent years,with the popularization and application of wheat water-saving techniques,grain yield and water efficiency gradually improved,but wateryield potential is still huge.In particular,it is very necessary starting from the an nivers...
