| 摘 要： | 针对海河低平原水资源严重不足，干旱日趋加剧的现状，以节水为主线，以提高水分利用效率为中心，以节水增产增收为目的，系统研究了限水灌溉农田土壤水分消长动态，主要作物生长发育特点、需肥需水规律及水肥配合原则。在节水种植机理研究的基础上，又系统研究了调整作物布局，优化种植方式，筛选抗旱喜肥型品种，调控水肥运用，采取抗旱节水耕作措施等，形成限水灌溉农田节水种植系列技术，产量稳定提高，水分利用效率提高1倍左右。

| Abstract: | In the light of the existing status of shortage of water resources and increasingly intensified drought in Haihe Lowland Plain,systematic studies were carried out on water dynamics of the limited irrigation farmland,growth and development of the main crops and their fertilizer and water repuirements as well as fertilizer-water combination principles,Through adjusting crop distribution,optimizing cropping patterns,selecting anti-drought and fertilizer-adaptable varieties,using water and fertilizer monitoring and implementing tillage practices for anti-drought and water-saving and ect.,a series of techniques for approaches on limited irrigation were developed with yield stably increased and water use efficiency doubled. |
