【摘要】 在查阅1970～2004年国内外大量旱作农田水肥耦合研究资料的基础上,重点对其中30篇进行了分析总结。综合评述了旱作农田水肥效应关系、水肥对作物生长和产量的影响、不同水肥条件对作物水分利用效率(WUE)的影响、施肥对农田生态环境的影响以及水肥耦合模型和研究方法等研究进展情况。指出今后水肥耦合研究应该加强施肥对农产品品质和生态环境的影响的研究,同时依据不同试验目的选用田间试验或模拟试验,注重构建通用性的水肥耦合模型。更多还原

【Abstract】 Water and fertilizer, as well as their coupling effects are the main decisive factors to yield of crops on dry land. This paper summarizes the main research progress in the aspects of the relationship between water and fertilizer on dry land; the effects of water and fertilizer on growth, yield and water use efficiency (WUE); the impacts of fertilization on ecological environment and quality of agricultural products, as well as the models of water and fertilizer coupling and the research approaches. Furthermore, it proposes the study fields needed to be strengthened in the future: the impacts of fertilization on the quality of agricultural products and ecological environment, the selection of field and simulating experiments according to the research purposes, and the development of more universal models of water and fertilizer coupling.更多还原
