摘要
随着我国经济的发展,农业用水面临巨大挑战,提升北方地区农田水分利用效率对解决粮食生产过程中的缺水问题至关重要。全面分析了耕作保墒、覆盖保墒、增施有机肥与秸秆还田、水肥耦合、调整作物布局、选用节水型品种和化学调控等农艺节水技术措施的研究进展与发展趋势。针对我国农艺节水技术措施已取得的成就与存在的问题,提出了农艺节水中一些重要的理论问题和关键技术,以期将农艺节水技术提升一个新的高度。
With the economic development in China, the agricultural water use faces enormous challenges, and therefore the en- hancement of utilization efficiency of farmland water use in northern China is essential to solve the water shortage problem dur ing the food production process. In this paper, the research progress and development trend of the agronomic water-saving tech nology measures are analyzed, including the tillage for soil moisture conservation, covering for soil moisture conservation, organ ic fertilizer and crop straw returning to soil, coupling of water and fertilizer, adjustment of crop layout, selection of wate-saving varieties, and chemical control. In light of the achievements and existing problems on the agronomic water-saving technology measures, some important theoretical problems and key technologies on the agronomic water-saving are proposed, which can help improve the agronomic water-saving technology to a new height.
