| Abstract: | Based on the water resources and fertilizer use investigation,the problems of irrigation and drainage system(IDS)in our agricultural water conservancy are pointed out;i.e.drought and water shortage,non-point source pollution,low water utilization,and no matched projects.Some hotspots in high efficient utilization of water resources and fertilizer of irrigation area are followed,which needed to further research.These studies are significant to enrich the theories of high efficient utilization of water resources and fertilizer and IDS management,and to supervise the exactitude control of IDS to get the best crop yield,economic efficiency,and ecological environment benefit by using least water and fertilizer. |
