在北方,引用高含沙浑水进行淤灌,不仅是充分利用水沙资源,挖掘现有水利设施潜力,缓和夏灌期间缺水矛盾,起到抗旱保苗、改土治碱、增肥,促进农业增产的重要措施,而且也为处理多沙河流和减少入黄泥沙开创了新的途径。据陕西省泾惠渠、洛惠渠及宝鸡峡三大灌区近年来对引洪淤灌工作在平原地区大规模、大面积、长距离的自流引灌,对高原地区试验性抽浑淤灌及对水库灌区处理水库泥沙引浑淤田的资料统计,
In the north, it is not only making full use of water and sediment resources, digging the potential of existing water conservancy facilities, alleviating the water shortage contradiction during summer irrigation, playing a role in drought relief, soil improvement and alkali control, fertilization and promotion An important measure to increase agricultural output, but also opened up new avenues for handling the Dousha River and reducing sediment into the Yellow River. According to the large-scale, large-area and long-distance gravity-fed dredging with flood-irrigation and silting irrigation in the plain areas, Jinghuiqu, Luohui and Baojixia in Shaanxi Province in recent years, According to the statistics of treating muddy silt caused by reservoirs in reservoir irrigation area,
