【省水利厅】宝鸡峡引渭灌区进入冬灌高峰期
Shan Xi Ri Bao· 2026-01-06 23:02
该中心提早谋划,抓实水源保障。提前开展墒情研判与水情预测,在灌前完成水库蓄水工作。组织 各级管理人员下沉一线,建立墒情与苗情台账,实施分类指导、按需供水,精准把握灌溉时机,夯实小 麦越冬丰产基础。强化设施整修维护,抢抓灌前水利施工黄金期,集中推进灌区"三修两清一绿化"、重 点工程维修及常态化养护工作,对渠道、水工建筑物、机电设备等进行全方位拉网式整修,确保输水和 设备安全稳定运行。面对河源来水逐步递减的情况,制定精细化配水方案,严格遵循"以渠济库、以库 补渠、渠库结合"的思路,最大限度盘活水资源存量,不断提升水资源利用效率与效益,全力满足灌区 冬灌用水需求。 同时,灌区不断优化灌溉服务,持续推进农业水价综合改革。严格落实水价流动公示、超定额累进 加价、分类水价试点及节水奖励等政策,积极推广二维码计量收费服务,构建起"计量精准、收费透 明、管理高效、监管有力"的闭环管理模式。 "我们组建专业浇地服务队,针对无劳力、外出务工农户推出'代浇代灌'服务,全方位提升灌区服 务效能。近期,严格落实24小时值班巡查,加密巡查频次,及时处置各类安全隐患,全力守护冬灌安 全。"陕西省宝鸡峡引渭灌溉中心相关负责人说。(记者:徐颖 ...
