地下水是天津郊县农业的主要水源,井灌面积已达148万亩。由于井渠配套不合理,既耗能又费水,单井灌溉效益不高,平均单井控制灌溉面积仅为52.6亩。为此,对现有井灌区挖潜改造,加速井渠配套建设,提高井灌水平,建设节水型灌区,是当前农业生产急待解 Groundwater is the main source of agriculture in rural areas in Tianjin, irrigation area has reached 1.48 million mu. Due to unreasonable well-channel facilities, both energy consumption and water consumption, single-well irrigation is not profitable, and the average single-well-controlled irrigation area is only 52.6 mu.
