莒南县是一个水资源较为匮乏的山丘区农业大县,农业灌溉以大水漫灌为主,水资源浪费现象较为严重。发展节水灌溉农业存在政府投入不足,投资渠道分散,管理水平较低,农民节水意识淡薄,节水技术应用单一,新技术和新设备推广力度小等问题。今后需要加强对农业节水工作的领导,大力推进工程节水,积极开发新水源,加大中低产田改造力度,推广农艺生物节水技术,理顺农业水价,提高节水意识,拓宽融资渠道,改革现行管理和运行机制,高效利用农业灌溉用水。
Junan County is a large agricultural area in a hilly area where water resources are scarce. Irrigation is dominated by large-scale flood irrigation and water resources waste is more serious. The development of water-saving irrigated agriculture has problems of insufficient government investment, diversified investment channels, low management level, weak awareness of water saving by farmers, single application of water saving technologies, and the promotion of new technologies and new equipment. In the future, it is necessary to strengthen leadership over water saving in agriculture, vigorously promote water conservation in projects, actively develop new water sources, intensify efforts to reform low- and middle-yielding fields, popularize agro-biological water-saving technologies, rationalize agricultural water prices, raise water conservation awareness and broaden financing channels , Reform the current management and operation mechanism, and make efficient use of agricultural irrigation water.
