水肥一体化技术借助微灌系统,把肥料溶解在灌溉水中,以水为载体,由灌溉管道输送给田间作物,实现水肥同时供应,在土壤中以优化组合状态满足作物生长发育的需要。这项技术分为简易水肥一体化技术和智能水肥一体化技术,能够实现水肥同步管理,提高肥料利用率,节省肥料、劳动力和生产成本。一、系统组成水肥一体化系统主要由微灌系统(包括水源、首部工程、输水管网、灌水
Water and fertilizer integration technology with micro-irrigation system, the fertilizer dissolved in irrigation water, water as a carrier, irrigation pipelines to the field crops, water and fertilizer supply at the same time, in the soil to optimize the combination of state to meet the needs of crop growth and development. The technology is divided into a simple integration of water and fertilizer technology and intelligent water and fertilizer integration technology, to achieve synchronous management of water and fertilizer to improve fertilizer utilization, saving fertilizer, labor and production costs. First, the system composed of water and fertilizer integrated system consists of micro-irrigation system (including water sources, the first project, water pipe network, irrigation
