摘　　要：随着我国设施农业的快速发展,越来越多的工程技术应用到设施农业中。水肥一体化技术是集合施肥与灌溉配套使用的一项新技术,在我国农业生产中,提高水肥利用效率是设施农业生产中必须解决的问题。传统农业中常采用地表上滴灌,存在管道老化、灌溉过程中存在沿程渗漏和蒸发等问题,本研究改变传统地表滴灌形式,采用地表下埋管,地表上肥料罐将水肥混合后通过滴灌管道直接输送到作物根部的灌溉方式。同时,采用传感器进行灌溉的自动控制与自动检测土壤水分信息和肥料信息,利用远程控制来实现数据传输,并通过模拟计算出灌溉计划,大大提高了灌溉施肥自动化水平。With the rapid development of facility agriculture in China,more and more engineering techniques are applied to facility agriculture.Water and fertilizer integration technology is a new technology for integrated fertilization and irrigation.In China's agricultural production,improving water and fertilizer use efficiency is a problem that must be solved in facility agricultural production.In traditional agriculture,drip irrigation is often used on the surface of the earth.There are problems of pipeline aging,seepage and evaporation in the process of irrigation.This study changes the traditional form of surface drip irrigation,and uses buried pipes under the surface.The fertilizer can be mixed through the drip pipe to the root of the crop,and the sensor is used to carry out the sensor.The automatic control of irrigation and automatic detection of soil moisture information and fertilizer information,and then through the Internet network,remote control to achieve data transmission,and then the computer through simulation calculation of irrigation plan,greatly improved the level of irrigation and fertilization automation.
