区域农田土壤墒情监测与精量灌溉技术研究

Research on regional farmland soil moisture monitoring and precision irrigation technology

为了推行节水农业,利用GSM网络通讯技术,在田间采集土壤动态水分信息,由田间过程控制和上位计算机决策控制级组成的集散控制系统完成对区域农田土壤的墒情监测和灌溉管理,使农田、果园、林地的农作物和树木生产在最佳的灌溉环境下获得最佳的节水效果。

In order to carry out water-saving agriculture, the soil moisture data were collected by means of GSM network communication technology, and the soil moisture monitoring and irrigation management of regional farmland were materialized by the total distributed control system made up of field process control and decision-making control of upper computer, and thus crop and tree produc- tion of farmland, orchards and forest land could be carried out under both the optimal irrigated condi- tions and the best water-saving effect.
