针对传统设施农业水肥利用效率低、信息采集量少、数据挖掘利用弱等问题,设计了基于两线解码技术和云计算的设施农业水肥一体化智能云灌溉系统,包括智能云灌溉控制系统、全自动水肥一体机和高效节水灌溉系统3部分。该系统通过两线解码技术,利用各种传感器实时采集各单个设施农业作物生长环境的参数信息,并将各类采集数据及时传输和存储于数据管理云平台,根据设施农业种植区采取的环境信息和作物的需水需肥规律,利用云集群的计算和分析能力,科学确定设施农业中不同环境条件下作物生长的水肥需求和灌溉施肥制度,实现水肥一体化的智能控制。通过2个设施农业种植基地的应用实例表明,相比传统灌溉方式,水分和肥料的利用率分别提高了25%~40%和15%~35%,并且大幅度减少了劳动时间和劳动力。

In order to solve the problem in traditional protected agriculture,namely the inefficient use of water and fertilizer,less information collection,weak capability of data mining and implementation,an intelligent cloud irrigation system was proposed based on the technology of dual-line decoding and cloud computing to integratively manage water and fertilizer for protected agriculture,which was composed of intelligent cloud irrigation control system,automatic machine of integration of water and fertilizer,water saving irrigation system with high efficient. The system via dual-line decoding technology,and a variety of sensors were used to collect the parameters of crop growth environment for each individual protected agriculture in real-time. Then all kinds of collected data were timely transmitted and stored in cloud data management platform. Thereafter,the ability of calculation and analysis from cloud calculated cluster was used,water and fertilizer needs,irrigation and fertilization system in protected agriculture under different environmental conditions for crop growth were scientifically determined to achieve intelligent control of water and fertilizer integration. The system was of great importance in guiding protected agriculture to achieve high yield,high quality,ecology and safety in production. Two application examples in planting bases of protected agriculture showed that compared with the traditional irrigation methods,the intelligent cloud irrigation system based on the technology of dual-line decoding and cloud computing to manage integrated water and fertilizer for protected agriculture can improve the water use efficiency by 25% ~40% and fertilizer use efficiency by 15% ~ 35%,which shortened labor time and decreased labor force sharply.
