摘　　要：以作物生长施肥过程为研究对象,对不同土壤条件中的作物生长信息进行数据分析,建立一种智能化变量施肥决策控制系统。以作物叶绿素和作物生长信息之间的相互关系为依据,对有限空间范围内的相关环境参数数据进行处理,结合农田试验数据,形成基于土壤肥力和作物叶绿素的两种施肥模型。使用系统开发工具,建立基于数据分析技术的变量施肥决策控制系统,与传统施肥模式下的作物产量、增产率、肥料增效率以及肥料贡献率等数据进行对比,表明建立的变量施肥决策控制系统具有较好的推广性。This paper takes the intelligent management system in agricultural production process as the research object,through the analysis of data acquisition,transmission,analysis and the generation and transmission process of control instructions in the intelligent management system,designs an agricultural intelligent management system which communicates through 5g network technology.Agricultural intelligent management data acquisition system can effectively collect and transmit environmental information,analyze and process environmental parameter information.Intelligent management system compares data information with knowledge data,gives alarm prompt,and generates control instructions according to database information.Data transmission network sends control instructions,and drives control system.The driving of mechanical equipment in the area makes the environment information in the intelligent system management area in a stable state.
