基于土壤养分丰缺指标的多区间测土配方系统的设计与实践

The Design and Practic of Multi Interval Soil Testing and Prescription System Based on Soil Nutrients Abundance and Deficiency Index

测土配方施肥对提高农业生产效率,提高粮食单产有着重要的意义。该文设计了一个基于土壤养分丰缺指标的多区间测土配方肥生产系统,并从硬件结构设计、系统架构设计、软硬件通信设计、作物施肥专家库构建等方面对测土配方系统进行了阐述。在河南省数十个乡镇土肥站实际运行使用结果表明,系统达到了预期目标,取得了较好的经济效益和社会效益。

Formula fertilization by soil testing to improve the efficiency of agricultural production, has an important significance to improve the grain yield. This paper describes the design of a multi interval soil testing and prescription production system based on soil nutrients abundance and deficiency index, and from the aspect of hardware design, system architecture design, software and hardware design of communication, crop fertilization expert database construction on soil testing system are introduced. In Henan, dozens of villages and towns dohi stations running results showed, the system has achieved the anticipated target, and achieved good economic benefit and social benefit.
