近年来，随着计算机和3G等网络通讯技术的快速发展，物联网技术日益成熟并迅速应用到农业生产、科研等各个领域中。将物联网技术应用到农业领域，有效促进了传统农业向现代农业的转变。笔者回顾了物联网概念的形成过程，综述了物联网在设施农业、作物病虫害远程诊断、精准灌溉和农田环境监测等方面的研究进展以及4 个方面的应用现状。分析了中国农业物联网发展亟需解决的几个主要问题，并针对性地给出了农业物联网未来发展的相应措施。最后对中国农业互联网的发展前景进行了展望，指出农业物联网是中国未来农业发展的方向。

In recent years, with the fast- growing of computer and 3G network technology, the Internet of Things (IOT) becomes increasingly mature and has been quickly applied to various fields of agricultural production, scientific research etc. The technology of IOT applied to the field of agriculture effectively romoted the transformation of aditional agriculture to modern agriculture. The forming process of the concept of IOT was reviewed. Research progress of IOT in facility agriculture, crop pest remote diagnosis, precision irrigation and farmland environment monitoring were summarized in this paper, and the application status of four aspects of IOT was also discussed. Some main problems to be solved in the development of agricultural IOT in China were analyzed and the corresponding measures were put forward. Finally, the development prospects of agricultural IOT in China were forecasted and agricultural IOT was highlighted as the future development direction of agriculture in China.
