摘　　要：物联网是当今研究的一个热门技术,我国作为农业大国,在现代化大农业的发展中,物联网技术在智慧农业中得到很好的应用。认知无线电是一类智能无线通信技术,能够通过对周边环境的感知而发现空闲的可用频谱资源,从而提高频谱利用率。将农业物联网与认知无线电技术相结合,能够缓解农业物联网所面临的频谱资源紧张问题。分析了物联网频谱研究涉及的方面和频谱管理的现状,将认知无线电频谱感知技术应用到农业物联网环境中,研究基于认知的农业物联网的网络架构,提出了认知无线电技术在农业物联网中应用带来的挑战。Internet of Things （IOT） becomes a hot technology for the research, as an agricultural country, IOT technology is widely used in intelligent agriculture for the development of modern agriculture. Cognitive radio is a kind of intelligent wireless communication technology, which can sense and find the available idle spectrum resources through the surrounding environment, so as to improve the spectrum utilization rate, The combination of the lOT in Agricultural and cognitive radio technology can alleviate the shortage of spectrum resources of IOT are analyzed in agricultural. The spectrum management and spectrum research in IOT, spectrum sensing technology of the cognitive radio is applied to IOT in agricultural environment, the network architecture of IOT in agrieuhural based on cognitive radio is studied, the application challenge for the cognitive radio technology in agriculture lOT is analyzed.
