Agriculture and forestry internet of things generally refers to agricultural IoT technology applied in forestry. Therefore, in fact, the specificity of agriculture and forestry IoT is stronger, and it is specifically designed for forestry development. In particular, it can provide important technical support for the development of smart forestry. Then, in terms of the application of agriculture and forestry internet of things, the agriculture and forestry internet of things can be applied to those aspects of forestry management. The application of agriculture and forestry internet of things in forestry mainly involves the protection, preservation, cultivation of germplasm, seedlings, and afforestation and forest tending. Applying the agriculture and forestry IOT technology in forestry management can strengthen the management of forestry resources, improve the quality of afforestation, and ensure the safety of forestry production in China. 1. Protection of forest germplasm resources In the protection of forest germplasm resources, the agriculture, forestry, and internet of things can use technologies such as RFID, infrared sensors, sensors, video surveillance, wireless communications, and mobile internet to build sensor networks for protecting forests in situ and in different places. Strengthen the protection of germplasm resources of forest tree collection bases, especially precious, rare and endangered mother trees. To build a three-dimensional sensing and monitoring network for forest germplasm resource conservation facilities, enhance real-time monitoring and control of the preservation environment of the facility, and effectively preserve forest germplasm resources. 2. Forest tree seedlings cultivation and deployment In forest tree seedling breeding and deployment, sensors, video surveillance and automatic control technologies can be applied to the Agri-forestry Internet of Things to strengthen the temperature, humidity, light intensity, and soil fertility of large-scale forest seedling breeding bases. Such as the implementation of monitoring, combined with automatic sprinkler irrigation, automatic roller blinds and other operations, improve seedling cultivation of information, mechanization, automation level, to achieve intelligent management. Combining various types of electronic bills, the deployment management of forest seedlings, especially precious seedlings, will be strengthened. 3. Afforestation management and services In terms of afforestation management and services, the Agri-forestry Internet of Things can enhance the intelligent monitoring and analysis of the forestation environment and forest stand growth status through the use of sensors such as atmospheric environment, soil environment, and water environment, combined with GIS systems. And cloud computing technology, to achieve decision-making support for appropriate land, soil testing formulations, tending management, and provide related services to forest farms, forest farmers, forest companies. In addition, the Agri-forestry Internet of Things is also commonly used in forestry pest and disease detection, disaster monitoring and early warning, etc. It can effectively prevent and reduce pests and diseases by strengthening the application of a new generation of information technology such as the Internet of Things in forestry pests and diseases, disaster monitoring, early warning and forecasting, and emergency prevention and control.
