Abstract:

The Nanfan breeding base is the "gas pedal" of China's agricultural breeding, and its strategic position is very important. In order to improve the efficiency of agricultural data collection at the Nanfan breeding base, strengthen the capacity of farmland management and meet the needs of large-scale crop breeding, there is an urgent need to build an intelligent management platform for bases based on the IoT. Taking the Potianyang base in Sanya City, Hainan Province as an object, an IoT intelligent management platform for the Nanfan breeding bases has been developed. The platform deploys sensors, video monitoring, intelligent irrigation and other equipment, and develops five functional modules, such as crop weather and soil environment sensing, video monitoring, pests monitoring. Real-time monitoring of the field's weather, soil, pests, spores and other environmental information, as well as crop growth conditions can achieve intelligent and precise irrigation. The real-time sensing and intelligent warning function of the platform can realize remote monitoring and regulation of the breeding environment, providing breeders with intelligent decision-making. By intelligently obtaining crop phenotypic information, the platform also provides breeders with a large amount of experimental materials, greatly improving the efficiency and accuracy of breeding work and providing technical support for large-scale field crop breeding. In the future, relying on modern technologies such as artificial intelligence, robots and drones, the intelligent acquisition of crop phenotypic data will replace manual phenotypic measurements, the intelligent management of crop plus generation breeding will replace manual management, and the intelligent evaluation and screening of excellent varieties will replace experienced breeders, which will realize the integration of the sky and land of the Nanfan breeding bases and the intelligent digitalization of large-scale field breeding.

Key words: Nanfan breeding base, agricultural IoT, intelligent management platform, information perception, intelligent warning
