[Abstract]:The 21st century is an era of information leaps and bounds. With the rapid development of information technology, the application of information technology in agriculture has also been developed to a certain extent. Precision agriculture is a kind of development potential technology which combines information technology. Although the application of information technology in the field of agriculture is increasing, the traditional agricultural production mode is still the main way of agricultural production in our country. Compared with precision agriculture, the traditional agricultural production mode has low overall productivity, huge waste of resources and serious environmental pollution. Under the severe situation of food security and resource reduction, the defects of traditional agricultural production mode are gradually becoming more and more serious. Agricultural informatization and agricultural modernization, as the "new four modernizations", have become the mainstream trend in the current agricultural field, so the agricultural application of information technology has promoted the implementation of precision agriculture. It is of great realistic and profound historical significance to realize the precision and high efficiency of agricultural production. This paper is based on the national "863" project "Research and Application of Maize Precision Operation system" and Jilin Province World Bank loan project "Research and Application of Facility vegetable Safety production Technology based on Internet of things". An intelligent soil crop dynamic information system based on WEBGIS in Nong'an County of Jilin Province is developed. The main contents are as follows: (1) A real-time temperature and humidity sensing system is constructed by using wireless sensor technology. To achieve the real-time soil temperature and humidity information acquisition; Using the network technology, the information collected by the sensor is sent to the server for storage and processing, and the short message cat module is used to realize the function of real-time and fast feedback to the user from the conclusion of the user consulting in the system. It reduces the process of user memory and has great significance for guiding user production accurately. (2) the research and application of spatial clustering algorithm are carried out, and the spatial clustering algorithm based on DBSCAN is designed and implemented, which can be used to evaluate soil fertility and provide the basis for macro decision and precision fertilization of agricultural production managers. (3) using WebGIS and artificial intelligence technology, the intelligent system of soil-crop dynamic information is developed and realized by integrating the data acquisition system based on wireless sensor and the evaluation method of soil fertility based on spatial clustering. The system includes five functions: information query, dynamic monitoring, fertility evaluation, intelligent decision making and result output. Through the combination of wireless sensor, data mining technology, WebGIS technology and artificial intelligence technology, the research and development of soil crop dynamic information intelligent system can provide real-time information acquisition, fertility evaluation and so on for agricultural production management department. Accurate decision-making basis and can provide consultation services such as maize yield prediction, precision fertilization, disease and pest diagnosis and treatment for farmers.
