Solar greenhouses have been widely adopted because of their good thermal insulation performance and can be used without warming to plant winter vegetables. They are more energy-efficient and more efficient than large-scale multi-span greenhouses and smart greenhouses. During the application of solar greenhouses, we also found that meteorological conditions have a very close management relationship with their production management. Whether it is low temperature, low temperature, strong cooling, strong wind or heavy snow, the weather has a serious impact on the safe and efficient production of greenhouses. With the development of technologies in meteorological automatic monitoring, numerical weather prediction, communications, and information services, the research and application of meteorological monitoring and early warning technologies in solar greenhouses have made gratifying progress. Small agricultural meteorological stations have been widely used in the construction and development of facility agriculture. The application opens.
In recent years, with the construction of a regional meteorological observation station network, small-scale agricultural meteorological stations of higher density have been established in various places so that meteorological changes in various types of greenhouses can be grasped in real time in various regions of the city, but changes in the solar greenhouses As well as the lack of understanding of the quantitative relationship between indoor and outdoor, it is necessary to build a real-time automatic meteorological monitoring station network for the status of greenhouses, so as to achieve real-time monitoring and accurate forecasting and warning services for different types of greenhouse meteorological elements in different regions. In districts and counties where sunlight greenhouses are relatively concentrated, we choose to plant typical greenhouses with representative crops, install small-scale agricultural meteorological stations, and simultaneously carry out corresponding biological observations to form a citywide solar greenhouse weather monitoring network to monitor weather conditions in greenhouses in real time. Its impact on crops.
At present, a subsystem of agricultural weather monitoring for sunlight greenhouses consisting of 16 multi-element small agricultural meteorological stations has been built, including 8 inside and outside the greenhouse, and the observed meteorological elements include temperature, humidity, ground temperature, total radiation, and effective photosynthetic. Radiation, carbon dioxide, etc. The equipment uses GPRS wireless transmission. The main objective of small-scale agricultural meteorological stations is to monitor the environmental factors of remote unattended locations and to achieve data collection, remote transmission, storage management and distribution. Divided from the structure, the system consists of three parts: terminal data acquisition and transmission module, server-side data receiving and storage module, Web-based data management module.
The small-scale agricultural meteorological station can monitor the greenhouse microclimate in real time and publish the data collection and service information, so that the greenhouse weather monitoring and disaster warning can basically meet the needs of the greenhouse climate monitoring and early-warning. It is a useful assistant for the development of modern equipment agriculture. Not only has it promoted the growth of crops and ensured yield and quality, but it has further promoted the construction and development of agriculture and raised the income of farmers' economy.
