Automatic weather station: Agriculture needs meteorological environment observation

Corn yield and quality are related to climate, variety, soil texture and other factors. In Heilongjiang, the temperate and cold temperate continental monsoon climate, four distinct seasons, summer rain and heat in the same season, the soil is mostly black loam, fertile soil, suitable for the growth and development of corn in one season. Among the many factors affecting the yield and quality of corn, soil water is very important, which is the main source of water required by corn in its life, especially in the vigorous growth period of corn, that is, the jointing period and the reproductive growth period, the flowering period, which is very sensitive to water requirements.

Soil drought, resulting in a large number of active oxidation substances and free radicals in the plant body, resulting in plant injury and death. Studies have shown that plants accumulate large amounts of polyphenols during times of stress such as drought, and polyphenols can reduce the oxygen content of plants and can also stop the oxidation process. In the face of drought, plants will undergo a series of changes to resist the adverse external environment.

Soil drought will affect the growth and development of grape plants and affect the quality of fruit, including the appearance and internal sugar content, organic acids, VC and so on.

The above factors affect the development of agriculture, and agriculture needs meteorological environment observation.

The automatic weather station is composed of monitoring platform, acquisition system, communication system, sensor system, power supply system, real-time monitoring system and mechanical installation system. It can simultaneously measure air temperature and humidity, wind direction, wind speed, rainfall, soil temperature, soil moisture, light intensity, atmospheric pressure and other meteorological environmental factors. Combine reality observation and LED display. With the open and friendly design concept, users can change the cooperation of elements and modules themselves, and can quickly realize the change and expansion of data acquisition and processing methods and observation elements.
