Because meteorological disasters have caused huge losses in agricultural production, the use of agricultural environmental monitoring stations to regularly monitor the agricultural environment is a very important issue for modern agricultural production. However, because the work environment for agricultural environmental monitoring stations is mostly in the wild, it is not only necessary to ensure that the environmental data it detects is representative, but also to reduce the impact of harsh environments on it. Therefore, the choice of sites for agricultural environmental monitoring stations is very high. Important.
1. Pay attention to the effects of terrain and ground faults. This is especially important for wind measurements because terrain fluctuations and the presence of obstacles can distort the wind direction and wind speed. To avoid this effect, the distance between the edge of the observation field and the surrounding obstacles should be more than ten times the height of the obstacle. The weather station is best to be in a flat, airy place.
2. Pay attention to the environmental conditions around the site of the agricultural environmental monitoring station. The results of the data detected by the agricultural environmental monitoring station must be representative and must be able to reflect the characteristics of the environmental elements in the larger area. Therefore, special attention must be paid to the environmental conditions around the site of the agricultural environmental monitoring station. , Choose a representative plot for installation.
3. Observation sites should be far away from pollution sources Pollution sources include not only common pollutants such as chemical pollution, but also light pollution, electromagnetic wave pollution, etc. The observation site of the Agricultural Environment Monitoring Station should be far away from these sources of pollution, mainly because electromagnetic wave pollution will affect the correct measurement of temperature and other factors; chemical pollution will affect the moisture measurement results of the humidity sensitive capacitors; shadows and reflective objects of obstacles will affect the amount of solar radiation and Measurement of sunshine hours. However, there are exceptions. For example, short shrubs are good for measuring precipitation. Therefore, the installation site should be adjusted according to observation requirements.
In addition, the site for the installation of agricultural environmental monitoring stations is generally selected to be flattened to facilitate observation operations. It is necessary to pay attention to maintaining the natural state of the observation site. At the same time, the layout of equipment and facilities in the site must be kept in check to ensure the monitoring work. All can go smoothly.
