Ultraviolet radiation, as an important component of solar radiation, directly affects meteorological processes, crop growth, and pest control through its intensity changes.254Ultraviolet radiation illuminance meter with high-precision wavelength selectivity（245nm-265nm）Real time monitoring capability has become a key tool for meteorological observation stations, agricultural research bases, and smart farms. The core value of agricultural meteorological services is analyzed from three dimensions: meteorological environment monitoring, crop physiological regulation, and pest control.

1、 Meteorological field: Building a UV radiation database to support climate modeling and disaster warning

1. Monitoring of Atmospheric Ozone Layer and Validation of Climate Models

UV radiation illuminance meter can quantitatively analyze254nmThe intensity of ultraviolet radiation in this band is highly correlated with the absorption characteristics of the ozone layer. Through long-term observation data, meteorological departments can invert the vertical distribution of atmospheric ozone concentration and verify the accuracy of predicting ozone layer depletion in climate models. For example, at the Qinghai Tibet Plateau Ozone Observatory,254nmThe collaborative analysis of illuminance meters and satellite remote sensing data reveals the phenomenon of enhanced ultraviolet radiation during the spring ozone trough, providing key parameters for the implementation of the Global Framework Convention on Climate Change.

2. UV index（UVI）Forecasting and Public Health Services

Combining meteorological factors such as solar altitude angle and cloud cover, the data from the illuminance meter can be calculated in real-timeUVIValue, and through meteorologyAPPIssuing sun protection warnings to the public.2023In the summer of, the Jiangsu Provincial Meteorological Bureau utilized a distributed ultraviolet monitoring network toUVIImproved forecast accuracy to92%, effectively reducing the incidence rate of skin cancer, cataract and other UV related diseases. In high-altitude areas, instruments can also monitor the ultraviolet intensity during periods of high incidence of snow blindness, providing protective guidance for outdoor workers.

3. Traceability of photochemical smog pollution

Ultraviolet radiation is a key driving factor in the formation of photochemical smog. Illuminometer andVOCsThe combination of volatile organic compound (VOC) monitoring instruments can quantitatively evaluate the contribution rate of ultraviolet radiation to ozone generation. In the Beijing Tianjin Hebei region, by constructing“ultraviolet-ozone”Dynamic model, meteorological department successfully identified the surrounding area of the industrial park3The hotspots of photochemical pollution within a kilometer range provide scientific basis for precise pollution control.

2、 Agricultural production: optimizing light environment management to improve crop yield and quality

1. Facility agriculture light regulation and variety breeding

In greenhouse cultivation, the ultraviolet radiation illuminance meter can monitor the output stability of the supplementary light in real time, ensuring that crops obtain suitableUV-A/UV-Bproportion. For example, during the tomato seedling stage, by controlling254nmThe intensity of ultraviolet radiation is15-20μW/cm²Within the range, it can significantly improve the stress resistance of seedlings and increase the survival rate of transplantation18%In flower production, the UV gradient processing guided by instrument data increases the deposition of pigment in Phalaenopsis petals30%The viewing value has significantly increased.

2. Green prevention and control of pests and diseases

Ultraviolet radiation has a significant impact on insect behavior. The linkage between the illuminance meter and the insect detection alarm light can be established“ultraviolet-Pest activity”Correlation model. During the migration period of rice planthoppers, monitoring changes in nighttime ultraviolet intensity can predict pest aggregation areas, guide drones to accurately spray biological pesticides, and reduce the use of chemical pesticides40%The above. In addition,254nmUltraviolet rays can inhibit the germination of spores of plant pathogens. Instrument data can optimize the operation period of ultraviolet disinfection equipment and reduce the incidence rate of cucumber downy mildew in greenhouse.

3. Improvement of Agricultural Product Quality and Storage and Transportation Protection

Ultraviolet radiation illuminance meter plays a key role in post harvest processing of fruits and vegetables. Before storing apples, use254nmUltraviolet irradiation30Seconds can activate the endogenous antioxidant system of the fruit, maintaining the initial values of hardness and soluble solids content, respectively85%and90%Extended storage period20Oh my god. In tea processing, the instrument monitors the ultraviolet dose to control the withering process, which increases the content of catechins in green tea12%The bitter taste of the tea soup is significantly reduced.

3、 Technology Fusion: Smart Agriculture Practice Driven by IoT and Big Data

Modern ultraviolet radiation illuminance meters have achieved deep integration with IoT platforms. At the Smart Farm in Yancheng, Jiangsu, a distributed sensor network collects real-time data on ultraviolet radiation, temperature and humidity, and light intensityAIalgorithm generation“light-Wen-water”Collaborative control plan.2024The pilot program showed that the system increased the protein content of wheat2.3Percentage point increase in water-saving efficiency15%At the Hainan Tropical Fruit Base, instruments are combined with blockchain technology to establish a UV treatment traceability system. Consumers can view the post harvest UV disinfection records of mangoes by scanning the code, and the brand premium rate is up to25%.

Conclusion

From meteorological environment monitoring to agricultural production optimization, ultraviolet radiation illuminance meters are promoting the development of agricultural meteorological services towards precision and scientific direction through accurate measurement, intelligent analysis, and scenario based applications. with5G+AIWith the popularization of technology, this instrument will achieve cross regional data sharing and automatic decision-making in the future, providing stronger technical support for addressing climate change and ensuring food security. As experts from the Chinese Academy of Agricultural Sciences have stated:“Ultraviolet radiation is given to agriculture by the sun‘Invisible fertilizer’And the illuminance meter is the key to unlocking this gift.”
