What is the use of agrometeorological data? Why collect?

Install a small weather station in the farmland to monitor the farmland microclimate in real time: ambient temperature and humidity, wind speed and direction, atmospheric pressure, precipitation, light radiation, light duration...

Why do we collect these weather data? Answer: To provide data support for guiding and regulating agricultural production activities. Meteorological data is a very useful research and analysis data, which can not only help scholars research, but also guide production.

Take spraying pesticides as an example, good meteorological conditions are conducive to the effect of pesticides.

temperature

High temperature, crop metabolism is strong, stomata open, if the use of pesticides at this time, it is easy to be absorbed by crops, so spraying pesticides should avoid high temperature weather. It is understood that the appropriate temperature for spraying pesticides is 20~30 ° C.

humidness

The use of pesticides in high humidity environments will reduce the effectiveness of pesticides, but for powdered pesticides, you need to spray under certain humidity conditions. Because the powder pesticide can adhere to the leaf surface of the crop, the efficacy plays a good role. For pesticides, wet soil can absorb pesticides well and improve the control effect.

precipitation

Rain will wash away the spray on the leaf surface, affecting the effect. So the spraying should be carried out in non-rainy weather.

illumination

Some pesticides are unstable to light and are easy to decompose under light irradiation. Under strong light irradiation, the photosynthesis of crops is strong, the stomata open, and it is easy to be absorbed by crops. And the transpiration effect is strong, causing the drug to rise with the airflow into the atmosphere.

The wind

High winds will accelerate the play and decomposition of the drug, but also cause drift drug damage. Therefore, pesticide spraying should be adjusted according to the size of the wind and the direction of the wind.
