Using drones to achieve precision agricultural irrigation can help farmers use water scientifically and improve agricultural production efficiency and economic benefits.
Advantages of drone agricultural irrigation:
1.Efficient
Traditional irrigation methods require manual inspection, fertilization, and watering, which is time-consuming and labor-intensive. Drones can quickly sense soil and crop conditions, spray water and fertilizer accurately, and greatly improve work efficiency.

2.Cost savings
The drone's spraying method is precise and controllable, avoiding the problem of over-wetting the soil and cost waste, which can reduce waste and lower irrigation costs.
3.Reduce losses
Traditional spraying methods may cause a loss of some water and fertilizer, but drones can spray quickly and accurately to reduce losses.
Precision three-dimensional mapping and remote sensing control, thus achieving quantitative analysis and precise management of farmland.
Application scenarios of drone agricultural irrigation
1. Accurately measure soil moisture changes.
Drones can carry a variety of remote sensing equipment to quickly scan and accurately measure farmland. They can use sensors to accurately detect, analyze and evaluate soil moisture types and nutrients, thereby helping farmers use water scientifically, providing a scientific basis for irrigation, and conducting precise irrigation management.

2.Achieve precise control of pesticide spraying
Drones can analyze and identify pests and diseases in farmland by carrying multispectral sensors, thereby achieving precise control of pesticide spraying and avoiding excessive use of pesticides.
Using remote sensing equipment to obtain soil and crop conditions, drones can spray intelligently to achieve the purpose of optimizing sprinkler irrigation effects.
3.Realizing smart agricultural fertilization
Drones can be equipped with sensors and control systems to quickly scan and analyze crops in farmland, thereby achieving personalized fertilization of crops and avoiding waste of pesticides and over-fertilization.
4.Crop inspection
With the help of drones, farmers can easily patrol large tracts of farmland and detect problems such as pests and diseases in a timely manner.
5. Data Analysis
Drones can obtain large amounts of farmland data, conduct detailed analysis of the data, and provide precise guidance for planting management.
The principle of drone precision agriculture irrigation

The principle of precision agricultural irrigation by drones is to quickly scan and accurately measure the farmland environment and crop growth status by carrying various sensors and control systems, thereby achieving precise control of agricultural irrigation. Among them, drones can be equipped with multi-spectral sensors to analyze and identify light of different wavelengths, thereby evaluating and monitoring the growth status of crops. At the same time, drones can also be equipped with high-precision positioning systems and remote sensing control systems to achieve high-precision control of farmland.
The Prospects of Drones in Agricultural Irrigation
In terms of emergency rescue, drones can quickly reach the scene of the accident with their flexibility and rapid response capabilities, provide first-hand information, and assist rescuers in planning rescue plans. For example, drones can provide an aerial perspective at the scene of the accident, help rescue commanders better plan rescue plans, and assist in traffic diversion. In terms of traffic accident handling, drones can quickly arrive at the scene for investigation, and use shouting equipment to inform car owners to evacuate and restore road order.

With the continuous advancement of science and technology, the application prospects of drones in agricultural irrigation are becoming more and more broad. In the future, drones will be more intelligent, able to automatically sense irrigation areas, and achieve fully automated irrigation. While improving agricultural production efficiency, they can also better protect the environment and achieve sustainable development.
