What is intelligent spraying in agriculture?

Smart spraying in agriculture refers to a modern agricultural technology that utilizes sensing, positioning, control, and information technology to achieve precise and automated management of pesticide or fertilizer spraying. Its core goal is to spray at the right time, place, and dosage to improve efficiency, reduce costs, and minimize pollution.

1、 The core principle of intelligent spraying

Intelligent spraying systems typically consist of the following parts:

1. Sensing system:

Real time detection of crop growth status, pest and disease distribution, weed location, etc. using cameras, LiDAR, ultrasonic or multispectral sensors.

2. Positioning and Navigation System:

Using GPS/Beidou positioning system to achieve precise path control of spraying equipment, ensuring no missed or repeated spraying.

3. Control system:

Automatically adjust the nozzle switch, spray volume and spray pressure according to the test data to achieve "on-demand spraying".

4. Data management platform:

Upload spraying data to the cloud or agricultural management system for job recording, pesticide usage statistics, pest and disease analysis, etc.

2、 The main types of intelligent spraying

1. Unmanned aerial vehicle intelligent spraying

By equipping crop protection drones with intelligent spraying systems, precise spraying can be achieved based on maps or AI recognition.

2. Self propelled/crawler spray intelligent spraying

Suitable for fields and orchards, equipped with radar and AI recognition systems that can identify tree crowns and crop row spacing for targeted spraying.

3. Orchard intelligent spraying robot

A small robot walks in the orchard, determines the spraying area through visual recognition, and achieves automatic obstacle avoidance and quantitative spraying.

3、 The advantages of intelligent spraying

Save pesticides: Spray as needed, which can save 30% to 70% of the amount of medication used.

Environmental safety: Reduce pesticide residues and soil and water pollution.

Improve efficiency: Automated operations greatly reduce manual labor intensity.

Precise prevention and control: Real time identification of the distribution of pests and diseases, and more targeted spraying.

Traceability management: Homework data can be saved for traceability and supervision.

4、 Application examples

Orchard: The nozzle automatically adjusts the spraying amount according to the size of the tree crown.

Datian: AI identifies weeds and only sprays herbicides on them.

Greenhouse: Automatically adjust the spraying cycle based on humidity and disease risk.
