High-Accuracy Onion Planting Solution for Modern Agriculture
- Introduction: The Challenge of Onion Planting
Onion cultivation is one of the most demanding segments in vegetable production. Unlike large-seed crops such as corn or beans, onion seeds are extremely small, lightweight, and irregular in shape. This makes uniform planting, accurate spacing, and stable emergence difficult to achieve using traditional mechanical seeders or manual sowing methods.
In many regions around the world, onion growers still face common problems such as:
• Uneven seed distribution
• High seed wastage
• Inconsistent plant spacing
• Poor germination uniformity
• Excessive labor costs
To address these challenges, vacuum precision onion seeders, also known as air suction onion seeders, have become an essential solution for modern, large-scale, and precision-oriented agriculture.
Our Vacuum Precision Onion Seeder is designed and manufactured specifically for high-efficiency onion planting, combining advanced air suction technology, durable mechanical structure, and flexible configuration options to meet the needs of growers worldwide.

- What Is a Vacuum Precision Onion Seeder?
A vacuum precision onion seeder is an agricultural planting machine that uses negative air pressure (vacuum suction) to pick up, transport, and release individual onion seeds at precisely controlled intervals.
Unlike conventional seeders that rely on gravity or mechanical agitation, a vacuum seeder ensures:
• One seed per hole
• Consistent spacing
• Uniform planting depth
• High planting accuracy
This technology is particularly suitable for:
• Onion seeds
• Leek seeds
• Chive seeds
• Small vegetable seeds
⸻
- Working Principle of the Vacuum Onion Seeder
The working principle of the vacuum precision onion seeder can be summarized in five key steps:
3.1 Vacuum Generation
A high-performance fan or turbine creates negative pressure inside the seeding system. This vacuum is distributed evenly to each seeding unit.
3.2 Seed Pickup
As the seed plate rotates, vacuum holes on the plate pick up onion seeds from the seed hopper. The vacuum force ensures that only one seed adheres to each hole.
3.3 Excess Seed Removal
If more than one seed attaches to a hole, an adjustable seed scraper or air release mechanism removes the excess seeds, guaranteeing single-seed precision.
3.4 Seed Release
When the seed plate rotates to the release point, the vacuum is cut off, allowing the seed to fall freely into the seed tube.
3.5 Precise Placement
The seed is guided into the furrow at a consistent depth and spacing, followed by soil covering and compaction to ensure optimal seed-to-soil contact.
