Plug Seedling Machine | Nursery Seedling Machine

The plug seedling machine is a specialized agricultural solution designed for the efficient cultivation of fruit, vegetable, and flower seedlings. By integrating precision seeding technology, it achieves a single-seed accuracy rate of 95–98%, significantly improving germination consistency and reducing seed waste.

Compared with manual work, one machine can replace 6–10 workers and increase efficiency by 3–5 times, processing large quantities of plug trays per hour.

Widely used in vegetable farms, flower nurseries, agricultural cooperatives, and commercial seedling bases, the plug tray seeder meets the growing demand for high-efficiency and uniform seedling cultivation.

As a professional agricultural machinery manufacturer, we also provide complementary equipment, such as vegetable and rice transplanters , helping farmers move from seeding to transplanting through a fully mechanized process.

Application of the plug seedling machine

The plug seedling machine is suitable for a wide range of seeds, especially for vegetables and flowers requiring precision sowing. It can handle crops such as:

• Leafy vegetables: lettuce, spinach, arugula, bok choy, cabbage
• Root vegetables: carrot, beet, radish, turnip
• Cruciferous crops: broccoli, kale, mustard
• Fruit vegetables: tomato, cucumber, pumpkin, okra, sweet corn
• Herbs and others: cilantro, celery, scallions, amaranth

Its versatility makes it ideal for diversified planting operations and commercial nursery production.

Working principle of the nursery seedling machine

The plug seedling machine operates using an advanced vacuum suction and positive pressure release system, ensuring precise “one seed per hole” sowing:

1. The air compressor generates negative pressure through a vacuum device.
2. Seeds are absorbed from the seed box by suction.
3. When the sensor detects the tray cells, the metering system aligns with each hole.
4. The system switches to positive pressure, accurately releasing seeds into each plug cell.

This process guarantees uniform seeding, minimizes seed waste, and ensures consistent seedling growth, which is critical for commercial-scale nursery operations.

Different models of vegetable nursery seedling machine

To meet different production needs and budgets, we provide multiple types of plug seedling machines, from semi-automatic to fully automatic and intelligent models. Each model is designed for specific applications, ensuring flexibility and efficiency for various users.

Type 78 Manual seedling machine (semi-automatic)

The Type 78 is a compact and economical semi-automatic tray seeder, suitable for small farms and startup nurseries. It mainly performs hole punching and seeding, while tray loading and unloading are done manually.

Advantages of the manual tray seeder machine

• Small size, lightweight, easy to move.
• Simple structure with stable performance.
• Integrated hole punching and seeding in one step.
• Adjustable suction nozzles for seeds (0.3–12mm).
• Achieves “one hole, one seed” with uniform depth.
• Reduces labor intensity with easy operation.

Type 80 Automatic seeding machine

The Type 80 is a fully automatic nursery seeding machine designed for medium to large-scale production. It can complete the entire process automatically.

Main functions:

• Substrate filling → hole pressing → seeding → soil covering
• Optional watering system

Advantage of the automatic vegetable seeder

• One-button operation with control system.
• High efficiency with continuous operation.
• Complete seeding process in one run.
• Modular structure (two main sections).

Components of the automatic nursery seed sowing machine

This 80 automatic nursery seed sowing machine has two parts. One part includes the soil bin, brushing, digging, and sowing. Another part has a second soil covering and brushing. Also, you can choose the watering at the end of the machine.

Advantages of using a plug seedling machine

• Save labor and cost: reduces manual work and energy consumption, making large-scale nursery management easier and more efficient.
• High-quality substrate: uses light materials like peat, vermiculite, and perlite, which offer good air permeability, water retention, and low disease risk—ideal for healthy seedling growth and smooth machine operation.
• Higher germination rate: ensures strong and uniform seedlings while reducing seed waste.
• Higher planting density: produces more seedlings in limited space, lowering greenhouse investment and operating costs.
• Uniform and precise seeding: mechanized operation ensures consistent filling, seeding depth, and covering, resulting in even germination and standardized seedlings.
• Easy sanitation: the entire production process can be easily cleaned and disinfected, helping prevent diseases and improve seedling quality.

Principles for choosing a plug seedling machine

• Focus on seedling quality and safety: the machine and substrate should be free of pathogens, pests, and harmful substances to avoid polluting the soil and food chain. Fermented substrates are recommended to achieve sterilization and safer production.
• Ensure suitable growing conditions: the cultivation substrate should provide good air permeability, water retention, and support root development, creating a better environment than traditional soil.
• Use proper substrate combinations: choose a scientific mix of organic and inorganic materials to balance moisture, airflow, and overall seedling health.
• Consider cost and local resources: select locally available, high-quality, and low-cost substrates to reduce production expenses while maintaining performance.
