Detailed explanation of seedling raising technology in seedling trays

The technology of raising seedlings in trays has gained popularity due to its efficiency and effectiveness in modern agricultural practices. According to informative resources on Google, these techniques not only optimize germination rates but also enhance management capabilities for crops at early stages. This article will provide a comprehensive overview of seedling raising technology using seedling trays, covering their selection, production, usage, and management skills.

Selection and Production of Seedling Trays

1. Material Selection

The most common materials for making seedling trays include plastic, glass, and ceramics. Plastic seedling trays are lightweight and resistant to corrosion, making them cost-effective. Glass trays, on the other hand, offer high transparency, which allows easy monitoring of plant growth. Ceramic trays are beneficial for environments with lower temperatures due to their insulation properties. It is essential to evaluate the actual requirements and environmental conditions when selecting a seedling tray.

2. Production

(1) Plastic Seedling Tray Production Method:

a. Gather the required materials: polyethylene granules, water, mixer, heat gun, and mold.

b. Combine polyethylene granules with a specific amount of water in a blender until mixed well, then transfer to the mold.

c. Heat the mixture at high temperatures, cool, and demold to retrieve the plastic seedling tray.

(2) Glass Seedling Tray Production:

a. Required materials include quartz sand, soda ash, and a high-temperature furnace.

b. These components are combined in a high-temperature furnace until molten; they are then cast into molds.

e. Manual methods can be applied to produce ceramic seedling trays.

How to Use the Seedling Tray

1. Cleaning and Disinfection:

Prior to utilizing the seedling tray, cleaning and disinfection are vital. Warm water with a mild detergent is typically effective. Plastic trays can utilize diluted bleach, while glass and ceramics can be disinfected using vinegar or alcohol.

2. Filling with Soil and Seeds:

Fill the tray with appropriate soil, ensuring it remains moist yet not overly saturated. Position seeds properly with adequate spacing, then mist the surface lightly.

3. Light and Temperature Control:

Plants require varying light and temperature levels to flourish. Sufficient sunlight is critical for most species while temperature should stay between 15-28°C. Use shade nets or heating covers to assist in managing these factors.

4. Ventilation and Humidity Control:

Proper ventilation is essential to reduce disease and promote air circulation. Balancing humidity through regular ventilation or the use of humidifiers helps maintain optimal growth conditions and prevents water loss.

Management Skills of Seedling Tray

1. Regular Observation and Adjustment:

Continuously monitoring plant growth—looking at leaf color and stem thickness—can help identify abnormalities early. Maintaining awareness of soil moisture and nutrients is critical for optimal growing conditions.

2. Timely Weeding and Pruning:

Regularly remove weeds and unhealthy plants to maintain a clean environment within the seedling tray. Pruning larger or excessive branches promotes healthier growth and encourages branching.
