In horticulture and agriculture, seedling trays are important tools for improving the seed germination rate and seedling survival rate. Mastering the correct seedling tray planting skills can significantly improve the health and survival rate of seedlings. This article will introduce the key skills and secrets of seedling tray planting to help you achieve the best results in the planting process.
1. Choose the Suitable Seedling Tray
Choosing the appropriate seedling tray is the first step to successful planting. The material and specification of the seedling tray directly affect the seed germination and seedling growth.
Material selection: Plastic seedling trays are highly durable and suitable for multiple uses; foam seedling trays are lightweight and have good heat preservation; paper seedling trays are environmentally friendly and have good air permeability.
Specification selection: Choose the appropriate aperture according to the size of the seeds and planting requirements. Small-aperture seedling trays are suitable for small seeds, and large-aperture seedling trays are suitable for large seeds.
2. Prepare High-quality Substrate
High-quality substrate is the key to ensuring the smooth germination of seeds and the healthy growth of seedlings.
Substrate selection: Commonly used substrates include peat, coconut coir, perlite, etc. When mixing the substrate, ensure it has good air permeability, drainage and water retention.
Substrate disinfection: Disinfect the substrate before use to prevent infection by germs and pests. It can be processed by steam disinfection or high-temperature baking.
3. Conduct Seed Treatment
Conducting seed treatment before sowing can significantly improve the germination rate and seedling quality.
Seed soaking: Soak the seeds in warm water for several hours to overnight to soften the seed coat and promote the absorption of water and germination of the seeds.
Germination promotion treatment: Some seeds treated in a low-temperature or high-temperature environment for a period of time can break dormancy and improve the germination rate.
4. Correct Sowing Method
The correct sowing method is the basis for ensuring the germination of seeds and the healthy growth of seedlings.
Fill the substrate: Fill the substrate evenly into the seedling tray and slightly compact it, but maintain good air permeability.
Even sowing: According to the size of the seeds, evenly sprinkle the seeds on the surface of the substrate or sow by holes. Small seeds can be directly broadcast, and large seeds can be sown by holes and covered with an appropriate amount of substrate.
Watering: Gently spray water mist after sowing to keep the substrate moist but not too wet to avoid seed rot.
5. Management during the Germination Period
During the seed germination period, it is necessary to maintain suitable environmental conditions to promote the smooth germination of seeds.
Moisture retention: Keep the substrate moist but not too wet. Fine mist spraying can be performed using a sprayer.
Temperature control: Most seeds germinate best at a temperature of 20-25°C. A seedling tray cover can be used to maintain the temperature or the seedling tray can be placed in a warm environment.
Light: Some seeds require light during the germination period. Manage according to the needs of the seeds. Seeds that require light can be placed in a sunny place or supplemented with plant growth lights.
6. Management during the Seedling Period
After the seeds germinate, enter the management of the seedling period to ensure the healthy growth of the seedlings.
Sufficient light: Seedlings require sufficient light, at least 12-16 hours a day. Use plant growth lights to supplement the light, especially in seasons with insufficient light.
Appropriate watering: Keep the substrate moist but not too wet to avoid root rot caused by water accumulation. Gradually reduce the watering frequency to promote root growth.
Fertilization management: After the seedlings grow two true leaves, appropriate fertilization can be started. Select diluted liquid fertilizers to avoid burning the seedlings due to excessive fertilizer concentration.
7. Transplanting Preparation
When the seedlings grow to a certain stage, transplantation is required to ensure the seedlings continue to grow healthily in the new environment.
Transplanting time: Transplantation is generally carried out when the seedlings grow 3-4 true leaves.
Preparation before transplantation: Gradually reduce the watering a few days before transplantation to enhance the adaptability of the seedlings. Choose a cloudy day or evening for transplantation on the day of transplantation to reduce the damage of direct sunlight to the seedlings.
8. Conclusion
The skills and secrets of using seedling trays for planting can significantly improve the seed germination rate and seedling survival rate. By choosing the appropriate seedling trays, preparing high-quality substrates, conducting seed treatment, mastering the correct sowing methods and scientific management, you can achieve the best results in the planting process. I hope the methods provided in this article can help you achieve efficient seedling raising and enjoy the joy of a bountiful harvest.
