1. Basic conditions for seed germination
Seed germination needs to meet the following basic conditions:
| Conditions | Description |
|---|---|
| Moisture | Seeds need to absorb enough moisture to initiate the germination process |
| temperature | Different seeds have different temperature requirements, generally between 15-30℃ |
| oxygen | Seed respiration requires adequate oxygen |
| light | Some seeds need light, others need darkness |
2. Steps of seed germination
1.Choose high quality seeds: Buy fresh, plump seeds for a higher germination rate.
2.seed treatment:
| Treatment method | Applicable seeds | Operation mode |
|---|---|---|
| Soak in warm water | hard shell seeds | Soak in warm water at 40-50℃ for 12-24 hours |
| Cold storage | Seeds that need vernalization | Store in the refrigerator for 1-3 months |
| scratch treatment | thick shelled seeds | Lightly rub the seed coat with sandpaper |
3.Preparing the seedling substrate: Use a loose, breathable, water-retaining substrate, such as vermiculite, perlite or professional nursery soil.
4.Sowing method:
| sowing method | Applicable situations | Operational points |
|---|---|---|
| spread | small seeds | Spread evenly on the surface of the substrate without covering it with soil |
| on demand | large seeds | Sow seeds at a certain distance and cover with soil 1-2cm |
| drill | medium seeds | Dig shallow trenches for sowing and cover with thin soil |
5.Germination management:
- Keep the substrate moist but not waterlogged
- Provide suitable temperature (can be assisted by heating pad)
- Provide light or shade according to seed needs
3. Common problems and solutions
| question | Possible reasons | solution |
|---|---|---|
| Does not germinate | Old seeds, uncomfortable temperature, and insufficient water | Replace with fresh seeds and adjust temperature and humidity |
| Die after germination | Excess moisture, disease, sudden temperature changes | Control watering to keep the environment stable |
| Germination is uneven | Different sowing depths and uneven substrate | Uniform seeding depth and use uniform substrate |
4. Popular seed germination techniques
According to recent Internet hot spots, the following seed germination methods have received widespread attention:
| Seed type | special request | germination time |
|---|---|---|
| avocado | Requires hydroponics, retaining the skin of the core | 2-6 weeks |
| dragon fruit | The pulp needs to be filtered and sown shallowly. | 5-10 days |
| lavender | Need to be refrigerated, Xiguang | 14-28 days |
| strawberry | Requires low temperature for germination and keeping moist | 10-20 days |
5. Management of seeds after germination
1.Lighting management: The seedling stage needs sufficient but soft scattered light and avoid direct strong light.
2.moisture management: Keep the substrate moist and it is safer to use spray watering.
3.temperature management: Maintain stable temperature and avoid excessive temperature difference between day and night.
4.Fertilizer management: After the seedlings grow 2-4 true leaves, diluted liquid fertilizer can be applied.
Conclusion
Seed germination is a process that requires patience and care. By understanding the characteristics of different seeds, providing suitable environmental conditions, and mastering the correct handling methods, you can greatly increase the success rate of seed germination. Hopefully the structured data and practical tips provided in this article will help you successfully grow healthy seedlings.
