How to propagate Strelitzia reginae
Strelitzia reginae (scientific name: Strelitzia reginae), also known as bird of paradise flower, is a tropical ornamental plant loved for its unique flower shape and bright colors. Strelitzia reginae can be propagated through division, sowing and tissue culture, among which the division method is the most common and simple to operate. This article will introduce the breeding method of Strelitzia reginae in detail, and attach relevant data for reference.
1. Division propagation method
Propagation by division is the most commonly used propagation method for Strelitzia reginae and is suitable for home growers. The specific steps are as follows:
| steps | Operating Instructions | Things to note |
|---|---|---|
| 1. Select the mother plant | Choose healthy, vigorously growing adult Strelitzia reginae plants. | The mother plant needs to have 3-5 tillering buds. |
| 2. Branching time | Spring or autumn is the best time for division. | Avoid operation during high or low temperatures. |
| 3. Branching operation | Remove the mother plant from the pot and split the rhizomes with a sharp knife. | Each plant needs to retain 2-3 bud points and part of the root system. |
| 4. Transplanting and maintenance | Plant the divided seedlings into new pots, water them thoroughly and place them in a cool place. | Keep the soil moist and avoid direct sunlight. |
2. Sowing and propagation method
Propagation by sowing is suitable for large-scale seedling cultivation, but the cycle is long and may take 3-5 years from sowing to flowering. The following are key data for sowing and propagation:
| Project | parameters |
|---|---|
| seed germination temperature | 25-30℃ |
| germination time | 30-60 days |
| sowing medium | Peat soil:perlite=3:1 |
| Sowing depth | 1-2cm |
| Seedling transplanting time | When 3-4 true leaves grow |
3. Tissue culture propagation
Tissue culture is an efficient method for commercial propagation of Strelitzia reginae, but requires specialized equipment and operating techniques. The main process is as follows:
| stage | Medium formula | Culture conditions |
|---|---|---|
| First generation training | MS+6-BA 2mg/L+NAA 0.2mg/L | Temperature 25±2℃, light 12h/d |
| Proliferation culture | MS+6-BA 1mg/L+NAA 0.1mg/L | Temperature 25±2℃, light 12h/d |
| Rooting culture | 1/2MS+IBA 0.5mg/L | Temperature 25±2℃, light 12h/d |
| Seedling hardening and transplanting | Perlite:Vermiculite=1:1 | Humidity 80%, gradually decreasing |
4. Main points of post-breeding care
No matter which breeding method is used, post-breeding care is crucial. The following are key maintenance points:
| Maintenance project | Specific requirements |
|---|---|
| light | Likes plenty of scattered light, needs 50% shade in summer |
| temperature | The suitable temperature for growth is 18-27℃, not lower than 10℃ in winter |
| Moisture | Keep the soil moist but not waterlogged, and reduce watering in winter |
| fertilize | Apply a diluted balanced fertilizer every 2 weeks during the growing season |
| pests and diseases | Pay attention to preventing and controlling spider mites and root rot |
5. Frequently Asked Questions
1.Why does the plant grow slowly after division?
It may be that the root system was damaged too much when dividing the plants, or the environment was not adapted to it after transplanting. It is recommended to retain enough roots when dividing the plants, and place them in a cool and ventilated place to slow down the seedlings for 2-3 weeks after transplanting.
2.Why is the germination rate low during sowing propagation?
The freshness of Strelitzia reginae seeds has a great influence on the germination rate. It is recommended to sow seeds immediately after purchase, or store them in a refrigerator at 4°C for no more than 3 months. Soak in warm water for 24 hours before sowing to promote germination.
3.Why is the survival rate of transplanted tissue culture seedlings low?
Tissue culture seedlings need to undergo a thorough seedling hardening process. Before transplanting, the seedlings should be hardened for 3-5 days by opening bottles. After transplanting, maintain a high humidity environment and gradually reduce it to normal conditions.
Through the above detailed propagation methods and maintenance points, I believe you can successfully propagate healthy Strelitzia reginae plants. Choose the appropriate breeding method according to different needs and maintain it patiently, and you can enjoy this beautiful "bird of paradise" flower.
