0 min readIntroduction
Anthurium, belonging to the Araceae family, is a commercially important tropical flower crop globally, and increasingly so in India. Known for its vibrant spathes (modified leaves) and spadix (flower spike), Anthurium cutflowers are prized for their aesthetic appeal and long vase life. India’s production is currently lower than other major exporters like Colombia and Thailand, presenting a significant opportunity for growth. The increasing demand for exotic flowers necessitates understanding and implementing optimal cultivation practices to maximize profitability and quality. This answer will detail the key aspects of commercial Anthurium cultivation.
Commercial Cultivation Practices of Anthurium
1. Microclimate Management
Anthurium thrives in warm, humid, and shaded environments. Direct sunlight can cause leaf burn. Key microclimate parameters include:
- Temperature: 20-30°C (68-86°F) is optimal. Frost damage can occur below 10°C.
- Humidity: 80-90% relative humidity is crucial, especially during flowering. Misting systems, fogging, and poly tunnels are commonly employed.
- Light: 20-30% shade is required. Shade cloth or natural shade (under taller trees) can be used.
- Air Circulation: Adequate ventilation prevents fungal diseases.
2. Propagation and Planting
Anthurium propagation is primarily through vegetative methods:
- Tip/Node Cuttings: The most common method. Cuttings are treated with rooting hormones (e.g., IBA) and placed in a sterile rooting medium like sphagnum moss or perlite.
- Tissue Culture: Provides disease-free, genetically uniform plants, but requires specialized equipment and expertise.
- Planting: Well-drained, aerated potting mix is essential. Coco coir, perlite, and vermiculite are commonly used. Containers should be appropriately sized to allow for root development.
3. Harvesting and Post-Harvest Handling
Harvesting is critical for maintaining flower quality.
- Stage of Harvest: Anthurium cutflowers are harvested when the spathe is fully open and the spadix is receptive to pollen.
- Harvesting Time: Early morning is best to minimize water loss.
- Post-Harvest Treatment: Immediately after harvest, flowers should be placed in clean water with a floral preservative solution (containing sugar, acidifier, and biocide) to extend vase life.
- Storage: Storage at 2-4°C (35-39°F) with high humidity (95-100%) is recommended.
4. Yield Considerations
Yield is influenced by several factors:
- Variety: 'Red Robin', 'Hawaii', and 'Minerva' are popular cultivars.
- Fertilization: Balanced fertilization is essential, with a focus on potassium and phosphorus.
- Pest and Disease Management: Thrips, aphids, and fungal diseases (e.g., Anthuriam blight) are common. Integrated Pest Management (IPM) strategies are recommended.
- Average Yield: A well-managed Anthurium farm can produce 100-150 cutflowers per plant per year.
| Parameter | Requirement |
|---|---|
| Temperature | 20-30°C |
| Humidity | 80-90% |
| Light | 20-30% Shade |
| Propagation Method | Tip/Node Cuttings, Tissue Culture |
| Harvest Stage | Fully open spathe, receptive spadix |
The National Horticulture Board (NHB) under the Ministry of Agriculture & Farmers Welfare provides support for horticulture crops, including Anthurium, through various schemes. The MIDH (Mission for Integrated Development of Horticulture) offers subsidies for establishing Anthurium farms.
Conclusion
Commercial Anthurium cultivation presents a lucrative opportunity, but requires careful attention to microclimate management, propagation techniques, and post-harvest handling. The adoption of modern technologies like tissue culture and controlled environment agriculture can significantly enhance yield and quality. Government schemes like MIDH provide crucial support to farmers. Focusing on sustainable practices and value addition through processing and marketing can further strengthen the Indian Anthurium industry and compete globally. Further research into disease resistance and climate-resilient varieties remains vital for long-term success.
