Lily pollution-free planting techniques
Daylily, commonly known as the "day lily," is a perennial herb belonging to the Liliaceae family. This plant is widely consumed for its tender flower buds, which are rich in essential nutrients and considered a nutritious vegetable. It offers various health benefits such as enhancing brain function, promoting diuresis, improving beauty, nourishing the kidneys, preventing cancer, and helping to lower blood pressure. As a result, it is regarded as a valuable health food. To ensure high-quality production and meet the standards of eco-friendly vegetables, modern cultivation techniques have been developed. Below are the key practices for growing daylily effectively.
**1. Variety Selection**
Choosing the right variety is crucial for achieving high yield and quality. The selected varieties should be disease-resistant, fast-growing, and capable of producing high yields. Some popular varieties include:
- **Tongfeng Daylily (Chongqing):** A medium-maturing variety with a growth period of about 196 days. It has strong disease resistance, drought tolerance, and produces 250 kg of dried flowers per mu (667 square meters).
- **Tongchuan Early Daylily (Sichuan):** A precocious variety that matures in 155 days, with yellow buds that turn golden when dried. It yields around 170 kg of dried flowers per mu.
**2. Seedling Preparation**
Healthy seedlings should be selected from fields with vigorous growth, no pests or diseases, and high purity. When digging up rhizomes, remove old roots and cut back the roots to about 10 cm. Each bundle should contain 2–4 buds to ensure strong regrowth.
**3. Base Fertilization**
Before planting, the field should be deeply plowed (over 35 cm) and leveled. In paddy fields, proper drainage systems must be established. Before planting, apply well-rotted manure in trenches 30 cm deep, then cover with mature soil and add additional fertilizer before planting.
**4. Planting Density**
Transplanting is best done after harvesting buds, allowing the plants to recover and prepare for the next season. In fertile soils, plant 16,000–20,000 holes per mu, using a wide-narrow row pattern. Each hole should contain 2–4 ramets, spaced 40–50 cm apart. After transplanting, water the roots and cover with ash. Later, apply 100–200 kg of human waste per mu.
**5. Scientific Management**
- **Irrigation and Drainage:** Ensure proper drainage in spring to avoid waterlogging. During dry periods, irrigate regularly to maintain soil moisture and extend harvest time.
- **Fertilization:** Apply fertilizers in three stages—early spring, during flowering, and in winter. Use decomposed manure, bio-organic fertilizer, and foliar sprays like Pesticide 2000 to enhance plant health.
- **Harvesting:** Harvest between 12 PM and 2 PM for optimal quality. Avoid damaging buds and use clean containers to preserve freshness.
**6. Pest and Disease Control**
Common diseases include leaf spot, rust, and leaf blight, while pests such as red spiders, aphids, and beetles may appear. Prevention should focus on organic methods, with chemical treatments used only when necessary. For example, chlorothalonil can be used for leaf spot, and trichlorfon for beetles, but should be avoided 15 days before harvest.
By following these practices, farmers can successfully grow high-quality daylily while ensuring sustainability and environmental safety.
