An Introduction to Common Crown Daisy Varieties and Seedling-Raising Methods
Crown daisy is native to China and is a semi-cold-tolerant vegetable. Because of its rich nutrition and edible value, it is called the "emperor's vegetable," and crown daisy has always been a delicacy of the ancient Chinese imperial court. As crown daisy has many values, its cultivation prospects are naturally very broad, so many farmers grow crown daisy. But if you want to grow crown daisy well, you still need to put in enough effort in areas such as variety selection and seedling-raising methods.
Common crown daisy varieties
Crown daisy can generally be divided into two major types: large-leaf and small-leaf. Large-leaf crown daisy grows slowly, has a long growth period, and matures relatively late. It is suitable for planting in the south and is mainly grown for its leaves. Small-leaf crown daisy grows quickly, matures early, and has strong cold tolerance. It is suitable for cultivation in the north. Its quality and yield are not as good as large-leaf crown daisy, but its texture is firmer and its aroma is strong. Common varieties are as follows:
1. Shanghai Round-leaf Crown Daisy: A local Shanghai variety, a large-leaf type, with shallow leaf-margin indentations. It is mainly grown for its leaves, has strong branching ability, and high yield.
2. Haozi Stalk: A Beijing farm variety. It is a small-leaf variety grown for its tender stems and leaves, with relatively strong cold tolerance and relatively high yield.
3. Variegated-leaf Crown Daisy: A local Shaanxi variety. Its leaf flesh is relatively thin, it branches more, has a strong aroma and good quality, and is suitable for growing in solar greenhouses and plastic tunnels.
4. Broad-leaf Crown Daisy: Introduced from Taiwan, China by Known-You Seed. Its leaves are large and thick, it is not tolerant of high temperatures, is relatively tolerant of drought and waterlogging, and has few pests and diseases. It is suitable for growing in solar greenhouses and plastic tunnels.
5. Xiangju No. 3 Crown Daisy: Introduced from Japan, a medium-leaf type. The leaves are slightly larger, the leaf color is dark green and glossy, the branching ability is strong, the yield is high, and it is resistant to downy mildew.
Crown daisy seedling-raising methods
1. Making beds
When making beds, the bed width is generally required to be about 1.5-1.8 m, and the length can be flexibly determined according to the actual situation of the plastic tunnel. Use a rake to break the soil into fine particles and level it. Then you can sow.
2. Soaking seeds to promote germination
Carry out germination promotion 3-4 days before sowing. Soak the seeds in warm water at 30°C for 24 hours, then rinse and dry them, and place them under conditions of 25°C to promote germination. Rinse once a day. After 3-4 days, once the seeds have sprouted, they can be sown.
3. Sowing and thinning seedlings
Because crown daisy plants are small and have a short growth period, they can be intercropped or relay-intercropped with other vegetables. In production, direct sowing, broadcast sowing, and drilling can all be used. For broadcast sowing, the seeding rate is generally 3-4 kg per mu, and for drilling, the row spacing can be controlled at about 10 cm.
Crown daisy can emerge about one week after sowing. When the seedlings grow to 2-3 true leaves, thinning should be carried out. You can thin by hand directly, pulling up the seedlings that are too densely packed, and keeping the remaining seedlings at a plant and row spacing of about 4-6 cm.
4. Transplanting
Practice has shown that transplanted seedlings grow faster than directly sown seedlings. When transplanting, use a sickle to lift the seedlings and put them into a prepared basin. Then transplant them into the prepared field, with a plant and row spacing of about 4-6 cm. After transplanting, water thoroughly once, and apply a nitrogen fertilizer once 20 days after transplanting.
The above is all the content introducing crown daisy varieties and seedling-raising methods. To grow crown daisy well, you must first understand crown daisy varieties and seedling-raising methods, and at the same time effectively combine them with subsequent daily cultivation and management techniques. By adopting effective methods when facing problems, you can naturally ensure the quality and high yield of crown daisy.
