Planting time of garland chrysanthemum
The whole garland chrysanthemum plant has a special fresh aroma, which has a unique repellent effect on pests and diseases. Therefore, pesticides are rarely sprayed, making it an ideal pollution-free vegetable. It is a semi-cold-tolerant vegetable, and it grows best in a cool and mild environment where the relative soil humidity is kept at 70%-80%. Under suitable temperatures, it can be sown all year round. In recent years, protected cultivation in winter, spring and autumn has become increasingly common. After sowing, it is generally harvested in 40-50 days; when temperatures are low, the growing period is extended to 60-70 days.
1. Planting time is generally best in spring and autumn cultivation. In the south, it can be cultivated in all three seasons: spring, autumn and winter.
2. Sowing methods can be direct sowing or seedling transplanting, mostly direct sowing. Spread the seeds evenly on the growing soil, cover with soil about 1 cm deep after sowing, water thoroughly, and keep warm and moist. Seedlings emerge in 4-5 days, and when the seedlings grow to 2-3 true leaves, thinning is needed.
3. Sowing containers For growing garland chrysanthemum on a balcony, rooftop, or courtyard, the cultivation containers that can be used include flower pots, wooden basins, professional cultivation boxes, foam plastic boxes, etc. The cultivation layer depth should preferably be 20 cm.
Sowing and seedling raising
1. Seed treatment: 3-4 days before sowing, soak the seeds in 50-55 hot water for 15 minutes, then soak for 12-24 hours, and place them in a warm place at about 25°C for germination. During germination, rinse once a day with clean water. If they are new seeds, place them in advance at a low temperature of 0-5°C, and after about 7 days dormancy will be broken.
2. Sowing selection: For protected cultivation in spring, sow and raise seedlings in a hotbed in late March or April; for open-field cultivation in spring, sow and raise seedlings in a hotbed in mid-April; for open-field direct sowing in spring, sow in early May under small arched sheds or plastic film; for summer and autumn cultivation, sow in batches and stages in cold frames or open fields, with one sowing period every 7-10 days.
3. Sowing method: Depending on the cultivation method (direct sowing or seedling transplanting), adopt broadcast sowing or drilling. For broadcast sowing, the seeding rate is 60-70 kg per hectare; for drilling, sow at a row spacing of about 10 cm, with a seeding rate of 30-37.5 kg per hectare. For early spring seedbed seedling raising, cover with medicated soil after sowing to prevent sudden death disease. The seedling age should preferably be 20-0 days, and 3-4 true leaves is the suitable time for planting out.
Planting out and field management
From sowing to sprouting and emergence generally takes 5-7 days. During germination, pay attention to keeping moisture and preventing the soil from drying out. When the seedlings are 2-3 cm tall and have 1-2 true leaves, carry out thinning and field seedling pulling so that the plant spacing remains 1-2 cm. Also carry out shallow intertillage. When the seedlings reach the 3-4 true leaf stage, plant them out; the external or greenhouse temperature for planting out must stably pass 10°C. The plant spacing for planting out or final thinning should be 4-6 cm. Water once during the first thinning, and water again after final thinning, and apply quick-acting nitrogen fertilizer with the water. After that, thinning and harvesting can be done in stages.
