How to grow Florence fennel? The latest planting technique tutorial
Florence fennel is a variety of fennel. It has a novel appearance, is rich in nutrients, and has a unique aroma. It is exceptionally delicious whether eaten raw or cooked, making it a high-quality health vegetable. As it becomes more and more popular, more people are growing it, so how should Florence fennel be grown? Let's take a look together.
1. Sowing and raising seedlings
Florence fennel can be sown directly or transplanted as seedlings. In actual production, to cultivate strong seedlings, seedlings are generally raised and then transplanted. For spring cultivation, the seedling raising time is generally early to mid-March, usually in greenhouses and sun-facing seedbeds; for autumn cultivation, seedlings are generally raised from July to August; for winter seedling raising, seedlings are generally raised from January to February in protected areas. Before raising seedlings, the seeds need to be sprouted. First soak the seeds for 24 hours, then place them in a greenhouse environment at 20-25 degrees to sprout. During sprouting, rinse them once a day with warm water, and they will sprout within a week. Then sow at 4 grams of seed per square meter. After sowing, cover with a layer of fine soil. After emergence, maintain 20-25 degrees during the day, with the maximum not exceeding 28 degrees, and maintain around 15 degrees at night. At the same time, thin and retain seedlings in time. When they grow to 5-6 true leaves, they can be transplanted.
2. Field planting
The spring field planting time for Florence fennel is early to mid-April. When the temperature stabilizes at around 15 degrees, it can be planted out; the autumn field planting time is from August to September; the winter-spring protected area field planting time is from February to March. Before field planting, apply 3000 kg of organic fertilizer, 20 kg of diammonium phosphate, 15 kg of potassium sulfate, and 20 kg of urea per mu, then finely prepare the soil and make beds. Generally, about 5500-6600 plants are planted per mu.
3. Field management
After field planting, water promptly to promote seedling recovery. Half a month after field planting, apply 10 kg of urea per mu. After 25 days, apply 15 kg of urea per mu with irrigation water. After an interval of one week, apply 7-10 kg of urea per mu. The main diseases and pests of autumn fennel include powdery mildew, gray mold, aphids, and cabbage caterpillars, so prevention and control work should be done well.
4. Timely harvesting
For autumn fennel, 40-50 days after field planting, when the bulb has fully expanded in autumn and the outer scales are white or yellowish-white, it can be harvested. Harvesting too early or too late will affect yield and quality. When harvesting, first select those that have expanded earlier and bring them to market in batches. If saving seeds, it needs to be isolated from non-bulbing fennel stems.
