The planting method of fennel

Fennel has strong adaptability and short growth period. It can be sowed and cultivated from March to September, and it is suitable to be planted in flat beds. In order to make the emergence of seedlings quickly and neatly, it is best to soak the seeds to promote germination before sowing. The method is to soak the seeds for 24 hours, then rub the seeds by hand and rinse them several times until the water is clear, spread the wet seeds on a sack or straw mat, cool them in a cool place, then put them in an earthen basin, cover with a wet cloth and accelerate germination under 16 ℃ ~ 23 ℃.

Fennel is often sown by wet sowing, that is, leaving cover soil when making beds, watering bottom water before sowing, spreading evenly after sowing, and covering soil. Fennel has a small leaf area and is very suitable for close planting, with a sowing rate of 3-5 kg per mu. If you sow dry seeds, you should pay attention to watering small water frequently after sowing, so as to keep the border surface moist to facilitate the emergence of young buds. If there is not enough water during the emergence period, the phenomenon of seedling deficiency is easy to occur. After the seedlings are unearthed, they grow slowly and are easy to breed weeds in the field, so we should pay attention to weeding in time. The seedling stage should not be watered too much, but keep the border surface dry and wet. The seedlings are generally harvested at one time. If you plan to harvest many times, you can combine weeding seedlings, the seedling distance is 5-6 cm, when the plant is about 10 cm high, watering should be frequent, and combined with watering to apply available nitrogen fertilizer. When the plant is about 30 cm high, it can be harvested.
