Fennel from the sowing amount, seed treatment, sowing and other aspects of the seed to plant.

1, the amount of seed sown: generally 8-10 kilograms of seed per mu.

2, seed treatment: people usually say fennel seeds are double hanging fruit, containing two seeds, need to rub the seeds before sowing. Fennel can be dry seed direct seeding, soaking seed sowing and germination sowing. Greenhouse spring cultivation is generally dry seed direct seeding or dipping seed sowing, such as late sowing can be germinated sowing. Soak seed sowing should be soaked in 18 ℃ - 20 ℃ water for 24 hours; germination sowing should be soaked seeds placed in 20 ℃ - 22 ℃ environment germination, rinse with water once a day to wash away the mucus, 6 days or so can be sprouted.

3, sowing: the day of sowing, first in the leveling of the bed on the watering of the bottom, in order to achieve uniformity of sowing, can be divided into two sprinkled, sifted after sowing cover soil 1 cm thick, generally need to use about 5 kilograms of seed per acre. Generally planting a week or so will be able to come out of the seedling, after the seedling should be timely plowing and weeding, until the fennel seedling grows to about 5 centimeters when you want to timely inter-seedling, will be some of the growth of the weaker seedling elimination.

Field management of fennel

1, temperature management: after sowing to the seedling, closed greenhouse insulation against cold. Fennel seedlings, seedling height of 7-8 cm when the beginning of the wind, generally more than 22 ℃ in the morning when the wind, the afternoon below 20 ℃ when the wind closed; mid-morning 8 ℃ - 9 ℃ when the wind, until the afternoon 20 ℃ when the wind closed; later outside the lowest temperature more than 3 ℃ day and night ventilation, the daytime wind should be large, the wind should be small at night, the highest temperature during the day can not be more than 24 ℃, otherwise fennel easy to dry tip.

2, water and fertilizer management: seedling height of 20 cm or so, watering 1 time, the amount of water is moderate, combined with watering acres of urea 10-15 kg.

3, aphids: available 50% anti-phidwell wettable powder, 10-18 grams per mu, 30-50 kg of water spray.
