How does dandelion spread its seeds?

Dandelions spread their seeds by the wind. Dandelion flowers are yellow, after a period of time, petals fell, the receptacle on the growth of a white ball. The seed is Obovate-lanceolate in shape, dark brown in color and with white crown hairs. A gust of wind blew, and the seeds fluttered in the wind, like parachutes, into the distance. As soon as the wind stops, the seeds will fall and take root in a new place.

Planting methods of dandelion seeds

1. Soil: it should be planted on loose, fertile and well-drained sandy loam. Apply 2000-3500 kg organic fertilizer per mu, mix 15 kg of calcium superphosphate, then turn the soil 20-25 cm deep, level off and rake fine, and make a flat border with a width of 1.2 meters and a length of 10 meters.

2. Sowing: you can sow seeds at any time from spring to autumn, and sow seeds in the greenhouse in winter. Shallow trenches were opened in the border before sowing, with a distance of 12 cm and a width of 10 cm. Sow the seeds in the ditch, cover the soil 0.3 cm 0.5 cm after sowing, and then cover the grass to keep warm. The seedlings can emerge in about 6 days, and the cover grass will be removed when the seedlings emerge.

3. Field management

The main results are as follows: (1) Inter-seedling and fixed seedling: the seedling spacing is 3-5 cm in 10 days after emergence and 8-10 cm in 20-30 days.

(2) Intermediate ploughing and weeding: the first intertillage weeding can be carried out 10 days after emergence, and then once every 10 days until the ridge is closed.

(3) watering: properly control moisture after emergence to make seedlings thrive and prevent overgrowth and lodging; keep the field moist during the rapid growth period of leaves to promote the vigorous growth of leaves; water once before winter, and then cover horse dung or wheat straw to survive the winter.

(4) fertilization: apply fertilizer twice during the growth period, sprinkle 2500 kg of organic fertilizer and 20 kg of calcium superphosphate per mu after winter, and apply 10 kg of urea and 8 kg of superphosphate per mu after turning green in the next spring.

(5) Diseases and insect pests: dandelion has strong resistance to disease and insect pests, so it is generally not necessary to control diseases and insect pests.
