Dandelion is a perennial herb of Compositae. A flower head with white crown hairs on its seeds, which floats to a new place with the wind after flowering and breeds new life. Its flowering period began in early April and entered the full fruit stage in early May. The full fruiting period lasts about 15 days, with sporadic flowering throughout the year and a concentrated fruiting period from September to June. So, in almost a year, you can see delicate little yellow flowers and flying parachutes.

Extended data:

Dandelion is a perennial plant. In the wild, biennial plants can blossom and bear seeds. In early summer, the number of flowering and fruiting seeds increases with the growth years. Some plants open more than 20, and excellent varieties can open more than 20. After flowering, the seeds will mature in 13 ~ 15 days.

The shell of the disk changes from green to yellow-green, and the seeds can be harvested from ivory to brown. Don't wait for the disc to crack before harvesting, otherwise the seeds will easily fly away and lose a lot. Generally, the number of seeds per flower head is above 100. The 1000-grain weight of Taraxacum macrophyllum seeds is about 2g, and that of Taraxacum microphyllum seeds is about 0.8 ~1.2g..

When collecting seeds, you can take off the dandelion's disk and store it indoors for a day. After the disk is completely scattered, dry it in the shade for 1 ~ 2 days until the seeds are half dry, rub off the fluff at the tip of the seeds by hand, and then dry the seeds for later use. ?

In places with abundant wild dandelion resources, the roots of wild dandelion can also be directly controlled for cultivation. Usually in June 5438+10, after digging the roots, plant them in the greenhouse with row spacing of 8 cm× 3 cm. After planting, water enough, and new leaves will grow in February of the following year. At this time, organic fertilizer is applied again, and the leaves can be picked and listed when they grow to a certain extent.
