Sowing propagation method of Calendula officinalis

Calendula is an annual or perennial herb, which is often used in flower beds. It has high ornamental value and economic value. The cultivation difficulty of calendula is not high, and it can be self-sown and grow fast. The editor will introduce to you the precautions of sowing calendula artificially, and friends who like it can learn about it together.

Calendula

The sowing of calendula is often sowed in autumn after mid-late September: the matrix is disinfected to disinfect the substrate used for sowing. The best way is to put it in a pan and stir-fry it so that any diseases and insects can be scalded to death. In addition, the seeds were sown at low temperature, put them in a 0 ℃ refrigerator for 24 hours, sowed in the open field after being taken out, the seedbed should be shaded, germinated in the middle of August, applied thin rotten fecal water once a week, and could blossom in late September.

First, sprout

Soak the seeds in warm hot water (the temperature is about the same as facial wash) for 3 to 10 hours until the seeds absorb water and expand. For common seeds that germinate easily, this work does not have to be done.

Second, sowing seeds

For tiny seeds that are difficult to pick up with hands or other tools, wet one end of the toothpick with water, stick the seeds one by one on the surface of the matrix, cover the substrate 1 cm thick, and then put the seeding pot into the water. The depth of the water is 1 inch 2pm 3 of the height of the flowerpot, allowing the water to soak up slowly (this method is called "pot soaking") so as not to wash the seeds up.

Third, management after sowing

After sowing in autumn, when you encounter a cold wave and low temperature, you can wrap the flowerpot with plastic film to keep warm and wet; after the seedlings are unearthed, the film should be opened in time, and before 9:30 every morning, or let the seedlings receive the sun after 3:30 in the afternoon, otherwise the seedlings will grow very weakly. After most of the seeds come out, they need to plant seedlings properly: pull out the diseased and unhealthy seedlings, so that the seedlings left behind have a certain space between each other; when most of the seedlings grow 3 or more leaves, they can be transplanted into the pot.

After sowing, the substrate was covered, and the thickness of the cover was 2-3 times that of the seed. After sowing, the sowing matrix can be wet with sprayers and fine-hole showers, and then when the pot soil is slightly dry, we should still pay attention to watering so as not to wash the seeds up; management after sowing: after sowing in autumn, when you encounter cold waves and low temperatures, you can wrap the flowerpot with plastic film to keep warm and humid. After the seedlings are unearthed, the film should be opened in time, and the seedlings should be exposed to the sun before 9:30 every morning or after 3:30 in the afternoon, otherwise the seedlings will grow very weakly; after most of the seeds come out, you need to plant seedlings properly: pull out the diseased and unhealthy seedlings so that there is some space between the seedlings left behind.
