Time selection

Sowing in spring in the north, all over the south of the Huaihe River, sowing and seedling raising in autumn or spring

The autumn sowing period is from mid October to before freezing. The spring sowing can be selected before sowing wheat and after soil thawing& lt;

Substrate disinfection

Before sowing, the best way to disinfect the substrate is to heat at high temperature to eliminate bacteria and pests in the soil

First put 2-3cm thick coarse-grained matrix or ceramsite into the flower pot as the filter layer, sprinkle a layer of fully decomposed organic fertilizer as the base fertilizer, with a thickness of about 1-2cm, and then cover it with a layer of matrix, with a thickness of about 1-2cm

Seed treatment

Soak the seeds in warm water for 3 hours before sowing, so as to improve the germination rate

Specific steps

Because the seeds of evening primrose are relatively small, you can wet one end of the toothpick, stick up the seeds and put them on the surface of the substrate one by one

Then cover the soil, about 1 cm, and then put the sown flowerpot into the water. The depth of the water is one-half to two-thirds of the height of the flowerpot, and let the water soak up slowly

Follow up management

water is sprayed in the pot soil when it is sowed. p>

After sowing in autumn, in case of cold wave and low temperature, the flowerpot can be wrapped with plastic film to facilitate heat preservation and moisture retention; After the seedlings are unearthed, the film should be uncovered in time, and the seedlings should be exposed to the sun before 9:30 a.m. or after 3:30 p.m. every day, otherwise the seedlings will grow very weak

When most of the seedlings grow three or more leaves, they can be transplanted into pots
