Sowing method

Seed selection

Before sowing, seeds should be selected to jump out the withered and rotten seeds. This step is directly related to the success of sowing. Mainly according to the following three methods:

① Select the seeds that are born in the current year, because the longer the amount of seeds is kept, the lower the germination rate is

② Choose a large, full seed without deformity or deformity

③ Choose seeds that are free from pests and diseases

Disinfection

The disinfection here includes two aspects: one is to disinfect the seeds, soak the seeds in hot water at 60 ℃ for 15 minutes, and then put them into warm water to promote germination for 12 ~ 24 hours. The second is to disinfect the sown soil. The best way is to fry it in a hot pot. The second is to soak it in potassium permanganate solution and dry it in the air

Budding

Soak the seeds in warm water for 12 ~ 24 hours until the seeds absorb water and expand slightly. Remove them and dry them before sowing

Sow

Clamp the seeds with tweezers, put them into the soil one by one, with a spacing of about 1 cm, and cover with 2 ~ 3 cm thin soil

After sowing, put the flowerpot in water, and the depth of water is 1 / 2 ~ 2 / 3 of the height of the flowerpot. Let the water slowly soak the soil

spray the surface of the basin soil wet, after the basin slightly dry can spray water, pay attention to the intensity of watering should not be too big, so that the seeds will be washed up. p>

Curing after sowing

Heat preservation and moisturizing

There is no strict limit on the sowing time of two-color jasmine. It can be sown in late autumn, early spring or winter. Therefore, in case of low temperature and dry weather after sowing, wrap the whole flower pot with plastic film to keep warm and moisturize and promote seed germination

Replenish sunshine

After the seedlings grow, the film shall be removed in time. Before 9 a.m. and after 3 p.m. every day, the seedlings shall be fully exposed to the sun to prevent the seedlings from growing thin

In addition, when some seedlings grow to a certain time, they should be separated, and the thin seedlings should be uprooted to save nutrients for the healthy seedlings
