How to sow and raise seedlings of flowers

Strong seedlings are cultivated only after sowing, and only with seedlings can they be used to raise flowers. Only by mastering the method of sowing and raising seedlings of flowers, can we raise seedlings successfully and cultivate beautiful flowers.

Preparation of flowers before sowing

1. Soaking seeds

The thinner seed coat can be soaked in cold water, the thicker seed coat can be soaked in warm water or hot water, and very small seeds can not be soaked.

two。 Prepare the nursery box / pot

The advantages of seedling pot are saving seeds, uniform nutrients, neat emergence of seedlings, easy to transplant, and easy to count the germination rate of seeds. Directly sowing in the soil, the soil temperature and humidity are difficult to control, the soil may have microorganisms that are not conducive to seed germination and growth.

3. Seedling substrate

The substrate with loose soil, good air permeability, good fertilizer and water retention and clean substrate can be mixed with peat soil, coconut bran and vermiculite.

4. Loading basin

Mix the matrix evenly and put it into a basin without compaction, just flatten the soil surface.

5. Watering

Control the amount of water, carefully pour through the basin soil, after watering, you can disinfect the soil with fungicides.

The sowing process of flowers

1. Sowing density

When sowing seeds in hole pots, sow 1 or more seeds in each hole, and sow 1-2 seeds per square meter in seedling pots.

two。 Sowing seeds

When the flower seeds are larger, they can be evenly scattered on the substrate, or you can choose strip sowing or on-demand sowing; when the flower seeds are small, you can mix the seeds with clean sand and sow them evenly.

3. Sowing depth and soil covering

The sowing depth is determined by the seed size and the light requirement of seed germination. generally speaking, the sowing depth of the seed is 2-3 times of the seed diameter.

4. Spray water

After sowing and covering the soil, use a fine spray nozzle to water thoroughly.

5. Overlay

Covering the seed plate with glass, plastic film and plastic film can maintain the air humidity and increase the temperature in winter. The film can not be covered in the summer when the temperature is high, and the film must be ventilated on both sides.

Management of flowers after sowing

1. Temperature

Generally speaking, the germination temperature of seeds is between 20 and 25 degrees, and the appropriate temperature environment should be given according to the requirements of flower varieties.

two。 Humidity

Replenish less water when raising seedlings in winter and replenish water at any time according to the actual situation in summer.

3. Light

Generally speaking, seeds are easy to germinate under light conditions, and seedlings will grow if they are not exposed to light after germination.

4. Remove the cover

The mulch should be removed in time after seed germination, but the temperature of the substrate should be maintained to make the ungerminated seed extend its shell.

5. Transplant

When the seedlings grow to a certain size, they should be transplanted and cultivated in time, otherwise the seedlings will grow too much or the production will be delayed.
