Breeding method
Propagation method
1. Sowing
It is best to sow in autumn in September. There are 700 seeds per gram. The suitable temperature for germination is 13℃ to 16℃. Germination takes 12-15 days, and it takes about 100-110 days from sowing to flowering.
2. Cuttings
Carry out in May-June, cut off the sprouted branches at the base of the plant, insert them into peat, keep the air moist, and take root 15-20 days after cutting. The survival rate is high.
3. Branching
It is usually done after flowering. Cut off the side branches with adventitious roots or the new branches with roots that sprout from the rhizomes. They can be potted directly and placed in semi-shade. Restoration everywhere.
Notes
1. Temperature
The suitable temperature for germination of pansies is 18-21℃. Germination takes 7-10 days under dark conditions. The temperature for growth is The temperature is 10-13℃, and flowering occurs 14-15 weeks after sowing. If the temperature is too high during sowing, it will affect the germination of seeds and the growth of seedlings, resulting in a low seedling rate. The soil temperature of pansy seedlings during the growth stage is 15-24°C. The lower the temperature, the slower the growth of the plant and the stronger the plant.
2. Light
After sowing the pansies, use vermiculite to cover the seeds. Keep the soil temperature at 18-24°C and keep the medium moist. No light is needed before the bacon grows. Generally, 7 -Seedlings can emerge in 14 days.
3. Watering
Let the soil dry out before watering but avoid permanent wilting of the plant, which will also facilitate the growth of pansy roots. The pH of the soil should be maintained at 5.5-5.8, and some N fertilizer or potassium nitrate fertilizer should be applied alternately.
