Cyclamen persicum can be propagated by seeds, which can keep germinating power for 3 years under dry, ventilated and cool conditions. Now let's introduce how to plant Cyclamen seeds
Cyclamen sowing 1. Cyclamen sowing method 1. Sowing time: September to October is the best sowing time.
2. Seed selection: select large and plump seeds.
3. Seed treatment: Cyclamen seeds are larger, about 100 seeds per gram, the general germination rate is 85-95%, but the germination is slow and the emergence is uneven. In order to promote germination early and orderly, soaking seeds can be used before sowing. Just soak the seeds in cold water for one day and night or in warm water at 30 ℃ for 2-3 hours, then wash away the adhesion on the surface of the seeds, wrap them in a wet cloth to promote germination, keep the temperature at about 25 ℃, and place them for 1-2 days. After the seeds germinate slightly, they can be taken out for sowing.
4. Sowing soil: loam, rotten leaf soil and river sand are mixed equally.
5. Sowing method: the distance of 1.5-2.0 cm was sown in shallow basin or shallow box, and the thickness of covering soil was 0.5-1.0 cm. Soak water in the basin, cover the glass, and place it at 18-20 ℃ for about 30-40 days. After germination, remove the glass in time and place it in a sunny and ventilated place.
6. Seedling Division: when the seedlings grow one true leaf, the first seedling division is carried out, and the plant spacing is 3.5cm, which is moved into the shallow basin. The basin soil is composed of rotten leaf soil 5, loam soil 3 and river sand 2. When planting, the top of the ball should be level with the soil surface. After planting, soak it with water and shade it properly. When the seedlings grow again, gradually give light, strengthen ventilation, do not make the basin soil dry, keep the temperature at 15 ℃ ~ 18 ℃, apply nitrogen fertilizer properly, pay attention not to make the fertilizer and water contaminate the leaf surface, so as to avoid leaf rot. Sprinkle water once after fertilization to keep the leaves clean.
7. Transplanting: when the seedlings grow to 3-5 leaves, they should be transplanted into a 10 cm basin. At this time, the proportion of basin soil can be changed to rotten leaf soil 3, loam soil 2, river sand 1, and the rotten cake fertilizer and bone meal can be used as base fertilizer. After March to April, the temperature gradually increased, the leaves and leaves of the plant increased, the growth became more vigorous, and the demand for fertilizer and water also increased. Therefore, the management of fertilizer and water should be strengthened, the basin soil should be kept moist and the ventilation should be strengthened, the strong sunshine in the afternoon should be covered, the temperature should be kept as low as possible, and the rain and the basin soil should be prevented from being too wet, so as to avoid the root rot. It should be planted outdoors in the shade with rain proof equipment.
8. Fixed value: planted in 20 cm basin in September, bulbous roots can be exposed about 1 / 3 of the soil surface for planting. The basin soil is rotten leaf soil 3, loam soil 2 and river sand 1, but the basal fertilizer should be increased. In order to promote flower bud differentiation, more phosphorus and potassium should be applied. When the buds appear in November, top dressing should be stopped and sufficient light should be given. The flowers begin to bloom in December and reach full bloom in February of the next year. That is to say, it takes about 13-15 months from sowing to flowering.
Cyclamen seed germination II. Key points of Cyclamen maintenance (1) watering should be wet rather than waterlogging: always keep the soil moist, and the root should not be waterlogged.
(2) Fertilization should be thin rather than thick: thin fertilizer should be applied every ten days in growth period, and less or no nitrogen fertilizer should be applied in flowering period.
(3) The light should be warm rather than hot: the sunlight should be warm and warm, and avoid direct sunlight and shade in summer.
