Common varieties include large flower flat petal type, wrinkled leaf round petal type, wavy petal type and so on. Cyclamen annual tubers usually have a cluster of leaves at the top, usually with 30 to 40 flowers. The flowering period is during the Spring Festival, usually sown in autumn, and it blooms in 65438+February, reaching its peak in February of the following year, and the flowering period can be extended to May. Using some flower-promoting techniques in cultivation can shorten the cultivation period and make it blossom ahead of time.
Gain weight.
Cyclamen persicum is a kind of fertilizer-loving flower. Potting with peat or chaff ash 1: 1, or completely decomposed sawdust and peat 1: 1. When it is prepared, it is combined with decomposed cake fertilizer and superphosphate, and a certain compound fertilizer is used as the base fertilizer. The soil in the flowerpot is rich in humus and the plants grow well. Topdressing with 2% potassium dihydrogen phosphate in autumn and spring is 65438 0 times respectively, so it is not suitable to use high nitrogen fertilizer. It is very important to maintain the leaves before flowering. If the leaves are not long enough to bloom well, and too much nitrogen is applied in June 5438+065438+1October, there will be a phenomenon of excessive growth, only leaves grow, and there are many leaves that are not flowering or flowering. It is necessary to adjust the fertilizer water, don't water it too much, and spray water on the leaves and the ground when wet and dry alternate. Apply phosphorus and potassium fertilizer, and fully see the light, and remove the long leaves, lobules and redundant leaves in the middle, so as to facilitate the rapid formation and centralized flowering of flower buds, which can bloom about 15-20 days in advance.
Maintain proper temperature conditions.
Cyclamen is a low-temperature bulb flower, and likes a cool, humid and sunny environment. The optimum growth temperature is 65438 05℃ to 20℃. It is most afraid of hot weather in summer, especially the old ball. Although the new ball has strong resistance, it also stops growing in hot climate and is in a semi-dormant state. It is not resistant to high temperature. If the temperature is too high, it will go into hibernation. Under the environmental conditions of about 20℃ during the day and 65438 00℃ at night, the temperature at seedling stage can be slightly lower. In addition, the temperature of flower bud differentiation and pedicel elongation is slightly lower, which is beneficial to flowering. The temperature of flower bud formation is 65438 06℃, and the temperature is higher than 30℃, which leads to poor growth or plant growth stagnation in semi-dormancy. If low temperature conditions are created in summer, you can stay awake, which is conducive to flowering.
Extend the lighting conditions.
Cyclamen likes sunshine, and extending the illumination time can promote it to blossom ahead of time. When the leaves grow to about 10- 12 in potted plants, they begin to enter the stage of flower bud differentiation, and the light intensity is the decisive factor in the process of leaf bud transformation to flower bud. At this critical moment, it is very beneficial to appropriately increase the temperature difference between day and night and the light intensity.
You can move the flowerpot to a place with strong scattered light and let it receive light sooner or later. When the light is insufficient, it will affect the flowering of plants. Therefore, when the light is insufficient, artificial lighting measures should be taken, and the flowerpot should be maintained in a sunny place as far as possible.
Cyclamen enters the peak growth period in autumn, and the young leaves on the bulb will quickly grow into dense Ye Qun after seeing the light, which will delay the development of the young buds below because of insufficient light. Therefore, the leaves in the middle of Ye Qun should be thinned properly, so that the buds below can develop normally, which is conducive to more flowers.
Hormone therapy.
When Cyclamen cyclamen shoots appear, spraying gibberellin (920) lightly twice a day with 1-2 can make them blossom about 10- 15 days earlier.
Flowering period management.
During flowering in winter, flowerpots should not be placed too closely. To keep a certain distance, to prevent the leaves from overlapping each other, affecting the light, and to avoid the leaves from being long and scattered due to insufficient light. At the same time, the flowerpot should be rotated frequently, so that leaves in different directions can receive light, produce more organic matter for flowering, and keep the full plant shape of cyclamen, thus prolonging the flowering period and improving the ornamental effect.
