Select seeds and conduct seed treatment. Select the full and glossy brown seeds, put the seeds in the water at about 30 ℃ for 3-4 hours, and then sow them. The seeds bloom about 10 days earlier than the seeds without soaking.
Cyclamen belongs to the plant that likes to wet and is afraid of waterlogging. Too much water is not conducive to its growth and development, and even causes rotten roots and death. Therefore, it is enough to keep the soil moist every day, and the amount of water should not be too large.
Cyclamen likes sunshine, prolonging the time of illumination can promote its early flowering. Therefore, cyclamen should be placed in a sunny place for maintenance. When the young buds of Cyclamen were treated with 6 hormone, 1 mg /kg gibberellin was used to spray on the young buds gently, 1-3 times a day, which could flower more than 15 days earlier.
Cyclamen can't stand high temperature. If the temperature is too high, it will go to sleep. Therefore, temperature has a great influence on Cyclamen. In general, cyclamen is suitable to grow at about 20 ℃ in the daytime and 10 ℃ in the evening. The temperature of seedling stage can be slightly lower. In addition, the temperature of flower bud differentiation and stem elongation is slightly lower, which is conducive to flowering. Cyclamen entered the dormancy stage in summer because of the high temperature. If the low temperature conditions were created, it could not be dormant, which was conducive to flowering.
Cyclamen is also a fertilizer loving plant. First of all, we should start from the soil. The soil in the flowerpot is the fertile sandy loam with more humus. The basin soil should be changed once a year, and the 2 ‰ potassium dihydrogen phosphate should be applied once a year in spring and autumn. High nitrogen fertilizer should not be applied, and flowers can bloom 15-20 days in advance.
