The culture soil of Cyclamen can be made up of humus soil, forest rotten leaf soil, cinder, etc. and a proper amount of calcium carbonate and other chemicals. This kind of soil is relatively loose, which is conducive to the growth of Cyclamen. When cultivating, pay attention to the size of the container, and gradually increase and do not use large pots to cultivate seedlings.
Cyclamen likes fertile soil, but doesn't like concentrated fertilizer. When turning basin, it needs to apply some basic fertilizer. Generally, it can apply fertilizer once a week or two, and pay attention to thin fertilizer frequently. After several months of vegetative growth period, organic fertilizer was applied to it, and water was used to water the flowers. When the temperature could not be controlled in summer, fertilization should be stopped.
Although Cyclamen is drought resistant, it is best to keep the soil moist during its growing season, and pay attention that there should be no water in the basin. Water frequently but less, don't be too wet. If summer is not dormant, normal watering can be carried out. It is necessary to keep the basin soil sweet and moist. After the beginning of autumn, it will enter the reproductive growth period. At this time, it is necessary to apply phosphorus and potassium fertilizer to control the growth of nutrition, promote the differentiation of flower buds and the flowering of pregnant buds.
The growth temperature of Cyclamen's forehead is suitable for 10-22 ℃, and it should be kept at 8-10 ℃ in the daytime and at night. If the night temperature is controlled at about 7-8 ℃, the flowers can bloom, but the flowering period will be slightly delayed; if it is lower than 6 ℃, the flowers will not bloom normally.
Temperature and light have a certain effect on the growth and development of Cyclamen. In the whole process, we need to start from the temperature and consider extending the flowering period. When the flowers decrease in late April, it is necessary to remove them from the greenhouse and cultivate them in a well ventilated place. Climate change, appropriate temperature and light will make Cyclamen grow a batch of scape and continue to bloom. In the Yangtze River Basin and its south, the leaves turn yellow gradually after May, which is the reflection of the temperature rise. At this time, it is necessary to control the watering. In summer, it is necessary to use cooling equipment to reduce the temperature of the environment.
When the temperature in summer is over 28 ℃, the bulbs of Cyclamen will start to dormant. The management of dormancy period is not good, and the bulbs are easy to dry or rot, so it is a difficult point for Cyclamen to grow safely in summer.
Strong seedlings are the best way for them to cross the summer. The annual seedlings are vigorous in growth and weak in dormancy in summer. During the summer, the management of fertilizer and water should be strengthened to form strong seedlings, so that the leaves are thick, many, and the color is thick and glossy. This kind of seedling has strong heat resistance. Colleagues should do a good job of cooling, cover the sunscreen, increase its ventilation, and spray water around the plant. After the end of August, cyclamen will enter the growth period, so it is necessary to strengthen the management of fertilizer and water.
