Cyclamen is native to Europe, prefers warm winters and cool summers, good sunshine, but avoid strong sun exposure, if the sun is too strong, some or all of the leaves will be burned by the sun, manifested as yellowing of the leaves, and in severe cases, the burns are as large as the palms of the hands, resulting in the growth of the plant stagnant and death.
Cyclamen should be cultivated on loose and fertile soil. Before cultivation, sufficient base fertilizer should be applied, and the base fertilizer should be rotted poultry manure, cake fertilizer, and compound fertilizer. When applying, it is advisable to bury a ditch in the soil, and cover the soil after fertilization to prevent fertilizer volatile pollution.
Cyclamen grows by absorbing large amounts of nutrients such as nitrogen, phosphorus, potassium, sulphur, calcium, magnesium and various trace elements from the soil. During the growing period, the soil should be loosened once a week so that the potting soil is in a condition of good ventilation and sufficient nutrients. Loosening soil can bring the surface soil into contact with the air, which is conducive to the decomposition of soil organic matter by aerobic bacteria and increases the effective nutrients in the soil. Cyclamen watering is very important, as insufficient water can cause bulbs to shrink and fall leaves, but too much water can suffocate the roots, affect nutrient absorption, aggravate premature plant senescence, and reduce or even wilt in summer. The amount of watering should be controlled in the morning and evening every day. The air humidity should be kept at around 70%. In addition, pay attention to proper fertilization and light regulation.
In late spring to frost should be watered and placed in a sunny, cool and ventilated place, this low temperature period is mainly to control the height of the plant, in order to facilitate overwintering. In winter, the temperature should be kept at 18°C~20°C during the day and above 15°C at night. Due to the slow growth or semi-dormancy of cyclamen in summer, some flower lovers will blindly cut off water and fertilizer at this time, resulting in a serious drying of the soil surface and the death of the spheres. In fact, in the high temperature period of summer, as long as the ventilation is strengthened and the air humidity is maintained, the required moisture and nutrient requirements can be met.
Cyclamen breeding method
Cyclamen is mainly propagated by dividing balls, but it can also be propagated by seeds. Spherical propagation is generally cultivated in autumn, and after spring growth and development, the flower color is colorful and colorful. Autumn cultivation is characterized by early flowering and generally blooms between New Year's Day and Spring Festival. The specific practice is: cut off the cue ball side buds in autumn about 9~10 months, break them into two sections by hand when planting, and then top dressing after normal growth can be flowered one after another. It can also be planted with digging, and it can be dried in a cool place for a day before planting. Sowing and propagation are generally not used, and the flowering is late and the number is small.
In addition, there is also a method of grafting and propagation: grafting seedlings are carried out by using the characteristics of plants such as radish that grow quickly and are easy to reproduce. The specific method is: choose dwarf varieties of radish as rootstock, scion should be cut from the mother plant of young spherical buds after grafting, after careful management, the following year in April ~ May can be flowered. The benefits of grafting are not only dwarfing, but also increasing plant resistance. The specific operation method of grafting: flatten the top of the rootstock, and tie the small buds of the scion on the rootstock with plastic tape.
In short, there are many different cultivation techniques and propagation methods for cyclamen, and each method needs to be used flexibly and carefully taken care of in order for cyclamen to grow healthily and produce beautiful flowers.
