is afraid of both high temperature and severe cold, and avoids strong sunlight. Spring, autumn and winter are the seasons of growth and prosperity, and summer is the dormant period. The appropriate growth temperature is between 15℃ and 20℃. The temperature below 10℃ is lower than 10℃, and the flowers are easily withered. When the temperature exceeds 30℃, the plant enters a dormant state. When it exceeds 35℃, the plant is prone to rot and dies. Therefore, cyclamen should grow in slightly acidic sandy loam and greenhouse environments rich in humus and well-drained.
cycla is mainly used to reproduce seeds. The seeding time varies depending on the characteristics of the variety, the temperature conditions after sowing and the expected flowering time.
autumn sowing time is from September to October, which is also the best sowing season for Cyclops. Because this can help the seedlings of cyclamen to avoid the hot summer and cold winter. Spring sowing time is from January to February (there are the soil thawing in March to April).
When seedlings grow 2 to 3 real leaves, transplant them in time. After hysteresis transplantation, the cyclamen plant is slender and thin, unable to form strong bulbs, and cannot bloom normally.
Cyclamen's colors include white, pink, rose red, purple, orange, red, red, and red edges and white hearts. Some varieties also have fragrance. Because the flowering period is long, it can be enjoyed for a long time. It is very good to use flower beds to decorate flowers on holidays, or to use accompanying flowers in hotels, shopping malls or to place them in the room. It is very good and is very popular with people, so its commercial production added value is very high.

The abnormal dead tree of Cyclamen is strongly related to the "4 kinds of diseases":
During the planting process, due to the influence of various conditions such as temperature and humidity, Cyclamen will suffer from bacterial leaf rot, soft rot , withering disease, leaf spot disease, anthrax , bacterial bud rot, fungal gray mold, mosaic virus disease, root knot nematode disease and other diseases.
But the abnormal death of Cyclops is strongly related to the "4 diseases". That is, Cyclops grey mold disease, Cyclops bacterial soft rot, Cyclops virus disease, and Cyclops root knot nematode disease.
(I) cycla gray mold :
cycla ginger gray mold is a common fungal disease during cycla ginger cultivation. The hazardous parts are mainly on the leaf petals, pedicels and petals. A typical pathogenic feature is that under high humidity conditions, a gray mold layer grows on the affected area.
When the disease occurs on the leaves, dark green water-like spots appear and spread to the entire leaves until the whole leaves turn brown and dry. After the petiole pedicels become ill, they first turn brown and sag in water-like shape, and finally turn brown and dry.

Cyclamen's disease is related to the influence of many factors such as heavy soil water accumulation, poor drainage of air, humid air, young and tender and long-lasting plants. During the planting process, attention should be paid to the ventilation and light transmission conditions between plants and the influence of temperature and humidity.
On the premise of accurately identifying the disease, 50% Trichoderma Niacinamide Water Dispersion Granules 1000~1200 times, 50.5% Niacinamide Bernardine Wettable Powder 800~1200 times, 55% Isophyllum 800~1200 times, 55% Isophyllum 800~1200 times, or 50% 4 Asophyllum Asophyllum 5 Asophyllum 10~15g/barrel water, or 75% Isophyllum 25g~30g/barrel water dispersion Granules 25g~30g/barrel water dispersion Granules 10~10g/barrel water dispersion Granules 25g~30g/barrel water, and the front and back sides of the leaves should not drop the medicine solution. When the disease is serious, you can use it for 2 to 3 consecutive times to correct the disease.
(II) Cyclamen bacterial soft rot:
is a typical Cyclamen bacterial disease . When cyclamen came to the disease, they became ill from the petioles and pedicels near the surface of the leaves, and water-like lesions appeared, which then turned to brown soft rot, and the rhizomes and underground tubers rotted and smelled. When the rhizomes rot, it affects the transportation and transmission of nutrients and water from the root system to the above-ground plants, causing the above-ground plants to wither and die. Off-white bacterial pus appears in soft rot areas. It is very easy to get sick when the air is humid.

Commonly used Cyclade bacterial soft rot in production include 80% allicin water agent 1000~1200 times solution or 51% simazin qingkulin wettable powder 800~1000 times solution, or 20% thiabacterium copper (Longke) suspension 500 times solution, or 30% copper oxychloride suspension 400~600 times solution, or 77% copper hydroxide 600 times solution spray stems and leaves treatment or root irrigation can effectively correct Cyclade bacterial soft rot.
(III) Danger of Cyclamen virus disease:
Due to the danger of virus invasion, Cyclamen leaves are curled and wrinkled and mottled, the leaves are small and thick, the flowers are deformed and stripes appear on the petals, and the dwarf tubers of the plant degenerate, greatly reducing the ornamentality of Cyclamen.
The commonly used cyclagra virus disease agents and the concentrations used are: spray 43% triazole nucleoside dextene hydrochloride morpholinoguanidine hydrochloride water agent 800~1200 times liquid, or spray stems and leaves for 31% apyridine pyridine hydrochloride 1200~1500 times liquid, or 20% morpholinoguanidine hydrochloride suspension 300~400 times liquid, or 0.5% shiitake polysaccharide water agent 800~1000 times liquid.

However, the occurrence of Cyclops virus disease is related to the harm of aphid and poison transmission. Therefore, when using viral agents (inhibitors), it is best to use them in combination with pesticides that kill aphids, so that the comprehensive prevention and control of diseases and pests of Cyclops will be more thorough. Such as 10% pyraphine water dispersion granules.
(IV) Cyclamen root knot nematode disease:
Cyclamen root knot nematode disease is the main disease of the roots of cyclamen flowers and is a disease caused by the harm of root nematodes. Its typical feature is that tumors form on its root system (actually a kind of gall ), and nematodes suck the juice on the root system in the tumor, causing cyclamen to grow and develop poorly. The plants on the ground turn yellow, thin, shrink and do not grow due to lack of nutrients.
As the condition worsens, cyclamen dies, along with the worm tumors on the root system. The source of nematodes is related to soil, bulbs, and long-distance transportation, and the application of fully decomposed farm organic fertilizer.
The commonly used chemical agents for the prevention and treatment of root knot nematode disease in
The concentration of commonly used chemical agents and the use is: 20% thiazolytein water emulsion 1500~2000 times liquid root seed, or 1.5% methyl chlorocyanide granules (or 50% calcium cyanamide granules) and base fertilizer or mixed soil to apply to the roots of cyclamide.
Conclusion: During the planting process, the disease occurs far more than the above mentioned types, as well as other fungal or bacterial diseases, viral diseases and non-invasive diseases. However, the above four diseases are most harmful to cyclamen planting. We must strengthen the daily management of cyclamen and comprehensive prevention and control of pests to improve the planting benefits of cyclamen.
