The cyclamen is clean, soft and soft, and the fertile soil should not be too deep when it is covered with the ball. Otherwise, the bulbous roots are easily rot and should be 1/3 of the bulbs. After the new shoots are spread, fertilize the water once a week to promote rapid growth. The pots and soils should not be too wet. The watering should not be dry and not poured, and the pouring should be irrigated. If the watering is too frequent, the whole plant will die. .
Seasonal cultivation of Cyclamen:
November to March cyclamen bloom. Potted flowers should be placed in front of the south window or south of the closed balcony 1 meter to see the light. Above 10°C at room temperature, keep the potted soil moist, and pour 1% for half a month. Potassium dihydrogen phosphate type fertilizer can bloom continuously. In a room without heating facilities, pay attention to the protection against low temperatures and cold air, cover it with clear plastic bags and put it in a warm and bright place. When the cows have high temperatures, they should open the plastic bags to breathe. It can bloom from February to March.
From April to May, the flowering period will be completed. To remove the residual flowers as early as possible, gradually put the sun outside. Sprinkle 1% weekly. The compound fertilizer solution, the new leaves will soon grow, the old leaves fall off, and the bulbs will increase. If locust occurs, use a brush or a cotton swab to wipe off the water; if it is found that the leaves shrink and turn yellow, use carbofuran 1 to 2 grams along the edge of the pot to eliminate root knot nematodes.
June water and fertilizer management in May. Keep your shade at high temperatures. Some potted plants fall into dormancy after flowering until September. At this time should be placed in a cool, ventilated place, keep basin soil wet, can not be fertilized.
From July to August, when the north enters the high temperature season, the water should be stopped to control the fertilizer. Non-dormant plants should be placed on the east or north balcony, where they can be sunned for more than one hour in the morning, or they can be placed in the shade. At this time, new leaf buds and flower buds will grow on the top of the bulb. If rot occurs (grey mildew), use 75% chlorothalonil wettable powder 1000 times to spray and water.
In September, dormant bulbs started sprouting. More than two years old old plants can be changed soil, and newly purchased bulbs are also planted at this time. When planting, first pad 2 to 3 cm thick charcoal slag or ceramsite, coarse gravel, and then add culture soil. The old strains should be planted with soil. After the planting, the pelmeni must be low in the center and the bulbs should be exposed to 1/2 of the soil surface. After the next day, the bulbs should be irrigated and the shaded areas maintained. Sprouts increase light when they grow.
In October, when it enters a vigorous growth season, it should be put under the sun for conservation. Use 1% per week. The compound fertilizer solution was applied once, and a 1% potassium dihydrogen phosphate type foliar fertilizer was sprayed. Before entering the room, frost bloomed in November.
Breeding:
Cyclamen reproduction methods can be divided into two categories: sexual reproduction (sown propagation) and vegetative propagation (vegetative propagation), the latter including split tuber propagation, tissue culture propagation, and other forms of vegetative propagation.
The time for sowing is generally from September to October. Cyclamen Hi loose and fertile, well-drained sandy loam rich in humus, soil for sowing can be mixed with rot leaf, loam, river sand, or 3 parts of rot, 1 part of ash, 1 part of yellow mud. use.
Dividing tubers Although Cyclamen is a perennial bulbous flower, its tubers cannot naturally divide into sub-balloons, and thus cannot be divided and propagated like a typical bulbous flower. In terms of horticultural production, most of the cyclamen were cultivated in one or two years. One to two years old plants thrived and flowered widely. While plants above three years old, although the number of flowers increased, but the flowers became smaller, the viability of the plants gradually declined, and it was difficult to get summers. The old tubers are perishable or dormant and germinate badly or even without germination, so they are no longer cultivated.
Tissue culture reproduction
Cyclamen rapid propagation of tissue culture can use stamen, tubers, leaves, young stems, etc. as explants, usually collected from a year or two on the young plant, in which tubers as the explants are most likely to induce seedlings. Tissue culture has high technical requirements. When breeding, suitable explants should be collected, collection sites should be collected, and the best medium formulation should be selected. Each step in the rapid propagation process should be performed strictly in accordance with the operating procedures. Strictly prevent diseases. The emergence of seedlings and weak seedlings. Tissue culture propagation is undoubtedly a powerful advantage for the rapid promotion of new varieties that have a good market.
