How to cultivate and maintain cyclamen by hydroponics?

Cyclamen, alias rabbit ear flower, rabbit flower, a crown, radish begonia. Belong to cyclamen genus of Primulaceae. Cyclamen plant height 15-40cm, with flat round fleshy tubers. The leaves grow at the tip of the tuber, with long stalks, subcordate, green with silvery markings and blunt teeth of different sizes. The flower is drawn from the axilla of the leaf, how large, with a fleshy long pedicel (15-25cm); sepals 5-lobed, petals 5, base connected into a short tube, on the reverse roll twisted, such as rabbit ear-shaped, hence the name "rabbit ear flower". The plant type is more like a fairy stepping on the clouds, elegant incomparable, so it is also known as "cyclamen". Flowers and colors are rich, there are white, red (bright red, purple, orange red, pink), purple and mixed colors, etc., some have fragrance. The florescence lasts as long as 5 months. It is a precious potted flower in winter and spring.

1. Hydroponic method

The main results are as follows: (1) before resuming growth after dormancy of cyclamen in late August, corms with more than 10 leaves, more than 3cm, no disease and insect pests and healthy growth were dug up and washed for hydroponic culture.

(2) generally, bulbs above 3cm should choose containers with diameter and above 15cm. The corms to be transplanting were anchored in the planting cup with foam, ceramsite, water moss or vermiculite, and the first and third parts of the corms were exposed, the growing points could not be buried, and the roots were immersed in the nutrient solution. From soil culture or substrate culture to hydroponic culture, it is appropriate to slow down the seedlings for one week. See the light in the morning and evening one week later, and the whole day after one month. The suitable height of nutrient solution is 1pm 2 which submerged the root system.

(3) the garden test nutrient solution was selected, and the concentration was about 1 to 2 of the standard concentration, and the pH6~7,.25- was changed once every 30 days.

2. Maintenance guidelines

The main results are as follows: (1) the temperature and light suitable for cyclamen growth is 10-20 ℃. If the temperature is higher than 30 ℃, the plants will go into dormancy, and if the temperature exceeds 35 ℃, the roots will rot. The safe overwintering temperature in winter is 10 ℃, and freezing injury will occur if the flower is lower than 10 ℃. Cyclamen likes to scatter enough light and avoid direct sunlight.

(2) watering when the indoor air is too dry, it is easy to make cyclamen buds dry and black, at the same time, the leaves will gradually turn yellow, and the florescence will be obviously shortened, so water should often be sprayed to the leaves to increase air humidity.

(3) Fertilizer and hydroponic cyclamen should be added when changing water, and fresh water should be used after flowering.

(4) at the beginning of water culture, put the plant in the dark and change the water every 5 days. After 1 week, new roots can grow at the bottom of the corm, which can be moved to a place with plenty of light for maintenance. When the water rooting reached more than 5cm, it was maintained with hydroponic nutrient solution. The hydroponic cyclamen is shown in the picture.

(5) pest control of hydroponic cyclamen is prone to soft rot and aphids. In the high temperature season from July to August, if the ventilation is poor, soft rot is easy to occur, which should be prevented in time. Can prune thick old leaves and withered leaves; if aphid disease is found, kill it in time, and observe whether there is recurrence at any time. [Jishan Huayao]
