[can hanging orchids be raised in water] can hanging orchids be raised in water

Can orchids be kept in water? Cymbidium, also known as potted grass, belongs to the perennial evergreen plant of Liliaceae. Culture of Cymbidium can be divided into two methods, namely, hydroponic culture and soil culture. Hanging orchid has a very strong function of absorbing toxic gases, can purify carbon monoxide, carbon dioxide, formaldehyde and other toxic gases, so it is also known as "green purifier", is a good indoor air purification flowers. Cymbidium can grow roots suitable for aquatic environment under the conditions of high temperature and high humidity, and it is one of the good species of domestic water-raised flowers. Common varieties are green broad-leaf orchids, silver-edged orchids, Phnom Penh orchids and golden orchids, etc., these varieties are very suitable for water culture, and there are a variety of forms of water culture.

Can orchids be raised in water?

Sure

Aquaculture method

1. Passenger equipment

Any container that can hold water can be used to raise orchids, it is best to use transparent utensils to raise them, and you can enjoy the dazzling white roots in the water. The glass cups, teacups and mineral water bottles around you are both economical and beautiful containers.

The containers of water-raised orchids can be single-layer or double-layer. The single-layer container is made of glass bottles and plastic bottles without bottom holes and planted directly on the hanging orchid. The double-layer container takes the plastic screen (also known as the planting basket) as the upper layer, and the lower layer is the non-porous bottle. The hanging orchid is planted in the upper plastic screen and the root of the hanging orchid extends into the lower bottle.

2. The steps of aquaculture of Cymbidium

(1) remove the graceful potted orchid from the pot and wash the soil.

(2) cut the old root. Cut off the withered and yellow leaves.

(3) insert it into the plastic screen and fill it with blue stone or Maifan stone to increase the permeability and fix the plant. Then put it in a wide-mouth transparent glass bottle and keep it in water.

3. Aquaculture of individual plants

The small Cymbidium with aerial root on the creeping stem was cut from the mother plant and raised in water.

Maintenance and management

(1) when raising the orchid in water, just let the root system of the bottom 1 hand 3 touch the surface of the water, and don't put all the white fleshy roots of the orchid into the water, otherwise the water will cause the root to rot.

(2) the hanging orchid that has just been put into the water is changed once a day, and the frequency of changing water is reduced after taking root.

Daily Management of Water Culture of Cymbidium

① water: when raising Cymbidium in water, just let the root system of bottom 1DUP 3 touch the surface of the water, do not put all the white fleshy root of Cymbidium into the water, otherwise it will cause water to rot.

Just put into the water to raise the hanging orchid to change the water once a day, after taking root to reduce the number of water change. In single-layer container bottle cultivation, water and flower nutrient solution are added every 4 days, and the water is input from the straw until the water is full. Change the water of the double-layer bottle once a week, pour out the water when changing the water, wash the bottle clean, fill it with water and flower nutrient solution, and then put the plastic sieve on the bottle. Ammonia nitrate and potassium dihydrogen phosphate can also be added to the water, including nitrogen, phosphorus and potassium fertilizer, which can promote the growth of Cymbidium. The proportion is 3/1000, and a small amount of penicillin is added to prevent the occurrence of bacteria, and the water is changed once every 10-15 days.

If the root system of Cymbidium has rotted in water, it is best to clean the bottle and the root system of Cymbidium, cut off all the rotten root system, and soak and disinfect it with 500-fold solution of potassium permanganate for 20 minutes. Put the disinfected orchid in a cool place first, and then re-cultivate it with clean water for about 2 days. The environment should be semi-overcast or scattered light, and it will gradually weaken in the shade. It needs to be kept in a sunny place in winter. If the temperature is 20-25 ℃, you need to change the water every 3 days. When the temperature is lower than 20 ℃, it is best to change the water every 5 days or so. When the temperature is higher than 25 ℃, you need to change the water once every 1-2 days. And in each change of water, flush the mucus on the roots with tap water, so that the management can ensure that it will grow well. Pay attention to do not apply fertilizer within 1 month, you can apply less in the future, which is conducive to recovery.

② fertilizer: adding water and changing water in the root and adding flower nutrient solution at the same time, topdressing outside the root is spraying branches and leaves with diluted flower nutrient solution every 3 days.

③ control of diseases and insect pests: if you find any diseases and insect pests, you can use universal powder and water to spray leaves.

④ to promote flowers: half a year after the flowering, do not spray water on the flowers, to prevent early falling flowers, flowers withered should be cut off from the branches to promote re-flowering.
