Hydroponic culture methods and matters needing attention of Cymbidium

Although the magnolia is more afraid of dampness, the hydroponic magnolia can be successful, and many friends will watch the flowers above in the container of hydroponic magnolia, watch the roots below and enjoy the fish in the water. So how should the family raise magnolia hydroponics?

Gentleman orchid

First, from soil cultivation to hydroponic culture

Rinse the biennial potted orchids with clean water, cut off the old roots and yellow leaves, and culture them in clear water for 1-2 days; the water temperature requires about 15 ℃, and at the beginning, it is appropriate to only make the depth of the roots to 1, 3, 1, 2; gradually increase the amount to all the roots immersed in water, but if water droplets are found at the leaf tips, the water level should be lowered immediately.

II. Disinfection and prevention of plants

In the initial culture or each time for water change, container change, pruning, root pruning, etc., clean utensils can be used to hold 0. 1% potassium permanganate solution, by means of the gap between each operation of the plant, soaked in the solution for 5 minutes, then rinsed with clean water, and planted in a container, can play the role of disinfection and prevention of diseases and insect pests.

Nutrient solution for soilless cultivation

It is composed of more than 10 kinds of major and trace elements, such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and so on. There are many formulations of elements and their contents. Ordinary families can use a small amount of potted magnolia fertilizer or buy a special hydroponic flower nutrient solution from the florist.

4. Use water and nutrient solution

Place it in a place with bright light and air flow. In daily maintenance management, the general summer season can be changed every other day or even once a day, and put into a small piece of charcoal antiseptic, winter every 10 rain 15 days to change, with the ph value of water is appropriate to maintain 6.0 rain 7.0; regular application of a small amount of 2m 3 drops of nutrient solution, not only to add the nutrient solution in the water, but also with the nutrient solution (the nutrient solution can be made by yourself or purchased in the florist) to spray leaves to make it thrive.

Methods and matters needing attention of hydroponic culture of Cymbidium

Cymbidium is a common indoor flower potted plant, from ancient times to the present, there are too many people who like to cultivate Cymbidium. In addition to soil culture, Cymbidium can also be cultured in water. The following introduces the matters of water culture and the operation steps of water culture. I hope that the flower friends who cultivate Cymbidium can be useful.

Methods and items of hydroponic culture of Magnolia 1. Selection of hydroponic containers

In order to carry out hydroponic culture of Cymbidium, we should first choose a good container. Generally speaking, it is better to use a transparent glass container. If you raise a seedling, you only need a glass can. If you want to plant a lot of water, you can use fine wire to compile a metal mesh with a diameter of one centimeter, and make a glass hydroponic box slightly smaller than the metal mesh, or you can use a goldfish tank instead. Then the metal net was covered on the hydroponic box, and the seedlings of Cymbidium were inserted into the nutrient solution through the mesh, and the depth of the flower root in the culture medium did not exceed the limit of the false bulb of the root.

2. Preparation of nutrient solution

Nutrient solution is divided into inorganic and organic. The inorganic nutrient solution can be prepared according to the following proportion: 1.5g of calcium, 0.01g of ferrous sulfate, 1g of urea, 1g of potassium dihydrogen phosphate and 0.5g of magnesium sulfate. After the above five inorganic salts are mixed together, they can be dissolved in 1000 grams of water. The organic culture solution was prepared as follows: fried flax seed flour 100g, bone powder (made of salt-free fresh bone) 100g, bean cake powder 150g, cooked sesame powder 50g, and then dissolved in 1000 grams of water. Compared with the above two kinds of nutrient solution, the composition of organic fertilizer is rich, but the nutrient content is not high, and the composition of inorganic fertilizer is relatively simple, but the fertilizer effect is high and the effect is fast. In order to learn from each other's strong points to offset their weaknesses, the two can be used together. If used alone, inorganic fertilizer is applied once a week, and organic fertilizer is applied once every 5 days.

3. Water for hydroponic culture of Cymbidium

In hydroponic cultivation, tap water cannot be directly used, but "trapped" water must be used. the so-called "trapped" water is to put tap water in a container and bask in the sun for 3 to 5 days to precipitate chlorides such as bleach that are harmful to the roots of magnolia. The "trapped" water, from the outside, the sediment changes from strips to lumps, and the color of the water is green. After "trapping" good water, the position of the submerged root must not submerge the false bulb. If the water level is too shallow, the magnolia can not get sufficient water supply, and if the water level is too deep (flooding the false bulb), it will cause root fester. In the process of breeding, we should pay more attention to observe the changes of water quality, and find that some roots turn yellow or black, indicating that the water is both anoxic and less fertile, and the water must be changed immediately.

3. The course of hydroponics of Cymbidium

A, choose a 2-3-year-old gentleman orchid, and wash the roots, soak in potassium permanganate solution for 10 minutes, then rinse with clean water, raise with tap water no more than 1/5 of the root system, and change the water once every three days.

B, notice that there are rotten roots, need to trim rotten roots, old roots, 10-15 days pseudo-bulb base can germinate new roots, add water to no more than 1/2 to 1/3 of the root system, new roots grow to about 5 cm, and cultivated with nutrient solution.

C. after flowering, the residual flowers need to be cut and sprayed with potassium dihydrogen phosphate solution, which can enrich the plant development and promote the differentiation of flower buds.

4. Air, sunshine, temperature

Whether we can deal with the ventilation of hydroponic orchid root is the key to the success or failure of hydroponic culture. It is found that after anoxia in the water, oxygen must be replenished. There are two methods: one is to change the water, and the other is to supply oxygen to the water with a small oxygen pump. In the treatment of sunlight, Magnolia is a half-yin and half-yang plant, we should pay attention to the light, especially in summer, to avoid the strong direct sunlight, so that it can receive scattered light. In addition, according to the light-oriented characteristics of Cymbidium leaves, we should pay attention to make the leaves receive light evenly, otherwise the leaf length will be different, the growth direction will be scattered back and forth, and the illumination angle should be adjusted every two or three days. In terms of temperature treatment, the ambient temperature of adult Cymbidium should be 11: 25 ℃, and the seedlings can be slightly higher, 20: 35 ℃. The temperature difference between day and night should be mastered in orchid cultivation in water, which should be kept at about 20 ℃ during the day and not less than 15 ℃ at night in winter.

Culture methods and matters needing attention of hydroponic Cymbidium how to hydroponically cultivate Cymbidium

At present, most families still adopt the method of soil culture. After seeing other green plants in water culture, they will wonder whether our orchids can be cultivated in water. Cymbidium is a popular flower from ancient times to the present. It is placed in a glass container with a panoramic view through the appearance of the clear water. Today, wed114 Marriage Network Xiaobian brings you the breeding methods and matters needing attention of hydroponic magnolia, and teaches you how to hydroponically cultivate magnolia.

The function of water cultivation of Junzi orchid

The magnolia itself has ornamental value, and its appearance has been greatly improved after hydroponics. The so-called side look at a line, such as open a fan, cold winter months when a piece of ice and snow, hydroponic magnolia is in full bloom indoors, a school of vitality.

Container selection

The key factor of hydroponic culture is the container, the suitable container is not only beautiful, but also conducive to plant growth. Generally speaking, transparent glass containers are the best for easy observation of underwater conditions. But if it is to raise a seedling, as long as a glass bottle can (Xiaobian also at home water culture gentleman orchid, go directly to the supermarket to buy a bottle of yogurt, want that kind of glass bottle, yogurt can be used after drinking disinfection, super convenient.) If the plant is a little larger, you can use a fish tank instead.

Water requirement

Hydroponic magnolia can not directly use tap water, must use "trapped" water, that is, put tap water or bask in the sun for 2-3 days, so that harmful bleach in tap water and other chlorine volatilization, reduce the damage to the roots. "trapped" water, from the surface, there is a mass of sediment at the bottom of the water, the water will be light green.

When hydroponic culture, do not submerge the false bulb when the submerged root reaches the position, pay attention to the depth of the water. If the water level is too shallow, the gentleman orchid can not get enough water, and the water level is too deep, which is easy to cause rotten roots. In the process of maintenance, pay attention to observe the water quality, find that the root turns black and yellow, and change the water immediately.

Light and air

Gentleman orchid is suitable for growing in half-yin and half-yang environment, pay attention to light when hydroponics, especially in summer, avoid direct sunlight and receive scattered light. In order to let the leaves receive light evenly, rotate the flowerpot regularly.

The growth of all things needs sufficient oxygen, so there should be sufficient oxygen in hydroponics. You can raise a few small fish in the container, if the small fish swim freely, it means that there is no lack of oxygen in the water; if the small fish always float to the surface to breathe, it means that the water is lack of oxygen and needs to be replenished with oxygen.

Specific steps of hydroponic cultivation of Magnolia

First of all, choose a healthy and disease-free orchid, soak in potassium permanganate solution for 10 minutes, and then rinse with clean water. Try not to hurt the root, and use scissors to get rid of the old root.

Then it was cultured in clean water which had been left in air for 2 days, and the water temperature was kept between 15 ℃ and 20 min.

At the beginning, it is appropriate to make the water entry depth of the root system at 1 beat 3-1 beat 2; gradually increase the amount until the root system is completely immersed in water, but if water droplets are found on the leaf tip, the water level should be lowered immediately. Change the water every three days or so.

The base of the false bulb for 10-15 days can germinate new roots, adding water to 1/2 to 1/3 of the root system, and the new roots grow to about 5 cm, indicating that hydroponic culture is successful. After that, it can be cultivated with nutrient solution.

Common problems and treatment methods of Shuipei Junzi Orchid

Rotten root

The most important feature of hydroponic plants is that you can see white roots, at the same time, the roots are also prone to diseases. So when hydroponic magnolia has rotten roots, how to remedy it.

The magnolia should be taken out first and the root system should be dried. Soak in diluted chlorothalonil solution for a few hours, then cut off the rotten roots and put them back into a container replaced with new water and nutrient solution. After leaving it in a cool and ventilated place for a week, it can basically recover.

Long macula

Green leaf plants are most afraid of withered and yellow leaves, while hydroponic magnolia has macula, which may be the following situations.

1. Lack of light, gentleman orchid likes the sun, but should be careful not to be exposed to strong light

two。 The water level is too high, hindering the root growth, the root should be properly raised, the water level can be soaked to the root 3/4.

3. If the nutrient solution is too much / too little, the nutrient solution can not be added in winter and can be added appropriately in spring and autumn.
