Can Guangdong evergreen be raised by water? how can Guangdong evergreen be hydroponically cultured / 4 successful hydroponics

As a popular foliage plant, Guangdong evergreen has broad leaves and evergreen seasons, and is kept at home by many people. However, in indoor farming, many flower lovers like water farming. They think it looks better this way. Can Guangdong evergreen be raised by water? If so, how can Guangdong evergreen be hydroponically cultivated? In this regard, the editor will introduce it to you in detail.

Can Guangdong evergreen be raised by water?

According to the growth habits of Guangdong evergreen, we know that it likes warm, humid and semi-shady environment, can be stored and transported at 90% relative humidity, and the leaves can survive alone when inserted into the water. Therefore, can Guangdong evergreen be raised by water? Obviously, you can. As for how Guangdong evergreen is hydroponically cultivated, let's move on.

2. How to cultivate Guangdong evergreen in water

In fact, to put it bluntly, the hydroponic culture of Guangdong evergreen is the water insertion method: on the healthy growing Guangdong evergreen plant, choose a healthy branch that is free of diseases and insect pests and insert it into the water. However, before hydroponic culture, florists have to prepare the materials: Guangdong evergreen pot, scissors, transparent glass bottle, water and potassium permanganate.

III. Methods of hydroponic culture of evergreen in Guangdong

1. Time of hydroponic culture

If you want to cultivate Guangdong evergreen in water, you must first choose a good time, preferably in spring and autumn. Because of the high temperature environment in Guangdong, early spring and late autumn can not reach the required temperature for rooting, cuttings are vulnerable to microbial infection and rot in summer, and frostbite in winter.

2. Selection of hydroponic seedlings.

In the method of water culture of evergreen in Guangdong, the most important step is to select water culture seedlings. Methods: on the healthy Guangdong evergreen, the strong branches about 1cm in diameter were cut with sterilized scissors, and the aerial roots on the stem nodes should be preserved.

Treatment of hydroponic seedlings: after the branches are selected, disinfect the cut with potassium permanganate, and then put it in a cool place to dry.

3. Hydroponic culture begins

After making the above preparations, insert the treated water culture seedlings into the prepared transparent glass bottle, and add the right amount of water, which is about 2 to 3 of the container. The control room is about 25 ℃, and the air humidity is kept high. It can take root after 20 days.

4. Hydroponic maintenance

① water exchange

Guangdong ten thousand years green water culture rooting period, breathing is more exuberant, so need plenty of oxygen. To this end, flower friends should change water frequently to keep the water quality clean and meet the oxygen needs of cuttings.

Note: when changing water, the cuttings and containers should be washed clean, especially to strengthen the washing of the cut, after rooting, it can be transferred to normal hydroponic maintenance.

② light / humidity

After the successful hydroponic culture of Guangdong evergreen, we should put the plant under the condition of bright scattered light, the light is too strong, the leaves of Guangdong evergreen turn yellow, and even burn in a large area. In addition, water should be sprayed to the leaf surface frequently to keep the ambient humidity at 80%. If you do not spray water for a long time, the leaf surface will be rough and lose luster.

Cultivation and protection technology of green water in Guangdong I. methods of obtaining hydroponic materials

1. Root washing method: root washing can be carried out all the year round, but the best time is in spring and autumn, so the temperature is suitable, Guangdong evergreen grows vigorously, and potted plants are easy to adapt to hydroponic conditions after root washing.

① chooses Guangdong evergreen with strong growth and soil cultivation (or other substrate cultivation) which has ornamental value.

② removes the plant from the pot and removes the rhizosphere soil.

③ washed the soil in water, cut off part of the old roots, in order to prevent root rot at the initial stage of hydroponic culture, and promote the formation of new roots, 0.5% potassium permanganate could be used for soaking and disinfecting.

④ put the treated Guangdong evergreen plants into a prepared container and injected tap water from no more than two root lines to cultivate new roots.

2. Water insertion is generally carried out in spring and autumn, because the temperature required for rooting can not be reached in late autumn and early spring, and cuttings are easy to rot due to microbial infection in high temperature season in summer. Guangdong evergreen can be watered all the year round. When inserting water, take thick branches, retain the aerial root on the stem node, cut it into small segments about 10cm, disinfect the cut with potassium permanganate (which can be dipped in rooting powder) to dry the juice from the wound, insert it into plain sand or water, keep high air humidity at about 25 ℃, and form a plant material suitable for hydroponic culture in 20 days. During the period of water cuttings healing and rooting, breathing is relatively exuberant, and there must be an adequate supply of oxygen, so the water should be changed frequently at the beginning of the water insertion, in order to keep the water quality clean and meet the oxygen needs of cuttings, and to rinse cuttings and utensils with clean water, especially to strengthen the flushing of the cuttings, which can be transferred to normal hydroponic maintenance after rooting.

3. Ramet method: ramet is usually carried out at the beginning of growth in spring, which reduces the damage to the plant in spring, and enables the split plant to return to normal growth quickly. When the Guangdong evergreen plant is divided, the plant is removed from the basin, most of the basin soil is shaken off, the root system is straightened out, the tiller seedling and root system are exposed, and then the stem of the mother plant is divided into several clumps with a sharp knife according to the necessary size. the wound was disinfected (coated with plant ash or sulfur) and then hydroponically maintained.

II. Key points of water training and protection

1. Change water: Guangdong evergreen must constantly consume oxygen in the water when growing in the water. With the gradual reduction of oxygen in the water of flower growth, when it is reduced to a certain amount, it will have a negative impact on flowers, so whether hydroponic flowers can be successful, the key measure is to change water. Because the oxygen content in the water is inversely proportional to the air temperature (that is, the higher the air temperature and water temperature, the lower the oxygen content in the water; the lower the air temperature and water temperature, the higher the oxygen content in the water) and the different oxygen demand of Guangdong evergreen at different times, the water change interval varies according to the season.

The evergreen grows vigorously in spring and autumn and needs to consume more oxygen, but the oxygen content in the water is also more, so change the water every 7-10 days; in winter, the plant growth is dormant or very slow, consuming less oxygen, but there is plenty of oxygen in the water, so the age interval is long, generally changing the water every 15 days or so. During the high temperature in summer, Guangdong evergreen has a strong respiration, which needs to consume a lot of oxygen while the oxygen content in the water is very little. in addition, the reproduction of microorganisms at high temperature is very rapid, which is easy to make the water quality worse. in order to ensure the normal growth of Guangdong evergreen, it is necessary to strengthen the change of water, which is usually changed once every 4-5 days.

The water for hydroponic cultivation of Guangdong evergreen should be pollution-free and slightly acidic. If tap water is used, it should be connected in advance and placed in the air for more than one day to fully dissolve oxygen and release chlorine. When changing water, wash the mucus from the roots and cut off the rotten roots and scorched leaves.

2. Fertilization: the nourishment of tap water is insufficient for the healthy growth of hydroponic evergreen. Water-raised evergreen chooses a special foliage plant formula nutrient solution, which is applied according to the requirements in the manual. The number of times of adding nutrient solution is more in the spring and autumn when the growth is exuberant. When it is high in summer and slow or at a standstill at low temperature in winter, the number of application is reduced.

In solid substrate cultivation, do not add too much nutrient solution, it is appropriate to submerge the root system in the container, and replenish water on weekdays to maintain the water level. Do not put chemical fertilizer such as urea directly into the water container, because urea is a synthetic organic fertilizer, hydroponic plants not only can not directly absorb the necessary nutrients from urea, but also make some harmful bacteria or other microorganisms get effective carbon sources from urea, and rapid reproduction, causing pollution, and urea will also lead to ammonia poisoning or ammonia ion excess harm. Make Guangdong evergreen poisoned by water.

3. Ventilation: the oxygen content in water is an important factor in the growth of hydroponics, and the oxygen content in water is related to the activities of indoor personnel and ventilation conditions. In the room with poor ventilation and frequent personnel activities, the oxygen content in the water decreases quickly, thus affecting the growth of evergreen in Guangdong, especially during the period of high temperature. therefore, for rooms with water, we should open more doors and windows for ventilation at ordinary times. in order to adjust the room to keep the indoor air fresh.

4. Pest control: diseases and insect pests of evergreen in Guangdong Province rarely occur in hydroponic culture. In summer, strong light should be avoided to prevent sunburn, and lack of light should be avoided in winter to prevent yellow leaves. Anthracnose is rare in hydroponic Guangdong evergreen, resulting in soft rot and dry cracking, which can be prevented and treated with 65% Daimen zinc 600% 800 times or 75% chlorothalonil 800 times. What is the method of cultivating and protecting ten thousand years of green water in Guangdong

A few days ago, my friend asked me what is the training and care method of Guangdong evergreen water. He said that there were all kinds of situations in the Guangdong evergreen he cultivated. He was very worried and did not know how to cultivate Guangdong evergreen. The following editor would like to introduce to you what the training and care method of Guangdong evergreen water is.
