Culture method of hydroponic Anthurium andraeanum

Anthurium andraeanum, also known as candle, Anzu flower, red crane flower, red taro, red goose palm, etc., originated in Costa Rica, Colombia and other tropical rain forest areas, has great ornamental value, sexual preference for warm, humid, semi-shady environment, very suitable for hydroponic culture. Let's take a look at the breeding methods and matters needing attention of hydroponic Anthurium andraeanum.

Can Anthurium andraeanum be cultured in water?

Anthurium andraeanum can be cultured in water. Anthurium andraeanum likes warm, moist and semi-shaded environment, which is very suitable for hydroponics. Anthurium andraeanum should pay attention to moisturizing, not only to change water for Anthurium andraeanum, but also to spray water to the indoor of Anthurium andraeanum, so that the leaves can keep enough water. More importantly, spray water to Anthurium andraeanum leaves. Moisture is the key to red palm blooming and graceful posture.

Culture method of hydroponic Anthurium andraeanum

1. The transplantation of Anthurium andraeanum: dig the potted Anthurium andraeanum from the soil, cut off the rotten roots, hairy roots and old leaves, wash the roots with clean water, disinfect them in potassium permanganate solution, and then wash Anthurium andraeanum with clean water. If you hydroponically cultivate Anthurium andraeanum with transparent glassware, it is best to cover the glass with a black plastic bag to prevent strong light. Cover it with a transparent convenient bag (heat preservation and moisturizing). Put it in a place where the light is scattered and the temperature is kept above 10 degrees.

1. Nutrient solution configuration: it is recommended to choose foliage plant nutrient solution, which must be replaced every 7-10 days. Regularly changing the water of Anthurium andraeanum can remove the mucus and some algae secreted from the roots of Anthurium andraeanum. When the temperature is high in summer, it is more frequent to change water than in winter. It is recommended to change the water of Anthurium andraeanum every 2-3 days. The water should not be too full to prevent Anthurium andraeanum from rotting. It is best to keep about half of the roots of Anthurium andraeanum out of the water. It can ensure that the root system absorbs oxygen.

2. Light and temperature: Anthurium andraeanum likes semi-shade, warm and humid environment is also one of the requirements of Anthurium andraeanum growth environment. If you are afraid of sun exposure, you should pay special attention to the location in the process of breeding, preferably in a place where it is ventilated and can avoid strong light. In summer, hydroponic Anthurium andraeanum should pay attention to the temperature of the surrounding environment should not be higher than 28 degrees. The relative air humidity should be maintained at 80%, and sprinkle some water on the leaves of Anthurium andraeanum when the weather is dry. The temperature of Anthurium andraeanum cultured in water in winter can not be lower than 14 degrees. When the temperature is lower than this temperature, Anthurium andraeanum is prone to frost injury. Be careful to keep it warm and warm. And control the air humidity at about 80%, and must not put Anthurium andraeanum outdoors, otherwise it is easy to cause anthurium frostbite.

3. Reasonable oxygenation: the difficult problem faced by hydroponic Anthurium andraeanum is that it will cause rotten roots of Anthurium andraeanum if there is less dissolved oxygen in the water, so it is necessary to increase the oxygen content in the water in time during hydroponic culture. The easiest way is to vibrate, fix the flower plant with one hand, and gently shake the vessel with the other hand for more than 10 times. After shaking, the dissolved oxygen content of the nutrient solution can be increased by about 30%. Or add 1% hydrogen peroxide (3% hydrogen peroxide) to the nutrient solution, and if possible, a miniature submersible pump or aeration pump can be used to add oxygen to the nutrient solution.

4. Selective rooting: when cultivating Anthurium andraeanum in hydroponics, part of the native roots can be removed, slightly rooting, and heavy rooting can be done if you want to enhance the aquatic adaptability of the root system.

5. timely change of water: the root breathing of Anthurium andraeanum is very strong, so change the water regularly, remove the mucus and some algae secreted from the roots of Anthurium andraeanum, and cut off the old and rotten roots. This also helps to increase the amount of dissolved oxygen in the water, generally 2 or 3 days to change the water, winter can be changed once a week, each time to add a nutrient solution. In the hydroponic culture of Anthurium andraeanum, as long as the roots of Anthurium andraeanum are immersed in water, and the other roots are exposed to the air, so that the roots of Anthurium andraeanum can breathe. Insufficient dissolved oxygen in water can lead to rotten roots of Anthurium andraeanum.

Matters needing attention of hydroponic Anthurium andraeanum

1. Hydroponic Anthurium andraeanum leaves yellowing: it is necessary to disinfect Anthurium andraeanum. It is recommended to buy hydroponic training solution to the flower market to promote rooting. It is safe to grow flowers with it after dilution. The water temperature should be close to room temperature, not directly with tap water. The yellowed leaves should be trimmed off. Generally speaking, flowers will have yellow leaves. It is OK to trim them. When the flowers have new leaves, it is very healthy.

2. How to fertilize hydroponic Anthurium andraeanum: it is best to choose special liquid fertilizer for Anthurium andraeanum, because Anthurium andraeanum has a large demand for magnesium, so the general compound fertilizer is not only alkaline, but also has less magnesium content! After each change of water, drop 1-3 drops into the water, depending on the size of the container.

3. Hydroponic Anthurium andraeanum root rot blackening: hydroponic Anthurium andraeanum should be placed in a bright place in front of the window with diffuse light, unlike soil flowers, hydroponic flowers should not have direct light to illuminate their roots, otherwise they will inhibit the roots or cause photooxidation injury of the roots, resulting in blackening of the roots and loss of activity due to severe decay. You need to cut off the rotten roots and let them all soak in the nutrient solution.

4. Hydroponic Anthurium andraeanum control humidity: high temperature and high humidity are beneficial to the growth of Anthurium andraeanum. When the indoor temperature is higher than 28 degrees, the relative humidity of the air needs to be increased. At this time, tools such as air humidifiers can be used to increase the humidity of the air.
