Propagation methods and operation points of Anthurium andraeanum

Because Anthurium andraeanum is a cross-pollinated plant, it is difficult to sow and reproduce Anthurium andraeanum, and the variation is also great. Generally, Anthurium andraeanum uses ramet propagation, cutting propagation and tissue culture. The editor will give you a detailed introduction to the three breeding methods of Anthurium andraeanum. Friends who like Anthurium andraeanum can understand it together.

Anthurium andraeanum (details)

I. split-plant propagation

Anthurium andraeanum has strong tillering ability, which can be combined with inter-seedling, seedling transfer and bud removal of cut flowers to separate the small and medium-sized lateral buds from the mother, and then cultivate the lateral buds into new plants. the specific methods should be carried out in the following aspects:

The main results are as follows: 1. The ramet period is mainly in the cool and humid spring, and it can also be ramified in the cool weather in autumn. Never split in a hot summer or in a dry and cold season.

2. When dividing plants, we should pay attention to the principle of not harming the mother plant, that is, too large lateral buds, too tight lateral buds, and too weak lateral buds, mainly separate lateral buds which are relatively easy to separate from the mother plant and are more robust, with at least two main roots or more.

3. When transplanting seedlings, the lateral buds can be separated from the mother plants by uniform force by hand, and when it is difficult to separate, the lateral buds can be cut open at the bud eyes with a sharp disinfection blade. Cut flowers to remove buds should first be plucked from the soil layer, pay attention to the distribution of the root system and the bud eye of the underground stem, carefully cut the bud eye, and then take out the lateral bud.

4. The cut lateral buds were planted in a cool place after the wound was slightly dried to promote root and restore growth. When planting, the root system should be flattened, the plant should be upright, it should be supported if necessary, it can not be watered immediately after planting, it can be sprayed to the leaf surface to maintain humidity, and watering or thin fertilizer solution can be applied according to the situation after 2 days.

The disadvantages of ramet and cutting propagation are slow growth, difficult disinfection of materials and easy to carry diseases and insect pests (such as root-knot nematodes, bacteria and viruses, etc.). Ramet seedlings and tissue culture seedlings have the same technical requirements, except that the former is taller and stronger than the latter.

2. Sowing and propagation

In Anthurium andraeanum breeding, sowing is the main way to obtain new varieties of Anthurium andraeanum. Anthurium andraeanum fruit is a kind of berry, it must be sowed with picking, peel and pulp should be removed before sowing in order to avoid rot and mildew and affect the germination rate of seeds. Sowing method can use pure sand germination method, sowing seeds in clean river sand, sowing depth of 0.5-0.8 cm, maintain a certain humidity, generally about 15 days can germinate, new leaves will soon grow. When the leaves reach 5 to 6 leaves, they can be transplanted to the substrate of pure perlite mixed with peat soil or coconut bran at 1:2 for pseudo-cultivation.

III. Tissue culture

Tissue culture is a propagation method in which plant materials are cultured in medium and new plants are obtained. the whole process is completed under aseptic conditions in the laboratory. The breeding materials must be strictly sterilized and detoxified in order to provide guarantee for the acquisition of non-toxic clone seedlings.

The propagation materials of Anthurium andraeanum are mainly callus and leaves. The reason for using callus as breeding material is that the cloned seedlings are not easy to mutate, but it is very difficult to obtain non-toxic calli. The leaves are easy to disinfect and easy to operate, but the disadvantage is that the leaves are not smooth, and the plants formed by culture are prone to mutation, but this mutation can be controlled artificially.

In the bottle seedling stage, the tissue culture seedlings completed the growth process under a variety of artificially provided optimal growth conditions. The experimental conditions are very different from the external natural conditions, so it is necessary to let the bottle seedlings go through a transitional process of strengthening and refining seedlings, so that the bottle seedlings can adapt to the external natural conditions smoothly.

Methods and key points of pot cultivation of Anthurium andraeanum

Anthurium andraeanum is a flower plant from South America, and it is also a very common indoor flowering plant. General Anthurium andraeanum can be cultivated by pot or hydroponic culture. What the editor introduces to you today is the method and points for attention of Anthurium andraeanum potted plant. Interested friends can learn about it together.

1. Soil matrix

The soil matrix for planting Anthurium andraeanum must keep good permeability and no stagnant water. When family farming, you can choose to buy prepared culture soil in the horticultural shop and add a mixture of ceramsite and dry bark (ceramsite: dry bark = 2:1) as the substrate. The substrate needs to be disinfected before planting to prevent Anthurium andraeanum from being affected by insect pests in the later stage of growth.

Second, temperature requirements

The most suitable growth environment temperature of Anthurium andraeanum should be controlled between 14 and 35 degrees. In winter, when the temperature is lower than 10 degrees, it is easy to cause red frost damage. Pay attention to keeping the anthurium warm and warming. In summer, when the temperature is higher than 35 degrees, you should humidify Anthurium andraeanum and spray water around it. Do this even if it is high temperature, but if the humidity is high, Anthurium andraeanum is not easy to be hurt.

III. Fertilization

Anthurium andraeanum has a higher demand for magnesium fertilizer than other foliage plants. When family farming fertilizes Anthurium andraeanum, it is recommended to buy Magic Kang fertilizer and apply it together with foliar fertilizer in the horticultural shop. Or fully water-soluble compound fertilizer such as Huaduoduo universal fertilizer is diluted to 800Mel 1000 times liquid fertilizer and applied regularly (not less than once a week). The principle of Anthurium andraeanum fertilization is to apply less thick fertilizer and frequently apply thin fertilizer.

IV. Watering cycle

Water Anthurium andraeanum according to the dryness of the substrate in the basin. If the temperature is high in summer, it is recommended to water once every two days, and spray water to the leaves at noon to increase the relative humidity of the room. In winter, it is recommended to water it once every 7 days. Watering in the cold season should be carried out between 9 am and 4 pm to avoid frostbite to the roots. Generally speaking, water can be watered every 3 days in spring and autumn. Avoid adding water when the plant is seriously short of water, which will affect the growth and development of Anthurium andraeanum. In the process of watering, dry and wet must be carried out alternately, do not water in the case of serious water shortage, this will affect its normal growth and development.

How to raise Anthurium andraeanum, methods of Anthurium andraeanum Culture and points for attention

Anthurium andraeanum is a perennial evergreen herbaceous flower. Sex likes warm, hot, humid and well-drained environment, afraid of drought and strong light exposure. The suitable day temperature and night temperature for its growth are 2632 ℃ and 2132 ℃ respectively. The highest tolerable temperature is 35 ℃ and the bearable low temperature is 14 ℃. The light intensity should be 16000-20000 lx, and the air relative humidity (RH) should be 70%-80%. Usually breeding Anthurium andraeanum does not pay attention to will appear unnecessary trouble, so the following introduces the basic cultivation method of Anthurium andraeanum.

How to raise Anthurium andraeanum (daily culture method) 1. Control room temperature

The optimum temperature for the growth of Anthurium andraeanum is 18 ℃-- 28 ℃. The highest temperature should not exceed 35 ℃ and the lowest temperature is 14 ℃. Freezing injury may occur at any time when it is lower than 10 ℃. In summer, when the temperature is higher than 32 ℃, cooling measures should be taken, such as strengthening ventilation, spraying more water, proper shading and so on. Heating should be carried out in winter if the indoor temperature is lower than 14 ℃.

2. Maintain high air humidity

Anthurium andraeanum growth requires higher air humidity, generally not less than 50%, high temperature and high humidity will be more conducive to the growth of Anthurium andraeanum. When the temperature is below 20 ℃, keep the indoor natural environment; when the temperature is above 28 ℃, spray can be used to increase the relative humidity of leaves and indoor air, so as to create a high temperature and humidity growth environment of Anthurium andraeanum. However, in winter, even when the indoor temperature is high, it is not suitable to cool and moisturize too much, because the plant leaves are too wet at night will reduce the ability of cold resistance, easy to produce freezing damage.

3. Control the light.

When the light is too strong, it may cause discoloration, burns or scorching of the leaves. The success of light management is directly related to the quality of potted flowers and the number of flowers. Anthurium andraeanum is a shade-loving plant, so it is appropriate to put it indoors in a bright place with a certain amount of scattered light, and you should be careful not to put Anthurium andraeanum in an environment with strong direct sunlight.

4. Water and fertilizer management should be appropriate.

Anthurium andraeanum is a kind of flower which is sensitive to salt. The less salt in water, the better. It is best to use tap water. Fertilizers are often applied together with watering. A compound fertilizer with a nitrogen, phosphorus and potassium ratio of 1:1:1 is generally selected. After the compound fertilizer is dissolved in water, it is applied with a liquid fertilizer with a concentration of 1/1000. In spring and autumn, fertilizer and water are generally watered every 3 days. If the temperature is high, the dry and wet substrate in the basin can be irrigated once in 2-3 days; in summer, it can be irrigated once in 2 days; when the temperature is high, it can be watered once; in winter, it can be watered every 5-7 days. Anthurium andraeanum special fertilizer can also be used directly.

5. The matrix should be loose when changing the basin.

It can be mixed with peat soil, leaf bran and perlite at the ratio of 3:2:1.

6. Summer maintenance

In summer, it can be placed on the shady side of the room or in the hall, where there is no direct sunlight outside, in the hall, or outside during the day, under the shade of trees, under flowers or in a cool place. It should be placed on the sunny side of the room in winter, inside the curtains at night, or closer to the heat source.

Matters needing attention in Anthurium andraeanum Culture

1. When buying Anthurium andraeanum, you should choose bright colors, well-developed roots, and only those of good quality.

2. The cultivated soil of Anthurium andraeanum is very important. The fertile soil can permeate some sand and peat soil.

3. Buy ceramic or plastic flowerpots

4. Anthurium andraeanum likes a cool environment and needs to maintain a certain degree of humidity. It should be watered appropriately when the weather is dry, not too often.

5. Proper fertilization and less fertilization in winter

6. After a period of time, there will be some rotten leaves at the bottom, which need to be pruned in time

7. Anthurium likes a shady and wet environment, so it should not be too tight for the breeding soil. Plant a layer of moss on the breeding soil, which is conducive to moisturizing.
