Diagram of ramet propagation of Anthurium andraeanum

At present, China's potted Anthurium andraeanum seedlings are mainly imported from the Netherlands, such as Anzu Company and Ryan Company are famous Dutch Anthurium andraeanum seedlings production suppliers. There are four kinds of common potted materials of Anthurium andraeanum: tissue culture seedlings, cutting plants, pot seedlings and pot seedlings. A basic principle: the smaller the plant, the more difficult it is to cultivate. Tissue culture plantlets and cutting plants need special planting methods, which are difficult and generally not recommended.

For growers, if the cultivation conditions are better and have some experience, you can choose potted seedlings with a plant height of 10-15 cm. This kind of seedlings can be planted directly in the last pot, which is safer. When you have enough experience, you can choose a pot seedling with a height of 6-10 cm, which is cheaper to transport. The following is a diagram of the ramet of Anthurium andraeanum:

First, the best time for ramet

1. The best time: the ramet period of Anthurium andraeanum is mainly carried out in the cool and humid spring, and it can also be divided in the cool weather in autumn. It is not suitable for ramets in hot summer or dry and cold seasons. If there is greenhouse equipment, it can be carried out all the year round.

2. The best leaf age: the daughter plant grows slowly after the seed plant is too small, and the daughter plant is too large, which affects the growth of the mother plant. In general, ramet can be carried out when the daughter plant has 4-5 leaves, which is very beneficial to the growth of both the daughter plant and the mother plant.

2. Preparation before plant division

1. Matrix preparation: Anthurium andraeanum likes the matrix with loose and good air permeability. Peat and perlite can be mixed in the ratio of 2 ∶ 1, and carbendazim or methyl topiramate can be sprayed, stirred and stacked evenly for 1 day. At the same time, a soft plastic basin with a diameter of 9cm or 12cm is prepared for cleaning and disinfection.

2, flowerpot preparation: different stages have different specifications for pots, the seedling stage has generally been completed in the seedling company, and the Anthurium seedlings purchased during production are more than medium seedlings (about 15 cm). Therefore, when planting in the pot, you can choose the red plastic pot of 160 × 150mm for one-time use.

3. Mother plant selection: generally speaking, small and medium-sized varieties of Anthurium andraeanum have stronger tillering ability and produce more lateral buds than large varieties, which is suitable for split propagation. In order to ensure that the mother plant has sufficient nutrients for growth and flowering, lateral buds need to be removed and ramet propagation should be carried out. The mother plant for ramet should grow healthily and be free from diseases and insect pests.

III. Operation and management

The main results are as follows: 1. Hand-breaking ion plants: when transplanting seedlings, the lateral buds and mother plants can be broken away from the underground stem buds evenly and forcefully.

2. Cut the ion plant with a knife: when it is difficult to separate, use a sharp disinfection blade to cut it at the bud hole. Cut flowers to remove bud ramet must first pluck away 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.

3. Disinfection of split seedlings: the sub-plants were graded according to plant size, and then disinfected after classification. The roots were washed once with clean water, and then soaked in 100-fold solution of acylpeptides for 15 minutes for 30 minutes. Take out and dry the water on the root system.

4. split seedlings on the pot: when potting, close the two daughters of the same size into a pot, so that the root system is flat, the plant is erect, and can be used as support if necessary. The substrate should not be too much when potting, and the ramet seedlings after potting should be sprayed with carbendazim to wash the leaves, disinfect and sterilize, and pour through the substrate with pure water one day later.

Note:

The main results are as follows: 1. In order not to affect the growth of other Anthurium andraeanum in the greenhouse, a sunshade net can be set up above its seedling bed to ensure its weak light.

2. The relative humidity should be kept at 75% Mur85%. If the humidity is too low, you can spray on the leaf surface, especially in summer ramets, you should pay more attention to increase the number of foliar spray.

3. Keep the temperature between 25 ℃-28 ℃, the matrix should not be overwatered, just keep it moist.

4. generally, new roots can grow after 20 days and turn to the normal growth stage. at this time, the light can be gradually enhanced, fertilizer and water can be applied, and unified management with tissue culture seedlings of the same size.

5. Because there are relatively many diseases and insect pests in ramet seedlings, more attention should be paid to the prevention and control of diseases and insect pests than tissue culture seedlings.
