What kind of soil is used to cultivate Phalaenopsis?

Phalaenopsis, also known as Phalaenopsis, Phalaenopsis, etc., is an epiphytic plant of Orchidaceae. The plant pulls out long pedicels from leaf axils and blossoms like butterflies, which are favored by flower fans. Known as the "queen of foreign orchids", they are of high ornamental value. Let's take a look at what kind of soil Phalaenopsis is cultivated.

What kind of soil is used to cultivate Phalaenopsis?

Phalaenopsis is an aerial plant, and its potted plant material should not use soil, but should use water moss, pumice, Alsophila dust, broken charcoal, etc., or directly fix the seedlings on the corrugated board (snake wood) and let it attach and grow on its own. this cultivation method is modelled on its original ecological environment. During cultivation, materials such as pine needles, peanut shells, bark silk and clay balls can be selected as the substrate for breeding Phalaenopsis, which requires high soil permeability, decay resistance, micro-acid and water permeability. if you can not configure these materials, you can buy Phalaenopsis special orchid soil directly to the flower market.

What pot is used to grow Phalaenopsis?

Phalaenopsis should choose bamboo utensils, porous ceramic pots or special orchid pots, it is best not to use general plastic pots, planted seedlings should not be shelved on the ground, should be hung or placed on the shelf, in order to facilitate the elongation and growth of air roots, to facilitate the absorption of air nutrients after drying, to avoid rotting roots or even death caused by stagnant water in bottom holes or underground pests to harm plants in the basin. Considering that Phalaenopsis likes the breathable growth environment, it is recommended to choose the porous shallow basin, the basin height is less than the basin diameter is the best.

Propagation methods of Phalaenopsis

1. Natural sowing method: natural sowing method is to sow seeds from cracked capsules in flowerpots of parent plants. This method is simple and easy, does not need complicated aseptic procedures and operating tools, and is suitable for ordinary family Phalaenopsis growers. However, this method has little chance of success and is rarely used.

2. Aseptic sowing: in aseptic sowing, the uncracked mature capsule is washed, then soaked in 75% ethanol or chloroform for 2 seconds, and then soaked in 5% 10% bleach solution or 3% hydrogen peroxide for 5 minutes for 20 minutes. Take out the seeds and soak them in the same disinfectant for 5 minutes, then remove the solution by filtration, take out the seeds, and spread the seeds evenly on the surface of the culture medium in the prepared bottle with fine needles. The culture conditions were as follows: light intensity 2000-3000 lux, 10-18 hours a day, and the temperature was kept at 20-26 ℃. After 9-10 months, the seedlings can grow 2-3 leaves and then be planted in pots.

3. Pedicel budding method: pedicel budding method is to first cut off the flowering part of the pedicel, then carefully cut off the bracts of the first to third internodes in the upper part of the pedicel with a blade or sharp blade to expose the bud points in the internodes, smear the budding agents or hormones such as indolebutyric acid evenly on the exposed Internode nodes with cotton swabs, and place the orchid plants in a semi-shaded place after treatment, keeping the temperature at 25 ℃. After 3 weeks, the buds grow into leaves, and after 3 months, they grow into Phalaenopsis seedlings with 3 or 4 leaves and aerial roots. cut off the seedlings and put them on the pot to become a new orchid plant.

4. broken heart method: after the growth point of the orchid plant is destroyed due to some factors, 1 or 2 new buds will grow from the stem node near the base of the orchid plant over a period of time, which can be used to propagate Phalaenopsis.

5. Stem-cutting reproduction method: the principle of stem-cutting reproduction method is to destroy the growth point of stem tip to induce latent bud growth. Although there are 1-3 latent buds in the axils of Phalaenopsis plants, most of them can not sprout into plants. After the plant continues to grow upward and the stem node is longer, the upper part of the plant with roots is cut off with sterilized knives or scissors, implanted into a new basin to make it continue to grow, the lower part of the rhizome is given proper water management, and new buds can sprout soon.

6. tissue culture method: Phalaenopsis can be propagated by tissue culture method, which can obtain the same excellent genetic characteristics as the mother plant. The butterfly orchid seedlings produced by this method are called meristem or tissue seedlings. The plant tissues (explants) used for meristematic culture can be terminal buds (stem tips), stem segments (dormant buds), young leaves or root tips, but at present the most common is the pedicel of Phalaenopsis.
