The latest culture methods of Phalaenopsis

Phalaenopsis is a kind of plant suitable for indoor culture, and its flowers are similar to butterflies. Elegant, elegant. It has the reputation of "Lanzhong Queen". Flowers are the most ornamental part of Phalaenopsis. As most of Phalaenopsis are produced in humid Asia, which determines the growth characteristics of Phalaenopsis, ventilation, moderate temperature, high humidity environment is very suitable for breeding Phalaenopsis. Before raising Phalaenopsis, novices should know that stagnant water is not conducive to the growth of Phalaenopsis and avoid exposure to Phalaenopsis in the hot sun. When winter comes, it is necessary to control the indoor temperature. When the temperature is below 15 degrees, it will affect the growth of Phalaenopsis. The following editor will introduce the breeding methods of Phalaenopsis in detail.

Growth habits of Phalaenopsis

Phalaenopsis was born in the tropical rain forest, the nature likes to be warm and afraid of cold. The suitable temperature for growth is 15-20 ℃, and it will stop growing when it is below 10 ℃ in winter, and it is easy to die when it is below 5 ℃. Phalaenopsis, which is native to tropical Malaysia, belongs to the genus Phalaenopsis of Orchidaceae and is a perennial herb. The forest trees along the shores of hot and humid rivers are the places where Phalaenopsis grows.

Phalaenopsis can protect itself from stress in low humidity because of its physiological structure, but in too humid environment, high temperature and high humidity are often accompanied by diseases. The most suitable range of relative humidity is 60%~80%RH.

Propagation methods of Phalaenopsis

The main results are as follows: 1. The method of sowing and reproduction is to sow the seeds from the cracked capsule in the flowerpot of the parent plant. This method is simple and easy, does not need complicated aseptic procedures and operating tools, and is suitable for ordinary family Phalaenopsis growers. However, the chance of success of this method is slim, and it is rarely used. Another method is aseptic sowing, in which the uncracked mature capsule is washed, then soaked in 75% 90% 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.

2. the method of pedicel bud propagation is to cut off the flowering part of the pedicel, and 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 hormones such as budding agents or indolebutyric acid evenly on the exposed Internode nodes with cotton swabs After treatment, the orchid plant was placed in a semi-shade place, and the temperature was kept at 25: 28 ℃. After 2 weeks, the buds grew into leaves, and after 3 months, they grew into Phalaenopsis seedlings with 3 leaves and aerial roots. cut off the seedlings and put them on the pot, they can become a new orchid plant.

3. In the method of broken heart and accelerating sprouting, 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 after a period of time. This feature can be used to breed Phalaenopsis.

4. 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.

5. Tissue culture method, tissue culture method is used to propagate Phalaenopsis, 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.
