The growth cycle of Phalaenopsis takes about 3 to 4 years from seedling to flowering in nature.

The growth cycle of Phalaenopsis is long. in nature, it takes about 3-4 years from seedling to flowering. Under good artificial cultivation conditions, prolonging light exposure to 14 hours a day, maintaining night temperature at about 21 ℃, and strengthening water and fertilizer management can shorten the time from seedling to flowering, which takes about 1 to 2 years. Most Phalaenopsis varieties bloom in spring and in summer; pedicels are drawn from leaf axils

There are several flowers, which bloom in turn, each of which can bloom for more than a month. Phalaenopsis is named because the flower is shaped like a butterfly. With beautiful flowers and gorgeous colors, it is a treasure of tropical orchids and has the reputation of "queen of orchid". Phalaenopsis is generally propagated by tissue culture, but it needs certain techniques and conditions, which only professionals can do. How should Phalaenopsis reproduce in family cultivation? The method of changing pots for Phalaenopsis Culture the growth substrate of Phalaenopsis must be well drained

And has a certain water retention performance. The commonly used substrates are moss, fern root, bark, charcoal, ceramsite and so on. The basin change should be carried out in the summer of the growing period. The method is to pour out the plant first, remove the old cultivation substrate, and cut off the aging and rotten air roots. Then put a layer of charcoal on the bottom of the new basin, then put it into the plant, fill in the new substrate, and water it through compaction. The time of changing pot should depend on the cultivation medium. The substrate of water moss will rot in 1 ~ 2 years.

When it decays, it secretes extremely sour substances, which can harm the root of the gas. If it is not replaced in time, it will lead to rotten roots. Therefore, using water moss or bark as substrate, the pot should be changed once in 1 ~ 2 years, once in 2 ~ 3 years with coconut shell and once in 3 ~ 5 years with ceramsite or charcoal. However, fertilizers should be applied frequently and thinly to make up for the nutrients that are not or not contained in these substrates. The method is to first cut off the flowering part of the pedicel, and then carefully remove the bracts between the first and third nodes of the upper part of the pedicel with a blade or sharp blade.

Expose the bud points in the internodes. Apply hormones such as budding agent or indolebutyric acid evenly on the exposed internodes with cotton swabs. After treatment, the orchid plant was placed in a semi-shade place and the temperature was kept at 25-28 ℃. After 2-3 weeks, the buds grew into leaves, and after 3 months, they grew into Phalaenopsis seedlings with 3-4 leaves and aerial roots. Cut off the seedlings and put them on the pot to become a new orchid plant. The principle of stem cutting and reproduction 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. 4. Tissue culture: the excellent genetic characteristics of Phalaenopsis can be obtained by using tissue culture to propagate Phalaenopsis.

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. Temperature is one of the keys to conservation of Phalaenopsis. The suitable temperature for the growth of Phalaenopsis is 18 ℃ 30 ℃, not more than 30 ℃, but in summer, the indoor temperature is often above 30 ℃. At this time, Phalaenopsis can be placed in a ventilated and semi-shaded place.

To help it through the cool summer. The lowest temperature in winter should be kept above 15 ℃, and the temperature should be increased at the turn of autumn, winter and spring, as well as when the winter temperature is low. Appropriate light can promote Phalaenopsis blossom, so that the flowers are gorgeous and lasting, generally should be placed indoors where there is scattered light, do not let direct sunlight. It can be placed in a place where the sun can not shine directly from Nanyang platform from May 1 to National Day, and near the south windowsill during the period from May 1 to May 1 to receive sufficient sunlight. In addition, the normal growth of Phalaenopsis needs flowing fresh air, so domestic Phalaenopsis must be well ventilated.
