The big head orchid is also the red of the red of the Zhuding that we often say, the friend that raised big head orchid is infatuated with for its, for its infatuate with. However, how to breed large headed orchid? What's the best way to breed? Please read on with me with questions!
The breeding methods of two bright turquoise orchids (basic knowledge): the best breeding time: Turquoise orchids mainly propagate in separate balls, and the best breeding time is from February to march in spring.
The best growing soil: the best growing soil should be sandy loam rich in humus and well drained.
Requirements for growth humidity: the soil should be kept moist and watered thoroughly. Generally, the humidity should be maintained in the indoor air humidity.
The best growth temperature: big head orchid likes warm and humid climate, the growth temperature is 18 ℃ ~ 25 ℃, avoid extreme heat, the sun should not be too strong, in summer should be placed under the shade for maintenance. In winter dormancy period, cold and cool climate is required, 10 ℃ ~ 12 ℃ is suitable, not lower than 5 ℃.
The best growing light: big head orchid likes sunshine, which can be direct sunlight, but not too long. It should be placed in front of the window with bright light, good ventilation and no direct light.
Precautions for cultivation of large head orchid in the yard: apply fertilizer: large head orchid likes fertilizer. During the growth period, apply fertilizer once a half month along with the growth of leaves. Stop applying fertilizer in the flowering period, and continue to apply fertilizer after flowering. Mainly apply phosphorus and potassium fertilizer, reduce nitrogen fertilizer, and stop applying fertilizer at the end of autumn. Some superphosphate can be added to potted plants as base fertilizer.
Key points of watering: keep the plant moist and water thoroughly. But avoid excessive water and poor drainage.
Pruning tips:
1. Big head orchid's pruning requirements are not strict. Generally, you can prune it according to your favorite shape.
2. The growth of large headed orchid is fast, and the leaves are long and dense. It is necessary to cut off the dead leaves, withered roots, and the roots and leaves of diseases and insect pests at the same time of basin changing and soil changing, leaving vigorous leaves.
Basin soil replacement: after 1-2 years, the basin soil for cultivating large Turquoise orchid is lack of fertilizer. In order to promote the growth and flowering in the new year, new soil should be replaced.
Key points of propagation: the propagation of Bighead orchid mainly includes the method of dividing bulb, dividing bulb, sowing or tissue culture. The following mainly introduces the method of dividing bulb and sowing propagation.
1. Ball splitting propagation: Ball splitting propagation shall be carried out from March to April. The ball around the mother ball shall be removed and planted separately. The soil cover shall not be too much when planting, and the top of the small bulb shall be slightly exposed to the soil surface. In this way, it needs to be cultivated for 2 years before flowering.
2. Sowing and propagation: when the seeds are mature, they can be sown and germinate quickly at 18 ℃ ~ 20 ℃; when transplanting the seedlings, pay attention to prevent the root injury. After the second transplanting, they can be put into a small basin. In the winter of that year, they must overwinter in a cold bed or a low-temperature greenhouse. In the spring of the next year, they can be planted in a pot and bloom in the third year.
Disease and insect control: the main diseases of Bighead orchid include virus disease, spot disease and nematode disease.
1. Spots damage leaves, flowers, scapes and bulbs, and round or spindle red brown spots occur, especially in autumn. The diseased leaves should be removed, the bulbs should be soaked with 0.5% formalin solution for 2 hours before planting, and the same amount of Bordeaux solution should be sprayed regularly in spring.
2. The virus disease causes the red root and leaf of cinnabar to rot. 75% chlorothalonil wettable powder can be sprayed 700 times.
3. The nematode mainly invades from the stomata of leaves and flower stems, and causes the disease of leaves and stem flowers after invasion, and gradually spreads to the direction of bulb. The bulb should be soaked in 43 ℃ warm water and 0.5% formalin for 3-4 hours to achieve the control effect.
4. Red spider is harmful to insects. It can be sprayed with 40% dicofol emulsifiable concentrate 1000 times.
Pot culture and soil culture of large headed orchid: large headed orchid is a beautiful ornamental plant, which is mostly planted in soil and rarely cultured in water. For example, when hydroponics is carried out, it is half immersed in the water. When flowering, the snow-white roots and green leaves set off the bright flowers, which are particularly elegant and beautiful. The hydroponics method is as follows:
Select the seed ball: generally select the large headed orchid (bulb is more than 6cm), cut off all leaves before the frost after autumn, and control water to promote its dormancy (dormancy period is not less than 25 days or 50 days before the Spring Festival, and it is difficult to see flowers before the festival later), then soak the bulb with 1 / 1000 depth of permanganate solution, remove the old roots and impurities, and then plant it in Narcissus basin (put clean coarse sand particles Or a pebble to hold the ball in place.
Hydroponics conditions: if glassware is used as wall hanging, no sand or stone can be placed. Just submerge a half of the seed ball in the water. Put it in the place where there is no sunlight, and keep the ambient temperature between 20 ℃ and 25 ℃. Change water every 2-3 days in the first half of the month, and then every 4-5 days.
Daily maintenance: in order to make the flowers bloom better, you may as well add a little inorganic fertilizer to the newly changed water every week after the scape is exposed to make it a very thin inorganic liquid fertilizer. When the scape grows to about 3 cm, the ambient temperature is raised to about 25 ℃. When the flower bud is about to open, the plant should be placed in a cool place with an ambient temperature of about 10 ℃, so as to make the red flower of Zhuding more colorful and have a longer flowering period. When it's warm after flowering, plant the watery red to the underground for maintenance, and the growth is still vigorous. In winter, if we cultivate them in this way, they will bloom again in Spring Festival.
Large head orchid stamen
The experience of breeding large headed orchid:
All the friends who have raised large headed orchids are fond of their big and colorful flowers, which bloom in early spring. On the other hand, if the management is not good, it is often distressed because the flower arrow is difficult to stand and bloom in the leaves. Do you have such experience? Let's learn how to get rid of this kind of trouble.
1. It is necessary to let the red cress have sufficient light. After it grows new leaves, it is necessary to apply fertilizer mainly composed of phosphorus and potassium once a week, such as dry cake, bone meal, and fish offal. Less or no application of nitrogen fertilizer to avoid excessive growth of leaves and affect flower bud differentiation and flowering. Until the arrow is drawn out, the fertilization can be stopped, otherwise the phenomenon of falling flowers and buds ahead of time is easy to occur.
2. During the growth and flowering period of red cress, the basin soil should be kept moist to ensure the water demand during flowering and growth. When the flower arrow is long, the flower is large and many, in order to prevent it from leaning and falling, a pillar should be set up to protect it. After the flower withers, it should be cut off from the base of the flower arrow in time to avoid nutrient consumption in the plant, so as to facilitate the sprouting of new flower arrow.
