Introduction to the breeding methods of Oncidium

Oncidium is a compound-stemmed orchid, and its offspring will grow after growing up, so it is very suitable for propagation by ramet. In addition, Oncidium can also be propagated by tissue culture. The editor will give you a brief introduction to these two breeding methods of Oncidium, which can be understood by friends who like it.

Oncidium

I. split-plant propagation

It can be carried out in both spring and autumn, and it is best to combine with changing pots before new buds germinate in spring. Cut off the false bulb with 2 buds and plant it directly in the basin of water moss to maintain high air humidity and quickly restore new buds and roots.

2. Tissue culture and propagation

The buds germinated at the base of Oncidium were selected as explants, sterilized with 70% alcohol, washed with sterile water, cut into thin slices of stem tips 1-1.5 mm thick, inoculated on the prepared medium, maintained temperature (26 ±2) ℃, light intensity 500 lux, irradiation time 16 hours, on MS medium supplemented with 1 mg / L 6-benzylaminoadenine, the formation of protocorm was the fastest, only 45 days. The protocorms formed continued to be cultured in solid culture medium. After more than 20 days, buds were formed at the tip of the protocorms, and the roots were partially differentiated in the bud base. In about 100 days, the differentiated plants grew 2-3 leaves and became complete seedlings.

Pictures of Oncidium

Oncidium is also known as dancing girl orchid, golden butterfly orchid, tumor petal orchid and so on. Most of the varieties used in commerce are hybrids, the plants are light and slow, the flower stems are light and drooping, and the flowers are strange and lovely, similar to the flying golden butterfly, which is very dynamic, and is one of the most important potted and cut flowers in the world. What exactly does Oncidium look like? What is the fancy language of sending Oncidium? Next, the editor will introduce you one by one.

Hidden love, silent waiting, silent missing

Culture methods of Oncidium

Oncidium prefers moist and semi-shady environment, in addition to watering to increase substrate humidity, leaf surface and ground water spraying is more important, increasing air humidity is more beneficial to the growth of leaves and flower stems. The varieties with hard leaves have strong tolerance to drought, and the phenomenon of dry death has not occurred without watering for a long time in winter, and their tolerance is very strong. Large-scale production requires a sunshade net, with a shading rate of 40% to 50%. Sufficient sunshine is needed in winter, generally without sunshade net, which is beneficial to flowering.

The color of Oncidium flowers is very gorgeous, and many of them are a combination of colors, especially the leopard-print Oncidium, which is particularly beautiful. The petals are dotted with spots like leopard print, which is a cool kind of flower. Enjoy the pictures of Oncidium and see the beauty of Oncidium.

English name: Oncidium

Scientific name: Oncidium

Alias: dance orchid, golden butterfly orchid, tumor petal orchid, dancing girl orchid

Family: Orchid Orchidaceae

Genus: Oncidium Oncidium

Distribution of origin: the original species is native to tropical America, with the largest species distribution in Brazil, the United States, Colombia, Ecuador and Peru. But its distribution area is wide, including tropical zone, warm zone, alpine temperate zone and cold zone.

Morphological features: the shape changes greatly, some species have only 1-2 flowers on a flower stem, and some species can reach hundreds. Oncidium is mainly yellow and brown in color, as well as green, white, red and magenta, etc., some of which are as small as mini-Oncidium, some are very large, and the diameter of flowers can reach more than 12cm.

The culture method of Oncidium-

● growth habits: prefer humid and semi-shady environment, original leaf type (or hard leaf type) prefer warm and hot environment, while thin leaf type (or soft leaf type) and sword leaf type prefer cool climate. Hard-leaf varieties have strong drought tolerance.

● propagation method: the propagation methods of Oncidium include tissue culture and ramet propagation.

● cultivation substrate: Oncidium requires ventilation, ventilation and diuresis. The commonly used substrates are bark, fern root, water moss, charcoal and so on.

● temperature management: slow seedling stage, daytime temperature 25-28 ℃, night 23-25 ℃. The flowering period of Oncidium is relatively short. In order to prolong the flowering period, the temperature can be lowered appropriately. The suitable temperature for the growth of Oncidium is 12-33 ℃, and photosynthesis stops when it is lower than 12. If the low temperature is more than 6-8 hours, the freezing injury will occur, and the growth and development will be hindered when the temperature is higher than 33 ℃.

● humidity management: the relative humidity should be controlled at 60-80%, and the humidity of newly planted seedlings should be about 80%. Should pay special attention to, do not pour a lot of water into the basin to increase humidity, otherwise it is very easy to cause rotten roots, humidity changes should not be too great, otherwise not only not conducive to growth, but also easy to cause bud drop phenomenon.

● water and fertilizer management: the general watering principle is the alternation of dry and wet, each watering should be thoroughly watered, and the next time the substrate should be slightly dry. There is less watering when the plants are just divided in spring, and the plants grow vigorously and evaporate quickly in summer, so they should be watered more. The type and quantity of fertilization are adjusted according to plant growth, generally once fertilizer and one water or two fertilizers and one water.

● pest control: Oncidium common pests are snails, shell insects, whitefly, etc., keep the cultivation environment clean and hygienic, check and remove yellow leaf diseased plants in time to prevent them from becoming a source of infection, spraying pesticides should not leave dead corners, especially the back of leaves, the corners of the greenhouse and the ground should be fully sprayed, and the greenhouse should be disinfected once a month.
