Culture and maintenance methods of Oncidium (Cymbidium and Golden Phalaenopsis)

Oncidium is native to the United States, Mexico, Guyana and Peru. Oncidium, also known as Oncidium, Golden Phalaenopsis, Oncidium and so on, is the general name of Oncidium of Orchidaceae. There are more than 750 native species of Oncidium in the world. Oncidium prefers warm environment, while thin-leaf type (or soft-leaf type) and sword-leaf type. I like cold climate. The optimum temperature for the growth of thick-leaf Oncidium is 18-25 ℃, and the winter temperature is not lower than 12 ℃. The suitable temperature for the growth of thin leaf type is 10: 22 ℃, and the winter temperature is not lower than 8 ℃.

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. With fern root, moss, volcanic ash, bark and other potted or planting bed cultivation. The leaves of thin-leaf species are thin and slightly leathery, and most of the plants grow healthily, which is suitable for planting in medium-temperature greenhouse; thick-leaf species have strong drought tolerance and will not die because of drought when cultivated in greenhouse without watering for dozens of days in winter; sword leaf species have small plant type and are suitable for family cultivation.

Most species of Oncidium are potted, and gravel or broken bricks should be used to cushion the bottom of the flowerpot for about 1/3 to facilitate ventilation and drainage. Cultivated flowerpots can use plastic pots, plain burning pots, porcelain pots and so on. When Oncidium has been cultivated for more than 2 or 3 years, the plant grows gradually and grows into small plants, and the root system is too full, so it is necessary to change the pot in time. Pot change is usually carried out after flowering, non-flowering plants can be chosen before the growth period, such as early spring and autumn when the weather becomes cool, cultivation materials should be changed together, pot change can be combined with ramet. Pay attention to shading in summer and cool down in time when the temperature is too high. In midsummer and autumn, water should be thoroughly watered once a day, that is, until the basin bottom hole comes out of the water. It is better to apply compound chemical fertilizer, thin fertilizer, avoid thick fertilizer, and fertilize in the early morning or after 3 pm. July and August is the flowering period of the plant, which is prone to bacterial soft rot due to high temperature and high humidity, which can lead to plant death in serious cases. For this reason, the plants in the basin can be dried in a sunny day, and the bacteria are not easy to reproduce under dry conditions. At the same time, the rotten leaves and stems will be cut off in time. Before entering the season of high temperature and high humidity, fertilization should be strengthened, especially to increase the proportion of potash fertilizer and cultivate strong seedlings so as to enhance the disease resistance of plants.
