Culture methods of Cymbidium

Cymbidium is a terrestrial herb of Orchidaceae, born in a wet but well-drained light-transparent place. Let's take a look.

Cymbidium is distributed in China, Nepal, northern India and other places. The root is thicker and shorter, the base is slightly thicker than the front end of the root, and there are no branches. The pseudobulb is inconspicuous, clustered and oval in shape. Flowers are often yellowish green with deep purplish red veins and spots; flowers are usually rich in fragrance. One stem has many flowers, often 6-12, fragrant.

Huilan is native to China and is one of the oldest and most popular orchids in China. In ancient times, it is often called "Hui". "Hui" refers to the central "Huixin" of Chinese orchids, and is often named "Huizhi" with Angelica dahurica. Cymbidium is a rare species in China and a national second-class key protected wild species. Cymbidium was originally distributed in the south of Qinling, north of Nanling and southwest, and is one of the more hardy orchid varieties.

Growth habits of Cymbidium

(1) the number of leaves: Cymbidium, also known as Cymbidium, Cymbidium, Xialan, the number of leaves per plant is 5-9, often 6-7, leaves about 25-80 cm long, about 1 cm wide, erect.

(2) the new leaf buds of Cymbidium are unearthed from early May to early June, and the autumn buds are unearthed from late July to mid-August. There is a slow period of about 20 days after the new leaf buds are unearthed, the leaf spreading period is from mid-June to late July, the leaf extension period is from July to October, and the dormancy period is from November to February of next year. It is very important to cultivate Cymbidium with more than 3 seedlings, but it is not easy to survive with less than 3 seedlings, which is very important. It takes about 3 years for each seedling to grow and complete.

(3) the flower buds of Cymbidium are unearthed between September and early October every year, and stop growing after growing about 2-3 cm. It takes about 5 months (temperature 5 degrees Celsius) for vernalization and dormancy to produce fragrant and pleasant flowers. The flowering period is from late March to late April every year. Late flowering in early May.

(4) the suitable temperature for the growth of Cymbidium is 15-25 ℃, no more than 38 ℃ in summer, 5 ℃ below zero in winter and 10-20 ℃ in winter. Huilan is the most cold-tolerant and high-temperature-tolerant orchid in Guolan.

(5) the requirement for air humidity of Cymbidium is 60%, 75%, not less than 50% during winter dormancy, and 70%, 80% during growing period.

(6) Water requirements of Cymbidium: its false bulb is small and needs to keep the basin soil moist, but it is the most drought-tolerant orchid in the national orchid. It has thick and long roots, has certain water retention, and can cope with short-term drought (4 days). Therefore, root preservation is the top priority of planting Cymbidium. We must understand the meaning of "not dry in autumn, not wet in winter". Early autumn sunny, hot, dry air, increase air humidity is the most effective way to prevent the coke tip of orchid leaves.

(7) Light requirements of Cymbidium: light is very important to the growth of Cymbidium. Cymbidium is the most light-loving orchid. It needs about 60% shade when the sun is strongest in summer, but it can not be shaded in other seasons.

(8) Cymbidium needs to be cultivated in a deep pot, and its roots are generally unbifurcated. Cymbidium should be selected with slender roots, tight shells, colorful bracts, and leaf sheaths such as needles. Its flowers are generally 5-12, a few can reach 18. Cymbidium from Jiangsu and Zhejiang is the best. There are more new products in Henan, Hubei and Shaanxi.

(9) Cymbidium likes light to be afraid of darkness, ventilation to be afraid of blockage, looseness to be afraid of hardening, clumps to be afraid of individual points, and thin, fat and thick heat.

Culture methods of Cymbidium

Cymbidium is usually propagated by plant division. The ramet time is longer than that after flowering and before the new bud grows, this short dormancy period takes place. It should be properly dried before ramet and operated when the roots are slightly whitish and soft. Those with strong growth usually split once in 2-3 years, and each clump of orchid seedlings should have 2-3 pseudobulbs, one of which must be newly formed in the previous year. To avoid wound infection, you can apply sulfur powder or carbon powder. Put it in a dry place for 1-2 days and then plant it separately, that is, it will become a new plant. After planting, it should not be watered immediately. It is found that if it is too dry, a small amount of water can be sprayed to the leaf surface and basin surface to prevent the leaf from drying up, falling off and the false bulb from shrinking seriously. Wait for the new bud base to produce new roots before watering.

Cymbidium likes strong light. Cymbidium is native to tropical and subtropical plateaus of Asia, and likes cool and humid environment. The suitable temperature for growth is 10-25 ℃. It should be kept in a low-temperature greenhouse in winter. It grows well when it is about 10 ℃ at night. The flower stem elongates normally and blossoms in February-March. When the winter temperature is lower than 5 ℃, the leaf is slightly yellow, the florescence is delayed, and the flower stem is short. However, when the overwintering temperature was about 15 ℃, the leaves were green and shiny, and the flowering was advanced to January-February to supply the Spring Festival market. Very like wet, but should pay attention to ventilation, otherwise easy to get anthracnose, seedling humidity should be 80% to 90%, medium and large seedlings should be 60% to 85%. The flower diameter is soft and must be supported by a pillar to keep it upright.

Fertilization: the ratio of nitrogen, phosphorus and potassium in the growing period was 1:1:1, the ratio in the flowering stage was 1:2:2 to 3, and the pH value of the fertilizer solution was 5.86.2. Generally speaking, the fertilization concentration is 3500 to 4000 times for small seedlings, 2000 to 3500 times for medium and large seedlings, 1 to 2 times per day in summer (alternating application of water and fertilizer), and fertilizer is usually applied once every three days in other seasons. Organic fertilizer: organic fertilizer should be applied once a month from the bottle of tissue culture seedlings to before flowering, the ratio of bean cake to bone meal in the growing period is 2:1, and pure bone powder should be applied in the florescence. Organic fertilizer cannot be applied to the root. If the salt content of bone meal is too high, it can be washed with water first and then applied. You'd better stop applying organic fertilizer in winter.

Watering: sprinkler irrigation is usually used in production, once a day in May and September, twice a day from July to August, and every 2 to 3 days from October to April of the following year. The watering times should be adjusted at any time according to the size of seedlings and weather conditions.
