The culture method of monkey face small dragon orchid

Monkey-faced small dragon orchid, also known as monkey-faced orchid, is a small epiphytic plant of Orchidaceae, with strange and large flowers and rich colors, which are mostly used for potted, hanging pots or hanging blue cultivation. It is very suitable for the green decoration in front of the window of the bedroom, the wall of the balcony, the window of the commercial building, the entrance of the exhibition hall and so on. Let's take a look at the breeding method of monkey-faced dragon orchid.

The growth habits of Monkey-faced Cymbidium

Monkey-faced small dragon orchid requires a cool growth environment, afraid of extreme heat, difficult to spend the summer, and is not resistant to frost and cold. 10-25 ℃ is the suitable cultivation temperature. The warmer areas in the south can be placed in outdoor semi-shade or cultivated in plastic greenhouses throughout the year. The Yangtze River valley or the north should be cultivated in greenhouses with medium or high temperatures. In late autumn, winter and early spring, the temperature is not very high. Direct sunlight is given to facilitate the plant to form flower buds, blossom and bear fruit. If you encounter high temperature weather or in summer, you should increase the humidity and cover the sunshade net to cool down. The temperature below 10 ℃ should be kept warm and heated.

The Propagation method of Monkey-faced Cymbidium

1. Ramet: the ramet of Monkey face is generally carried out before the new buds germinate in early spring, first take out the mother plant from the flowerpot, remove the excess matrix, separate the knotted root system as far as possible, and cut it open from the base of the stem with a sharp knife. Each new plant should keep two or more plants, with a certain root system, and use a brush dipped in sulfur powder or carbendazim powder to smear the wound to prevent the wound from infecting bacteria. After ramet, the new plant can blossom in the same year.

2. Sowing: monkey-faced Magnolia can self-pollinate, but the seeds are easy to scatter and should be harvested in batches at the right time. Because the seeds of monkey face orchid are small, they are usually sown in autumn in greenhouse, and the seedlings are raised with flat or hole trays, and the seeds do not need to be covered with soil. They should be fully exposed to light after sowing, and the seedlings will generally emerge in about 25 days. Do not water too frequently at the seedling stage, just keep the substrate moist. At the same time, fungicides were sprayed once a week, 2-3 true leaves should be transplanted once, and planted in flowerpots when the seedling height was more than 10 cm, and the seeded seedlings could blossom for 1-2 years.

The culture method of monkey face small dragon orchid

1. Matrix: monkey face small dragon orchid prefers acidic matrix, which requires loose air permeability and good drainage, which can keep the root moist without stagnant water. Generally, the substrate can be used for orchid cultivation. When the seedlings are installed in a basin, first put a coarse-grained matrix or ceramsite with a thickness of 2cm in thickness at the bottom of the basin as a filter layer, sprinkle some Ordovician granule controlled-release fertilizer as base fertilizer, apply 2g in each pot, and cover a substrate about 1cm in thickness, then put in the plant to separate the fertilizer from the root system and avoid root burning.

2. Moisture: the original environment of monkey face is relatively dry, and it is easy to be infected by bacteria if it is too long in cloudy and rainy days. Therefore, the relative humidity should be kept between 50 and 75% during the growing period. When the temperature is about 20 ℃, you can keep the natural environment indoors. When the summer temperature is more than 25 ℃, artificial humidification is carried out, generally using fan and water curtain or high-pressure spray system, but avoid spraying water on the leaf surface. There should be more ventilation when the humidity is too high, otherwise diseases and insect pests are easy to occur. The moisture needed by monkey face orchid generally depends on the substrate used. If water plants are used, water should be watered less, and when the substrate is 70% dry, water should be watered in time.

3. Fertilizer: monkey-faced Magnolia needs less fertilizer, and its general fertilizer concentration is 3000 times of liquid. It should be fertilized every two weeks in the growing season from May to October. Liquid fertilizer should be used to irrigate the root zone and spray the leaf surface. The growing period of monkey face orchid is mainly nitrogen fertilizer and balanced fertilizer, often using N:P:K=30:10:10 or 20:20:20 mixed fertilizer. The mixed fertilizer of N:P:K=10:30:10 is commonly used during flowering. It is best to apply fertilizer in the evening and water again in the early morning. At the same time, in the flower bud stage, special orchid flowering fertilizer, Huabao 3, potassium dihydrogen phosphate and other phosphorus and potassium fertilizer were sprayed once a week to make the arrows stronger and the flowers bright.

Pest control of monkey-faced small dragon orchid

1. Aphids: often endanger young leaves and buds in groups, sucking juice with nymphs and adults. A small amount can be brushed off with a brush to treat spraying 1000 times of aphid lice wettable powder, or 2.5% deltamethrin EC 2000 × 3000 times, or 40% methomyl 1000 times or chloramidine 1500 times, etc.

2. Scale insects: adults and nymphs absorb juice on petiole, leaf base and leaf surface to produce macula. Scale insects are easy to breed in a poorly ventilated environment. Make sure you are well ventilated. In the event of the occurrence of scale insects, 1000 times of 25% buprofezin wettable powder or 800 ~ 1000 times of 40% EC should be sprayed in time, once every 7 days for 2 or 3 times in a row.

3. Snails and slugs: they often nibble on new buds, leaves, buds and roots at night. From June to October, timely prevention and control should be carried out in humid environment. If you sprinkle lime powder on the ground, you can also spread it where it is infested with 8% Miaoling granules, or spray pesticides such as trichlorfon on the leaves.

Disease control of monkey-faced small dragon orchid

1. Wilt disease: it often occurs in the season of high temperature and humidity, especially after summer rain. The leaves of the plant turned yellow and wilted, and the whole leaves rotted. Cut off the dead and diseased leaves and pay attention to the plant material not to be too wet. Choose 2000 times solution of carbendazim or 2000 times solution of propiconazole emulsion to spray base or root irrigation. Or spray 50% carbendazim wettable powder 1000 times, or 40% thiophanate methyl suspension 2000 times, or 2.5% Xerox suspension 2000 times, once every 7 to 10 days for 2 times in a row.

2. Anthrax: it often occurs in the rainy season. In the early stage of the disease, round and oval reddish-brown plaques appeared on the leaves, and in the later stage, the plaques turned dark brown, and in severe cases, there was gangrene. Cut off the dead leaves and pay attention to ventilation. Can be sprayed with chlorothalonil, methyl thiophanate, mancozeb and other wettable powder 600-1000 times, once every 5-7 days, twice in a row. Before or at the initial stage of the disease, 50% anthrax Ling EC can be sprayed 600 times, once every 10 days, continuous prevention for 3 or 4 times.

3. White silk disease mostly occurs in the high temperature and rainy season from August to September. In the early stage, the base of the orchid leaves turned brown and rotted, producing white silk mycelium, and in severe cases, the whole leaf clump withered and died. The greenhouse should be ventilated and the distance between pots and flowers should not be too close. At the time of onset, you can use 800-1000 times liquid for blue disease treatment, or 1000 times for 50% Fudoning, or 2000 times for 2000 times, once a week for 3 times in a row. The roots of the seedlings can also be watered with 1% copper sulfate, and the infected potted flowers should be cleared out of the greenhouse and buried.

4. Leaf blight: it often occurs in the case of high temperature and high humidity, and small black spots are produced near the leaf tip or at the front of the leaf, and the disease spot gradually expands into the whole leaf, and finally wither and fall. When symptoms were found, the diseased leaves were removed immediately, and 800 times of chlorothalonil or 500 times of mancozeb were sprayed at the same time.

5. Tillering rot mainly occurs on tillering buds, followed by leaves. In the early stage, the base of the bud showed a disease spot the size of mung bean, and it was easy to infect the leaf surface when it was hot and humid, resulting in dark brown water-stained patches. On continuous rainy days in summer, it is easy to occur if the fertilizer and water are not managed properly, and the basin soil is highly humid and heavy. Soil water content should be controlled. When the new buds are 4-5 cm high, spraying 1000 times of 0.01% boric acid solution or Shikujing can also be prevented by 1000 times of agricultural streptomycin.

6. Root rot: some or all of the roots rot and blacken, and the plant grows poorly. The main causes are blockage of drainage hole at the bottom of the basin, poor ventilation of matrix waterlogging, excessive watering, cold weather or heavy fertilizer injury. Dredge the drainage hole, do not pour the head water during the growing period of the new seedling, and ventilate in time after spraying water on the leaf surface to keep the leaf base dry. Avoid excessive nitrogen fertilizer during the growing period, and irrigate the roots with 50% Ganfuling wettable powder 1000-1500 times or 15% carbendazim water 600 times 800 times, once every 7-10 days, 3 times 4 times in a row.
