Cymbidium hybridus, also known as tigerhead orchid and cymbidium, is a perennial evergreen grass plant of orchidaceae. Its varieties are numerous, with large petal, colorful and colorful flowers, red, yellow, green, white, pink, purple and various transitional colors and composite colors. The stems are erect and firm, and the flowering period is longer. They can be potted or used as fresh cut flowers. , deeply loved by consumers, has become one of the most widely cultivated foreign orchids in the world. First, the reproductive technology Cymbidium commonly used ramets breeding, every 2 - 3 years for 1 time. The specific method is to take out the vigorously growing plants from the pots, cut them off from the junction of the pseudo-bulbs with a knife, and cut them into several bundles. Each bundle should have 2 - 3 false bulbs (one of them must be the former Newly formed.) Apply incisions with sulphur powder or charcoal powder in a timely manner. Place the new plants in a dry place and dry them for 1-2 days. It is advisable that the time of the ramets is changed from flower to stalk to sprouting. Candidates can use sterile sowing, fertilized embryo culture, tissue culture and other methods for large-scale breeding. Second, the upper basin points should be in the early spring sprout before transplanting pots. Choose a deep and transparent pan. According to the different needs of different species, the cleaned sphagnum moss, bark, charcoal blocks, stones, broken bricks, peat, etc., are dubbed as different cultivation (humidity) cultivation soils, the pH value of which is 5.5--6.0. between. When planting, pay attention to the false bulbs must be exposed on the surface of the culture soil. After planting, put it in the semi-yin and semi-yang position. Since the cultivation soil is moist when planting, so avoid watering within 1 week after planting. Spray only on leaf surface (usually spray 4-6 times per day) after 1 week. Gradually transferred to normal maintenance. Third, maintenance and management points 1. Watering: Most Cymbidium species need higher humidity, so all seasons need to be sufficient water supply to adult plants (young plants should be appropriately reduced water). Generally, water should be poured once every morning in the winter and early spring. Before 18:00 in the early summer and in the late autumn, water should be poured once every day and after 5 o'clock in the evening, and water spray should be performed once a day (fog). 2. Fertilization: During the growing season, the cooked cake fat is diluted with 0.02% liquid fertilizer and applied 1--2 times. Usually, the fermented oil-based organic fertilizer is mixed with bone meal or superphosphate to make a pellet with a diameter of about 2cm. The surface (can release the fertility slowly with the infiltration of water), and apply the compound fertilizer with concentration of 0.1%--0.2% once a week with watering. 3. Illumination: The growth of Cymbidium grandiflorum needs sufficient scattered light, and in summer and autumn, shading nets are used to shade about 50%. When the sun is sunny or winter and spring is soft, the shading nets must be opened to accept direct light. However, in the flowering period, the blue plant should be placed in a place where the light is weak, so that it can bloom and bloom. 4. Temperature: Most varieties of Cymbidium hybrida prefer a cold climate, generally thriving at 15-25°C, and the maximum temperature that can be tolerated in summer is 35°C. In the fall, when the temperature is above 25°C, flower buds will stop growing and turn yellow and wither. Annual young seedlings should be wintered above 5°C. 5. Pest control: 1 prone to white spot disease in poor ventilation conditions, can be used 12% copper fructose EC 600--800 times liquid spray and irrigation, after 7--10 days, and then sprinkle irrigation. 2 Black spot disease and blue head blackness sometimes occur. It can be sprayed with 70% thiophanate 1000 times solution or 50% carbendazim 1000 times solution and sprayed once every other month to prevent its occurrence. 3 scale insects can be diluted 600--800 times sprayed with wind oil. 4 Starscream, can use neutral detergent to spray water 150 times; 5 maggots, can be used Pulsatilla root 500g boiled for half an hour, after filtration, liquid spray.
