Most of the Cymbidium hybrids require high humidity, so it is necessary to supply sufficient water to the plants throughout the year (the young plants should be appropriately reduced in watering). Generally, water should be poured once a day in the winter and early spring, and water should be poured once before 8 o'clock in the morning and 5 o'clock in the evening from early summer to late autumn, and the foliar water spray growth season should be used once during the watering every day. Cake fertilizer, diluted to 0.02% concentration of liquid fertilizer for 1 time; usually with fermented oily organic fertilizer mixed bone powder or superphosphate to prepare pellets with a diameter of about 2cm placed on the surface of the basin (can be slowly released with the penetration of water) Fertility), and apply a concentration of 0.1% - 0.2% compound fertilizer once a week in combination with watering.
The growth of Cymbidium fuliginea requires sufficient scattered light. In summer and autumn, the shading net is used for about 50% of the sunshade. When the sun is soft in the cloudy or winter and spring, the shading net should be opened to receive direct light. However, in the flowering period, the orchid plant should be placed in a weaker light, so that it blooms brightly.
Propagation by the ramets method. The ramets were longer than the plants after flowering, and the sprouts were not grown before this short dormant period.
Before ramets, it should be properly dried, and the roots should be white and soft when they are soft. Those who grow vigorously usually have a ramets once every 2-3 years, and each cluster of seedlings after cutting should have 2-3 fake bulbs, one of which must be newly formed in the previous year. To avoid wound infection, apply sulfur powder or charcoal powder. Put it in a dry place for 1-2 days and then plant it separately to form a new plant.
After planting, put the semi-shade place, do not immediately water, and find that the dry can spray a small amount of water to the foliage and the pot surface to prevent the leaves from drying out, falling off and the fake bulbs from shrinking seriously. Watering can only be done after the new bud base has produced a new root. Cymbidium can be used as potting substrate for 2 parts of fern root, 1 part of charcoal, or 1.5-2 cm of bark. It can also add some broken bricks, charcoal and other granular materials. Flower pots should be selected from high-density flower pots with a diameter of 15-20 cm, 2-4 seedlings per pot. The high air humidity of the big flower 蕙兰喜, the spring, summer and autumn three seasons, while giving the roots sufficient water, should always spray water.
However, after flowering in early spring, the short dormancy period of Cymbidium hybridum must be watered less, and water can be poured more when new shoots grow larger roots. Large-flowered orchids are large and growing, and require more fertilizer than usual, so fertilization should be strengthened during the growing season. Generally, the fermented cake fertilizer and the like may be mixed with 1/3 of the clay, and water is added to make a ball having a diameter of about 2 cm, and dried for use. When watering, it should reach a pouring or diarrhea, there is no water in the basin or the water seepage is too slow.
Household pots should not be too large. It is better to use pots with a diameter of about 25 cm. Each pot has 3 to 4 mature orchids. After 2 years, it can be increased to 8-9 strains. The pot still has 3 to 4 strains. Propagation of the old pseudo-phosphorus stems under the basin. If you want to cultivate larger orchids, you can use a basin with a diameter of 30 cm or more. The drainage layer must be designed, at least 1/3 of the basin depth. This is The key to the success of the cultivation of Cymbidium.
In the spring, it is placed on the surface of the pot and there is a certain distance from the sprout. The fertilizer can slowly release nutrients for orchid growth. It can be applied twice a year, several grains per pot, or fermented liquid farmyard fertilizer. Once every 1-2 weeks, spray the NPK fertilizer to the leaves and pots, the concentration should be 3-5%. 1-2 times a week. Stop the fertilizer at the end of autumn.
Guaranteed illumination: Cymbidium is native to low-altitude and high-altitude areas. The growth temperature is 10°C to 25°C. It is not suitable for winter and moderately at 10°C. The large flower eucalyptus is light, except for the high temperature season in summer, it can accept direct light. It should be shaded by about 30% at high temperature to promote the formation of flowers and prevent sunburning leaves.
Watering and moisturizing: The flowering orchid has higher requirements on moisture, and it should not be dried during the growth. In principle, it is dry and poured, and the pouring must be poured. The spring, autumn and winter seasons can be poured once every three or four days, and the number of watering should be gradually increased as the temperature rises. Watering should be done 2 to 3 times a day in summer, and often spray the surface water to increase the humidity of the air to avoid yellow leaves.
Reasonable fertilization: During the growth period, it should be applied with thin fertilizer and can be applied with thin chemical fertilizer or compound fertilizer. If more bone powder is applied, the fermented bean cake fertilizer can make the flowers bigger and more. The liquid fertilizer should be diluted 1:1000, once every 10 days. Fertilizer should be applied before flowering, and no fertilizer should be applied during flowering and summer season.
