Cultivation environment of Cymbidium chinensis

Lotus orchid belongs to Chinese geophytic orchid, which has strict requirements on ventilation and lighting, lighting and planting sites. The lotus petal orchid likes the wind and fears the evil wind and the cold wind, likes the shade and the cold, likes the morning light and fears the strong sun. Therefore, in order to cultivate lotus petal orchids and cultivate large and strong orchid trees, we must choose a suitable place for cultivation and firmly grasp the needs of wind and sunlight to choose a breeding site.

The northwest wind is often snow wind, which is not only cold but also windy, which is not in line with the growth of orchids. Lotus petal orchid is not only an ornamental plant with long leaves and many flowers, but also a relatively delicate and perennial spring orchid, which can not stand the attack of severe cold, but also can not stand the swaying of strong wind and strong wind. Although the lotus petal orchid is a kind of cold-resistant spring orchid, but the lowest temperature can not be below zero day and night, otherwise frostbite orchid root, orchid seedlings, seriously affect the growth. Therefore, the lotus petal orchid cultivation site must choose the sunny place with a breeze to promote its growth. Family orchid cultivation chooses the location of orchid basin, the balcony and eaves terrace facing east and south is the most ideal.

The cultivation of lotus petal orchid chooses to sit north to south and west to east, so that the orchid bushes can absorb enough light. Sunlight is essential to the growth of orchids. Blue leaves produce nutrients through photosynthesis. Morning sunlight or leaking light is most beneficial to the growth of orchids. The leakage of light is to cover most of the sun with things, and it is the light leaked by the sun from the gap of the obscured object. due to the change of the sun throughout the year, the length and intensity of the light are different, the sun is weak in winter and the climate is cold. direct sunlight in orchid bushes will not be a problem. Spring climate warms up, the sun intensity has increased, lotus petal orchid in the early spring season, can withstand the sun, there is no need to block. In summer and autumn, the sun is long and strong, and lotus orchids can not stand direct exposure. Items such as bamboo curtains must be used to block the sun, which generally covers 70% of the sun and 80% of the sun, resulting in light leakage. At this stage, the lotus petal orchid can only absorb the morning light, and it only takes more than two hours of sunlight to meet its growth needs. In autumn, in addition to shading the noon sun, take the morning sun, and at night also put the orchid pot under the open air to receive dew to promote the growth of autumn buds and spring buds. Care should be taken to avoid the evening sun, otherwise it is easy to burn the orchid leaves.

The cultivation of lotus petal orchid should also pay attention to good ventilation conditions. Orchidaceae plants with aerial roots and ground roots require high humidity, good ventilation and ventilation so that succulent root fungi can normally absorb oxygen to produce nutrients, otherwise it will lead to orchid root rot and necrosis. Ventilation also promotes the metabolism of orchid leaves and regulates the temperature and humidity of the environment. Ventilation in the cultivation of lotus petal orchid is not only beneficial to the growth of orchid leaves, but also essential to the growth of orchid roots. Family orchid cultivation, in addition to the ventilation of the planting environment, but also pay attention to the ventilation between orchid pots, the ventilation between plants in the basin, and so on. To this end, be careful not to put the orchid pot too dense, do not plant too many plants in the pot. At the same time, strengthen the usual management, timely trim and remove the dead foot leaves and orchid leaves, and keep the ventilation between the orchid plants. The orchid plant is airtight, which affects the respiration of the orchid seedling and causes the orchid tree to be not strong, has no resistance, breeds all kinds of diseases, adds pests, and spreads black spot. Therefore, ventilation is also an indispensable means to control diseases and insect pests.

The choice of cultivation site of lotus petal orchid should also pay attention to avoid dust and oil fume. Orchid is an evergreen plant with strong adsorption capacity, which is most afraid of dust and oil fumes. In particular, the lotus petal orchid plant is tall, the leaves are long and wide, the contact area with nature is large, the adsorption capacity is stronger, it is most likely to be infected with dust and oil fume, the stomata of the leaves are filled, and the orchid leaves can not breathe normally, resulting in damage to the orchid leaf tissue, killing the leaf cells, and finally causing the orchid leaves to die. In order to raise the lotus petal orchid well, we should keep the orchid leaves clean and beautiful at any time, remove the leaves from time to time, wash away the dust from the leaves, keep them bright and clean, and keep the stomata open, which is helpful to the growth of orchid plants and increase the beauty of orchid bushes.
