How to cultivate Cymbidium officinale

Orchid is a perennial "aerial" or "epiphytic" herb of Orchid, also known as air orchid. Some species can reach 2 meters in diameter, and the smallest is less than 10 cm. This is a peculiar flower. It doesn't need soil or clear water to grow. As long as it exists in the air, it can rely on the scales on leaves to absorb water and nutrients in the air to maintain its life. At the same time, the leaf forest can reflect sunlight and reduce water evaporation. It can be seen that its growth mode is quite strange, just like ordinary ornamental plants, and it will produce brightly colored flowers, and often a small new plant will grow on the inside of the lower leaf base and continue to reproduce. Dictyophora pubescens will mature in one to several years, which also depends on the variety and growth environment. Different varieties of cymbidium have different flowering periods. Generally, the flowering period is May-165438+1October, and flowers also have different shapes. The common colors are pink, pink and purple, and most of them are bright and dazzling. Some varieties will produce peanuts-sized pineapples after flowering, and the capsules will split automatically after maturity, and the seeds with feathered crowns will be scattered all over the floor. Cymbidium hybridum is drought-resistant and strong light-resistant, and grows well in warm and humid places with sufficient sunlight and ventilation. The demand for sunlight varies from species to species. Varieties with hard and gray leaves need sufficient sunlight or strong scattered light, and varieties with green leaves have low requirements for light and can grow normally in semi-shade or indoors. The optimum growth temperature is 65438 05℃ to 25℃. Ventilation should be strengthened when the temperature is higher than 30℃, but most varieties below 5℃ will be frozen and plants below 0℃ will die. During the growing period, plants should be sprayed with water frequently to increase the air humidity, and the spraying time is better at night or before the sun rises in the morning. Don't spray water in the hot sun. When spraying water, spray it until the leaves are all wet. Don't let water accumulate in the center of plants, so as not to cause "rotten heart" If the air humidity is above 90%, it can grow without caring at all. In the case of long-term water shortage, plants will shrink, leaves will roll up and the tip will dry up. If this happens, you can soak the plants in clear water for a period of time, and then take them out after absorbing enough water, and the residual water on the plants will be shaken off. Potted plants should avoid being in wet media, not to mention stagnant water, so as to keep dry. Although broccoli can grow without fertilization, it grows slowly and flowers are scarce. In order to make it grow healthily, spray flower fertilizer every 20 to 30 days during the growing period, and stop spraying in winter and flowering period. Cymbidium hybridum, like other bromeliads, should not be planted on calcareous plants, so it should not be attached to substances with high calcium content such as corals and stalactites.
