Magnolia, also known as Magnolia, belongs to Magnoliaceae Michelia evergreen trees, Magnolia root fleshy, rich in water. The tree is gray-white, sparsely branched, twigs light green, white glossy tomentose. The leaf surface is smooth and glossy, the back is green, and the lateral veins are prominent. Simple leaves alternate, long oval, 15-22 cm long, light green, leathery, glossy. Flowers solitary in axils of leaves, with short pedicels, 12 petals, white. Magnolia began to blossom in late May and is a famous fragrant tree species. It is not only used for ornamental and wearing decoration, but also an important raw material for making scented tea and extracting essence. At the same time, it is also a kind of Chinese herbal medicine, which can carry out turbid qi, relieve cough, treat prostatitis, leucorrhea of women, bronchitis in children, cough caused by fatigue and so on.

The same species of Magnolia are yellow orchid, also known as yellow Burmese cinnamon, orange, sweet-smelling like sweet-scented osmanthus, more fragrant than magnolia! The florescence is later than that of Magnolia. Michelia flowers, smaller than Magnolia, yellow-white, solitary in the axils of leaves, with banana-shaped fragrance. Sweet potato, like light and fear of soot, is not resistant to both moisture and drought. It is suitable for sandy soil which is rich in humus, acidic and well drained. At the same time, it requires plenty of sunshine and good ventilation. Potted Magnolia must be well drained, otherwise its fleshy roots are easy to rot and bloom from May to October. The blooming season is fragrant and pleasing to the eye. Make the white orchid grow strong. Flowers are fragrant and fragrant, and efforts should be made to create conditions in cultivation to meet the requirements of their ecological habits. White orchids like sunshine and are not tolerant to shade, so they require sufficient light. If it is cultivated in a shaded place with insufficient light, it will cause the branches and leaves to grow, the branches to grow and the leaves to be thin, and the flowers will taste light or not blossom.

If cultivated in the northern region, if it is exposed to strong light in hot summer, the plant growth will also be inhibited, and the edge of the tender leaves is easy to appear the symptoms of reversal withering and yellowing. The white orchid is sensitive to water. It likes the air to be moist and the soil moist. When the soil moisture is too much and the permeability is not smooth, there will be rotten roots and yellow leaves, which will lead to the death of fallen leaves. It is appropriate to be rich in humus and acidic sandy loam with good drainage. If it is planted in alkaline or poorly drained soil, its growth will stop or even die.

Northern potted white orchids can choose rotten leaf soil or peat soil, sandy loam soil mixed with the same amount of culture soil, plus a small amount of bone powder as base fertilizer. From the first ten days of May, thin cake fertilizer or alum fertilizer can be applied every 10 days (preferably alternately). Before flowering, 1 Mel was applied twice as quick-acting phosphate fertilizer, which could make the white orchid smell fragrant. Stop fertilizing after the end of September. The amount of watering depends on plant growth and weather conditions. Generally speaking, it is not suitable to water too much in spring in order to keep the basin soil slightly moist.

The temperature in summer is high, the evaporation is fast, and it is in the peak period of flowering, so watering should be sufficient; watering in autumn should be slightly more than that in spring, because the basin is full of roots, less soil and low water storage capacity, but the amount of water should not be more each time. During the growth period, it is necessary to prevent water shortage, otherwise it is easy to cause leaf margin to dry up. As the weather gets cooler at the end of autumn, the frequency of watering should be gradually reduced. In the rainy season, stagnant water in the basin must be removed in time, otherwise it is easy to rot roots and yellow leaves. After each fertilization and watering, the soil should be loosened in time to make the basin soil well ventilated.
