Orchids are like golden millet, and their fragrance is like orchids. In recent years, planting Milan has gradually expanded from the Yangtze River basin, covering urban and rural areas in the north and south. Milan is an evergreen shrub or small arbor flower of Meliaceae, which is also known as Meliaceae, Eupatorium, Eupatorium and Ylang. Usually, the plant height is about 1 m, the maximum height is 4 to 5 meters, and the branches are dense. Odd pinnate compound leaves alternate, with 3 to 7 leaflets, smooth and waxy. Bulb rhizome, axillary, slightly scattered, small flowers golden yellow like millet, fragrant like blue. Berries are oval to round and bloom most in summer and autumn. Milan also has a local nickname "Jin Si Shui", but it should not be confused with Jin Si Shui's "Jin Si Shui".

Milan ornamental cultivation of large tree species, leaves, plant height more than 5 meters, planted in the open field in South China, only 1 flower a year, also known as Magnolia. There are also races with dense branches and small leaves, plump and beautiful plants, which grow and develop under moderate environmental conditions and bloom continuously all the year round, also known as Milan in the Four Seasons, and are often used as potted flowers everywhere.

Milan, a subtropical tree species, is produced in Fujian, Guangdong, Sichuan, Yunnan and Southeast Asia. Sex likes mild and humid climate, tolerates semi-shade, and likes sunshine in high-humidity and cloudy areas in the south. Planting in the north avoids the hot summer sun, and the weather is dry and windy. It is advisable to shade in high temperature season (above 25℃). When the temperature is lower than 25℃, it should be fully illuminated. Milan is not cold-tolerant, and the wintering temperature should not be lower than 10℃. It requires loose, fertile and slightly acidic loam or sandy loam rich in humus, and avoids salinity. The soil in the West Basin and its surrounding environment are always moist. Drought and dehydration are easy to cause yellow leaves or green leaves to cause plant death.

Milan can receive wild seeds in the natural environment, usually by layering and cutting propagation. High pressure method is commonly used in South China. From late April to mid-May, plants with strong growth and no pests and diseases were selected, and 2-year-old to 3-year-old branches were selected on the sunny side, and the cambium was exposed at the position 20 cm away from the bifurcation. The width of the incision is about 2 cm. After the incision is slightly dry for a day or two, it is wrapped with mud strips and then wrapped with film to keep the mud strips moist all the time and take root in about 50 days. In the second stage, after the new roots are sent out, the mother plants are cut off, followed by mud sticks to slow down the seedlings in the shade, and planted in pots after 1 month.

In recent years, Milan has been cutted and propagated in the northern part of China by using the method of keeping moisture with film buttons. In May, 65,438+0-2-year-old branches were taken as cuttings, which were about 65,438+00 cm long and had 2-3 compound leaves for cutting. Mix peat soil and sandy soil evenly as cutting substrate, and cover the plastic film with sunshade net. The rooting rate can reach about 60% before and after beginning of autumn. However, after transplantation, it slowly grows and takes shape in the north, with twice the result with half the effort.

The introduction of ground planting or potted seedlings requires strong plants, complete roots and tight packaging in order to survive planting. In the south, dry pond mud is used to break it, and then potted seedlings are planted. Come to the north for a year and need to change the soil. Peat, rotten leaves and sandy soil are planted in the north. Families can use (old) Clivia soil and plain sand to cultivate soil. The basin should not be too big, and alkaline fertilizer should not be added to the soil. The bottom of the basin should be padded with drainage layer. After planting, put the seedlings in the shade for maintenance. When the weather is dry, spray water on the leaves and the surrounding ground every day to keep the environment moist. After the new leaves grow, they will move to the shade, and then gradually adapt to the strong light, and the flowers will be more fragrant. Potted flower seedlings in spring should be topdressing before and after the arrival of beginning of autumn, especially rare organic liquid fertilizer. From the second year, in the peak season, topdressing organic liquid fertilizer once every 20 days. If it can be applied alternately with the mixed solution of 0. 1% urea and 0.2% potassium dihydrogen phosphate, the flowers and leaves will flourish more. Pot soil should always be moist, and it should not leak because of drought, but it should not be moist for a long time. If it is placed indoors to strengthen ventilation, it will be rotated to the outside in about 15 days. When you are indoors in winter, you need to see enough sunshine, and the lowest indoor temperature should not be lower than 8℃. Control water and prohibit fertilizer, pay attention to the door and window switches to avoid direct cold air blowing and smoke pollution. Scale insects and the prevention of sooty blotch. In North China, after the dry wind from late April to early May, it will be moved to outdoor maintenance. Milan can change pots every two years.

Milan should start pruning and shaping from the seedlings, leaving a section of trunk with a height of 15cm to 20cm. Don't let the main branches grow out of the soil, but prune them at the height of 15cm above the main branches to make the plants plump. The lower branches of perennial plants often age and die. Therefore, it is advisable to cut it every other year in high temperature season, so as to promote the germination of adventitious buds at the lower part of the main branch and grow new lateral branches, so that the tree can maintain a symmetrical posture, the tree is vigorous and the leaves are lush.
