1. Soil: Michelia is a fleshy root, which is not resistant to dryness and barren, and is also afraid of stagnant water. It requires well-drained and fertile slightly acidic loam and neutral soil, and 4 parts humus soil, 3 parts garden soil, 2 parts decomposed manure soil and 1 part sandy soil can be used as culture soil.
2, watering: smile to keep the soil moist at all times, but never too wet. Because its roots are fleshy, if it is watered too much or waterlogged after rain, it will become rotten roots, so we should pay attention to controlling humidity in rainy season. During the growing period and before flowering, it needs more water and is watered once a day. In summer, it is necessary to water the leaves in order to maintain a certain air humidity. Because of the short sunshine in autumn and winter, water once or twice a week.
3. Sunshine: In summer, plants with smiles should not be exposed to the sun, and they need 30% shade to avoid strong light burning the leaves. They can be placed on indoor windows and balconies facing east, or under shady trees or sheds outside. After the autumn is cool, you can see more sunshine. In winter, put it indoors in a sunny and ventilated place.
4. Temperature: The minimum temperature of Michelia is not lower than 5℃. Once the temperature is lower than 5℃, the normal physiological activities of plants will be affected, the absorption capacity of roots will be weakened, and the stems and leaves of plants will wither. At the same time, the maximum temperature should not exceed 65438 05℃. If the temperature is too high, the nutrients in the plant will be consumed too much, which is not conducive to the growth of the next year. Therefore, it is appropriate to keep the room temperature of Michelia at 5℃ to 15℃ in winter.
5. Fertilization: Smilax China fertilizer, decomposed cake fertilizer, bone meal, chicken and duck manure, fish intestines and other compost are mixed with water. Fertilize once every 15 days in the growing season (April-September), and stop fertilizing after flowering 10. If the leaves are not bright and dark green, you can fertilize them once.
6. Insect pests: Michelia often suffers from scale insects, which can also induce soot disease. Scale insects can be brushed off with a small brush or sprayed with 20 # petroleum emulsion with 150 times of water, scrubbed with clean water or sprayed with carbendazim aqueous solution with 500 ~ 1000 times of water to prevent soot disease.
Second, the growth environment of smiling flowers
Smiling peanuts grow in shady mixed forests, especially along valleys, which are fertile and semi-shady. It grows best in weak shade, avoiding direct sunlight, paying attention to shading in summer, moving into greenhouse before late autumn frost, and wintering at around 10℃. The laughing gas flower is a warm woody shrub, which is not cold-resistant, and can overwinter in the open air in the leeward and sunny places south of the Yangtze River. Not tolerant of dryness and barrenness, but also afraid of water accumulation, it needs well-drained, fertile slightly acidic loam and neutral soil to adapt.
Third, the cultivation value of Michelia.
1. Indoor viewing: The branches with smiling flowers are elegant, the leaves are green and attractive when they bloom. It is a foliage plant, and potted plants have high ornamental value indoors.
2. Improve the air: Smiling, like other plants, has a certain fresh air function, and the floral fragrance of smiling is elegant and charming, giving people a strong indoor comfort, and the effect of improving indoor air is obvious.
3. Medicinal value: Michelia tea can not only make people feel happy and cheer up, but also has the magical effects of promoting blood circulation, regulating menstruation, caring skin, calming the nerves and reducing stress, slimming and strengthening the body, promoting health and strengthening the body, and eliminating diseases and prolonging life.
Extended data:
Matters needing attention in Michelia cultivation
1, Michelia root hypertrophy, not resistant to transplantation, transplant should bring more soil balls, and properly sparse branches and leaves, such as loose soil balls during transplantation, you must cut branches and leaves again in time, otherwise the whole plant will easily die.
2. Smile is not resistant to early drying, thin, afraid of waterlogging, and likes fertile, loose and slightly acidic loam with good drainage.
3. Michelia plants should be properly ventilated and transparent during wintering to avoid the harm of pests such as aphids and scale insects.
4. The watering time of smiling flowers should be chosen when the temperature is high at noon, and the greenhouse should maintain proper humidity.
5. If you don't leave any seeds after laughing, you should cut off the young fruits in time to reduce nutrient consumption.
