The branches are flat and fleshy, and each node is in the shape of a rectangular leaf with 1 ~ 2 blunt teeth on each side, and the top is flat. Flowers have solitary branches and neat corollas, and there are many colors, such as purple, red and white. Attention should be paid to distinguish it from crab claw orchid and false epiphyllum. [Edit this paragraph] Originated and distributed in tropical forests in South America, it is cultivated in many countries in the world. In addition to purple, there are white, orange, pale yellow and crimson varieties. [Edit this paragraph] Growth habits like warm and humid climate, and the soil should be rich in organic matter and well drained. During the growing season, the soil should be kept moist. Apply thin fertilizer every two weeks. The optimum growth temperature is 19 ~ 32℃, and the optimum growth temperature in winter is 7 ~ 13℃. Slightly resistant to shade, it should be in a semi-shade environment. In summer, direct sunlight should be avoided. In summer, it often sleeps at high temperature, so there is little water. It is a short-day plant that blooms in winter. [Edit this paragraph] Propagation by cutting or grafting. In the growing season, April-May is the most suitable, and 1-4 stem or branch cutting can be used. When cutting, the wound does not touch water, and it is dried in the dark for two or three days to make the wound heal and not rot easily. Before transplanting, take root in the shade, water less, and take root in about 20 days. Immortal refers to easy to take root, but the roots are thin and weak, and they are not resistant to water and humidity, so they are often grafted on other cactus plants with strong roots, which can accelerate their growth. Commonly used rootstocks are cactus, cactus, cactus, celestial ruler and so on. Cuttings or grafted seedlings usually bloom for two years. Under the condition of short sunshine (8 ~ 12 hours per day), flowers can bloom in 2 ~ 3 months. Shading treatment is carried out at the beginning of July, and flowers can bloom at the end of September. Fairy refers to applying rare organic liquid fertilizer every 2 ~ 3 weeks during the growing period, or applying a small amount of compound fertilizer. After the bud is formed, the pot soil should not be too dry or too wet to prevent the bud from falling off. Cutting propagation cutting matrix: it is nutrient soil or river sand, peat soil and other materials used for cutting. Due to the limited conditions, it is difficult to find an ideal cutting substrate for home cutting. It is recommended to use the prepared and sterilized cutting media provided by this station. Medium and coarse river sand can also be used, but it should be washed with clear water several times before use. Sea sand and river sand in saline-alkali areas are not suitable for the growth of flowers and plants. In the growing season of early spring or late autumn (the highest temperature at noon is not higher than 28℃, and the lowest temperature at night is not lower than 15℃), cut off leaves or stems (with 3-4 leaf nodes), insert the wound into the substrate after drying, and spray the cuttings and substrate slightly. As long as the substrate is not excessively dry or flooded, roots and new buds can grow rapidly. When the temperature is high in late spring and early autumn, cuttings are easy to rot, so it is best not to carry out cuttings.

Immortals refer to plants with beautiful shapes and gorgeous flowers, which can be cultivated indoors with insufficient sunshine and can be used to decorate the study and living room. [Edit this paragraph] The flowering period of maintenance and pests and diseases is about 65438+ 10. Water, light and temperature can be controlled in cultivation to promote flower bud differentiation and development. At the end of August, when the sunshine gradually becomes shorter and the temperature begins to drop, gradually reduce the moisture, stop fertilizing and put it in a cold place (as low as 5℃). After more than 13 hours of darkness every day, flower buds can gradually form at the tip of the stem, and the flower buds are spherical. After the flower bud is formed, it can develop and open under normal growth conditions, that is, proper watering and slightly higher temperature. If the potted fairy fingers are placed on the wall, the branches will extend to one side and droop gradually, which can be as long as 50cm. If you see light on all sides or rotate the basin frequently, it will grow evenly on all sides. When it grows to a certain size, you will often make several layers of brackets to hold the drooping branches, otherwise it will hang around the basin. The prevention and control of pests and diseases must be based on prevention, with special attention to the prevention and control of stem rot and scale insects. For general diseases, carbendazim, chlorothalonil and thiophanate methyl can be used alternately. During the incubation period around May, imidacloprid, chlorfenapyr and other drugs can be used to control scale insects. Drugs for general diseases and insect pests can be mixed, and foliar fertilizers can also be added, such as some conventional trace elements and so on.
