Coral trees grow fast and absorb a lot of water, so they should be cultivated in fertile and humid soil. After cultivation, it should be watered with enough root water, and then watered or irrigated according to soil or weather conditions. We can use watering, spraying, irrigation ditch water and other methods. It should be a matter of time before watering. Seedlings should be watered several times in April-May in the early growth stage, once in June-August in the fast growth stage, and irrigation should be controlled in the late growth stage, except for special drought, which is generally not watered. The principle of early weeding, small weeding and no damage to coral seedlings should be mastered, which requires. We should leave the weeds in the nursery and weed them artificially after it rains or is watered to dry. Actively promote chemical weeding, roundup or glyphosate can be used in the aisle, but it should be prevented from spraying on the seedlings. Gramineae weeds are tender in the early stage, so Gaicaoneng or Jingcaoke can be used. If it is the first time to use herbicides, try them before use to avoid phytotoxicity. Combined with weeding and loosening soil, the soil is loosened from shallow to deep 4-6 times a year, which is shallow near the roots of seedlings and between 5 plants and deep between rows. Coral likes deep and fertile soil. In rainy season, about 750kg/hm2 of compound fertilizer and 300kg/hm2 of urea can be deeply applied. Urea can be applied several times a year from May to August.

Coral trees, also known as Castanopsis kawakamii, Sargassum, france holly, coral branches, Caprifoliaceae, Viburnum, evergreen shrubs or small trees, have taupe bark and lenticels on their branches. Leaves opposite, leathery, petiole brown, ovoid to elliptic-oblong, 7-15cm long, apex acute to nearly round, margin entire or irregularly shallow, lateral veins 4-5 pairs, protruding downward. The panicle is pyramid-shaped and 5- 10 cm long. The flowers are fragrant; The calyx tube is about 65438 0.5 mm long, with five shallow blunt teeth on the calyx brim, and the corolla is white and radial. The corolla tube is about 65438 0 mm long, with lobes 5, 2-3 times as long as the corolla tube and 5 stamens, which are inserted near the throat of the corolla tube. Drupe is ovoid, rectangular, long 10 mm, first red and then black, and the depth of pit is 1. Coral trees like warm, dry and sunny environments. Not cold-tolerant, semi-cloudy, drought-tolerant. Fertile and well-drained sandy loam is needed. Like neutral soil, it can also adapt to acidic and slightly alkaline soil, has strong resistance to toxic gases chlorine and sulfur dioxide, has certain absorption ability to tribute and fluorine, is smoke-resistant, has strong fire resistance, developed root system, is easy to shape, is pruning-resistant, is transplant-resistant, and grows rapidly.

Coral trees change pots every spring and add fertile, well-drained humus and coarse sand mixed soil. Keep the basin soil slightly dry during the growing period and apply fertilizer 1 time every month. If there is enough fertilizer and water, the stem nodes grow fast, the thickness is uneven, and the plant shape is not good. At the same time, long stems tend to droop and are not straight. In addition to a little shade when the light is too strong in midsummer, you need plenty of sunshine. In this way, the deformed stems are not compact in growth, green in color and good in ornamental effect. The temperature in winter is not lower than 5℃. Before moving indoors for maintenance, just trim and reshape the plant slightly. France holly, also known as Coral Village, is an evergreen shrub or small tree belonging to Podophyllaceae, which is produced in South China, East China, Southwest China and other provinces. Cities in the Yangtze River valley are cultivated, and East Asia and India also produce them. Pijuanhua blooms in spring, and the fruit is red in cold and autumn, hanging on the branches like coral, so it is also called coral tree. France holly is a well-preserved landscape tree species. Because of its unique fire resistance and dust retention, it is widely used as a fire isolation tree, landscape tree or hedge, and it is the first choice for landscaping in airports, highways and residential areas. The cultivation of sweet taste in france holly is mainly based on pressing sweet taste branches, and sweet taste can also be planted. It is not only simple and convenient, but also takes root quickly and has a high survival rate, because it is widely considered to be suitable for production.

Branch pressing can be carried out all year round in france holly, and it is most suitable in late spring, early summer and early autumn. In the cold winter, we should keep warm in the place where the seedlings are raised. Annual thick branches with satisfactory growth and development on young trees or strong mother trees are the easiest to survive. After harvesting, the cutting should be carried out in a cold and leeward place, and the tools used should be sharp. When cutting, cut off the branches with branchlets 0.5cm above and below each node, then cut the stem nodes in half according to the planting position of the branchlets, and press the branches into two branches. For branches without branchlets, two nodes must be left. The upper end is cut into flat segments at 1cm above the bud, and the lower end is cut into horse-ear or flat segments at 0.5cm away from the bud. After cutting, soak the cuttings in 500ppm NAA or 200ppmA abnormal rooting powder for 5 seconds, and then cover them with wet straw or wrap them with agricultural film to avoid drying.

Cuttings in france holly can be carried out all year round, with late spring and early summer and late summer and early autumn being the most suitable. Seedbed insulation should be done in winter cuttage. One-year-old stout branches with good growth and development on young trees or strong mother trees are the easiest to survive. After the cuttings are collected, they should be cut in a cool and leeward place, and the tools used should be sharp. When cutting, the branches with branchlets between nodes should be cut 0.5cm above and below each node, and then the stem nodes should be cut in half according to the planting position of branchlets. For branches without branchlets, two nodes must be left. The upper end is cut into flat segments at the position 1 m above the bud, and the lower end is cut into horse-ear or flat segments at the position 0.5 cm away from the bud. After cutting, soak the cuttings in 500ppm of tea acetic acid or 500ppm of mABT rooting powder for 5 seconds, and then cover them with wet straw or wrap them with agricultural film to prevent drying.

France holly cutting should be shallow, not deep, and the cutting level of branchlets should be downward, and the depth of mother plants should be1cm. The cutting depth of big branches is 1 cm when the next stem node is inserted into the middle and upper part, and the cuttings are inclined to the ground by about 45 degrees. Shallow and oblique cuttings are beneficial to rooting and survival in advance. After cutting, the soil around the cuttings should be compacted and watered once immediately to make the lower part of the cuttings stick to the soil. Generally, the row spacing of cuttings is 12- 15cm, and the plant spacing is 6-8cm. When cutting, it is not advisable to leave too many leaves on the cuttings or to cut them all off. The lower leaves can be cut off with the petiole, and the upper leaves are left with 2 pieces. According to the size of leaves, each leaf should be cut off from 1/2 to 2/3 to reduce excessive consumption of water and nutrients.

Generally, the propagation mode of coral beads is mainly leaf cutting. Just pick healthy leaves and lie flat on the slightly wet soil. Sufficient temperature and humidity make it easy to take root. It can withstand the low temperature of MINUS 5 degrees in winter without water supply. Temperature seems to have little effect on it, and it can grow all year round. If there is enough light, it will be red all year round. Coral beads like the growth environment with sufficient light, and they are succulents in winter, dormant at high temperature in summer, and fully sunny in the growing season except summer. Attention should be paid to proper shading in summer and planting in indoor air-conditioned rooms in winter.
