The latest culture method of Cinnamomum chinense

Japanese osmanthus is a horticultural variety of sweet-scented osmanthus, also known as rhinoceros, Jiuli incense, golden millet and so on. It gets its name because of its continuous flowering and strong aroma. It integrates the functions of greening, fragrance and coloration, and can be cultivated into graceful globular small trees. It can also be cultivated into spherical shrubs with dense branches and leaves, and can also be used for pot planting or flower arrangement. Let's take a look at the breeding methods of Japanese osmanthus.

Growth habits of Cinnamomum chinense

Cinnamon has wide adaptability, strong stress resistance, like neutral acid, rich in organic matter soil, requires a cool and humid microclimate, has a certain degree of cold resistance. The sprouting period is earlier every year. Potted plants can bloom normally in Northeast and North China, and can survive the winter safely in the south of Qinling and Huaihe River. they can also adapt to the higher temperatures in Fujian, Guangdong, Guangxi and Hainan, and can blossom as scheduled every year. Its flower buds can differentiate continuously, and it has the strange characteristics that spring buds bloom and Lignified old branches can also produce dense buds and blossom. As a result, the long-term flowering and the continuity of flowering of cinnamon were ensured. In that year, the two-leaf seedlings bloomed, which is difficult to compare with ordinary sweet-scented osmanthus.

Propagation method of Cinnamomum chinense

1. Branch pressing propagation: usually at the end of March and the beginning of April, around the female parent, depending on the number of pressed branches, dig a ditch of 20 cm in depth and 20 cm in width along the direction of the natural extension of the branches, and then press the branches into the ditch. Fill the ditch with fertile soil and step on it, and then cultivate the soil of the pressed branch into a steamed bread after pouring enough water.

2. High-altitude pressing: usually between September and October, the bamboo tube is broken into two pieces, filled with wet soil, placed on the sturdy branches of cinnamon, supported by another bracket, often add water, keep the tube moist, and new roots can be born after more than a month. The following spring, take off and transplant, that is, into a sweet-scented osmanthus tree, about 3 years can blossom.

3. Seed propagation: at the end of May and the beginning of June every year, the ripe drupes of osmanthus trees are picked, shelled, dried and stored in wet sand. It will be sown on the pre-prepared seedbed in the early spring of the following year and can sprout and take root when the weather gets warmer in March. Generally, the annual seedling height can reach about 15 centimeters, and it can grow to 1 meter high in 2 to 3 years, then it can be planted out of the nursery.

4. Grafting propagation: one-year-old strong lateral branches were selected from trees about 20 years old, two buds were cut, grafted on privet rootstocks, wrapped with plastic film cutting strips, and germinated in the same season. It can blossom after 4 years, but the trunk of sweet-scented osmanthus trees propagated by this method is not straight and is not suitable to be used as street greening trees.

5. Cutting propagation: in the cutting season, when the sap is about to flow in February, one month before cutting, the cutting bed is sprayed with trichlorfon 800-1000 times liquid to eliminate nematodes. 10 to 15 days before insertion, disinfect the bed with lime water and rinse the bed with clean water 3 days before insertion. After inserting and compacting the bed soil, cover the grass between the rows, soak through the water once, and build a shade rack, when the new branches grow to more than 6 cm, they can be removed from the nursery bed.

Culture method of Cinnamomum chinense

1. Soil selection: cinnamon should use loose and organic sandy loam, as well as bacterial dregs, sawdust, peat, mountain forest rotten leaf soil, etc. (the selection of substrate should make potted flower roots grow and breathable). The pH of the matrix is neutral and slightly acidic, and after selecting the matrix, it is best to carry out disinfection and sterilization (such as the use of topiramate, diazepam, carbofuran and other drugs).

2. Reasonable watering: the plants just planted with Japanese cassia should be watered once, and the moisture requirements are the same as other flowers and trees. Too dry and wet soil will affect the growth and development, and it is found that young branches and leaves wilt. The flowerpot should be put into a clear water basin at 1/4 of the pot soil for about 1 hour to return to normal, and excessive moisture will cause hypoxia and rotting of the roots. But avoid watering tea water, washing powder water and other alkaline water.

3. Timely fertilization: Cinnamomum cassia consumes more nutrients because of its continuous flowering, so more phosphate fertilizer should be applied to promote its continuous flowering. Based on this point, the fertilization standard should follow the principle of "thin fertilizer and diligent application". Usually can also add some organic fertilizer, but do not fertilize too much, fertilization should be combined with watering, generally a florescence.

4. Shaping and pruning: Cinnamomum cassia should cut off some long branches, over-dense branches, withered branches, diseased branches and so on according to the tree shape, and some twigs should be trimmed for the newly planted potted flowers. Pruning is usually carried out after the tender shoots germinate, but before Lignification.

5. pest control: the common diseases of Japanese cinnamon are leaf blight and anthracnose, which can be controlled by 800x solution of "carbendazim" and "topiramine". The common pests are red spider and scale insect, which can be controlled by 1000-fold solution of "dicofol" and "Cockworm" respectively.

Daily maintenance of Cinnamomum chinense

1. Light management: cinnamon prefers light. Where there is plenty of sunshine, the leaves are green, the branches are stout, and the flowers are fragrant. If it is placed in the shade where the sun is insufficient, the branches and leaves will be scarce and the fragrance of flowering will be light. Cinnamomum chinense grows most vigorously when the temperature is from 15 ℃ to 30 ℃, but it burns young leaves and buds in summer, so pot seedlings should be placed in a well-ventilated shade in midsummer.

2. Temperature control: the lowest limit temperature of the birthplace of Japanese cinnamon is-7 ℃, the maximum limit temperature is 38 ℃, and the normal flowering temperature is from 2 ℃ to 22 ℃. If the summer temperature is too high, it can not reduce the temperature and increase humidity through foliar water spraying, and heat preservation should be carried out if the temperature is too low in winter.

3. Humidity control: Japanese cinnamon likes to be warm and moist, and the normal humidity can be controlled at 70% to 85%. The loss of water in the basin soil will make the leaf edge scorched and dry. Summer and autumn temperature is high, the air is dry, want more watering, keep basin soil moist, at the same time often spray water to plant and basin surface. Watering in winter and spring should be reduced appropriately. In the process of plant growth, water should not be accumulated in the basin, otherwise it is easy to cause root rot.

4. Turn the basin and change the soil: Japanese cinnamon has strong vitality, so it is necessary to pour the basin and change the soil every year, so as to avoid a large number of fibrous roots touching the basin and affect the absorption of water and fertilizer. The best time to change the basin is from February to March in spring and from September to October in autumn. When changing the soil in the basin, part of the original soil (root) should be retained, and the rest of the root soil should be removed, and the new nutrient soil should be filled around the edge of the basin, watered thoroughly, maintained in the shade for about 20 to 30 days, and moved to the ventilated and sunny place for management.

5. Promoting flowering: the best temperature for flower bud differentiation of Cinnamomum chinense is 6 ℃ to 8 ℃, the maximum temperature of flowering is 16 ℃ to 18 ℃, and the air humidity is 75% to 85%. At the same time, there should be some short-day illumination, so we can promote its flowering by improving the small environment (such as wiping buds to control its vegetative growth, shading to control light, foliar spray to reduce temperature and increase air humidity, etc.).
