Introduction to cordate telosma, also known as night fragrant flowers, night fragrant trees, night fragrant flowers, tuberose, night orchids, etc. , a flowering plant native to tropical America. Its twigs are tender, hairy, milky white, and its flowers are yellow-green, with a clear fragrance, especially at night. Most of them are potted ornamental plants, but they are not suitable for indoor use, and their fragrance makes people breathe hard.

Second, the species cordate telosma is another name for many plants. More common are: Mirabilis jalapa; Nocturnal tree: another name for nocturnal tree of Solanaceae; Tuberose: another name for tuberose of Amaryllidaceae; Cordate telosma: another name for cordate telosma, evening primrose and willow. There are 12 species of tuberose, but only tuberose is cultivated and utilized.

3. The environmental requirement for the growth of cordate telosma is 1, with loose soil, good drainage and rich organic matter. Gaza of peat soil and humus soil is prepared in the ratio of 3∶3∶4 respectively. The bed soil thus prepared has the characteristics of increasing bed temperature, retaining water, permeability, fertility and strong acidity, and is suitable for branches to take root and sprout. 2. The propagation method of luminous cordate telosma is sunny, but it should be avoided in the scorching sun at noon in summer. 3. Move the temperature into the shed in the middle and late period of 10 every year, and keep the temperature in the shed at 8℃ to 12℃. If the temperature is lower than 5℃, the leaves will wither and fall off until they die.

Fourth, the method of watering cordate telosma is the peak season for growth. In addition to applying enough fertilizer, the soil in the basin must be kept moist frequently, and watered twice a day if necessary. If it is a seedling, spray water 1 2 times a day. V. Fertilization Method During the growth of cordate telosma, it is necessary to apply 10- 15 days of dilute decomposed liquid fertilizer, so that it can continuously produce fragrance from mid-May and improve its ornamental value. If we can apply NPK compound fertilizer, the effect will be better.

Six, the propagation method of cordate telosma mostly adopts cutting propagation, combining pruning in spring and autumn. Select annual stout branches, cut them into cuttings with a length of 8- 10 cm, put them into a pot filled with half sand, take root after 1 month at a temperature of 20-24℃ and frequent water spraying, and then cut them into pots or insert them. VII. Pruning methods The branches of cordate telosma grow faster. If left to grow naturally, 1 year can grow to about 1 meter, so pruning is needed every year to grow more lateral branches and flowers. Pruning is usually carried out in autumn, and each side branch is kept 10- 12 cm long. Dry branches and over-dense branches should be cut off after the flowers wither.
