The propagation method of dragon spitting bead flower

Longtuzhu flower has a peculiar shape and blossoms luxuriantly, so it is suitable to be potted and ornamental. It can be used as courtyard cultivated tree species, and it is also a good potted plant. The branches of Longtuzhu are soft, the leaves are sparse, and the archway flower rack is tied to attract its branches. when flowering, the red Corolla protrudes outside the white calyx tube, such as the flat dragon spitting beads. Commonly used propagation is mainly cuttage, branch cutting, bud cutting, root cutting can take root.

[sowing and propagation]

The sowing time is usually from March to April. When the seeds are larger, they can germinate in succession about 10 days after sowing under the condition of indoor sowing pot and 24 ℃ at room temperature. When the seedlings are 10 cm high, they can be moved into small pots for maintenance, and they can blossom in the second year.

Sowing and reproduction take place in early spring. Because the seeds are large, they can be sowed on demand at a distance of 3~5cm at 24 ℃. It can germinate in about 10 days. If the seedling is too dense after emergence, it can be sparse and transplanted. When the seedling height is lOcm, it is planted in a small flowerpot with 3 plants in each pot, and it can blossom in the second year. When the new tip grows to 4-5 cm long, it is necessary to pick the heart in time to promote branching.

[ramet propagation]

After flowering, the new branches germinated on the underground stolon were dug up, potted directly with roots and maintained in a semi-shady place.

[cutting propagation]

Branch cuttings, bud cuttings and root cuttings are available. The branches can be inserted into the top twigs of the strong and disease-free branches, or the lower old branches can be cut into stem segments of 8 cm and 10 cm as cuttings. Budding is to take the lateral buds on the branches, with part of the xylem, as cuttings. The root cuttings are rhizomatous stolons cut into 8cm long as cuttings. The cutting bed can be made of peat, perlite, rotten leaf soil, river sand and vermiculite, and the cutting in spring and autumn is the best. The optimum cutting temperature is 21 ℃ and the bed temperature is 26 ℃, which is very beneficial to rooting. It can take root 3 weeks after insertion. If 0.5%-0.8% indolebutyric acid solution is used to treat the base of cuttings for 1-2 seconds, it can take root faster and more.

The branches can be inserted into the top shoots of strong and disease-free branches, or the lower old branches can be cut into 8~lOcm stems as cuttings, which can be inserted into a plain sand basin with a depth of 3-4cm. After insertion, pour water through the shade and high humidity place, keep the basin soil moist, keep the temperature at 20-25 ℃, and take root after about 3 weeks. Bud insertion is to take the lateral buds on the branches and take part of the xylem as cuttings. When changing the basin, the root stolon under the soil is cut into 8~lOcm segments as cuttings.
