The following is to talk about the breeding methods and cultivation techniques of longevity flowers.

Reproduction method

Cuttage

The effect is best in May-June or September-October. Select a slightly mature fleshy stem, cut it 5-6 cm long, insert it in a sand bed, cover it with a thin film after watering, and take root at 15-20 ℃ at room temperature. It can be potted in 30 days. Ten centimeter pots are commonly used. If there are not many seedlings, leaf cuttings can be used. Cut the sturdy and full leaves from the petiole, insert them obliquely or horizontally on the sand bed after the incision is slightly dry, and maintain humidity for about 10-15 days, they can take root from the base of the leaves and grow new plants.

Tissue culture

In the United States and France, stem tops, leaves, stems, flower buds and flowers of Christmas cabbage were used as explants in the late 1970s, and adventitious buds were induced in MS medium with 2mg / L kinetin and 0.1mg / L naphthylacetic acid. Then rooting was induced by 1/2MS medium plus 1 mg / L indolebutyric acid. Plantlets can grow after 4-6 weeks at room temperature 25-27 ℃ and light for 16 hours. [2]

Cultivation techniques

After the potted plant, it grew more vigorously in a slightly humid environment, and the reddish air was constantly rooted in the internodes. If the temperature is too low or too dry, the growth slows down, the leaves turn red and the florescence is delayed. In midsummer, watering should be controlled and ventilation should be paid attention to. If it is hot and humid, the leaves will rot and fall off. Fertilizing once every half month during the growing period, you can also use "Huizhi" 15-15-30 special fertilizer for potted flowers. In order to control the height of the plant, 1-2 coring should be carried out to promote more branches and more flowering. Two weeks after planting, the cabbage was sprayed with 0.2% for a long time, and the plant height was 12 cm and sprayed again. In this way, the plant height can be effectively controlled to achieve the effect of beautiful plant, green leaves and many flowers. In the process of flower bud formation in autumn, phosphorus and potassium fertilizer can be applied for 1-2 times.

At the same time, in the process of longevity flower cultivation, short-day treatment can be used to adjust the florescence to achieve the purpose of providing potted flowers all the year round.
