Plumeria Rubra is not only of high ornamental value, but also a kind of Chinese herbal medicine that can be used as medicine. It can not only clear heat and relieve heat, but also stop diarrhea and cough and reduce phlegm, and can effectively treat heat stroke and cough and other diseases. And with the Plumeria Rubra, how do you propagate it? Then follow me to see propagation methods of Plumeria Rubra.
Plumeria Rubra: Cuttings are easy to survive and are mainly propagated from cuttings. Cuttings can be carried out all year round in tropical and subtropical areas suitable for open-field cultivation.1-2 - year - old thick branches were selected, and 20-30cm long branches were cut from the base of branches. Let the white milk flowing out of the mouth of the scissors dry naturally, or wash the milk flowing out of the incision with clean water, then put it in a cool and ventilated place for 2~3 days, and then cut it into the culture soil; Because just cut the branches with milk, cutting easy to infection and decay. The cuttings were inserted into a clean loam sand bed in the shed and then sprayed with water, once every 1 day, to keep the substrate moist. Root lasts 30 to 35 days. As long as not waterlogging, keep the soil moist, easy to survive. Plumeria Rubra is not strict with soil requirements, it should be planted in loose soil with more humus. Apply appropriate shading treatment in the early stage, and gradually adapt to open field growth later.
Layering propagation can be carried out in the growing season, but because of the easy survival of cutting propagation, layering production is rarely used.
Plumeria Rubra produces few results, but most varieties planted in open fields can also collect small amounts of seeds. After the Plumeria Rubra flowering, the seeds will open up naturally, and be removed from the pods and placed in pre - rain showers, in sandy, cultured soil beds. The suitable temperature for seed germination is 18-24℃, and it is usually picked and sown at the same time. Sow evenly at 5-6cm intervals and then cover with a thin layer of sand or coconut bran. Apply appropriate amounts of water to keep the substrate moist. In spring generally 8~12 days, and in summer generally about 5 days, it will take out germination. After the general routine management, keep wet, but the seedling bed can not waterlogging. When the seedling grows to 10-15cm, the bag is removed, and the seedling is cultivated with a 20cm×30cm bag. When the seedling grows to 40-50cm, the field is cultivated.
Grafting of Plumeria Rubra is easy to operate and the survival rate is high because of the affinity between rootstock and scion. Grafting can take place all year round in tropical and subtropical areas such as South China, but preferably in spring and autumn; In winter and spring, it is better to keep the air temperature stable above the average daily temperature of 18%. We should avoid winter summer long rain weather grafting.
Grafted Plumeria Rubra, prevent rain from seeping in early on in the graft, and prevent wind or other forces from shaking the grafted branches. When the bud and rootstock have healed, new leaves will soon appear on the next branch during the growing season. Other management work is consistent with routine flower and wood care.
And that's all for Plumeria Rubra propagation methods. Cuttings, layering, seeding, and grafting are all methods of propagation of Plumeria Rubra. You can choose according to your own circumstances, and thus cultivate the Plumeria Rubra.
