Sowing is a common method of seabuckthorn propagation, which is divided into spring sowing and autumn sowing, before which seed soaking is usually needed, so as to improve the germination rate.Prepare loose and fertile soil, bury seeds in it and water them thoroughly once, which can promote rooting and germination.In order to improve the germination rate, more than one seedling is often sown when sowing, and then thinning is carried out after growing.
Seabuckthorn cuttings are mostly carried out in June, select semi-lignified branches, length between 7-10 cm, remove the leaves below it, cut the mouth to be flat.Soak the bottom in an indolebutyric acid solution for 12 to 24 hours to promote rooting.If the degree of lignification is relatively low, the soaking time can be shortened.Then use peat and sand as a substrate, insert the cuttings on it, and then water it to keep it moist.
Hippophae rhamnoides is usually grafted in March, and cleft grafting is often used.The rootstock is often used as the rootstock, and the thickness of the scion should be similar to that of the rootstock, so as to facilitate the healing of the two.The scion is usually a 2-3 year old branch, which should be cut into 5 cm segments, and the bottom should be cut into a wedge shape, which should be inserted into the incision of the rootstock, after ensuring the fit of the two, it can be tied with a plastic belt.
Seabuckthorn layering should be carried out before the buds sprout in early spring, and a biennial branch with a length of about 15 cm should be cut.Ring the base of the branch, then pull the branch down, bury the ring in the soil, wait for it to take root and sprout, and then separate from the mother plant.
