Abstract

The invention relates to a cultivation method of a tree-like winter jasmine. The method comprises the following steps: (1) selecting a rootstock and scion, namely, selecting a ligustrum vicaryi seedling with the chest diameter more than 2cm and the trunk height of 130cm to 300cm, and adopting the ligustrum vicaryi seedling as the rootstock; selecting a new-born jasmine branch with diameter of 0.2cm to 0.5cm from the jasmine seedling to be used as the scion; (2) top-grafting, namely, carrying out the top-grafting by adopting the ligustrum vicaryi seedling obtained in the step (1) as the top-grafting rootstock and the new-born jasmine branch as the scion in a cleft grafting manner, a cutting grafting manner or a bark grafting manner; (3) cultivating a new crown, namely, carrying out the sealing and moisture maintaining by utilizing a plastic film bag after the top-grafting is completed, and increasing the fertilizing amount and watering amount; cutting back the new-born jasmine branches each time when the new-born jasmine branch grow to 5cm to 10cm, and removing the new-born branches of the rootstock at any time; obtaining the tree-like jasmine after 2 to 3 years. The cultivation method of the tree-like winter jasmine is simple and easy, the survival rate is high, and the obtained tree-like jasmine is high in ornamental value and relatively high in popularization value.
