Grafting method of camellia japonica

The invention discloses a grafting method of camellia japonica. During three grating periods, three methods of grating camellia japonica to the camellia tree stumps are adopted at the same time. In the first period, branches of camellia japonica are grated to external branches of the camellia tree stumps after the camellia tree stumps are transplanted. In the second period, branches of camellia japonica are grated to buds of internal branches of the camellia tree stumps within a month after internal branches of the camellia tree stumps germinate. In the third period, buds of camellia japonica branches are grated to internal branches of the camellia tree stumps when the camellia tree stumps grow vigorously next year by field planting. A grating method with grafting survival rate higher than an independent period is obtained. Flowers can bloom in advance after grafting. The duration for forming corollas is shortened so that camellia japonica with great economic value can be rapidly obtained. Refined camellia japonica trees with corollas can be acquired within nine months after grafting. The scion survival rate is up to above 85%.
