The invention belongs to the technical field of seedling breeding, and in particular relates to a method for cultivating seedlings by cuttings of holly, comprising collecting the middle and upper parts of the semi-lignified branches of the current year on a mother tree of holly, and pruning the fringes and grading them according to the thickness of the fringes and the degree of lignification; According to the classification results of the cuttings, different concentrations of rooting agents were prepared for the cuttings with different lignification degrees for dipping; the loess soil, peat soil and perlite were layered and covered in layers from bottom to top to form a layered matrix bed; The substrate conditioner is evenly spread on the upper layer of the layered substrate bed; the cuttings soaked in the rooting agent are inserted into the layered substrate bed; and water control management. The invention effectively improves the survival rate and root quality of holly cuttings, solves the problems of insufficient supply of nutrients for root growth and poor root quality in the process of cultivating cuttings, and ensures high and stable yields of holly. |
