The invention discloses a cuttage
seedling culture method of
photinia serrulata. The method includes the steps of 1, preparing a
seedbed, wherein a single plastic
greenhouse with an external shading net is adopted for cuttage, the
seedbed is made after the ground in the
greenhouse is leveled, baffles are arranged around the
seedbed,
ultraviolet lamps are evenly arranged at the top in the plastic
greenhouse, a cuttage medium is prepared from camellia seed
husk powder, folium artemisiae argyi
powder, yellow soil and fine sand in a mixing mode, the seedbed and the cuttage medium are irritated by the
ultraviolet lamps at intervals before cuttage and then covered with a
plastic film, and water is sufficiently sprayed to the seedbed for cuttage; 2, performing cuttage of cuttings, wherein semi-lignified shoots or lignified current-year branches are selected as the cuttings, the cuttings are treated with a rooting agent before cuttage, soil is sufficiently irrigated with
oxygen-rich water immediately after cuttage, a
carbendazim and
thiram mixed solution is sprayed to leaf surfaces for disinfection, and then the
ultraviolet lamps are turned on for
irradiation; 3, performing post-cuttage management. By means of the method, diseases such as gray mold and the
leaf spot disease or pests such as coccid can be reduced in the cuttage propagation process of
photinia serrulata, the cuttage propagation efficiency can be improved, and the
survival rate can be increased.
