A kind of cutting seedling raising method of Photinia fruticosa

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of garden planting, and in particular relates to a method for growing seedlings of Photinia fruticosa by cuttings. Background technique [0002] Photinia is the collective name for the hybrid species of Photinia in the family Rosaceae. It is an evergreen small tree with a plant height of 4-6 meters. The leaves are leathery, oblong to obovate-lanceolate, and the new leaves are red in spring and turn green in summer. Autumn, winter, spring The three seasons are red, the color of frost is thicker, and the color of low temperature is better. Photinia frondosa has the characteristics of strong germination, resistance to pruning, easy cultivation, and rich leaf color changes. As a street tree, its pole stands like a torch, and as a hedge, its shape lies like a dragon. It is used for pruning and landscaping. The effect is beautiful. There are two common varieties, red robin and red lip, among which red robin has ...

Problems solved by technology

[0003] Most plants of the genus Photinia are usually propagated by sowing seedlings. It is difficult to meet the market demand for Photinia seedlings when it is limited by the source of seeds, the number of reproductive materials and the season, and the cycle is long and the variation rate of offspring is high.

However, Photinia fragrans is a hybrid introduced from abroad, and there is no report of fruiting so far. At present, tissue culture and cuttings are generally used for propagation.
