A kind of method for cultivating seedlings of purple leaf dwarf cherry group

Abstract

The invention discloses a method for cultivating seedlings of a purple leaf dwarf cherry group, relates to plant propagation, and belongs to the seedling production technology in forestry biotechnology. It is characterized in that: fumigation and disinfection are carried out in the intelligent seedling-growing greenhouse, the stem section of Ziye dwarf cherry is selected, and after surface sterilization, it is cut into 2-3 cm stem sections with terminal buds, placed on a reciprocating shaking seedbed, and the stalks are sterilized with an additional 6‑BA (1.0mg / l) and NAA (0.05mg / l) adventitious bud medium culture; when the plant grows to 2.5 ~ 3.5cm, transfer to the other half of the reciprocating shaking seedbed, with additional IBA (1.0mg / l ) and IAA (1.0mg / l) rooting medium to induce rooting. After 35 days, the seedlings were hardened for 5 days and moved to a nutrient pot for propagation. The present invention combines traditional seedling raising and group seedling raising methods together, through reciprocating shake seedbed shallow shock culture, avoids the weakness of liquid culture medium that is easy to cause the death of culture due to lack of oxygen and slow growth of solid medium, and achieves large-scale rapid growth. The purpose of breeding, and the process is simple, easy to popularize.

Description

technical field [0001] The invention relates to the production technology of rapid propagation of seedlings in the forestry biotechnology, in particular to a method for cultivating seedlings of the purple leaf cherry group. Background technique [0002] Purple leaf dwarf cherry (Prunus×cistena N.E.Hansen ex Koehne) belongs to Rosaceae Prunus deciduous small trees or shrubs, plant height 1.5-2.6m, crown width 1.2-2.9m, young branches purple brown, usually glabrous, old branches have Lenticellae, distributed throughout the branches, single leaves alternate, long ovate or ovate-oblong ellipse, 4-8cm long, apex acuminate, leaf base broadly cuneate, leaf margins have irregular fine blunt teeth, leaf surface red Or purple, bright purple at the top of new leaves. The flowers are solitary, small, pale pink, with 5 petals, slightly fragrant, with many stamens and single pistil, and the flowering period is from April to May. [0003] Purple leaf dwarf cherry is a hybrid of purple le...

Problems solved by technology

[0004] Purple leaf dwarf cherry is generally propagated by grafting and cuttings, cutting grafting in spring and autumn or budding in summer and autumn, and mass propagation is very inconvenient

Moreover, because the seedlings of purple-leaved dwarf cherry are relatively slow, they can be applied to projects at least three years, and it takes four to five years for them to grow. Obviously, traditional grafting and cutting propagation methods are far from being able to meet large-scale landscaping projects. construction needs
