Problems solved by technology

Among them, the sowing and seedling technology is strict, the seedling period is long, and the nursery is slow; the layering process is simple, but the number of reproduction is limited; cutting propagation is not limited by seasons, and the growth rate is fast after the cuttings survive, but the survival rate of common open field cuttings is only 60% to 70%. , low survival rate

Embodiment 1

[0016] Take the propagation of N. chinensis at the TEDA Plant Resource Bank in the Eighth Street of Tianjin Economic and Technological Development Zone as an example. The propagation of the brocade in this park is mainly carried out according to the following steps:

[0017] Production of strips:

[0018] ①In late October, select 1-year-old branches with good lignification, uniform and thick stems, relatively short internodes (5-7cm), well-developed buds, no pests and diseases, and no mechanical damage as seedlings.

[0019] ②Cut the collected seed strips into strips with a length of about 15 cm and containing 2 to 4 full buds. The upper incision is a horizontal incision, about 1 cm away from the upper bud, and the lower incision is oblique, wedge-shaped, and the distance from the lower bud Bract 2.0cm. The seed strips after cutting are bundled into bundles every 50 pieces.

[0020] ③ Immerse the bundled seed strips vertically in 10ppm naphthalene acetic acid solution, the ...

Abstract

The invention relates to a rapid propagation method of parthenocissus quinquefolia. The method comprises the steps of seedling preparing, seedling storing, nursery field preparing, cutting and managing after cutting. By propagating the parthenocissus quinquefolia according to the method, the seedling emergence rate can reach 90% or above, the disease resistance of seedlings is significantly improved, the probability that the seedlings are infected with bacterial diseases is greatly decreased, and beneficial conditions are provided for later transplanting.

Description

technical field [0001] The invention relates to a method for propagating lianas, in particular to a method for rapid propagation of broccoli. Background technique [0002] Wuyedijin (Parthenocissus Quinquefolia.L), also known as creeper and creeper, is a deciduous woody vine of the genus Vitiaceae, with branched tendrils and suckers at the top of the tendrils. The leaves are very variable, usually broadly ovate, with many 3-lobes at the apex, heart-shaped at the base, and coarsely serrated edges. Cymes, often born between the two leaves at the top of short branches. Flowers are small, yellow-green. Berry spherical, blue-black, covered with white powder. Flowering in June, fruiting in October. The leaves of Wuyedijin are dark green in summer, and turn red when the temperature difference between day and night is large after autumn. There are obvious seasonal changes. It is an excellent material for vertical greening, wall covering, and rock greening. In addition, it has s...
