Anti-season quick breeding method for Arundo donax

Abstract

The invention is a method for rapid off-season breeding of floral-leaf reeds, relating to the field of flower and plant breeding and growing. The rapid breeding is achieved by the following steps: under the climate of middle December in Southern China, a stem of a one-year-old floral-leaf reed is scissored and soaked on the water surface in a 50cm deep sink; a double-layer plastic film is used for sealing purpose; at the noon of a fine day, the plastic film is kept open for 1-2 hours after the water temperature exceeds 15 DEG C; the water quality is remained sound, Spirogyra and other algae substances are removed from time to time; in middle March of next year, the stem can be scissored at the internode and moved to a needed environment when the sprout of the floral-leaf reed grows above 10cm and the adventitious root grows above 10cm. The implementation of this invention can make the floral-leaf reed meet the requirement of transplantation more than 30 days ahead of the scheduled time. The breeding factor is increased from the original 1:5 to 1:20; the cost is reduced from the original RMB1-2 / reed to RMB 0.1 / reed. Thereby, the demands of large quantity of seedlings are satisfied, the breeding method is simple and the application is easy to promote.

Description

technical field [0001] The invention relates to the technical field of flower and plant propagation and cultivation, and relates to a rapid propagation and cultivation method, in particular to an off-season rapid propagation method for mosaic reed bamboo. Background technique [0002] Arundo donax var.versicolor, originally distributed in the European Mediterranean region, is a variety of Arundo donax var. versicolor, a perennial emergent herbaceous foliage plant. The stems are tall and straight, like bamboo, and are excellent foliage plants in wetlands or waterscapes. When the temperature is lower than -5°C, the above-ground part of Arundis mosaic shrivels and dies. The pollen of the plant is aborted and seed reproduction is not possible. [0003] At present, the propagation method of Mosaic Reed Bamboo used in gardens is mainly tillering propagation, which can only meet the transplanting requirements in May of the following year, and the propagation speed is relatively s...

Problems solved by technology

Although the propagation method of tissue culture can increase the reproduction speed and reproduction coefficient, it requires large-scale instruments and equipment such as incubators and ultra-clean workbenches, and requires professionally trained personnel to operate, resulting in high production costs.
