Problems solved by technology

Although the method of seed propagation is simple and the reproduction coefficient is large, it is easy to cause variation in plant traits
At present, there are many reports on the cutting propagation of Euonymus plants, but the literature on the cutting propagation of Euonymus aureus is almost blank

Embodiment 1

[0029] (1) Preparation of the nursery for the female parent: Plant seedlings in a field with a row spacing of 20×30cm, and plant seedlings for 3 years.

[0030] (2) Cutting time and place: Cuttings will be carried out in the greenhouse of Jiangsu Agriculture Expo Garden from May 1st. The top of the greenhouse is covered by plastic film, and the plastic film is covered with double-layer shading nets. The light intensity is controlled to 50%, and the intermittent automatic is adopted. The spray device controls the relative humidity of the air at 70%, and uses the greenhouse water curtain system to ventilate and cool down to maintain the temperature at 22°C.

[0031] (3) Preparation of cutting substrate: The cutting substrate is sandy soil: peat soil: garden soil: organic fertilizer = 3:2:1:2 volume ratio and thoroughly mixed, then use 0.2% potassium permanganate solution to kill the substrate Sterilize the bacteria for 60 minutes, and place the cuttings after 2 days.

Embodiment 2

[0037] (1) Preparation of the nursery for the female parent: Plant seedlings in a field with a row spacing of 20×30cm, and plant seedlings for 3 years.

[0038] (2) Cutting time and place: Starting from June 1st, cuttings will be carried out in the greenhouse of Jiangsu Agriculture Expo Garden. The top of the greenhouse is covered by plastic film, and the plastic film is covered by double-layer shading nets. The light intensity is controlled to 50%, and the intermittent automatic is adopted. The spray device controls the relative humidity of the air at 80%, and uses the greenhouse water curtain system to ventilate and cool down to maintain the temperature at 28°C.

[0039] (3) Preparation of the cutting substrate: the cutting substrate is sandy soil: peat soil: garden soil: organic fertilizer = 4:4:2:3 volume ratio is fully mixed, then use 0.4% potassium permanganate solution to kill the substrate Sterilize the bacteria for 30 minutes, and then place the cuttings for 2 days.

Embodiment 3

[0045] (1) Preparation of the nursery for the female parent: Plant seedlings in a field with a row spacing of 20×30cm, and plant seedlings for 3 years.

[0046] (2) Cutting time and place: Cuttings will be carried out in the greenhouse of Jiangsu Agriculture Expo Garden on May 30. The top of the greenhouse is covered by plastic film, and the plastic film is covered with double-layer shading nets. The light intensity is controlled to 55% and the intermittent automatic is adopted. The spray device controls the relative humidity of the air at 75%, and uses the greenhouse water curtain system to ventilate and cool down to maintain the temperature at 25°C.

[0047] (3) Preparation of cutting substrate: The cutting substrate is sandy soil: peat soil: garden soil: organic fertilizer = 3.7:2.5:1.3:2.5 by volume ratio. After mixing well, use 0.3% potassium permanganate solution to destroy the substrate. Sterilize for 40 minutes, and place the cuttings after 2 days.

Abstract

The present application discloses a cutting propagation method for euonymus fortunei cv.gold. The method comprises the following steps of controlling the illumination intensity, the relative humidityand the temperature of a greenhouse in which adult seedlings are grown; preparing a cutting matrix which consists of sandy soil, peat soil, garden soil and organic fertilizer, sterilizing and disinfecting the matrix, and performing slip making on the adult seedlings to obtain prepared cutting slips, wherein the volume ratio of the sandy soil, the peat soil, the garden soil and the organic fertilizer is (0-4):(0-4):(1-5):(1-5); disinfecting base parts of the prepared cutting slips, soaking the base parts in a rooting agent, and performing cutting; and compacting the matrix around the cutting slips after cutting. After cutting management, the cutting propagation method for the euonymus fortunei cv.gold is convenient in material acquisition, short in seedling growing period, large in propagation coefficient, quick in growth and strong in resistance, the excellent characters of trees can be kept, the rooting rate of the cutting slips reaches 95.5% or above, and the number of adventitious roots reaches 9-12 roots/plant.

Description

Technical field [0001] The present invention relates to a plant propagation method, in particular to a cutting propagation method of Euonymus euphorbiae. Background technique [0002] Euonymus fortunei (Euonymus fortunei cv.Gold) is an evergreen broad-leaved shrub belonging to Euonymus fortunei. It is mainly born under mixed woods in the mountains, forest margins or shrubs. It is distributed from various provinces in the lower reaches of the Yangtze River to Jilin, and cultivated in many places. Euonymus euonymus has unique branches and wings. The leaves are golden in the growing season and red in the dormant season. The plant height is 30-50cm, the crown width is 60-80cm, the crown is low, the stems and branches are strong, and the management is extensive. Gardens are mostly used for garden greening, and can also be planted next to rockery as a matching plant or as a foundation planting and model flower bed. With the increasing demand for the golden leaf euonymus, the breeding...
