Embodiment 1

[0029] A kind of propagation method of spirea pearl, comprising the following steps:

[0030] Step A. Select the young twigs of Spiraea pearls as the cutting material, and spray 80% 500 times solution of Zinc wettable powder on Spiraea pearls every 5 days in late May, and the time is from 8:00 to 10:00 p.m. point, last for half a month;

[0031] Step B. Prepare the cutting matrix: the cutting matrix is ​​composed of perlite and peat in a volume ratio of 1:4, spread evenly in the plug tray, and spray 700 times solution of 70% thiophanate-methyl powder to the cutting matrix before cutting As a disinfectant, ensure that the matrix is ​​covered with plastic wrap for 7 days after pouring;

[0032] Step C. Collect Spiraea fringae with a thickness of 0.2-0.4cm in the first ten days of June. Ear picking should be carried out on cloudy or sunny mornings when the dew is not dry. Middle; Before and during ear picking, the tools such as branch shears should be disinfected, and the disin...

Embodiment 2

[0039] A kind of propagation method of spirea pearl, comprising the following steps:

[0040] Step A. Select the young twigs of Spiraea pearls as the cutting material. Spray Spiraea pearls with 80% 800-fold solution of Zinc wettable powder every 5 days from late May at 8:00 p.m. to 10:00 p.m. point, last for half a month;

[0041] Step B. Prepare the cutting matrix: the cutting matrix is ​​composed of perlite and peat in a volume ratio of 1:4, spread evenly in the hole tray, and spray 70% thiophanate-methyl powder 1000 times solution on the cutting matrix before cutting As a disinfectant, ensure that the matrix is ​​covered with plastic wrap for 10 days after pouring;

[0042] Step C. Collect Spiraea fringae with a thickness of 0.2-0.4cm in the first ten days of June. Ear picking should be carried out on cloudy or sunny mornings when the dew is not dry. Middle; Before and during ear picking, the tools such as branch shears should be disinfected, and the disinfection can be s...

Embodiment 3

[0049] This embodiment is roughly the same as Example 1, and the similarities will not be repeated. The difference is that in step E, the cuttings are divided into 16 groups on average, with 5 cuttings in each group, and different rooting soaks are carried out for each group of cuttings, and then The same follow-up treatment, the rooting rate and the average rooting number after the cutting were counted in 22 days after cutting, and the transplanting survival rate was counted in 10 days after transplanting. The content relationship between IAA and IBA is shown in Table 1.

[0050] Table 1. Treatment and results of different hormone combinations for cuttings

[0051]

[0052] figure 1 It is a comparison between the randomly selected cuttings of the 5th group and the 9th group when transplanting. It can be seen from the figure that the branches and leaves of the 5th group (left) are more bulky than the 9th group (right), and the number of roots is larger. many.

Abstract

The invention belongs to the field of plant propagation, and particularly relates to a propagation mehtod of spiraea thunbergii. The propagation method comprises the following steps: selecting annualtender twigs of the spiraea thunbergii as a cuttage material, and carrying out sterilization treatment on the spiraea thunbergii 15 days before material collection; spraying a disinfectant to a cuttage matrix, covering the matrix with films after watering the matrix thoroughly, cutting off base lignified branches of collected spiraea thunbergii scions, selecting middle branches and tender tip branches, and cutting the branches into cuttings; disinfecting the cuttings with a 0.1% potassium permanganate solution, washing the disinfected cuttings with clear water, and soaking the washed cuttingswith a rooting agent in a dark place after drying the cuttings in the shade; after conducting cuttage of the cuttings into the matrix, compacting and watering the matrix; and spraying a 5% potassium permanganate solution once every 5-7 d after cuttage until rooting. A cuttage technology is applied to the spiraea thunbergii, plants are ensured to stably retain characters of stock plants after propagation, the cuttage survival rate is high, and meanwhile, the cultivation time is shortened.

Description

technical field [0001] The invention belongs to the field of plant propagation, and in particular relates to a method for propagating spirea pearls. Background technique [0002] Pearl Spiraea (Spiraea thunbergii Bl.), Rosaceae, Spiraea shrubs, up to 1.5 meters high. The flowering period is early, the flowers bloom densely like snow, white and clean, and the leaves are as thin as feathers. It has a very high ornamental value. Born in moist and well-drained soil, easy cultivation and management. Spiraea pearl is a good choice for flower glasses and flower belts, and its excellent characteristics can also create commercial value as fresh cut flowers. [0003] However, currently in the south, Spiraea pearl has not been fully applied in landscaping. The most common propagation method is sowing, but sowing and breeding also has its limitations, such as long cycle, difficult seed collection, low survival rate, etc. , Bai Yuying et al. (Bai Yuying, Guo Yongsheng. Pearl Spiraea b...
