Embodiment Construction

[0021] A kind of Lagerstroemia indica cutting seedling raising method of the present invention comprises the following steps:

[0022] (1) Selection of cutting medium and erection of sunshade net

[0023] The cuttings of crape myrtle are carried out in greenhouses, and the requirements for the cutting medium are loose, permeable, breathable, free of weeds and germs. Usually the medium is more or less with pests and diseases, choose yellow heart soil as the cultivation substrate, add water to make the medium moist, and then add 500 times of Dikesong solution for disinfection

[0024] Set up a sunshade net above the seedbed from May to June. The refractive index of the sunshade net is guaranteed to be 75%; each net should be connected with cloth strips or thin wires to ensure that large pieces of sunlight do not directly hit the seedbed. so as not to burn the seedlings.

[0025] (2) Plug cuttings in summer

[0026] Cuttings are carried out from late June to early July, and st...

Abstract

The invention discloses a cuttage seedling culture method for red lagerstroemia speciosa and belongs to the field of seedling propagation culture. The method comprises the following steps that (1) treated yellow soil is adopted as culture substrates, and a sunshade net is erected above a seedling bed in May to June; (2) the cuttage is carried out in late June to early July, strong branches are adopted as cutting slips, grading is carried out, and the tray cuttage is carried out after the treatment by a rooting agent; (3) films are mulched after the cuttage, the temperature is controlled to be 25 to 28 DEG C, the humidity reaches 90 to 100 percent, and the pest disease prevention, treatment and management are carried out; and (4) the ventilation and the seedling exercising are gradually carried out after 20 days from the cuttage according to the rooting conditions. The method aims at the characteristics of the red lagerstroemia speciosa, greenhouse facilities and tray containers are utilized for summer cuttage seedling culture, the mass propagation and culture of the red lagerstroemia speciosa can be realized, qualified seedlings are provided for markets, meanwhile, the rooting rate and the survival rate of the red lagerstroemia speciosa are greatly improved. When the method provided by the invention is used for cuttage, the branches in the current year can grow to about 60 to 80cm, and the survival rate reaches higher than 95 percent.

Description

technical field [0001] The invention relates to the field of plant cultivation and breeding, in particular to a method for raising seedlings of red leaf crape myrtle cuttings. Background technique [0002] Lagerstroemia indica, also known as hundred day red, full house red. It is a dicotyledonous plant of the genus Lagerstroemia in the genus Lagerstroemia. Native to southern Asia and northern Australia. It is distributed in East China, Central China, South China and Southwest China, and is widely cultivated in various places.
