Embodiment 1

[0025] In March 2014, the researchers conducted a seedling experiment on hard branch cuttings of Lagerstroemia crape myrtle in Jiangsu Agriculture and Forestry Vocational and Technical College, and selected (1) Three levels of A factors of crape myrtle branches in Red Fireball: A 1 Lignified branches of the current year; A 2 2-year-old lignified branches; A 3 Three-year-old lignified branches. (2) The type of rooting agent B factor three levels: B 1 ABT2 (ABT2 rooting powder is generally used for easy rooting plants, developed by Professor Wang Tao, an academician of the Chinese Academy of Engineering) B 2 NAA; B 3 IBA. (3) Three levels of cutting matrix C factor: C1 yellow heart soil; C2, yellow heart soil: perlite: vermiculite volume ratio = 1:1:1; C3, peat soil: perlite: vermiculite volume ratio is 1:1: 1. Orthogonal experiments with three factors and three levels were carried out, and the cuttings were dipped in the medium speed of 1200mg / L solution for 5 seconds in ...

Embodiment 2

[0028] Utilize the method of the present invention to red fireball crape myrtle hard branch cutting propagation, mainly comprise the following steps:

[0029] (1) Prepare seedling raising facilities in early March: mainly including building simple greenhouses, seedbeds and seedbed substrates. The seedbed substrates are mixed evenly at the volume ratio of yellow core soil: perlite: vermiculite = 1:1:1. Three days before cutting, use Spray the bed surface with 500 times carbendazim disinfectant to moisten the matrix.

[0030] (2) Rooting agent preparation: ABT No. 2 rooting agent is prepared at a concentration of 1200mg / L. The preparation method is: first put 1 packet of ABT No. 2 rooting agent into a non-metallic container, then add 100-150ml of alcohol, and stir while adding. After the ABT rooting powder is fully dissolved, add water to dilute to the required concentration. spare.

[0031] (3) Production of cuttings: In mid-March, select 1-year-old robust branches free of di...

Abstract

The invention discloses a hard-wood cutting seedling method for Lagerstroemia indica Dynamite, and belongs to the field of seedling propagation. The method comprises the following steps: 1, preparing a seedbed and a cutting medium; 2, preparing a rooting agent; 3, making cutting slips; 4, cutting; 5, performing management after cutting and transplanting. Compared with the cutting seedling cost of the existing cutting seedling method for lagerstroemia indica, the cutting seedling cost of the hard-wood cutting seedling method for the Lagerstroemia indica Dynamite, disclosed by the invention, is reduced by 30 percent to 40 percent; the method has the advantages of being low in cost, simple in management, easy in operation, easy to popularize and the like; healthy seedlings cultured in the current year by the hard-wood cutting seedling method for the Lagerstroemia indica Dynamite, disclosed by the invention, can reach more than 60cm.

Description

technical field [0001] The invention relates to a method for asexual propagation of trees, in particular to a method for raising seedlings of red fireball crape myrtle with high hard branch cuttings. Background technique [0002] Red fireball crape myrtle ( Lagerstroemia indica 'Dynamite') is a small deciduous tree with a height of 8-10m and a crown width of 10-12m. It is a new variety of Lagerstroemia genus Lagerstroemia in the family Cerataceae, which was selected and bred by American horticulturalists after more than 40 years of dedicated research. Leaf color changes (new leaves are dark red, old leaves are green), flower color is fresh (flowers are often bright red, scarlet in sunny and hot days, bright red with white edges in cloudy and cool days), long flowering period (initial flowering in July, flowering period up to 4 months), resistance to pruning (timely pruning after flowering can bloom multiple times) and low temperature resistance (ability to -23 o C low temp...
