Cutting propagation method of magnolia denudata

Abstract

The invention discloses a cutting propagation method of magnolia denudate. The cutting propagation method comprises the following steps of 1, seedbed building, wherein (1), the root of kudzu vine, sugarcane bagasse, a glass fiber cutting yarn and hydrophilic non-woven fabrics which are subject to high temperature sterilization are taken, smashed, sieved and mixed evenly according to a specific proportion to obtain a seedbed substrate; (2), the seedbed substrate is laid, the temperature is controlled at 24-25 DEG C, the humidity is controlled at 90-92% RH, and balance is carried out; 2, treatment of cuttings, wherein (1), from late spring to early summer, semi-lignified branches are selected as cutting slips and washed with water and 0.05-0.08wt% of sodium bicarbonate aqueous solution and water; (2), the lower ends of the cutting slips are cut into an inclined mouth shape, the lower portions of the cutting slips are placed into specially-prepared regulating fluid and 0.60-0.66wt% of indolebutyric acid aqueous solution to be soaked; (3), after soaking is completed, corn oil is quickly applied outside the cutting slips; 3, seedbed management, wherein (1), the cutting slips are inserted into the seedbed, and the depth of the cutting slips is 4-5 centimeters; (2), plant ashes are paved on the seedbed; (3), temperature and humidity are kept. The cutting propagation method of the magnolia denudate has the advantages of improving the survival rate.

Description

technical field

[0001] The invention relates to a cutting propagation method of Magnolia magnolia. Background technique

[0002] Magnolia magnolia (formal name used at school Magnolia denudata Desr) is Magnoliaceae Magnolia plant, has another name called Magnolia magnolia, originates in China's Yangtze River Basin, and there are wild places such as Lushan Mountain, Mount Huangshan, Emei Mountain, etc., and existing Beijing and the south of Yellow River Basin all have cultivation. Magnolia has strong resistance to harmful gases, has certain resistance to sulfur dioxide and chlorine, and has the ability to absorb sulfur. Therefore, Magnolia is a good anti-pollution greening variety in air-polluted areas.

[0003] There are mainly two methods of propagation of magnolia: seed propagation and cutting propagation. The application publication number is CN106550689A, and the Chinese patent with the application publication date on April 5, 2017 discloses a method for raising seedlin...

Embodiment 1

[0029] Embodiment 1: a kind of cutting propagation method of Magnolia Magnolia, comprises the following steps:

[0030] (1) Seedbed construction:

[0031] ① Pueraria root, bagasse, glass fiber cut yarn and hydrophilic non-woven fabric were taken and pulverized respectively after being sterilized at 80°C, passed through a 50-mesh sieve respectively, and pueraria root, bagasse, glass fiber cut yarn and hydrophilic non-woven fabric were respectively crushed. The woven cloth is mixed uniformly according to the mass ratio of 1:0.72:0.24:0.12 to obtain the seedbed matrix;

[0032] ② Lay the seedbed substrate to a thickness of 8 cm, adjust the ambient temperature to 24°C, adjust the ambient relative humidity to 90% RH, and perform subsequent cutting work after balancing for 8 days;

[0033] (2) Cutting treatment:

[0034] 1. Select semi-lignified branches as cuttings from late spring to early summer, and clean the cuttings with water, 0.05wt% sodium bicarbonate aqueous solution and...
