Problems solved by technology

But this method treats the symptoms but not the root cause. Magnolia magnolia tree is tall, and diseased leaves are not easy to be found in time. Anthracnose is easy to infect, which seriously affects the appearance of Magnolia magnolia tree and greatly increases the maintenance cost of Magnolia magnolia tree.

Embodiment 1

[0019] A kind of cutting seedling raising method that reduces the anthracnose incidence rate of Magnolia magnolia, specifically the following steps:

[0020] (1) Selection of high-quality cuttings

[0021] According to the statistics, select Magnolia magnolia tree with excellent properties and low incidence of anthracnose as the female parent, and cut suitable branches as cuttings. Pass low-frequency alternating current into it for 15 seconds every 15 minutes;

[0022] (2) Callus treatment

[0023] Use the normal temperature nutrient solution for hydroponics of the treated cuttings. After the callus of the cuttings is formed, make a second wound on the callus of the cuttings, and raise the temperature of the nutrient solution for hydroponics to 35-40°C. Add 3 hours of light every day, and continue to cultivate until the callus is formed twice and differentiates into roots;

[0024] (3) Treatment after rooting of cuttings

[0025] After the cuttings take root, transfer to t...

Embodiment 2

[0030] A kind of cutting seedling raising method that reduces the anthracnose incidence rate of Magnolia magnolia, specifically the following steps:

[0031] (1) Selection of high-quality cuttings

[0032] According to the statistics, select Magnolia magnolia tree with excellent properties and low incidence of anthracnose as the female parent, and cut suitable branches as cuttings. Pass low-frequency alternating current to it for 30 seconds every 15 minutes;

[0033] (2) Callus treatment

[0034] Use the normal temperature nutrient solution for hydroponics of the treated cuttings. After the callus of the cuttings is formed, make a second wound on the callus of the cuttings, and raise the temperature of the nutrient solution for hydroponics to 35-40°C. Add 5 hours of light every day, and continue to cultivate until the callus forms secondary and differentiates into roots;

[0035] (3) Treatment after rooting of cuttings

[0036] After the cuttings take root, transfer to the...

Embodiment 3

[0041] A kind of cutting seedling raising method that reduces the anthracnose incidence rate of Magnolia magnolia, specifically the following steps:

[0042] (1) Selection of high-quality cuttings

[0043] According to the statistics, select Magnolia magnolia tree with excellent properties and low incidence of anthracnose as the female parent, and cut suitable branches as cuttings. Pass low-frequency alternating current into it for 20 seconds every 15 minutes;

[0044] (2) Callus treatment

[0045] Use the normal temperature nutrient solution for hydroponics of the treated cuttings. After the callus of the cuttings is formed, make a second wound on the callus of the cuttings, and raise the temperature of the nutrient solution for hydroponics to 35-40°C. Add 4 hours of light every day, and continue to cultivate until the callus is formed twice and differentiates into roots;

[0046] (3) Treatment after rooting of cuttings

Abstract

The invention relates to a cutting seedling-raising method for reducing magnolia grandiflora anthracnose incidence rate. The cutting seedling-raising method particularly includes the steps: (1) high-quality cutting selection; (2) callus tissue treatment; (3) cutting rooting post-treatment. After experiments, the method is used for cutting seedling-raising of magnolia grandiflora, and the incidence rate of anthracnose is reduced from 35.5% in the prior art to 13.6% or less within 6 months before cutting seedling-raising, so that the method has a remarkable effect on improvement of the anthracnose resistance on the magnolia grandiflora.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a method for raising seedlings by cuttings for reducing the incidence of anthracnose of Magnolia magnolia. Background technique [0002] Magnolia magnolia is a plant of the family Magnoliaceae and the genus Magnolia. It is native to the Americas, North America, and the Yangtze River Basin in mainland China and the areas south of it. Magnolia Magnolia is also known as "Lotus Magnolia" because of its large blooms and lotus-like shape. Magnolia Magnolia has a majestic posture, broad leaves and thick shade, flowers like lotus and fragrant fragrance. It is a beautifying tree species, resistant to smoke and wind, and toxic gases such as sulfur dioxide It has strong resistance and can be used to purify the air and protect the environment. It is an excellent tree species for landscaping. [0003] The most common disease of Magnolia magnolia is anthracnose, which usually occ...
