Problems solved by technology

[0003] The common propagation method of hackberry is the seeding method. However, due to the separation of traits among the offspring, the seedlings cannot obtain products with the same quality as the female parent. Therefore, the disease resistance of the seedlings varies, and they are easy to be infected by diseases.
The traditional method of spraying chemical agents to sterilize seedlings for disease control is harmful to the human body and not conducive to the growth of seedlings

Embodiment 1

[0017] A method for improving the disease resistance of hackberry seedlings, specifically comprising the following steps:

[0018] (1) Seedling environmental control

[0019] After raising seedlings in spring every year, when the seedlings grow to a seedling height of 50-60cm, raise the ambient temperature in the nursery greenhouse to 22°C and reduce the humidity in the shed to below 30% for 8 consecutive days, and increase the light for 3 hours every night. 900lx, keep the leaves dry, can prevent the growth of germs on the leaves, and at the same time can effectively enhance the metabolic intensity and photosynthesis intensity of the seedling plant cells, accumulate more energy, and prepare for the subsequent operation;

[0020] (2) Bacterial solution preparation

[0021] Collect the diseased leaves of hackberry that have just been infected with powdery mildew, coal stain, etc., cut them into pieces and put them in a container, add 2% glucose solution of 1 times the mass of ...

Embodiment 2

[0026] A method for improving the disease resistance of hackberry seedlings, specifically comprising the following steps:

[0027] (1) Seedling environmental control

[0028] After raising seedlings in spring every year, when the seedlings grow to a seedling height of 50-60cm, raise the ambient temperature in the nursery greenhouse to 25°C and reduce the humidity in the shed to below 30% for 9 consecutive days, and increase the light for 4 hours every night. 1000lx, keep the leaf surface dry, prevent the growth of germs on the leaf surface, and at the same time effectively enhance the metabolic intensity and photosynthesis intensity of the seedling plant cells, accumulate more energy, and prepare for the subsequent operation;

[0029] (2) Bacterial solution preparation

[0030] Collect the diseased leaves of hackberry that have just been infected with powdery mildew, sooty mildew, etc., cut them into pieces and put them in a container, add 2% glucose solution of 1 times the m...

Abstract

The invention relates to a method for improving disease resistance of hackberry seedling plants. The method specifically comprises the following steps: (1) controlling environments of young seedlings; (2) preparing a bacterial solution; (3) treating seedling plants; (4) transplanting the seedling plants outdoors when the height of each seedling plant is 70cm to 80cm. Proven by experiments, the disease resistance of the hackberry seedling plants treated by using the method for improving the disease resistance of hackberry trees, provided by the invention, is remarkably improved, the disease incidence rate in 3 months after seedling plants without any treatment are transplanted outdoors reaches up to 28.6%, and the disease incidence rate of the treated seedling plants is decreased to 11.1% or less, so that the effect is remarkable, the consumption of disease control agents is effectively lowered, the method is quite beneficial to the early stage of growth of young seedlings of the hackberry trees, and the quality of the hackberry seedling plants is higher.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a method for improving the disease resistance of hackberry seedlings. Background technique [0002] Hackberry, Ulmaceae Hackberry is a deciduous tree with smooth, gray bark; Hackberry is mostly born in shade-tolerant plains, and is light-loving, suitable for warm and humid climates, and suitable for fertile and flat land. It does not have strict requirements on the soil, has a certain ability to tolerate drought, is also resistant to water, humidity and poor soil, and has strong adaptability. It is an excellent garden tree species. [0003] The common propagation method of Hackberry is the seeding method. However, due to the separation of traits among the offspring, the seedlings cannot obtain products with the same quality as the female parent. Therefore, the disease resistance of the seedlings varies, and they are easy to be infected by diseases. The traditional m...
