Problems solved by technology

However, the above scheme still has the following defects: ① GA 3 (Gibberellin) is the most widely used plant growth regulator in agriculture, forestry and horticulture in my country. It is mainly used to promote the growth and development of crops, mature early, increase yield and break the dormancy of seeds, tubers, bulbs and other organs. , but the main function of gibberellin is to promote cell elongation, thereby causing stem elongation and plant height, when using GA 3 If there are unfavorable climatic conditions such as drought, due to GA 3 The overgrowth brought about will aggravate the injury of the seedlings and cause the death of the seedlings. The above reasons limit the application of Cyclocarya paliurus seeds, and are only limited to the field of laboratory research; Problems such as difficulty in effectively and substantially improving the genetics, breeding, and production of Cyclocarya paliurus are lim...

Embodiment 1

[0027] 2.2 The lye treatment group is the scheme of Example 1:

[0028] (1) Seed soaking treatment: Add 1N NaOH solution dropwise to 1000ml of clean water to adjust the pH value of the solution to 8.6 and the temperature to 30°C, and use the lye to soak the pretreated seeds for 9h;

[0029] (2) Germination treatment: Clean the Cyclocarya seed obtained in step (1) with 15°C water and dry naturally. Cover the straw for heat preservation and accelerate germination. Keep the temperature at 20°C and humidity at 60% for 8 days.

Embodiment 2

[0030] 2.3 The optimization processing group is the solution of embodiment 2:

[0031] (1) Alkalizing seed soaking treatment: Add 1N NaOH solution dropwise to 1000ml of clean water to adjust the pH value of the solution to 8.6, and use the lye to soak the pretreated seeds for 9h;

[0032] (2) Oscillation and decompression nitrogen enrichment treatment: Put the Cyclocarya sylvestris seeds obtained in step (1) into a sealed constant temperature water bath culture oscillator, extract part of the air, add nitrogen, and reduce the air pressure to reach an air pressure of 0.07MPa, nitrogen When the content is 85%, start the oscillation treatment, the oscillation treatment temperature is 30℃, the oscillation speed is 20r / min, and the time is 0.5h. Open the air valve to fully ventilate until the gas in the oscillator is atmospheric air and keep the oscillation for 12h;

[0033] (3) Germination treatment: Wash the Cyclocarya seed obtained in step (2) with 15°C water and dry naturally. Cover...

Embodiment 3

[0034] 2.4 The simple seed soaking solution group is the scheme of Example 3:

[0035] (1) Seed soaking treatment: apply seed soaking liquid at a temperature of 30℃ for 9h;

[0036] (2) Germination treatment: Cover the straw of Cyclocarya serrata seed obtained in step (1) for heat preservation and germinate, keep the temperature at 20°C, and the humidity at 60% for 8 days.

[0037] The composition and preparation method of the seed soaking solution are: NaCl 0.6g, KCl 0.98g, CaCl 2 ·2H 2 O 0.17g, MgCl 2 ·6H 2 0.11 g of O, 30 mg of alkyl alcohol polyoxyethylene methacrylate, 40 mg of γ-aminobutyric acid, and 0.2 g of astaxanthin were added to 1000 ml of distilled water to prepare a suspension.

Abstract

The invention discloses a seed soaking agent for promoting the germination of Folium Cylocaryae Paliuri seeds, and belongs to the tree breeding field. The seed soaking agent is characterized in that the liquid seed soaking agent is prepared by adding 0.6g of NaCl, 0.98g of KCl, 0.17g of CaCl2.2H2O, 0.11g of MgCl2.6H2O, 30-40mg of poly(ethyleneglycol)alkylmethacrylate, 40mg of gamma-aminobutyric acid and 0.2g of astaxanthin to 1000ml of distilled water. Compared with seed soaking agents in the prior art, the seed soaking agent in the invention can promote the germination of the Folium Cylocaryae Paliuri seeds, so a high germination percentage is obtained, and a high seedling survival rate can be obtained at a low temperature.

Description

Technical field [0001] The present invention relates to a seed soaking agent, in particular to a seed soaking agent for promoting the germination of Cyclocarya paliurus seeds, which can be used for low-temperature environment cultivation and the germination of new seeds. Background technique [0002] Cyclocarya paliurus Iljin. (Cyclocarya paliurus Iljin.) is a unique single-species tree plant in my country. It is one of the endangered plants under national key protection and belongs to three types of protected plants. The green willow tree species has a wide range of uses and is a precious tree species with great development and development prospects. Studies have found that Cymbidium morifolium leaves not only contain macro elements such as potassium, calcium, magnesium, and phosphorus, which are necessary for the human body, but also trace elements that are important for human health, such as manganese, iron, copper, zinc, selenium, chromium, and alum. , Germanium, etc.; Cyclo...
