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 limite

Embodiment 1

[0030] 2.2 lye treatment group is embodiment 1 scheme:

[0031] (1) Seed soaking treatment: Add 1N NaOH solution dropwise to 1000ml of clear water to adjust the pH value of the solution to 8.6, and the temperature is 30°C, and soak the pretreated seeds with the lye for 9 hours;

[0032] (2) Acceleration treatment: wash the Cyclocarya paliurus seeds obtained in step (1) with clean water at 15°C and dry naturally, cover them with straw to keep them warm and accelerate germination, keep the temperature at 20°C and humidity at 60%, and store for 8 days.

Embodiment 2

[0033] 2.3 optimized treatment group is embodiment 2 scheme:

[0034] (1) Alkalized seed soaking treatment: Add dropwise NaOH solution with a concentration of 1N in 1000ml of clear water to adjust the pH value of the solution to 8.6, and soak the pretreated seeds in the lye for 9 hours;

[0035] (2) Oscillating decompression and nitrogen-enriching treatment: put the Cyclocarya paliurus seeds obtained in step (1) into a sealed constant temperature water bath culture shaker, pump out part of the air, add nitrogen, and reduce the air pressure until the air pressure is 0.07MPa. When the content is 85%, start the shaking treatment, the shaking treatment temperature is 30°C, the shaking speed is 20r / min, the time is 0.5h, open the air valve to fully ventilate, until the gas in the shaker is air at normal pressure, keep shaking for 12h;

[0036] (3) Acceleration treatment: wash the Cyclocarya paliurus seeds obtained in step (2) with clean water at 15°C, and dry them naturally, cover ...

Embodiment 3

[0037] 2.4 The simple soaking liquid group is the scheme of embodiment 3:

[0038] (1) Seed soaking treatment: apply a seed soaking solution at a temperature of 30°C, and soak the seeds for 9 hours;

[0039] (2) Acceleration treatment: cover the Cyclocarya paliurus seeds obtained in step (1) with rice straw for heat preservation, keep the temperature at 20°C, and keep the humidity at 60%, and store for 8 days.

[0040] The composition and preparation method of the seed soaking solution are: mix NaCl 0.6g, KCl 0.98g, CaCl 2 2H 2 O 0.17g, MgCl 2 ·6H 2 Add 0.11g of O, 30mg of alkyl alcohol polyoxyethylene methacrylate, 40mg of γ-aminobutyric acid, and 0.2g of astaxanthin to 1000ml of distilled water to make a suspension

Abstract

The invention discloses a method for improving the germination percentage of Cyclocarya paliurus seeds, and belongs to the tree breeding field. The method is characterized in that the method comprises the steps of alkalization seed soaking treatment, oscillation pressure-reduction nitrogen-enriched treatment and germination accelerating treatment. Compared with the prior art, the method has the advantages of promotion of the germination of the Cyclocarya paliurus seeds, high germination percentage, and high seedling survival rate at low temperatures.

Description

technical field [0001] The invention relates to a method for promoting germination of seeds, in particular to a method for promoting germination of Cyclocarya paliurus seeds suitable for planting and cultivating in Shandong area. Background technique [0002] Cyclocarya paliurus Iljin. is a unique single-species arbor plant in my country. It is one of the endangered plants under national key protection and belongs to the third category of protected plants. Cyclocarya paliurus is widely used, and it is a precious tree species with great prospects for development and utilization. Studies have found that Cyclocarya paliurus leaves not only contain essential elements such as potassium, calcium, magnesium, and phosphorus, but also contain trace elements that play an important role in human health, such as manganese, iron, copper, zinc, selenium, chromium, and alum. , germanium, etc.; Cyclocarioside I (cyclocarioside I) extracted from the leaves of Cyclocarya paliurus is one of t...
