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 limited; ③ Cyclocarya paliurus is mainly distributed in Anhui, Jiangsu, Zhejiang, Jiangxi, Fujian and other places, and there is no growth in Shandong, and the reason is mostly due to Germination and seedling stages, seed germination and early seedling growth are sensitive periods to adversity, with low resistance
However, if the temperature of germination and seedling growth is accommodated and the sowing is postponed until mid-April when the temperature is suitable, the height of the seedlings has not reached 10cm, and it has entered summer at this time, with high temperature and hot weather, accompanied by summer drought, low air humidity, and groundwater. The position is high and the soil drainage performance is poor, which will easily cause the seedlings to fail to survive the summer and lead to death. Even if the seedlings are treated with shade, the seedlings will survive safely, but the growth will be slow or even stagnant

Embodiment 1

[0027]2.2 lye treatment group is embodiment 1 scheme:

[0028] (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;

[0029] (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

[0030] 2.3 optimized treatment group is embodiment 2 scheme:

[0031] (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;

[0032] (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;

[0033] (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

[0034] 2.4 The simple soaking liquid group is the scheme of embodiment 3:

[0035] (1) Seed soaking treatment: apply a seed soaking solution at a temperature of 30°C, and soak the seeds for 9 hours;

[0036] (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.

[0037] The composition and preparation method of the soaking solution are: mix NaCl0.6g, KCl0.98g, CaCl 2 2H 2 O0.17g, MgCl 2 ·6H 2 O0.11g, 30mg of alkyl alcohol polyoxyethylene methacrylate, 40mg of γ-aminobutyric acid, and 0.2g of astaxanthin were added to 1000ml of distilled water to make a suspension.

Abstract

The present invention discloses a method for promoting germination of tree seeds, and belongs to the field of tree proliferation. The method comprises the following steps of: (1) seed soaking treatment: soaking seeds for 9 h by using seed soaking liquid at the temperature of 30 DEG C; wherein a preparation method of the soaking liquid with the following components comprises: adding 0.6 g of NaCl, 0.98 g of KCl, 0.17 g of CaCl2.2H2O, 0.11 g of MgCl2.6H2O, 30 mg of methylacrylic acid alkyl alcohol polyoxyethylene ester, 40 mg of gamma-aminobutyric acid, and 0.2 g of asta-xanthin into 1000 ml of distilled water to obtain a suspension; and (2) germination treatment: covering the cyclocarya paliurus seed obtained in the step (1) with straws, insulating and germinating, keeping the temperature at 20 DEG C and humidity at 60%, and storing for eight days. Compared with the prior art, the method for promoting germination of tree seeds can promote germination of the cyclocarya paliurus seeds, so that a higher germination rate is obtained, and a higher seedling survival rate can be obtained at a relatively low temperature.

Description

technical field [0001] The present invention is a divisional application of the invention patent application "A Seed Soaking Agent for Promoting Germination of Cyclocarya paliurus Seeds" (Application No.: 2013104708274), which relates to a seed soaking agent, especially a method for promoting seed germination of trees, which can be used for Cultivation in low temperature environment, and germination of new seeds. 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 healt...
