Problems solved by technology

h 2 o 2 Used to destroy germination inhibitory substances, 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 cold and drought, due to GA 3 The overgrowth brought about will increase the damage of the seedlings and cause the death of the seedlings. The above reasons limit the application of sassafras seeds, only limited to the field of laboratory research

Embodiment 1

[0030] 2.3 The simple soaking liquid group is the scheme of embodiment 1:

[0031] (1) Seed soaking treatment: apply a seed soaking solution at a temperature of 30°C, and soak the seeds for 1 hour;

[0032] (2) Germination acceleration treatment: cover the sassafras seed straw obtained in step (1) to keep warm and accelerate germination, keep the temperature at 20°C and humidity at 40%, and store for 5 days.

[0033] 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, 15mg of polyoxyethylene polyoxypropanolamine ether, 40mg of γ-aminobutyric acid, and 0.2g of astaxanthin into 1000ml of distilled water to make a suspension.

Embodiment 2

[0034] 2.4 optimized treatment+soaking liquid group is embodiment 2 scheme:

[0035](1) Seed soaking treatment: add seed soaking liquid, and apply the soaking liquid to soak the pretreated seeds for 2 hours;

[0036] (2) Oscillation decompression treatment: Put the sassafras seeds obtained in step (1) into a sealed constant temperature water bath culture oscillator, pump out part of the air, reduce the air pressure until the air pressure is 0.07Mpa, start the oscillation treatment, and the oscillation treatment temperature 30°C, shaking speed 20r / min, time 0.5h, open the air valve to fully ventilate, keep shaking for 12h;

[0037] (3) Acceleration treatment: wash the sassafras seeds obtained in step (2) with water at 15°C, and dry naturally, cover with straw to keep warm and accelerate germination, keep the temperature at 20°C, and keep the humidity at 40%, and store for 5 days.

[0038] The composition and preparation method of the seed soaking solution are: mix NaCl 0.6g, K...

Abstract

The invention discloses a special seed soaking agent for Sassafras tsumu, and belongs to the tree cultivation field. The seed soaking agent is characterized in that the liquid seed soaking agent for Sassafras tsumu si prepared by adding 0.6 of NaCl, 0.98g of KCl, 0.17g of CaCl2.2H2O, 0.11g of MgCl2.6H2O, 15mg of polyoxyethylene polyoxypropylene ether, 40mg of gamma-aminobutyric acid and 0.2g of astaxanthin to 1000ml of distilled water to prepare a suspension. Compared with seed soaking agents in the prior art, the liquid seed soaking agent can promote the germination of Sassafras tsumu seeds, so a high germination percentage can be obtained.

Description

technical field [0001] The invention relates to a seed soaking agent, in particular to a special seed soaking agent suitable for sassafras, which can be used for cultivation in a low temperature environment and for the germination of new seeds. Background technique [0002] Sassafras tsumu (Sassafras tsumu) is a plant of the genus Sassafras in Lauraceae. It grows fast and has good material, and its roots, stems, and leaves can be used as medicine to treat rheumatism, lumbar muscle strain, sprained tendons, and stomach problems; its seeds contain 30 % Zinc oil, used in the manufacture of paints. [0003] Sassafras is mainly propagated by seeds, and it can also be propagated by roots, but the requirements for temperature and humidity are high and the yield of seedlings is low. Sassafras seeds have the characteristics of long dormancy period, irregular germination, and it takes 2 to 3 years to fully germinate and unearth. Due to the long dormancy period of the seeds, most of ...
