Problems solved by technology

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
[0003] Therefore, low temperature and seedling disease have become the restrictive conditions for the adaptive introduction of sassafras production in Shandong, which limits the further development of sassafras industry
However, in production, the germination rate of sassafras is not high, and the irregular emergence has also become the key to limit the development of sassafras industry.

Embodiment 1

[0028] 2.3 optimized treatment + seed soaking solution group is the scheme of embodiment 1:

[0029] (1) Seed soaking treatment: add seed soaking liquid, and apply the soaking liquid to soak the pretreated seeds for 2 hours;

[0030] (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;

[0031] (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.

[0032] The composition and preparation method of the seed soaking solution are:...

Embodiment 2

[0056] 2.3 optimized treatment + seed soaking solution group is the scheme of embodiment 2:

[0057] (1) Seed soaking treatment: add seed soaking liquid, and apply the soaking liquid to soak the pretreated seeds for 2 hours;

[0058] (2) Oscillation and decompression treatment: Put the sassafras 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 to reach an air pressure of 0.06Mpa and a nitrogen content of 85 %, start the shaking treatment, the shaking treatment temperature is 40°C, the shaking speed is 15r / min, the time is 0.5h, open the air valve to fully ventilate, and keep shaking for 12h;

[0059] (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.

Abstract

The invention discloses a Sassafras tsumu seed dormancy breaking and germination accelerating method suitable for the Shandong region, and belongs to the tree planting field. The method is characterized in that the method comprises the steps of seed soaking treatment, oscillation pressure reduction treatment and germination accelerating treatment; and a seed soaking liquid is prepared by adding 0.6g 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 solution. Compared with the prior art, the method has the advantages of acceleration of the Sassafras tsumu seed germination, improvement of the cold resistance of seedlings, and enhancement of the adaptation of Sassafras tsumu seeds to poor surroundings, so a high germination percentage and a high seedling survival rate can be obtained.

Description

technical field [0001] The invention relates to a method for treating tree seeds, in particular to a method for relieving dormancy and accelerating germination of sassafras seeds in Shandong area. Background technique [0002] Sassafras tree has a tall and straight tree shape, beautiful tree posture, red leaves in autumn, beautiful flowers, fruits and leaves. It is mainly distributed in Jiangsu, Zhejiang, Anhui, Jiangxi, Fujian, Guangdong, Guangxi, Hunan, Hubei, Sichuan, Guizhou, Yunnan and other places . Sassafras seeds have the characteristics of long dormancy period, irregular germination, and it takes 2 to 3 years to fully germinate and unearth. Seed germination and early seedling growth are sensitive periods to adversity, and the resistance is low. Under natural conditions, the requirements for germination environment are relatively high, the ability of cold resistance is average, and it likes warm and humid climate. In the prior art: germination is from February to ...
