The latest method to improve the emergence rate of licorice

Licorice is a traditional Chinese medicine, which can tonify the spleen and replenish qi, clear heat and detoxify. With the strengthening of people's awareness of nutrients, its market demand is also increasing. In order to meet the market demand, more and more people begin to plant. But when sowing, because the seed bark of licorice is hard, which leads to its low emergence rate and makes people have a headache, then is there any way to improve the emergence rate of licorice planting? let's take a look at it with the editor.

1. Seed soaking in boiling water

Put the seeds to be sown in 100 degrees boiling water, the amount of boiling water is 2 times that of the seeds, stir the seeds constantly until the water is cooled, soak for 6-8 hours, and then the seeds can be fully absorbed. Rub off the seed coat with your hands, rinse it with clean water and sow.

2. Heating and re-soaking method

First of all, soak the seeds in warm water of 30-40 degrees for 6-8 hours, so that half or 2/3 of the seeds are saturated, and the unsaturated seeds are divided into two times, saturated at the bottom, saturated at the top, but not floating on the surface. At this time, it is necessary to observe every other time, constantly fishing out the soaked planting, so repeatedly, all the soaked planting can be removed. For the unsoaked planting, soak it in boiling water for 3 minutes, fish it out and immediately put it into cold water, after alternating cold and hot stimulation, and then soak it in 60 degrees warm water for 2-4 hours. Finally, all the seed coat mucus is removed and the seed can be sown, and the emergence rate of this method can reach 90%.

3. Rice milling method

Spread the seeds on the grinding plate, the thickness is about 3 centimeters, turn the seeds with the rolling of the grinding plate, and with the change of the seed coat, when the seed coat is green and white, soak the seeds in 40 degrees warm water for 2-3 hours, wash the mucus and sow the seeds. The electric rice grinder can also be used for grinding. first of all, the seeds should be graded and the seed coat should be cut by the rice grinder, but the cotyledons of the seeds will not be damaged and the integrity of the seeds can be maintained.

4. Sulfuric acid soaking method

The corrosiveness of sulfuric acid can be used to thin the seed coat of licorice by adding 1 kg of seed to 98% sulfuric acid 30-35 ml, mixing it evenly and stirring constantly to make it come into contact with sulfuric acid. After a period of time, when black round corrosion spots appear on most seeds, rinse the seeds quickly with clean water and dry them. But in the operation should be careful, do not contact the sulfuric acid to the skin, so as not to cause skin burns.

The above is the introduction of the methods to improve the emergence rate of licorice. I hope it can help you. If you want to know more about it, please follow us.
