Methods to improve the emergence rate of licorice

Liquoric root is a traditional Chinese medicinal material, which has the functions of tonifying spleen and replenishing qi, clearing away heat and detoxifying. With the strengthening of people's nutrient awareness, its market demand is also increasing. In order to meet the market demand, more and more people begin to plant it. However, when sowing, due to the hard seed skin of licorice, resulting in its low emergence rate, people are very headache, then there is no way to improve the emergence rate of licorice planting, together with Xiaobian to see it.

1, open water soaking method

Put the seeds to be sown into boiling water of 100 degrees C, the amount of boiling water is twice that of the seeds, stir the seeds continuously until the boiling water cools, soak them for 6-8 hours, and take them out after the seeds are fully absorbed. Rub off seed coat by hand, rinse with clean water and sow.

2. Temperature-increasing re-immersion method

Firstly, the seeds are soaked in warm water of 30-40 DEG C for 6-8 hours, so that half or two-thirds of the seeds are saturated with water, and the seeds and the seeds that are not saturated with water are divided into two times, namely, saturated at the bottom and saturated at the top, but do not float on the water surface. At this time, it is necessary to observe once every once in a while, and constantly fish out the soaked plants. Repeat this several times and fish out all the soaked plants. The plants that have not been soaked are soaked in boiling water for 3 minutes, taken out and immediately put into cold water, stimulated alternately by cold and hot, and then soaked in warm water of 60 degrees for 2-4 hours. Finally, all seed coat mucus can be removed and sown. 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 cm, turn the seeds along with the rolling of the grinding plate, pay attention to the change of seed coat, when the seed coat is green and white, soak the seeds in warm water of 40 DEG C for 2-3 hours, wash the mucus and sow. It can also be ground with an electric rice mill. First, the seeds should be graded and the seed coat should be broken by the rice mill, but the cotyledons of the seeds should not be damaged and the integrity of the seeds should be maintained.

4. Sulfuric acid soaking method

The corrosiveness of sulfuric acid can be used to thin the seed coat of licorice. The specific method is as follows: add 1 kg of seeds to 30-35 ml of 98% sulfuric acid, mix them evenly, stir them constantly, and make them contact with sulfuric acid components. After a period of time, when most of the seeds appear black round corrosion spots, quickly wash the seeds with clean water, dry can be. However, during operation, be careful not to contact sulfuric acid with the skin to avoid skin burns.

The above is to improve licorice emergence rate method introduction, hope to help you, want to know more related knowledge, please pay attention to us.
