Last Updated: 2024/11/05, Licorice seeds begin to germinate at 10-15 degrees, and 15-20 degrees germinate most quickly, and the germination rate of aged seeds decreases. One of the biggest characteristics of licorice is the hard seed phenomenon, which is usually between 70 and 90 percent, and it is difficult to emerge after sowing, so when seeds are propagated in production, they must be treated before sowing. The general treatment methods are as follows: ⑴ soaking seeds in boiling water, ⑵ concentrated sulfuric acid soaking seeds, ⑶ broken glass grinding. ⑷ rice mill, among which the rice mill has the best grinding effect. Generally, the rice mill is used 1-2 times before sowing.

Licorice seeds begin to germinate at 10-15 degrees, and germinate fastest at 15-20 degrees, and the germination rate of aged seeds decreases. One of the greatest characteristics of licorice is that it has a hard seed phenomenon, which is usually between 70 and 90 percent, and it is difficult to emerge after sowing. Therefore, when seeds are used for reproduction in production, treatment must be carried out before sowing. The general treatment methods are as follows:

⑴ soaked seeds in boiling water, ⑵ concentrated sulfuric acid soaked seeds, ⑶ broken glass grinding ⑷ rice milling machine grinding, in which rice milling machine grinding effect is the best, generally in a few days before sowing with rice milling machine grinding 1-2 times, see the seed can be scraped, must not break the seed coat, note that seed treatment must be carried out a few days before sowing, early treatment affects the germination rate, such as bought seeds have been treated, and do not know how long to deal with or surface mosquito phenomenon of the seeds had better not be used, because the germination rate is low.
