How to deal with licorice seeds?
At present, there are the following methods used in production: (1) sand grinding method: the licorice seeds and clean river sand are mixed at a ratio of 1 to 1, put into a container, stirred repeatedly to make them rub, and can be sown when the seed coat is not bright. This method is labor-consuming and is only suitable for the treatment of a small number of seeds. (2) Rice milling machine treatment: licorice seeds were milled with electric rice grinder for 3 times in order to cut the seed coat and keep the seed unbroken. (3) heating and re-soaking method: the seeds were soaked in 60 ℃ warm water for 6-8 hours, and the seeds that had been soaked in the upper layer were bleached out by "rice washing method". Then soak the seeds in 100 ℃ boiling water for 2-3 seconds, immediately put them into cold water to stimulate the seeds, then soak them in 60 ℃ warm water for 2-4 hours, and finally mix all the treated seeds together and wash off the mucus with clean water to sow seeds.

Adult eggs green fruit seed coat, larvae after hatching that eat seeds, and pupate in the seeds, adult emergence, bite seed coat escape, killed seeds eat into empty shell, seed coat and pod left on the round small emergence hole, this insect has a great impact on yield. Control methods: ① Remove residual leaves in winter to reduce insect sources. (2) The seeds must be treated before planting, eliminating insects or dressing seeds with carbaryl powder. (3) Spraying pesticides in the development stage, especially in the green fruit stage.

Skillful treatment of licorice seeds
The treatment of the seeds of traditional Chinese medicine before sowing can prevent and control diseases and insect pests, improve the germination rate, and play an important role in Miaoqi, Miaoquan, and Miaozhuang. it is the primary prerequisite for stable and high yield, and generally the yield can be increased by 5% and 20%. In this paper, the treatment methods of licorice seeds are introduced as follows: licorice seeds are thick and hard, and the seeds are not easy to germinate and can destroy the epidermis. There are three methods: ① uses the high-speed rolling of the rice mill to make the seeds rub and collide with each other and injure the epidermis (suitable for a large number of seeds); ② grinds seeds and coarse sand together for 5 minutes (suitable for a small number of seeds)
