Correct methods for thinning and final thinning of licorice seedlings
Licorice is mostly cultivated in arid regions. To ensure a high emergence rate, when direct seeding is used, the seeding rate is often on the high side; therefore, after emergence, seedlings must be thinned and finally thinned according to their condition. Seedlings generally emerge about 10 days after sowing. When the seedlings have grown 2-3 true leaves, thin them, pulling out the overly dense and weak seedlings so that the spacing between seedlings remains at about 5 cm, which favors seedling growth and development and the formation of robust plants. When the seedlings have grown 3-5 true leaves or the seedlings are more than 6 cm tall, carry out final thinning, with a plant spacing of 10-15 cm being suitable, leaving 20,000-25,000
