The seed is hard, the skin is not easy to absorb water, direct seeding in the soil, the germination rate is only about 30%, before sowing with 60: 100 ℃ of water for 30 seconds heat treatment; then soaked in warm water for 1 day and night, the germination rate can reach 50%. If treated with concentrated sulfuric acid, when the seed coat blackens, rinse it in clean water immediately, then soak it in warm water, and sow the seed when it expands, the germination rate can reach more than 90%. two。 Planting method ① field direct seeding land preparation conditions are the same as field crops, can be sown in spring

1. Seed treatment Glycyrrhiza uralensis seeds mature from July to August and should be harvested in time. The seed is hard, the skin is not easy to absorb water, direct seeding in the soil, the germination rate is only about 30%, before sowing with 60: 100 ℃ of water for 30 seconds heat treatment; then soaked in warm water for 1 day and night, the germination rate can reach 50%. If treated with concentrated sulfuric acid, when the seed coat blackens, rinse it in clean water immediately, then soak it in warm water, and sow the seed when it expands, the germination rate can reach more than 90%.

two。 Planting method ① field direct seeding land preparation conditions are the same as field crops, which can be sowed in spring or summer. The sowing amount per mu is about 30000g, the sowing depth is 3cm, the row spacing is 50cm, and the seedling protection per mu should reach 7000cm. ② seedling transplanting can be planted by strip sowing or small bed sowing, increase the density, cultivate annual strong seedlings and transplant either in spring or autumn. When planting, ploughing can be used to open ditches, according to row spacing of 60 cm, plant spacing of 15 cm to 20 cm, planting about 7000 plants per mu, planting depth to the rhizome and the ground is appropriate, irrigation after planting. Seedlings generally emerge 5-7 days after sowing, so there should be good soil moisture before sowing and no irrigation after sowing to avoid hardening. ③ planting rhizome will dig fresh licorice rhizome, choose bud eye cut 15cm to 20cm long, use step plough to open ditch, put mother root vertically or obliquely in the ditch, cover soil 10cm, cultivation time can be spring and autumn, irrigation after planting.

3. Field management licorice management is mainly to preserve soil moisture, the first year to ensure the growth of seedlings, 2 years later deep root, some soil moisture can be, generally the use of snow water can ensure normal growth. In the third year of mining, pay attention to preserving the mother root. After digging, level the ground, pour good water and promote the development of new seedlings.
