When harvesting in autumn, choose tubers that are small, disease-free, robust, intact and harmless. After drying, stored in the cellar, the temperature in the cellar is kept at 5: 10 ℃, the tuber is easy to be injured when the temperature is lower than 5 ℃, and the tuber is easy to sprout ahead of time when the temperature is higher than 10 ℃, which is not conducive to tuber propagation. From March to April of the second year, on the finished border, the row spacing was 25 cm, the plant spacing was 15 cm, the depth was 5 cm, the tubers were placed, and the buds were upward. Then cover the soil, and then cover it with a film. A tuber can be divided into several pieces, each of which needs to have a robust bud. Before sowing, tubers are treated with plant ash, which has the effect of sterilization and anti-decay.

2. Seed breeding

From August to September every year, after the seeds are ripe and harvested, wash the berries with water, fish out the seeds, and sow them. Sprinkle seeds on a pre-prepared seedbed, sow about 5 seeds every 100 cm2 and cover with rare earths. In winter, cover the seedbed with rotten and mashed barnyard manure to maintain temperature and humidity, which is conducive to overwintering. In the spring of the second year, when the seedlings were 6-10 cm high, they could be transplanted.

3. Transplanting

In April, when the height of the seedlings was 6 cm ~ 9 cm, the seedlings with strong growth, with a little soil mass, were transplanted into the field according to the row spacing of 20 cm × 15 cm, and the roots were watered once after planting.
