Breeding method

Direct seeding is the main method, and seedlings can also be transplanted. Sow in early March to early April, with row spacing of 3-35cm. After applying human and animal manure, evenly sow the seeds into the ditch and cover the soil by 3cm. The height of seedlings is 5cm, and the spacing between plants is about 3cm.

from the first ten days of March to the first ten days of April, select stems and vines with vigorous growth and strong plants without diseases and pests, and cut cuttings with a length of about 25cm, each with about 3 nodes. The row spacing is 3-35cm, the spacing between plants is about 3cm, and the hole depth is about 2cm. Put 2-3 pieces in each hole, and do not insert them backwards. Cover the soil tightly and apply human and animal manure.

When the root tuber is harvested in autumn or before sprouting in spring, the sprouting tillers around the rhizosphere are dug, and the plants with buds and well-growing fibrous roots are selected, and the holes are dug and planted according to the row spacing of 3-35cm and the plant spacing of 25-3cm.
