1. Sowing: generally, the seeds are sown from March to April in spring. The seeds need to be picked after they mature in November. Then rub off the outer skin and rinse with water. Then it is wrapped in the wet sand for germination. In the second year, when the seeds are exposed to the white, they can be sown in the soil, and humus soil and plant ash can be used. Wait until April to May of next year to transplant
2. Rhizome: when digging out the rhizome in winter, it is necessary to select the one that looks undamaged and free of diseases and insect pests. If there is a terminal bud on the top, cut it from a place 3-4cm long. After the wound is stained with grass ash, plant it, and the next spring, the seedlings will grow. If it doesn't have terminal buds, it can be cut into two sections and soaked in a 300 times solution of 50% carbendazim for 30 minutes. It can be transplanted into the field after being cultivated in April next year.
After transplanting, weeding should be carried out in time to avoid competing for nutrients. Start to apply heavy fertilizer from June to ensure it can grow well. We also need to pay attention to the prevention and control of diseases and insect pests.
