1、 How to plant

1. Sowing: sowing is generally carried out from March to April in spring. After the seeds mature in November, they need to be picked. Then rub off the outer skin and rinse it with clean water. Then wrap it in wet sand for germination. In the second year, after the seeds are exposed, they are sown in the soil. Humus soil and plant ash can be used. Transplanting can be carried out from April to May of the next year

2. Rhizome: when digging out rhizomes in winter, you need to choose ones that look harmless and free from diseases and pests. If there is a terminal bud on it, cut it from the place with a length of 3-4cm, plant it after the wound is stained with plant ash, and the seedlings will grow in the next spring. If there is no terminal bud, it can be cut into pieces every two sections and soaked in 50% carbendazim mixed with 300 times of solution for 30 minutes. After the seedlings are cultivated in April next year, they can be transplanted into the field

2、 What should we pay attention to

After transplanting, it is necessary to weed in time to avoid competing for nutrients. Heavy fertilizer will be applied from June to ensure that it can grow well. We also need to pay attention to the prevention and control of diseases and pests
