1. Temperature: it can withstand low temperature. As long as the temperature is above 5 degrees, it can grow normally. When the temperature is 20 degrees, the growth condition is the best. The highest temperature should not exceed 35 degrees. If it exceeds 35 degrees, it will grow slowly.
2. Watering: water control is required after seedling emergence to promote root growth. If the weather is relatively dry, the land is lack of water, so it needs to be watered manually. If the temperature exceeds 30 ℃, it needs to be watered every other day. The precipitation in rainy season is relatively large. It needs to be well drained to avoid the root being waterlogged.
3. Fertilization: in addition to the base fertilizer mixed in the soil during planting, topdressing is needed during the growing period. Topdressing Time is generally in the summer festival. The fertilizer can be used in bean cake, compound fertilizer and other fertilizer types. When applying fertilizer, the fertilizer should not directly contact the root of the plant to avoid fertilizer damage.
4. Light: it is not resistant to strong light, so the light should be mainly astigmatism, and the daily light time should be four or five hours.

After harvesting the plant, take down the tuber roots for medicine, then select the roots that are disease-free and strong, cut them into small pieces with the sterilized blade, each small piece must have buds on it, put them in a cool place for half a day, start planting according to the row spacing of 25 cm, bury them with soil after sowing, and finally hand in enough water, about two weeks will be the seedling.
2. Bud removal: for plants that do not need to be planted, bud removal should be carried out, because the main part of the harvest is the rhizome rather than the fruit, so in order to avoid unnecessary nutrient consumption, it is necessary to gather nutrients by bud removal.
1. Insect damage: in summer, aphids are easy to infect. Aphids mainly feed on the young leaves of plants and spread diseases, which will affect the growth of plants. Therefore, treatment must be started when aphids are found. During the treatment, you can use chemical insecticides and other insecticides, or you can use 1:1:10 tobacco lime water for insect control.
2. Pathological changes: plants are more susceptible to root rot. root rot, as the name implies, is the root rot. It needs to be irrigated with the bacteriophage.
1. Edible: it can't be eaten directly, but it can be used as medicine.
2. Toxic: there are some side effects if there are too many Chinese herbal medicines. Therefore, please follow the doctor's instructions and pay attention to the dosage.
