1、 Curing method

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 maximum temperature should not exceed 35 degrees. If it exceeds 35 degrees, it will grow slowly

2. Watering: water control is required after emergence, in order to promote root growth. If the weather is relatively dry, the land is lack of water and needs to be watered manually. If the temperature exceeds 30 degrees, it needs to be watered every other day. The precipitation in rainy season is relatively large, so it needs to be drained to avoid waterlogging at the root

3. Fertilization: in addition to the base fertilizer mixed in the soil during planting, topdressing is also required during the growth period. The topdressing time is generally in the summer festival. Fertilizer seeds such as bean cake and compound fertilizer can be used. During fertilization, 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. The daily light time should be guaranteed to be four or five hours

2、 Breeding skills

1. Propagation: it can be propagated by dividing plants. The time is after the cold dew Festival. After harvesting the plants, take down the root tubers used as medicine, and then select the disease-free and strong rhizomes, cut them into small pieces with sterilized blades. There must be buds on each small piece, put them in a cool place for half a day, start hole planting according to the row spacing of 25 cm, bury them with soil after sowing, and finally hand in enough water. Seedlings can emerge in about two weeks

2. Bud removal: for plants that do not need to be planted, buds should be removed, because the main part of harvest is rhizome rather than fruit. Therefore, in order to avoid unnecessary nutrient consumption, buds need to be removed to concentrate nutrients

3、 Problem diagnosis

1. Insect pests: in summer, it is easy to be infected with aphids. Aphids mainly feed on the tender leaves of plants and spread diseases, which will affect the growth of plants. Therefore, treatment must be started when aphids are found. During treatment, chemical agents and other insecticides can be used for insect control, and 1:1:10 tobacco lime water can also be used for insect control treatment

2. Pathological changes: plants are more susceptible to root rot. root rot, as the name suggests, is the root rot. It needs to be watered with Tuvalu

4、 Other issues

1. Edible: it can't be eaten directly, but it can be used as medicine

2. Toxic: if Chinese herbal medicine is overdosed, there are some side effects. Therefore, please follow the doctor's instructions and pay attention to the dosage
