1、 Curing method

1. Substrate: fertile and soft soil should be used for cultivating plantain. If it has good drainage, it is the best. Generally, it can be planted in rice fields, vegetable fields and other places

2. Temperature: it is a plant that cannot withstand high temperature. It grows well at about 20 ℃. In summer, the temperature should not be higher than 30 ℃. If it is too high, it should be cooled and replenished. It is better to keep the temperature above 15 ℃ in winter

3. Replenish water: plantain prefers to moisten some soil. Therefore, it is necessary to replenish water in time during maintenance, so that there is a certain amount of water in the soil. However, if the temperature is low, it needs less water

4. Light: it does not require high light during growth. However, it is a relatively light loving plant. If it is raised in a good light environment, its growth speed will be faster. If the light is poor, the leaves will be very thin

2、 Breeding skills

1. Reproduction: sowing is usually used, and fertile soil should be selected before sowing. Then choose healthy seeds, mix them with fine sand and rub them back and forth gently to remove some oil. After sowing, cover the soil and water, and then wait for the seeds to germinate

2. Weeding: in the process of its growth, it is necessary to do a good job of weeding and remove some weeds around the plant in time. Generally, weeding can be carried out together with fertilization

3、 Diagnosis and treatment problems

1. Disease: the common disease is powdery mildew. White powder will appear on the leaves after the disease. After it is found to be sick, it can be sprayed with methyltobuzin. If there is no timely prevention and control, plantain is likely to die

2. Insect pests: aphids are the main ones that will damage plantain. When insects are found, they need to buy insecticides immediately and spray them for treatment

4、 Other issues

1. Edible: it is edible when it is in the seedling state. If it is to be picked, it should be carried out in spring, probably from April to May

2. Toxic or not: it is not toxic, but has certain medicinal value
