1、 Curing method

1. Temperature: potherb likes to grow in warm places and is not resistant to low temperature. The plant will grow normally only when the maintenance environment temperature is more than 15 degrees. It is not resistant to high temperature. If the maintenance temperature exceeds 30 degrees, the plant will stop growing. Therefore, it is necessary to keep the temperature between 15 degrees and 30 degrees during the maintenance process

2. Watering: it likes a humid living environment. If the soil is dry for a long time, the plant will grow poorly. Its roots are not resistant to waterlogging. It is OK to water the soil completely until the soil is completely wet and there is no ponding in the soil. It needs to be watered once every two days in dry weather and waterlogging prevention in non dry weather

3. Fertilization: its growth needs nutrients. To make the plant grow well, it must be fertilized according to the growth state. If the growth state is good, it can use organic fertilizer once a month. If the growth state is bad, it needs to use compound fertilizer, because the compound fertilizer has sufficient nutrients and comprehensive nutrients, which can meet the needs of all aspects of the plant

4. Light: it is not resistant to strong light. The light is mainly astigmatism. The lighting time every day is guaranteed to be four hours

2、 Breeding skills

1. Propagation: it can use the sowing method to propagate. First, select the seeds, remove the withered and moldy seeds, and leave the seeds with full particles. Then sprinkle the seeds evenly into the prepared cultivation base, cover it with a layer of soil, spray water mist on the cultivation base basin with a watering can, and spray the soil on the plant surface

2. Weeding: the plant of Rehmannia is relatively small, which is easy to mix with weeds, and it is difficult to weed. In order to avoid unnecessary nutrient consumption, it is necessary to pull weeds frequently in the process of management. You can't wait until the grass is large and press the seedlings before pulling. For weeds, find them early and deal with them early

3、 Problem diagnosis

1. Insect pests: its main pests are aphids. After infected with aphids, the leaves will turn green and black and can't be eaten. Moreover, the diseased plants will also infect bacteria. If aphids are found, it is necessary to use 40% dimethoate 1500 solution to spray the diseased plants for treatment

2. Disease: its main disease is downy mildew virus, which usually occurs in summer and autumn. At this time, the air is relatively humid, which is easy to breed bacteria. Chlorothalonil can be used for spraying in the early stage of the disease

4、 Other issues

1. Edible: edible

2. Whether indoor seeds can be planted: it can be planted indoors, because the plant is small and the requirements for environmental protection are not high, so family breeding is OK
