1、 Curing method

1. Substrate selection: Purple backed vegetable is suitable for growing in moist, fertile and deep soil rich in organic matter. It is recommended to plant it after mixing garden soil, rotten leaf soil, organic fertilizer and sandy soil

2. Temperature management: Purple backed vegetables like to grow in a warm environment. The best growth temperature is 21 ℃ to 29 ℃. It is not resistant to cold, and death may occur when the temperature is lower than 9 ℃ in winter. Summer doesn't like high temperature and strong light. Too high temperature will make its leaves lose water

3. Water management: Purple backed vegetables need a lot of water when growing. After a week of seedling planting, they should be mixed with organic fertilizer and watered once. Usually water once a day. In summer, water according to the dry and wet condition of the soil. The soil is slightly wet

4. Nutrient management: about seven days after the seedlings are planted, they are mixed with human and animal manure and watered once.

Before winter comes, it is necessary to take heat preservation measures for purple back vegetables. It can be covered with soil to increase the thickness of soil layer, or it can be combined with bamboo pole and plastic film to form a greenhouse for thermal insulation

3、 Diagnosis and treatment problems

1. Moths: Purple backed vegetables like to grow in a warm and humid environment, which also provides convenient conditions for the hatching and growth of moths. Methamidophos solution can be mixed with water and sprayed evenly on the surface of purple back vegetables. It can be sprayed several times according to the situation

2. Slow growth: Purple back vegetables have tenacious vitality. Generally, there will be no major problems in their growth. It needs to grow in a warm environment.
