Soil: Purple cabbage needs to grow in acidic soil with strong air permeability and sufficient fertility. Temperature: It is afraid of cold and does not like high temperatures. The optimal growth temperature is between 21℃ and 29℃. Moisture: Because it likes to be slightly moist, you can water it every day to keep the soil moist. Nutrients: Organic fertilizer can be applied once during the seedling stage, and fertilizer needs to be applied after harvesting.

1. Maintenance method

1. Substrate selection: Purpurea is suitable for growing in moist, fertile, deep soil rich in organic matter. It is recommended to use garden soil, leaf mold soil, organic fertilizer, and sandy soil. Plant after mixed configuration.

2. Temperature management: Purpurea likes to grow in warm weather In the environment, the optimal growth temperature is 21℃ to 29℃. It is intolerant to cold and may die if the temperature falls below 9°C in winter. It doesn't like high temperatures and strong light in summer. Too high temperatures will cause its leaves to lose moisture.

3. Water management: Purple cabbage requires a lot of water when growing. Mix organic fertilizer and water it once a week after the seedlings are planted. Normally, watering can be done once a day. In summer, watering should be based on the dryness and wetness of the soil. The soil should be slightly moist.

4. Nutrient management: Mix humans and animals about seven days after seedlings are planted. The manure is poured with fertilizer and water once, and then mixed with organic fertilizer and urea and watered once every time after picking. At the same time, you can also sprinkle an appropriate amount of plant ash evenly around the purple cabbage to provide it with nutrients.

2. Breeding skills

1. Cutting: Summer and autumn are the best seasons for cutting. Before cutting, first rake the soil to keep it in a loose state. Then cut cuttings about 9 cm from the plant. Cut off the large leaves and insert them into the soil about 6 cm.

2. Overwintering: Purple cabbage is not cold-tolerant, and its growth slows down when the temperature is below 9°C. Insulation measures need to be taken for purple cabbage before winter comes. You can cover it with soil to increase the thickness of the soil layer, or use bamboo poles and plastic film to form a greenhouse insulation.

3. Problem diagnosis and treatment

1 , Moths: Purpurea prefers to grow in a warm and moist environment, which also provides convenient conditions for the hatching and growth of moths. You can use methamidophos solution mixed with water and spray it evenly on the surface of purple back vegetables. You can spray it several times depending on the situation to solve the problem.

2. Slow growth: Purple cabbage has strong vitality and generally does not cause major growth problems. It needs to grow in a warm environment. Slow growth may be caused by the surrounding environment being too cold, which can be alleviated by increasing the temperature in a greenhouse or covering it with soil.

IV. Other questions

1 , whether it can be raised in the open: it can be raised in the open. Purple cabbage can be planted in moist soil. Pay attention to heat preservation in winter, especially in northern winter, and heat preservation measures must be taken.

2. Whether it can be exposed to rain: It can be exposed to rain. Purpurea prefers a humid growth environment and requires a lot of water to grow. Proper rain can promote its growth.
