Cultivation methods and precautions of green radish

1. Cultivation methods of radish: soil preparation, light and temperature requirements, watering methods and fertilizer application.

1. Soil preparation

The soil for cultivating radish can be mixed with humus soil, garden soil, river sand and red loam soil. Adjust the soil to be slightly acidic, and ensure that the soil is loose, breathable and rich in humus nutrition.

2. Light and temperature requirements

The temperature environment of 15 ~ 25℃ is most suitable for the growth and development of radish. Green radish is afraid of strong light, so it is more suitable to breed in semi-cloudy environment. Warm and bright scattered light can make the leaves green.

3. Watering method

Green radish likes to be wet and is afraid of waterlogging. Keep the soil moist in spring, summer and autumn, and water it once every 4-5 days in spring and autumn and once every 1-2 days in summer. The temperature is too low in winter, so it is more appropriate to water it once every 1~2 weeks, and the water temperature should be the same as the room temperature.

4, fertilizer application

During the growth period, the radish must be given enough fertilizer nutrition. Apply diluted fertilizer solution to the radish every half month, and the fertilizer type can be selected from compound fertilizer of nitrogen, phosphorus and potassium, decomposed cake fertilizer or potassium dihydrogen phosphate solution. Applying thick fertilizer to produce fertilizer is easy to cause fertilizer damage and root rot.

Second, the precautions for the cultivation of green radish:

When cultivating green radish, it is necessary to trim the branches and leaves to avoid unnecessary nutrient loss and ensure the ornamental of the plants. Good ventilation conditions can effectively avoid pests and diseases, and prepare for cold and warmth before winter.
