Detailed Explanation of Key Techniques for Soilless Cultivation of Radish Sprouts

Sprouts are an emerging vegetable cultivation method in recent years. The bean sprouts people commonly eat are actually a type of sprout, only now there are more categories of sprouts. Radish is a vegetable that everyone likes, but in the past mainly the root part of the radish was eaten, and the leaves did not taste very good, but when cultivated as sprouts the taste is very good, and they are loved by everyone. Soilless cultivation has fewer diseases and is safer.

1. Preparation Work

Prepare the container to be used for cultivation. Generally, a dedicated seedling tray is prepared and disinfected with 0.4% formaldehyde solution. If the quantity is large, you can directly use bleaching powder mixed with some water and soak directly for a period of time. After cleaning and drying, it can be used. It is best to choose a seedling tray in the lengthwise direction, as it is easier to manage. Choose seeds that germinate easily and germinate uniformly, choose pure varieties, and choose plump, large seeds.

2. Treating the Seeds

Select the seeds with water, remove the floating seeds and defective seeds, then use 50°C hot water and stir to soak for more than ten minutes. The water temperature will gradually drop. When the water temperature reaches over 20°C, stop stirring. Change to clean water and soak for several hours. After they have absorbed enough water, clean them. After draining, put them in a container to germinate. The germination temperature is 25°C. Maintain the temperature, and the bottom of the container must be able to drain water.

3. Sowing and Cultivation

Take a clean seedling tray, lay down newspaper and then lay down paper with good water absorption, spray water, and let all the paper be thoroughly soaked. Evenly scatter some seeds that have already sprouted white after germination onto the seedling tray. After sowing, you can lay down a sheet of paper that the seeds can penetrate, then cover with an empty basin to ensure no light is seen, then place them on the shelf in order.

4. Management After Seedling Emergence

Before sprouting, receive weak light and water once a day. After the seedlings emerge and grow to 4 cm high, use nutrient solution together with water, watering 3 times a day, adding a little nutrient solution each time. When the cotyledons are about to unfold, sufficient sunlight is needed, so increase the light, but they still cannot receive strong light, as strong light will cause damage from water loss. As light increases, the frequency of watering increases accordingly, to 4 times a day. The cotyledons will soon unfold, and then they can be harvested.

Soilless cultivation of radish sprouts basically has no diseases, and then the growth speed is much faster. It is relatively clean and healthy. It is welcomed by everyone in the market. The above is a simple cultivation and operation method.
