Detailed Explanation of the Latest Soilless Cultivation Technology for Radish Sprouts

Sprouts are an emerging vegetable cultivation method of recent years. The bean sprouts people commonly eat are actually a type of sprout as well, it is just that the categories of sprouts have now increased. Radish is a vegetable that everyone likes, but in the past mainly the root and stem part of the radish was eaten, and the leaves were not very good in taste, 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 special seedling tray is prepared and disinfected with a 0.4% formaldehyde solution. If the quantity is very large, you can directly use bleaching powder mixed with some water and soak them directly for a period of time. After washing clean and drying, they can be used. It is best to choose seedling trays oriented in the direction of vegetable growth, as they are 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 damaged seeds, then soak them in 50-degree hot water with stirring for more than ten minutes. The water temperature will gradually drop, and when the water temperature reaches more than 20 degrees, you can stop stirring. Change to clean water and soak for several hours. After they have absorbed enough water, wash them clean. After draining, put them in a container to promote germination. The germination temperature is 25 degrees. 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 sprinkle some of the seeds that have already sprouted white after germination promotion onto the seedling tray. After sowing, you can lay down a piece of paper that the seeds can penetrate, then cover with an empty basin to ensure no light is seen, and then place them in order on the rack.

4. Seedling emergence management

Before budding, 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 must not receive strong light, as strong light will cause damage from water loss. As light increases, the number of waterings should increase accordingly, 4 times a day. The cotyledons will unfold quickly, and then they can be harvested.

Radish sprouts under soilless cultivation basically have no diseases, and then their growth speed is much faster. They are relatively clean and healthy. They are welcomed by everyone in the market. The above is a simple cultivation and operation method.
