Red beans can produce bean sprouts. Red bean sprouts are of good quality, highly nutritious, and have unique medicinal value.

The method is as follows:

1. For production sites and cultivation container sites, you can choose modified greenhouses, greenhouses, etc., and cover them with sunshade nets or straw curtains on top, and add additional Spraying and ventilation equipment. The temperature in the venue must also be kept above 16°C. Cultivation racks can also be used for three-dimensional cultivation. The cultivation racks are assembled with angle irons. They can also be built with bamboo or wood, with 4 to 5 layers and a layer spacing of 30 cm. The cultivation container should be one with a flat bottom, moderate size, light weight, easy to move, and strong and durable. Watering generally uses micro-sprinkler devices, sprayers, shower heads, etc.

2. Seed selection: Select new seeds with full grains, bright color, white navel, and a germination rate of more than 95%. Remove shriveled, broken, insect-eaten beans and impurities, wash them with clean water, and rinse them. Remove the shriveled kernels and clean the seeds.

3. Disinfect cultivation equipment with 0.2% to 0.5% potassium permanganate solution or 0.2% bleaching powder, soak and scrub, then rinse with clean water and expose to the sun. The production site is fumigated and disinfected with formaldehyde, and ultraviolet lamps are added for disinfection. Reused substrates are rinsed with clean water and then sterilized in a pressure steamer.

4. Seed soaking and germination. Put the cleaned seeds into gauze and soak them in clean water for 16 to 24 hours. During this period, change the water and wash 4 times. After soaking the seeds, soak them in warm water at 55°C for 10 minutes, or disinfect them with potassium permanganate solution to kill the germs on the surface of the seeds and in the potential seeds. Then wash the seeds twice, wrap them in a sack or towel, and wrap them in a sack or towel. It is placed at 20°C to 25°C for germination and washed twice a day with warm water. After two days, the seeds will turn white and can be cultivated.

5. Cultivation: Clean the seedling tray and cover it with soaked cotton cloth, non-woven fabric or foam sheet. Sow the sprouted red beans evenly on top, about 300 grams per plate, and do not stack them. Cover it with another layer of cotton cloth. Finally, water it and place it on the cultivation stand. The temperature is controlled at 20℃～25℃. Spray water 3 to 4 times a day and keep the air humidity at 80% to 90%. Change the seedling tray once a day.

6. Harvesting: When the red bean sprouts are 15 cm tall, the first pair of true leaves have not yet fully expanded, the tissue is tender and not fibrotic, cut them off along the base of the stem.
