Detailed Explanation of Black Bean Sprout Cultivation Methods and Key Technical Points
Select some healthy, plump black bean seeds, soak them in 60°C warm water for 3 minutes, then remove and rinse with cold water, place them in 20°C warm water to soak for 10 hours, and finally remove them to let them sprout. After they sprout, evenly spread them on a seedling tray, cover with a thin layer of paper, and place them in a shaded spot at 28°C. After a week, green sprouts will grow. After half a month, they can be harvested. During this period, water once in the morning and once in the evening each day.
How are black bean sprouts managed during the seedling stage?
1. Black bean sprouts usually reach 3-4 cm in about 30 hours. Place the foam box on a stand or on the ground, take one vial of rootless bean sprout agent (2 ml) and mix with 1-2 kg of water, and spray the sprouts to reduce the formation of lateral roots and root hairs and increase the cotyledon area.
2. When black bean sprouts are 8-9 cm tall, take one vial of thickening agent (2 ml) and mix with 1-1.5 kg of water, and spray the sprouts to inhibit true leaf elongation, make the stems thicker and more crisp and tender, reduce fiber content, and make the bean cotyledons plump, fresh green and glossy, improving their market quality.
3. Throughout the entire production process of black bean sprouts, spray water 2-4 times a day. If the temperature is high and humidity is low, spray more; otherwise, spray less. Spray less in the early growth stage; in the later stage growth is rapid and water demand is high, so spray more.
4. During the production of black bean sprouts, moldy and rotten seeds should be removed promptly to avoid creating a center of infection and contaminating surrounding bean seeds. When the foam box is reused, it must be thoroughly disinfected with fungicide and exposed to direct sunlight for 3-4 hours.
