Soy beans selection
1. Select beans: Spread the soybeans evenly on the seedling tray, carefully select the first step of the beans, and select the ones with worm eyes, black, and particles that are not full.
2. Soak the beans: rinse the soybeans, put them in a clean, oil-free container, add water to the soybeans for about 8-10 cm, and soak for 10 hours.
3. Spread beans: clean the seedling tray, put in a piece of wet seedling paper, and spread the clean soybeans evenly.
4. Rinse: Soak the beans for about 10 hours in the summer and grow up a lot, then rinse them with running water immediately and discard the miscellaneous beans.
Daily management
1. Temperature: Soy beans will affect germination when the temperature exceeds 30 degrees, and will not spoil only at a suitable temperature, and its suitable temperature for germination is about 28 degrees.
2. Watering: Watering is the most important part. Keep it moist at all times, but not too much water. Do not leave water at the bottom of the pan, otherwise it may rot.
3. Light: Soybeans must be protected from light. After spraying water, the seedling tray should be covered with a thick layer of moist gauze.
4. Germination: Soy bean sprouts should be watered thoroughly, and the cotton cloth should also be sprayed and covered, and usually the fine buds will come out the next night.
Precautions
1, when the bean sprouts grow to 15 mm long, water should be thoroughly penetrated without leaving dead ends to prevent red roots and rotten roots.
2. Master the water temperature, water it regularly, and keep it hot and cold in case the buds become reddish brown.
3. The water temperature should not be too high, and the water head should not be too short, otherwise the bean sprouts will have long roots and not long stems.
4. When the bud is 50 mm long, increase the water temperature and increase the heat to prevent the bud root from becoming black.
5. When the bean sprouts are ready, the water temperature of the last three waterings should be reduced, and the sprouts should be removed in time to prevent the sprouts from rotten in the middle.
