Yellow soybean selection

1. Selecting beans: Spread the yellow soybeans evenly over the seedling tray, carefully select the beans as the first step, pick out and discard those with insect holes, black spots, or plumpness that is not full.

2. Soaking beans: Rinse the yellow soybeans once, put them in a clean oil-free container, add water up to about 8-10 cm above the yellow soybeans, and soak for 10 hours.

3. Spreading beans: Clean the seedling tray, put in a piece of seedling paper soaked in water, then evenly spread the clean yellow soybeans over it.

4. Rinsing: In summer, generally after soaking for about 10 hours the beans have already grown a lot, at this time immediately rinse them clean with running water, and discard the mixed beans.

Daily management

1. Temperature: Yellow soybeans will have their sprouting affected when the temperature exceeds 30 degrees, and only at a suitable temperature will they not rot; the suitable temperature for sprouting is around 28 degrees.

2. Watering: Watering is the most important step, keep them moist at all times, but the water must not be too much, and water must not remain at the bottom of the tray, otherwise the roots may rot.

3. Light: Yellow soybeans must be sprouted away from light; after spraying water, cover the seedling tray with a thick layer of moist gauze.

4. Sprouting: When watering yellow soybean sprouts, water thoroughly, and continue to spray the cotton cloth moist and cover it on top; generally by the evening of the second day fine tender sprouts will have emerged.

Precautions

1. When the sprouts grow to 15 mm long, water thoroughly without leaving any, to prevent red roots and rotten roots.

2. Master the water temperature well, water at fixed times, and do not let the water go from cold to hot suddenly, to prevent the sprout roots from turning reddish-brown.

3. The watering temperature should not be too high, and the watering duration should not be too short, otherwise the sprouts will only grow roots and not stems.

4. When the sprouts are 50 mm long, the water temperature should be raised and heat increased to prevent the sprout roots from turning black.

5. When the sprouts are almost ready, lower the water temperature for the last three waterings, and take them out promptly when sprouting is complete, to prevent the sprouts from rotting in the middle.
