1. Select beans:
Choose beans first. There are many kinds of soybeans on the market. Choosing this small soybean with high germination rate is also the new soybean of that year. Otherwise, the number of buds will be greatly reduced.
Spread the soybeans evenly on the seedling tray and carefully select the beans. The first step is to choose the ones with wormholes, the black ones and the ones with incomplete particles.
2. Soak beans:
Put the beans in a clean oil-free container, add water to about 8 ~ 10 cm above the beans, soak for one night for about 8 hours, and you will see the beans swell.
3. Spread beans:
Find a drink bottle, wash it, cut it, and make a hole in the bottom.
Pour the soaked beans in, warm water from the top and out from the bottom. (Water will soak all the beans)
Wrap it in opaque cloth and bottles and water it twice a day on average.
4. Rinse:
Generally, beans soaked in 10 hour in summer have grown up a lot. At this point, immediately rinse with running water and discard.
Four days later, the bean sprouts came out. I gave birth to bean sprouts at room temperature. If the temperature is high, bean sprouts will grow faster.
Second, the daily management:
1. Temperature: When the temperature of soybean exceeds 30 degrees, it will affect germination, and it will not rot only at a suitable temperature. The suitable temperature for germination is about 28℃.
2. Watering: Watering is the most important link. Keep it moist at all times, but don't have too much water, and don't leave water at the bottom of the dish, otherwise the roots may rot.
3. Light: soybeans must be protected from light to grow seedlings. After spraying water, cover the seedling tray with a thick layer of wet gauze.
4. Germination: The bean sprouts should be drenched with water, and the cotton cloth should continue to be wetted, and then covered on it. Usually the buds will come out the next night.
Three. Precautions:
1. When the bean sprouts grow to 15mm long, water them, leaving no dead ends to prevent red roots from rotting.
2. Master the water temperature, water regularly, and use water that is not hot or cold to prevent buds and roots from turning reddish brown.
3. The watering temperature should not be too high and the water head should not be too short, otherwise the bean sprouts will only grow roots and not stalks.
4. When the bud grows to 50 mm, it is necessary to increase the water temperature and heat to prevent the bud root from blackening.
5. After the bean sprouts are finished, the water temperature of the last three watering should be lowered, and the bean sprouts should be taken out in time after germination to prevent the bean sprouts from rotting halfway.
