Planting techniques of black bean sprouts

Select some high-quality black bean seeds, rinse them in 30-degree water for 2-3 times, then soak the seeds overnight, remove, wash and spread them evenly on the seedling tray, then cover with paper and put them in a cool place. During this period, you should be drenched with water every morning and evening. If it is hot in summer, you can increase the number of times of watering. After a week, the sprouts will grow, and you can pick and eat them in about 10 days. If you want to eat tender shoots, you can pick them when they grow to 5cm or so.

The detailed steps of planting black bean sprouts and vegetables:

1. Variety selection

The varieties of black bean seedlings should choose the varieties with fast sprouting, short growth cycle, uniform seedling thickness, strong disease resistance and good palatability. at present, the commonly used varieties are cattle-driving black bean and top black, and it is best to use the black bean harvested in the same year.

2. Seed treatment

Before planting black bean seedlings, the seeds are first selected by air and bleached with water, and the seeds damaged by mechanical rolling and moth-eaten, moldy and too small are removed. When floating in water, they should be scrubbed repeatedly with their hands, and the impurities and inferior beans should be picked up repeatedly, and then the black beans are fished into a bamboo sieve to control the moisture.

3. Soaking seeds in warm soup

Pour the controlled black beans into 55 ℃ warm water and soak the seeds in warm soup. Keep stirring quickly in one direction. The amount of water used to soak the seeds is twice the amount of dry seeds. Add appropriate amount of cold water when stirring for about 15 minutes and soak when the temperature is reduced to 25 ℃. At the same time, add one (2 ml) rootless bean sprouting, stir evenly, soak the seeds for 24 hours, at this time the black beans have absorbed enough water, rinse with clean water for 2 times, pour into the bamboo sieve to control the moisture, let it stand for 3 minutes, ready to sprout.

4. Disinfection and budding

Spread a layer of toilet paper on the bottom of the sterilized foam box, spray it with 25: 30 ℃ warm water, spread black beans evenly in the box, let beans close to beans in the bottom of the box, each box with dried beans 350g, spread with 20 ℃ warm water spray, spray water with no dripping water in the foam box, do not store water, so as to avoid seed rot. Then a stack of 6 plates is carried out to promote sprouting.

5. Seedling stage management

In the whole production process of black bean seedlings, water is sprayed 2 times 4 times a day, if the temperature is high and humidity is small, otherwise there is less spraying, less spraying in the early growth stage, rapid growth in the later stage and large water demand, so more spraying should be done. In addition, moldy seeds should be removed in time so as not to cause the disease center and infect the surrounding bean seeds. When the foam box is reused, it should be thoroughly sterilized with rotten fungus and exposed to the sun for 3-4 hours.

The above is the introduction of the planting technology of black bean sprouts. I hope it will be helpful to you.
