First, the selected soybeans with high quality and high germination rate are soaked for about 10 hour, then the soybeans are put in a microwave oven for 1 day, put in a wooden bucket with a drainage rack, covered with a layer of wet linen, and watered frequently to keep them moist.

Soybean sprouts are a kind of vegetables often eaten in life, which are not only rich in taste, but also beneficial to human health. However, many people don't know what the trick is to make soybean sprouts at home. The first thing is to choose high-quality soybeans with high germination rate. The soybeans selected should be carefully observed, and dry or wormy ones should not be used, mainly soybeans with Huang Liang color and bluish white watercress.

Rinse the selected soybeans with clear water once, then put them in a clean container without impurities, and then add a proper amount of water to keep the soybeans submerged on the water surface. Put them in a ventilated and warm environment and soak them for about 10 hour. When the water evaporates slowly, add water slowly, and the soaking time can be prolonged in low weather and temperature.

In order to germinate soybean sprouts better, it is best to carry out proper high temperature treatment. First, put the soaked soybeans in the microwave oven at home, keep the temperature at about 28 degrees, about 1 day, take them out and clean them once, and throw away the rotten or blackened soybeans to avoid affecting the germination of other soybeans.

Prepare a small wooden barrel, make a drainage rack in the middle, cover the rack with a layer of germinating paper, put the washed soybeans in it, and stir them evenly by hand to keep the soybeans loose and flat, cover them with a layer of wet linen, and water them once.

Watering is the key to soybean germination, and it is also an essential step. Watering should be carried out in the form of spraying or atomizing, and soybeans should always be kept moist, and they should not be allowed to dry. When watering, linen should be uncovered, and the water dripping from soybeans should not be used twice to avoid affecting the normal germination of soybeans.

Then put the soybeans in a dark and warm room, and keep a good ventilation environment. If it is hot in summer, you can increase the number of water sprays. Generally, you should spray water every three hours to keep them moist, and water them thoroughly every time. The water temperature should not be too high, and buds can grow after about one week.
