1. Seed soaking: firstly, the ultra-small particles, damage, mildew and impurities of the seeds are removed, and then the cleaned seeds are put into plastic pots or plastic buckets, soaked in nutrient solution for 6- 100 times, and the dilution is 2-3 times of the seed amount; When the seeds have absorbed enough water, take them out, rinse them with clean water, accelerate germination at 20-25℃, and sow them when they are exposed, or directly sow the seeds in a plastic tray and accelerate germination after soaking;

2. Sowing: Before sowing, clean the plastic tray, spread absorbent paper (rice paper is enough) on the bottom of the seedling tray as the cultivation substrate, spray the absorbent paper with nutrient solution (wet), and then evenly spread the soaked seeds on the seedling tray with a thickness of 1.5 cm. The seedling tray should be placed in a well-ventilated place and properly protected from light;

3. Spraying: after sowing, the nutrient solution of the sprout is diluted by 200 times, and sprayed 1 time every day, and sprayed 2-3 times every day after the sprout grows upright;

4. Management: Generally, the production of sprouts requires a temperature of 20-25℃. Among them, the required temperature of radish seedlings and spruce seedlings is 17-20℃, and the required temperature of Toona sinensis seedlings is 22-25℃;

5. Harvesting: the germinated vegetable nutrient solution is sprayed 2-3 times every day as usual, and can be harvested on the seventh day after sowing. The sprouted vegetables are tender and fragrant.

Types of sprouts

1, soybean sprouts

People advocate eating soy products because most of these substances are degraded and destroyed during soybean germination. The utilization rate of soybean sprouts in protein is about 10% higher than that of soybeans. In addition, raffinose can't be absorbed by human body, and the substances that are easy to cause abdominal distension drop sharply or even disappear completely during germination, thus avoiding the occurrence of abdominal distension after eating soybeans.

In the process of soybean germination, more mineral elements such as calcium, phosphorus, iron and zinc are released due to the action of enzymes, which improves the utilization rate of minerals in soybean. Aspartic acid increased sharply after soybean germination. It is found that bean sprouts contain an interferon generator, which can induce interferon, increase antibiotics in the body, and increase antiviral and anticancer abilities in the body.

2, mung bean sprouts

Chinese medicine believes that mung bean sprouts are cool, sweet and non-toxic, and can clear away heat, regulate the five internal organs, relieve all kinds of toxins, induce diuresis and remove dampness, and are used for excessive drinking, damp-heat stagnation, anorexia and physical weakness. Patients with hypertension and coronary heart disease can often eat vegetarian fried mung bean sprouts in summer. Folk use mung bean sprouts to stew crucian carp to treat breast milk. Squeeze mung bean sprouts and add sugar instead of tea to treat urinary tract infection, red fever and frequent urination. Containing cellulose, it is safe and effective for constipation of the elderly and children if fried with leeks or cold salad.
