Production technology of soybean sprouts how to send soybean sprouts in winter

Greenhouse vegetables are the key technical means for vegetable farmers to seize the market and get more profits, but greenhouse technology is not suitable for all vegetables. Bean sprouts are the exception. The breeding of bean sprouts has relatively low requirements for the environment, and sprouts can be sent out no matter which season.

Production technology of soybean sprouts

1. Production environment. The environment of mass production of bean sprouts should be kept moist and dark, and the indoor air flow is stable, which is conducive to the production of high quality bean sprouts.

2. Production appliances. Mass production of bean sprouts is an operational specialized production, mostly flow operation, circular operation, so that soaking beans every day, accelerating sprouting, and producing bean sprouts every day, continuous turnover production. The instruments used are mostly wooden buckets, and their specifications can be divided into large, medium and small sizes. Generally, large buckets are suitable for the production of 60 kg bean sprouts, not too large. The bottom of each type of barrel is movable and can be easily removed for cleaning, disinfection and tipping of bean sprouts. In the process of production, with the elongation of bean sprouts, different specifications of buckets are used in turn, so as to improve the utilization rate of buckets. For example, on the first and second day of bean sprout production, it is first cultivated in a small barrel, then transferred to a medium barrel on the third and fourth day, and then cultivated in a large wooden barrel on the last fifth and sixth day.

3. Choose bean seed. In order to produce bean sprouts in large quantities, we should do a good job in selecting bean seeds, and it is appropriate to use fresh, disease-free and broken bean seeds.

4. Watering management. Strengthen water management, special personnel are responsible for water operation, so as to adjust and control the temperature of bean sprouts, promote the growth of bean sprouts, prevent and avoid rotten sprouts. Before each watering, the mulch such as straw bag, gunny bag or multi-layer gauze can be opened, and then tightly covered in time after watering. The frequency of watering generally drenches bean sprouts every 4 hours in summer and every 6 hours in winter.

But be careful when watering bean sprouts. The bean sprouts in each bucket must be watered thoroughly every time. Due to the large production capacity, it is necessary to have professional personnel. Engage in drenching work. meanwhile. Due to the large water consumption, it can be drilled indoors. Well water is used to pour water. Because the well water is warm in winter and cool in summer, it can be drenched directly. If you use tap water, mix it with hot water in winter and keep the water temperature around 27 ℃. In order to facilitate management, a stove should be lit indoors in winter. Specially used for watering hot water and so on.

5. Disinfection and antiseptic.

Disinfection of ① production appliances. Pay attention to the cleanliness and disinfection of utensils, and the wooden buckets used in production are often exposed to the sun to kill germs. After the barrel has been used for a long time, it should be checked and trimmed frequently, and the rotten part of the bottom should be replaced in time to prevent the growth of bacteria. meanwhile. Watering utensils and coverings should be kept clean, often disinfected with boiling water, or disinfected with lime water, that is, a water tank is often used to store lime water (the lime water does not remove the slag and let the slag sink to the bottom of the cylinder). For the disinfection of all kinds of equipment and appliances, it is required to soak and disinfect in lime water for more than 1 hour, and rinse with clean water after being fished out. All kinds of tools for producing bean sprouts should be used exclusively and should not be mixed with general cooking utensils.

Disinfection of ② bean seed. Soak the bean seeds in warm water for 6 hours, require the water surface to be 2 times higher than the bean noodles, stir several times more in the early stage of soaking, remove the seeds after soaking, soak them in 3% lime water (no ash residue is required) for 5 minutes, constantly stir, then wash them in warm water, or stir and disinfect them with 0% bleach solution for 10 minutes, immediately rinse them with warm water.

③ pays attention to the cleanliness of the water source to prevent pollution.

How to sprout soybeans in winter

1. Wash the beans and soak the beans in warm water (winter). The state of swelling of the beans after three hours. It takes 8-10 hours for beans to swell completely.

2. Drain the fully expanded beans and cover them with a moist and clean cloth.

3. Sprouting 1-2 cm on the third day, you can put some weight on the beans to make the sprouts grow. The sprouting on the fourth day has been very long.

On the fifth day, wash the bean sprouts with clean water, pick up the skins, and clean up the bad beans that do not sprout.

Matters needing attention in sending bean sprouts

1, when the bean sprouts grow to 15 mm long, watering should not leave a dead corner, in order to prevent red roots, rotten roots.

2. Master the temperature of the water, water it regularly, and use the water not suddenly hot and cold, so as to prevent the bud 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 but not stems.

4. When the bud is 50 mm long, the water temperature should be increased and the heat should be increased to prevent the bud root from blackening.

5. When the bean sprouts are ready, the water temperature of the last three times of watering should be lowered, and the sprouts should be taken out in time to prevent the bean sprouts from rotting in the middle.

Nutritional value of soybean sprouts

1. Soybean sprouts contain lower calories, higher moisture and dietary fiber, and vitamin C produced in the process of germination.

2. Soybean sprouts contain high-quality plant protein and rich minerals such as vitamin E, vitamin B1, vitamin B2, calcium, potassium, phosphorus and iron.

3. Part of the starch and protein stored in the seeds during soybean germination are decomposed under the action of enzymes and transformed into sugars and amino acids needed for their own growth, which greatly improves the utilization rate of starch and protein in beans.

In winter, soybean sprouts only need to be soaked in warm water to promote the development of beans. But for the growers who specialize in planting bean sprouts to make a profit, the planting technology and equipment need to be considered. In addition, there are some points for attention in the germination process.
