When selecting seeds, you can soak them in water first. Generally, the vitality of floating seeds is not strong, so it is recommended to give up. Secondly, the rounder it looks, the better, and it has a certain luster. It is generally best to soak for a period of time before planting, and the time is controlled at about 5 hours. If floating is found after soaking, all should be taken out and drained. Keep the seeds moist before sowing, which is of great benefit to keep the seeds alive.

Step 2 sow seeds

It is not recommended to plant bean sprouts in soil, because the density of bean sprouts is very high and it is not convenient to manage. It is suggested to choose small square containers for planting. The container does not need to be too big, generally 40*50 cm in size. When sowing, it is usually placed directly on the soil surface, so that it can be buried a little, and it should be blocked with a cover to keep it moist. Most bean sprouts grow on water and do not need fertilization.

3. Temperature

This is an important place for bean sprouts to grow, and the temperature directly affects the development of bean sprouts. Generally, the temperature after sowing is controlled at 65438 08℃. Because the beans are just beginning to recover at this time, such a temperature is most suitable for them to germinate. The temperature should be controlled at about 23℃ after the seeds are broken and germinated. At this time, bean sprouts are in the growth period, and this temperature is most conducive to the growth of bean sprouts.

Step 4: Moisture

The control of water directly affects the harvest of bean sprouts, because the whole growth process of bean sprouts is maintained by water, and because of its rapid growth, it needs more water. Generally speaking, you need to shower every 5 hours or so. It is suggested to install water spraying equipment on the top of plants in large quantities, and spray it in the form of Mao Mao rain, which can reduce a lot of watering time.

5, appropriate hydration

The suitable growth temperature is about 65438 05-32℃. When the temperature exceeds 30℃, it grows fastest and has a great demand for water. Spray water more than twice a day. When the temperature is 20-30℃, spray water once in the morning and once in the evening. When the seedling height is about 10 cm, sandy soil should be kept moist and the air humidity should be moderate.

Do a reasonable water spray (the water mist can be slightly larger in the later stage) to make the bean sprouts grow healthily and rapidly, and the bean sprouts with unclean shells are basically shelled. If the humidity is not enough and the air is dry, the bean sprouts will not get wet all day, which will directly affect the product quality. When the height of 12 cm is high, we should be prepared to put green according to the temperature.
