What are the requirements for germination containers used in traditional bean sprout production?

There are many kinds of germination containers used in traditional bean sprout production, but they must be selected according to the production nature (self-feeding or commercial production), production capacity and economic conditions. Generally, when the production is self-sufficient or the output is low, clay pots can be used, and when the output is large, clay jars or crocks can also be used. But no matter what kind of container is used, the bottom should be provided with drainage holes, and the container should be clean, oily and salty. According to experience, a container with a height of 65-70 cm can hold about 5 kg of mung beans or 10 kg of soybeans (dry seed weight). In addition, in some places in the south, cement ponds are also used as germination containers, usually with the length, width and height of 105cm× 105cm× 70cm. The inner chamber is semicircular, with a grate at the bottom (which can strengthen ventilation and drainage) and a drainage door at the bottom. According to the production practice, such a cement pool can generally put about 17.5 kg of mung beans or about 25 kg of soybeans (dry seed weight).

In addition, when selecting containers, we should also pay attention to the fact that the volume should not be too large or too small. When the volume is too large, it is often difficult to spray water evenly and thoroughly. The breath heat of bean sprouts in containers often causes the temperature of bean sprouts to rise because they can't be taken away by water, and then causes diseases such as heat injury. On the other hand, if the volume is too small, not only the production efficiency is low, but also the heat preservation is not easy, which will adversely affect the production.
