2. Description of the Related Art In general, water supply systems for bean sprouts include:
Shower type, 2. Spray type, 3. There are three methods of flooding, shower and spray are ideal for large-scale production of sprouts under the principle of natural farming, that is, without adding any chemical agents, artificial ethylene, nitrogen, antibiotics or fertilizer. Instead, when cultivated in a flooded manner, sprouts of relatively stable quality can be obtained. However, generally, flooded cultivation boxes have the disadvantage of relatively large water consumption,
In addition, when stacked in a multi-layer type, it is difficult to control the water supply amount and water supply time with a single water supply device, and the water temperature rises when the water that has passed through the upper box body flows to the lower box body. There was a discrepancy between the quality of the sprouts cultivated in the lower box and the lower box.

In growing bean sprouts, depending on the type of beans, the amount of water required in each of the soaking process (soaking the seeds in water), germination (promotion of germination), and germination (growing of sprouts) during the cultivation process is determined. Due to the different water supply intervals, in order to complete the above three processes in the same container, that is, without changing the cultivation environment, a new sprouts cultivation method and the design of an automatic water supply and drainage system are necessary. At the same time, save time, labor and water,
The cultivation time must be able to be shortened, and cultivation by the three-dimensional farm method is considered to be capable of reducing production costs and improving competitiveness in the market.

The present inventor has already obtained a utility model registration No. 118528 "Equipment for removing the root of a sprouts in a fixed direction" and a utility model registration No. 85216806 in Taiwan. Applying for.
