Culture system for duckweed starch enrichment

Abstract

This invention discloses a cultivation system for promoting starch growth in duckweed. The system includes a duckweed cultivation device, a starch growth promotion device, and a harvesting device. The duckweed cultivation device is configured to allow multiple duckweed plants to multiply in a cultivation space for a first cultivation period of several days, increasing the number of duckweed plants to a desired quantity. The starch growth promotion device is configured to allow the multiple duckweed plants to multiply in a starch growth promotion space for a second cultivation period of several days, resulting in multiple high-starch duckweed plants. The harvesting device is configured to harvest the multiple high-starch duckweed plants.

4. The aquaculture system for promoting duckweed starch growth as described in claim 1, wherein, The starch growth promoting device includes at least one second partition, which is disposed in the starch growth promoting space to divide the starch growth promoting space into multiple starch growth promoting regions.

5. The aquaculture system for promoting starch growth in duckweed as described in claim 1, wherein, The duckweed aquaculture equipment includes a first injection unit and a first discharge unit; the first injection unit is connected to and configured to inject the first aquaculture solution into the duckweed aquaculture space, and the first discharge unit is connected to and configured to discharge the first aquaculture solution; wherein, the starch growth promoting equipment includes a second injection unit and a second discharge unit; the second injection unit is connected to and configured to inject the second aquaculture solution into the starch growth promoting space, and the second discharge unit is connected to and configured to discharge the second aquaculture solution.

6. The aquaculture system for promoting duckweed starch growth as described in claim 1 further includes: A first monitoring device is installed in the duckweed aquaculture equipment. The first monitoring device is configured to detect the first aquaculture liquid in the duckweed aquaculture space to obtain a first detection data. And a second monitoring device, which is installed in the starch growth promoting device, the second monitoring device being configured to detect the second culture liquid in the starch growth promoting space to obtain a second detection data.

7. The aquaculture system for promoting duckweed starch growth as described in claim 1, wherein, The starch growth promoting device further includes: a plurality of second partitions, wherein one of the second partitions is configured to divide the starch growth promoting space into a space having a circulation channel, and another portion of the second partitions is disposed in the starch growth promoting space and connected to one of the second partitions; and a driving element, which can be disposed in the starch growth promoting space and located between the other portion of the second partitions, the driving element being configured to drive the second culture liquid in the starch growth promoting space to flow in a specific direction.

8. The aquaculture system for promoting duckweed starch growth as described in claim 1, wherein, The duckweed aquaculture equipment includes a first injection unit, a sprinkler, and a first discharge unit; the first injection unit is connected to the duckweed aquaculture space and configured to inject water; the sprinkler is located above the duckweed aquaculture space and configured to spray a nutrient solution into the duckweed aquaculture space and mix it with the water to form the first aquaculture solution; the first discharge unit is connected to the duckweed aquaculture space and configured to discharge the first aquaculture solution from the duckweed aquaculture space.

9. The aquaculture system for promoting starch growth in duckweed as described in claim 1, further comprising a transfer unit disposed between the duckweed aquaculture equipment and the starch growth promotion equipment, the transfer unit being configured to transfer at least a portion of the plurality of duckweed from the duckweed aquaculture space to the starch growth promotion space; wherein, A sprinkler is installed above the transfer unit.

10. The aquaculture system for promoting starch growth of duckweed as claimed in claim 1, further comprising a transfer unit and a distribution unit, the transfer unit being disposed between the duckweed aquaculture equipment and the distribution unit, the transfer unit being configured to transfer at least a portion of the plurality of duckweed from the duckweed aquaculture space to the distribution unit, the distribution unit having a distribution outlet being switchably connected to the starch growth promotion space.

11. The aquaculture system for promoting duckweed starch growth as described in claim 10, wherein, The starch growth space has multiple starch growth zones, and the distribution unit has a moving device configured to selectively connect the distribution outlet to one of the multiple starch growth zones; wherein a sprinkler is provided above the distribution unit.
