Patent Description:
In plant factories and hydroponic plants, after the hydroponic seedlings are afforested in the nursery room, manual or machine work is required to first fill planting cups on a planting plate, then tear sponge blocks into sponge strips, then tear sponge strips into sponge blocks, and then grip the sponge blocks directly and insert into the planting cups.
