Embodiment 1
[0028] see figure 1 and figure 2 , the floating bed of embodiment 1, including four floating bed units, each floating bed unit includes a main body frame and a polyethylene net 2. Wherein, the main frame includes four PVC pipes 1 and four PVC elbows 4, the PVC pipes 1 and the PVC elbows 4 are surrounded by a square frame, and the side length of the main frame is 50cm×60cm. A polyethylene mesh 2 is laid inside the hollow of the main frame, and the polyethylene mesh 2 is fixed inside the main frame by the first nylon cable tie 3 . The mesh diameter of the polyethylene mesh 2 is 2 mm. The ground millet is inserted and planted on the polyethylene net 2 .
[0029] The four floating bed units are connected into strips by binding the main frames of the two left and right adjacent floating bed units with the second nylon cable tie 5 .
[0030] In Embodiment 1, preferably, the diameter of the PVC pipe 1 is 5 cm.
[0031] It should be noted that the calculation of the side length ...
Embodiment 2
[0034] Take a goose farm in Guangdong as an example: the goose farm has three goose houses, each with an area of 250 square meters, and each building has 600 animals, and there are 3 ponds in the goose sports field, namely water fowl sports waters, each with an area of 500 square meters; the waste water pond One, namely the waste water pool, has an area of 1000㎡.
[0035] Present embodiment 2 implementation process, its steps are:
[0036] 1. Breeding millet seedlings and breeding, first use the land beside the pond to breed millet by cuttings, normal maintenance and management, when the plant height of millet is 70-90cm, cut the branches of millet as a floating bed unit building materials;
[0037] 2. Floating bed planting of ground millet: the present embodiment 2 takes the floating bed of embodiment 1, cuts the ground millet stalk into segments with 2-3 nodes and inserts them in the mesh of polyethylene 2 of the floating bed 20-30 ground-paving millet stem nodes are...
