Problems solved by technology

[0005] However, most of the artificial floating beds in the prior art use large-scale aquatic plants, and most of the floating beds are planting holes, which need to be filled with planting materials. The characteristics of rapid asexual reproduction of stem nodes, and the difficulty of harvesting in the later stage, are not conducive to popularization and utilization
[0006] Moreover, the main goal of the existing floating bed system is water purification, the floating bed plants need to be harvested regularly, the management cost is high, and there is little involvement in the in situ utilization of the floating bed plants

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...

Abstract

The invention discloses a method for purifying waterfowl breeding sewage through a panicum repens floating bed. The method includes the steps of planting panicum repens cuttage seedlings on the floating bed, placing the floating bed in a wastewater pool, purifying wastewater through the growth process of panicum repens and the effect of root system adsorbing microorganisms, transferring the floating bed to a waterfowl activity water domain after the panicum repens grows to a certain extent in the wastewater pool so that the panicum repens can be eaten by waterfowl and the waterfowl activity water domain can be purified by the panicum repens, establishing another floating bed for cuttage plantation of the panicum repens in the wastewater pool when the floating bed is transferred to the waterfowl activity water domain, and switching the floating bed in the wastewater pool and the floating bed in the waterfowl activity water domain in this way after the panicum repens grows to a certain extent in the wastewater pool. The aims of purifying the water and sufficiently using the plants on the floating beds can be effectively achieved; the aim of in-situ utilization of the plants of the floating beds is realized and the management cost of the floating beds is reduced by transferring the floating beds between the wastewater pool and the waterfowl activity water domain back and forth.

Description

technical field [0001] The invention relates to the technical field of ecological cultivation and planting, in particular to a method for purifying water fowl breeding sewage by using a ground millet floating bed and the floating bed using the method. Background technique [0002] At present, part of the pollution of rivers in our country comes from the discharge of aquaculture sewage. Modern waterfowl farming often has ponds and waste water ponds for waterfowl sports fields, which consume a lot of water resources and cause waste of water resources. Wastewater discharge pollutes the environment. [0003] Among them, the discharge of wastewater is generally only treated with simple filtration, and the discharge of wastewater is not up to standard and cannot be recycled. The artificial floating bed is currently a more reasonable means of restoring the water body ecology. The buoyancy of the floating bed is used to support the aquatic plants, so that the aquatic plants can obta...
