Embodiment 1

[0032] In the second step, the frame 8 is an aluminum alloy frame; in the third step, the plant 10 is a canna that can grow secondary and tertiary root systems; in the fourth step, the canna, the combined packing sheet string array 11 and the frame 8 are immersed in the In the water body; in the fifth step, the canna grows secondary and tertiary root systems 9, the secondary root system passes through the hole 3, and the tertiary root system grows entangled with the fiber 1; in the sixth step, the canna is firmly fixed in the combined packing sheet string array 11 on.

[0033] This fixation technology was used in the implementation of the biological grid to control the Liwa River on the campus of East China Normal University, and the canna planted did not break or fall during the typhoon. The secondary and tertiary root systems of the canna extend to the adjacent composite packing string, and the array of the composite filler string forms a cross-fixation of the canna.

Embodiment 2

[0035] In the second step, the frame 8 is a PVC pipe frame; in the third step, the PVC pipe frame is floating on the water; in the fourth step, the plant 10 is a ryegrass that can grow secondary and tertiary root systems; in the fifth step , Ryegrass grows secondary and tertiary root systems 9, the secondary roots pass through the holes 3, and the tertiary roots grow entangled with the fibers 1. In the sixth step, the ryegrass is firmly fixed on the combined packing sheet string array 11.

[0036] Ryegrass is firmly fixed on the combined packing sheet string array 11, and floats on the water surface of the treatment water body together with the frame 8 to treat the water quality of the water body.

Abstract

The invention discloses a plant fixing method in the water body in the plant fixing and environmental protective technical domain, which comprises the following steps: adopting present combined filling piece as substrate to fix the plant; placing the plant in the combined filling piece immersed in the water body directly; entangling the two and three graded beard roots and the fiber of the combined filling piece tightly; fixing the plant on the combined filling piece directly. The invention has fastened fixing, light-weight substrate, large contact area of water body and plant root and good fluidity of water among root, which is fit for fixing plant in the water body to harness water quality.

Description

Technical field [0001] The invention relates to a method for fixing plants in a water body, and belongs to the technical field of fixing plants in a water body and environmental protection. Background technique [0002] As we all know, the substrate for fixing plants in the water body is soil, gravel, etc., and it can also be bagged pine needles, polystyrene foam, and bamboo. The use of these substrates to fix plants in artificial floating islands, artificial wetlands, biological fences and other devices will hinder the flow of water between plant roots, reduce the contact area between roots and water, and fail to give full play to the ecological role of plant roots. At the same time, these traditional The ability of plant fixation methods to fix plants is related to the fixation ability of the substrate itself. Substrates such as soil or pine needles in artificial floating islands and biological fences are easy to scatter. After the plant biomass reaches a certain level, the wei...
