Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, the embodiment of the present invention provides a planting structure of submerged plant seeds in a river channel with water, the planting structure mainly includes a degradable non-woven bag 11, a 3D mesh pad 12, ecological gravel 13, and sometimes may further include a fixing column 14.

Seeds of the submerged plants are uniformly sown on the degradable non-woven bags 11, the degradable non-woven bags 11 with the seeds are covered with 3D net pads 12, and ecological gravels 13 are paved on the 3D net pads 12. The 3D net cushion 12 is made of nylon and has a long-term three-dimensional net cushion structure, so that a sufficient climbing and shrinking space is provided for the plant root system, and the 3D net cushion is not easy to decompose and has no secondary pollution.

Preferably, the 3D net pad 12 is fixed by fixing columns 14, and the lower ends of the fixing columns 14 vertically penetrate the 3D net pad 12 downwards and then are inserted into the bottom silt layer 15 of the river channel to fix the 3D net pad 12. The interval of the fixed columns 14 is determined according to the speed of water flow and the depth of water, and the fixed columns can be taken out after the submerged plants are completely and firmly rooted.

The ecological gravels 13 on the 3D net pad 12 can be further filled into a degradable net bag, and the pore diameter of the degradable net bag is smaller than the particle diameter of the ecological gravels 13. The amount of the ecological gravel 13 is determined according to the depth of water in a river channel, the ecological gravel 13 can prevent the 3D net cushion 12 and the plants from floating upwards on the one hand, and gaps among the paved gravels can form an anoxic anaerobic state on the other hand, so that the ecological gravel has a denitrification effect on a water body, and microorganisms are gradually attached to the surfaces of the gravels, so that a biomembrane can be formed, organic matters are decomposed, and the water quality is purified, and therefore, the submerged plants and the ecological gravel purify water together.

The construction steps of the planting structure of the submerged plant seeds in the water-carrying operation of the riverway are as follows:

firstly, uniformly scattering seeds of submerged plants on a degradable non-woven bag 11, and degrading the non-woven bag after the seeds germinate and grow;

secondly, the non-woven bag with the seeds is covered with the 3D net pad 12, and the submerged plants which germinate and grow form root systems with disc root joints on the 3D net pad 12, so that the stability and the impact resistance are higher;

thirdly, laying ecological gravels 13 on the 3D net cushion 12, placing the ecological gravels 13 into a degradable net bag, wherein the aperture of the net bag is smaller than the size of the ecological gravels, the amount of the ecological gravels 13 is determined according to the depth of water in a riverway, on one hand, the ecological gravels 13 can prevent the 3D net cushion 12 and plants from floating upwards, on the other hand, gaps among the laid gravels can form an anoxic anaerobic state, the ecological gravels have a denitrification effect on a water body, and microorganisms are gradually attached to the surfaces of the gravels, so that a biomembrane can be formed, organic matters are decomposed, and water quality is purified, and therefore, the submerged plants and the ecological gravels purify water together;

and fourthly, fixing the 3D net pad 12 through the fixing columns 14, wherein the intervals of the fixing columns 14 are determined according to the speed of water flow and the depth of water, and the fixing columns can be taken out after the submerged plants are completely and firmly rooted.
