Embodiment 1

[0020] A planting substrate for submerged plants is prepared by mixing raw soil, steel slag and rice husk in a weight ratio of 0.6:0.6:4. The raw soil is excavated from the deep layer of the original bare land without any development and utilization and does not contain plant roots and humus. The diameter of the steel slag is less than 1cm.

Embodiment 2

[0022] A planting substrate for submerged plants is prepared by mixing raw soil, steel slag and rice husk in a weight ratio of 1.8:1.8:8. All the other are with embodiment 1.

Embodiment 3

[0024] A planting substrate for submerged plants is prepared by mixing raw soil, steel slag and rice husk in a weight ratio of 1.2:1.2:6. All the other are with embodiment 1.

Abstract

The invention belongs to the water body eutrophication restoration technical field, and specifically relates to a plantation matrix favorable for benthophyte plantation and having water environment restoration effects; the plantation matrix is formed by blending the following materials according to weight ratio: immature soil, slag and rice husk by (0.6-1.8): (0.6-1.8): (4-8). The matrix also comprises ceramsite and reed rods; the weight ratio between the reed rods and the immature soil is (0.8-1.2):1; the weight ratio between the ceramsite and the immature soil is (0.6-0.8):1. The Benthophyte plantation matrix is suitable for benthophyte seedling, young shoot and seed propagule, thus greatly improving the benthophyte survival rate, and the matrix is very suitable for pondweed and Hydrilla verticillata growth.

Description

technical field [0001] The invention belongs to the technical field of water body eutrophication restoration, and in particular relates to a planting matrix which is beneficial to the planting of submerged plants and has a restoration effect on the water environment. Background technique [0002] In recent years, with the development of industry and the increase of urbanization level, a large amount of pollutants such as nitrogen and phosphorus have been discharged into the water environment. Eutrophication of water body is highly valued by the state. Restoring and rebuilding the water ecosystem is one of the main contents of water eutrophication restoration. In the prior art, using aquatic plants to restore and improve water bodies is a more and more widely used water body trophic restoration technology. However, how to make aquatic plants grow better in eutrophic water bodies and play a role in water body restoration is still a difficult problem at present. Contents of...
