Submerged plant planting substrate and device for repairing eutrophic water body using submerged plants

Abstract

The invention discloses a planting substrate for submerged plants and a device for repairing eutrophic water bodies by using submerged plants. The bran is mixed according to the weight ratio (0.5~1.5):(0.5~1.5):(2~5). The planting substrate is not only beneficial to plant growth, but also has the function of ecological restoration. The device for repairing eutrophic water body by using submerged plants includes a planting box, a submerged plant planting layer, submerged plants, pull ropes, fixed piles and pulleys; the device has a good repairing effect on eutrophic water bodies and has a stable structure. It can be used in eutrophic water environment with low water transparency, frequent water level changes, many natural disasters, and hard bottom, which is not conducive to the growth of submerged plants. It has a wide range of applications and strong applicability.

Description

technical field [0001] The invention belongs to the technical field of eutrophic water restoration, and in particular relates to a submerged plant planting substrate and a device for repairing eutrophic water by submerged plants. Background technique [0002] In recent years, with the acceleration of industrialization and urbanization, a large amount of pollutants such as nitrogen and phosphorus have been discharged into lakes, reservoirs and rivers, and the eutrophication of water bodies has attracted widespread attention from ecologists and environmental experts all over the world. The eutrophication of my country's coastal waters and most of the rivers and lakes is becoming more and more serious, and its original ecological self-purification ability is gradually declining. In severe areas, it has even lost its self-purification ability. Restoring and rebuilding the water ecosystem is the key to eutrophic water body ecology. One of the main things to fix. [0003] The ulti...

Problems solved by technology

[0005] Use ropes to adjust the height of the seedling tray in the water, and use anchors or ropes to fix it on the bottom of the water or on the shore. In this way, it is easy to lower the seedling tray, but difficult to raise it, and lacks controllability

Chinese patent application CN1530336A discloses an ecological restoration method for eutrophic shallow water and small water bodies. This technology discloses a pulley lifting cultivation model for submerged plants consisting of fixed pulleys inserted on both sides of the river and flowerpots fixed by ropes. Introduction, although the device can be adjusted, but the device is poor in stability and is not suitable for environmental changes and frequent catastrophes

The restoration of submerged plants is limited by many conditions, and there are still many problems in water restoration projects
