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

Abstract

The invention discloses a submerged plant planting matrix and a device utilizing submerged plants to restore eutrophic water. The submerged plant planting matrix comprises raw soil, rubble and coconut chaff. The raw soil, the rubble and the coconut chaff are mixed according to the weight ratio of (0.5-1.5): (0.5-1.5): (2-5), the planting matrix is beneficial for plant growth and has an ecological restoration function. The device utilizing the submerged plants to restore the eutrophic water comprises planting boxes, submerged plant planting layers, submerged plants, pull ropes, fixing piles and pulleys; the device has the good effect of restoring the eutrophic water, and is firm in structure, capable of being applied to the eutrophic water environment with low water transparency, frequent water level changes, much nature convulsion, hard bottom materials and the like which are bad for growth of submerged plants, wide in application range and high in adaptability.

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...
