Method for efficiently treating eutrophication of water body by using soilless cress

Abstract

A method for efficiently treating eutrophication of a water body by using soilless cress is characterized in that an aquatic plant is planted and can absorb nitrogen, phosphorus and other components in water and underwater sludge, so that eutrophication components in the water body are greatly reduced, and excessive propagation of alien species such as water hyacinth in the water body is avoided. The aquatic plant is a vegetable food material and is suitable for growing in water. The method is easy to implement, can greatly protect the water resource environment, reduce the harm of alien species such as water hyacinth to a water body and other animals and plants in the water body and balance the ecological system, and is economical and more environmentally friendly.

Description

technical field [0001] The invention relates to the field of methods for controlling eutrophication of water bodies, in particular to a method for efficiently controlling eutrophication of water bodies with soilless celery. Background technique [0002] The eutrophication of the water body will lead to the overgrowth of foreign species such as water hyacinth, which will block the sunlight and lead to the death of a large number of underwater plants, which will cause the water body to be in an oxygen-deficient state, so that the bottom fish will also suffer from hypoxia. And die. If the overgrown water hyacinth is not salvaged in time, it will cover the water surface and block the river. At present, manual salvage, quicklime or copper sulfate are used to remove excessive water hyacinth and algae in the water, but manual salvage will waste a lot of manpower and financial resources, and adding quicklime or copper sulfate will pollute the ecological environment. The reproducti...

If the overgrown water hyacinth is not salvaged in time, it will cover the water surface and block the river

At present, artificial salvage, quicklime or copper sulfate are used to remove the excessively multiplied water hyacinth and algae in the water, but manual salvage will waste a lot of manpower and financial resources, and putting in quicklime or copper sulfate will pollute the ecological environment
