Removing and ecological remediation method for harmful submerged plant in explosive growth

Abstract

The invention discloses a removing and ecological remediation method for harmful submerged plants in explosive growth. The removing and ecological remediation method comprises the following steps: cutting the harmful submerged plants and forming stubbles of the harmful submerged plants; using a covering to cover the stubbles; and after continuously covering, removing the covering when seedlings of the harmful submerged plants do not grow and seeds of the harmful submerged plants are not survival at the positions of the stubbles, and using proper submerged plant seeds or varieties to perform ecological remediation. The method has the benefits of being pollution-free, quick in effect, convenient, efficient, environment-friendly.

Description

technical field [0001] The invention relates to the technical field of ecological environment protection, in particular to a method for removing and ecological restoration of explosively growing harmful submerged plants. Background technique [0002] In recent years, in water bodies in many parts of our country, harmful submerged plants (such as weeds) have frequently appeared to explode and grow, which seriously affects the normal operation of ships and water landscapes, and also brings great harm to the aquaculture and tourism industries. loss. Practice has proved that for harmful submerged plants that tend to explode, the sooner measures are taken, the easier it is to curb their outbreak and spread. Once it shows explosive growth, the difficulty of control and investment may increase exponentially. In recent years, relevant departments have invested a lot of manpower, material and financial resources in manual salvage and cleaning of these flooded submerged plants. But...

Problems solved by technology

In recent years, relevant departments have invested a lot of manpower, material and financial resources in manual salvage and cleaning of these flooded submerged plants. But the long-term effect is not significant, because this kind of plants often have a huge soil seed bank, and the regeneration ability of the plants is also very tenacious. After a period of time after cleaning, they can resume growth again, or even flood

Therefore, it is generally difficult to cure or remove with the above-mentioned methods of the prior art, forming an endless cycle of constantly clearing up and constantly recurring

It is not advisable to use chemical methods, because of the dilution of the water body, the dosage of chemical drugs must be increased enough to receive the weeding effect, and this will certainly increase the pollution of the water body and may endanger the survival and health of other organisms in the water body

So far, no effective removal and ecological restoration methods have been found for this kind of harmful submerged plants showing explosive growth, which has become a very difficult ecological problem that needs to be solved urgently
