Method for reestablishing river submerged plant group

Abstract

A method for quickly establishing a river submerged plant group is designed for the technical field of environmental engineering. For damaged river ecosystem, the combination of selected submerged plants, such as hornwort-waterweed, hornwort-eel grass and the like, are planted in plant growing areas in different shapes. A special transplanting way is adopted during the planting process; a little soil is remained at the root of each plant and a little clay is manually kneaded at the outside of the root to form a sphere; and finally, an organic net is sleeved to the sphere so that the shape can be kept for a long time; next, a small-mesh fishing net is stretched at the front end of each plant growing area so as to reduce the impact force caused by water flow on the plants; and the finishing net is removed after the plants are transplanted for a while; therefore, a submerged plant group is established.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to a method for rapid restoration of submerged flora. Background technique [0002] With the rapid development of the economy, people are more and more frequently asking for resources from nature, reclaiming land from the sea, cutting down forests wantonly, and building dams, all of which have caused serious damage to the ecology. In our country, due to the rapid urbanization process, the urban population has exploded, and some factories have also surged, and most of them are built along the river. A large amount of domestic waste and industrial waste are discharged into the river without proper treatment, resulting in eutrophication of the river water, blackening and smelling of the river water, and the extinction of various organisms that originally existed in the river due to drastic changes in the environment. Due to this man-made reason, the river...

AI Technical Summary

Problems solved by technology

For the reconstruction of submerged flora, the following problems are faced: (1) The newly reconstructed submerged flora is easily washed down by the water flow and cannot be fixed for a long time, resulting in failure of reconstruction

(2) High mortality of plant seedlings

At present, the basic method is to transplant submerged plants from healthy rivers to the treated rivers, but it still cannot solve the above problems
