Problems solved by technology

[0003] In order to solve the problem in the prior art that after a period of artificial cleaning of invasive plants, they quickly resume growth and even flood again, which is extremely difficult to control. The present invention provides a method for quickly and effectively removing invasive foreign plants in reed communities. Methods

Embodiment 1

[0014] The Spartina and Spartina alterniflora mentioned in this example belong to the same genus and belong to invasive alien plants. Their ecological habits are basically the same, and the removal and restoration measures taken for them are also basically the same.

[0015] 1) Investigate the annual high growth and horizontal expansion rates of Spartina or Spartina alterniflora and reeds under different habitat conditions in a coastal wetland in East China, analyze their suitability for the habitat, and specifically measure Habitat factors such as elevation, soil moisture, and salinity were used to obtain good habitat conditions (moisture, salinity, and elevation range) for Spartina alterniflora and Phragmites alterniflora to grow.

[0016] Based on this, formulate specific physical removal and ecological restoration programs. The general principle is to keep Spartina or Spartina alterniflora in habitats that are not suitable for the growth of reeds, but Spartina alterniflor...

Abstract

The invention relates to a method for removing invasive alien plants from reed communities, in particular to the method for removing the invasive alien plants from the reed communities. The method comprises the following steps that the alien plant distribution region is investigated, the region which is not suitable for the reed to grow is divided into a remaining region, a region which is suitable for the reed to grow is divided into a removing restoration region, the invasive alien plants in the remaining region are remained, and the invasive alien plants in the removing restoration region are subjected to cutting and short stubble remaining; the stubble remaining region is covered by plastic films with black upper surfaces until the invasive alien plants are choked to death; and the black plastic films are removed, and reed varieties with strong salt resistance and water resistance performance are planted again in the covered region. The method provided by the invention can favorable for the fast efficient and selective cleaning of the invasive alien plants, the restoration and the growth of local plants are promoted, the health and the stability of the tidal wetland ecosystem are maintained, and after the skillful use, the ecological effect of lasting political stability of the tidal wetland ecosystem can be reached.

Description

[technical field] [0001] The invention relates to a method for removing invasive foreign plants, in particular to a method for removing invasive foreign plants in reed communities. [Background technique] [0002] In recent years, in the riparian (seaside and river bank) wetlands in many areas of my country, exotic plants (especially Spartina or Spartina alterniflora) have rapidly grown and spread, and compete with native plants (such as reeds), and The phenomenon of invading or even replacing native plants has had a serious impact on the biodiversity composition, structural stability, functional operation, and landscape pattern of the local ecosystem. At the same time, it has also brought great losses to the local aquaculture and tourism industries. Most of these exotic plants (such as Spartina or Spartina alterniflora) have tenacious asexual and sexual reproduction capabilities, and they grow rapidly, and they are highly resistant to water and salt. Relevant departments hav...
