Problems solved by technology

So far, countries around the world have carried out various methods including physical, chemical, biological and integrated management to eradicate and control Spartina alterniflora: Although physical methods have less impact on the environment, physical control must be fully considered The frequency, intensity, season and other factors can effectively exert its control effect. For example, by manually removing Spartina alterniflora, the workload is huge. If no further measures are taken afterwards, it will regerminate and return to its original state after 3 months ( 1-3m high), so the cost of control is generally relatively high; chemical methods are fast and effective, and are suitable for large-scale control, but the use of herbicides usually only removes the part above the surface, and will cause certain environmental pollution to coastal areas. The restoration of tidal flat animals and plants has brought negative effects, and the cost of production and application is also high; biological control method is an effective method for long-term control of the spread of invasive alien weeds, and the suitable natural enemies of Spartina alterniflora are insects, parasites and pathogenic bacteria, etc., but Biological control is still in the experimental stage, and the ecological consequences caused by the introduction of natural enemies are difficult to control

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] The present invention shows a kind of method utilizing the ecological succession measure of habitat restoration to control Spartina alterniflora, comprising the following steps:

[0028] 1) Physically remove Spartina alterniflora and garbage in the tidal flat area;

[0029] Among them, manual cutting or weeding equipment can be used to cut the stems of Spartina alterniflora growing on tidal flats; for sandy tidal flats, use a rotary tiller to carry out rotary tillage on the surface soil where Spartina alternif...

Abstract

The invention discloses a method for treating spartina alterniflora by using habitat restoration ecological succession measures. The method utilizes the excellent growth characteristics of pioneer mangrove forest species, the growth speed of the pioneer mangrove forest species exceeds that of spartina alterniflora in a short time and the pioneer mangrove forest species is quickly closed, so that the growth of the spartina alterniflora is inhibited, the growth and spreading of the spartina alterniflora are controlled, an arbor, shrub and vine replacement plant multi-layer community is gradually formed, a coastal zone three-dimensional composite ecological system is finally constructed, and therefore the purpose of treating the spartina alterniflora is achieved; and the method overcomes the defects of physical, chemical and biological prevention and control of spartina alterniflora in the prior art, avoids pollution caused by chemical control of foreign species and ecological risks possibly caused by control of natural enemies, saves time and labor, is good in prevention and control effect, achieves large economic and ecological benefits, and is one of the best ways for controlling harm of foreign invasive plants.

Description

technical field [0001] The invention relates to the technical field of Spartina alterniflora control, in particular to a method for controlling Spartina alterniflora by using ecological succession measures for habitat restoration. Background technique [0002] Spartina alterniflora is a perennial gramineous plant in intertidal tidal flats. It is native to the coastal intertidal zone along the mid-latitude Atlantic coast of North America; it looks like a reed, with tall plants and thick stems. The height is generally 1.2-3.5m, and the base diameter 0.5-1.5cm, and the diameter of the thick individual is more than 1.0cm; the root system is developed, mainly concentrated in the sediment at a depth of 0-30cm, and some can reach 50-100cm. Spartina alterniflora withers in autumn and winter. At the same time, it can reproduce both sexually by seeds and asexually by root tillers. It is a salt-tolerant and flood-resistant species suitable for growing on a wide beach from the lower par...
