Method for competition regulation by adopting phragmites australis at airport and spartina alterniflora

Abstract

The invention discloses a method for competition regulation by adopting phragmites australis at an airport and spartina alterniflora. The method comprises the following steps: the spartina alterniflora is collected in in-situ soil, and the phragmites australis is collected at the airport and transplanted to a laboratory; a pot experiment is adopted, a PVC material flowerpot with a diameter of 20 cm, a height of 30 cm and a sealed bottom is selected as an experimental vessel, soil used in the experiment is original soil of Tianjin airport, two plants are transplanted in each flowerpot, and eachspot contains a spartina alterniflora single species, a phragmites australis single species, or mixed species of spartina alterniflora and phragmites australis, wherein a mixing weight ratio of the spartina alterniflora to the phragmites australis is 1:1; and in October, plant heights, basic diameters and node numbers of the spartina alterniflora and the phragmites australis are measured, all aboveground parts are harvested and brought back to the laboratory for weighing, and drying is performed at temperature of 80 DEG C to a constant weight. The method disclosed by the invention shows thatthe spartina alterniflora has a significant inhibitory effect on the phragmites australis.

Description

technical field [0001] The invention belongs to the technical field of ecological safety, and relates to a method for using reeds and Spartina alterniflora in airports to carry out competition regulation. Background technique [0002] Plant community is a regular combination of plants in a certain area, in which there is a certain ecological relationship between plants and plants, and between plants and the environment. The result of the combination can form a certain appearance and structure. Plant species components, and can form the plant environment within the community. Due to different climatic conditions and habitat conditions, different plant communities are formed, and each community has its own unique species, hierarchy, structure and appearance. The hierarchical structure of the community is more complex and the species are rich, such as tropical rain forest; under the harsh and harsh conditions of the habitat, only a few plants can adapt, and the community struc...

Problems solved by technology

As a part of the airport ecosystem, the ground cover plant community not only beautifies the environment, regulates the micro-ecological climate in the airport, but also has the functions of absorbing water and melting snow, but it also has shortcomings: insects, rodents, hares and a lot of soil The organisms provide grass seeds and habitats, thereby attracting various birds, especially raptors, pigeons, shorebirds, gulls, etc., to feed and rest at the airport

However, there have been no reports on the competition and regulation of airport plant communities by scholars, and they are limited to simple surveys of airport vegetation resources, and have not conducted deeper research on airport vegetation.
