Embodiment Construction

[0014] The methods in the examples are conventional planting methods unless otherwise specified. The technology to prevent and control the invasion of Solanum erythraeum into the ecosystem is the integration of the introduction of Elymus chinensis after site preparation and the integration of ecosystem management technology. The present invention is described in further detail by the following examples.

[0015] 1. The removal technology of Solanum nigrum before bio-alternative treatment

[0016] The test site is Platform Town, Baicheng City, Jilin Province, which belongs to one of the severe epidemic areas of Solanum solanum. The ecosystem for the test is a natural grassland without large-scale vegetation coverage, and the average annual vegetation coverage is more than 70%.

[0017] In this ecosystem, the invaded plots were plowed to a depth of 20-25 cm before the emergence of Solanum erythrae in May-June of that year, and 50 kg / mu of compound fertilizer was applied as bas...

Abstract

The invention discloses a method which adopts pasture to control solanum rostratum, wherein elymus dahuricus is adopted as a plant specie for controlling the solanum rostratum invasion, is planted in the natural grassland ecosystem which is easily invaded by the solanum rostratum, and continuously controls the solanum rostratum invasion for a plurality of years. The elymus dahuricus is the plant specie which quickly grows, grows in the grassland which is preferable for the solanum rostratum to grow and has obvious advantages for struggling for existence, through introducing and planting as well as reasonable configuration and scientific management, the elymus dahuricus can completely ply the role in the ecosystem which is easily invaded and is invaded by solanum rostratum, continuously, and effectively inhibits the quick growing and space occupying invasion of the solanum rostratum in the natural grassland, so a basic guarantee is provided for substituting and controlling exotic invasive species-solanum rostratum and sustainable treating.

Description

technical field [0001] The invention relates to a method for preventing and restraining Solanum solanum from invading natural ecosystems. Background technique [0002] Invasive alien species (IAS) refers to the introduction from the natural distribution area through intentional or unintentional human activities, forming self-regeneration ability in the local ecosystem, and causing obvious damage to the local ecosystem or agricultural production. or affected species. Because of their great threats to human health, ecological functions of natural ecosystems, biodiversity, and agricultural and animal husbandry benefits, invasive alien organisms have become a hot issue in global biosecurity, environment, and economy, and have attracted great attention from all countries in the world. Invasive plants are now an economic problem and a threat to natural ecosystems because the destruction of plant communities can lead to the disintegration of the foundation of entire natural ecosys...
