Embodiment Construction

[0014] The methods in the examples are conventional planting methods unless otherwise specified. The technology of preventing and controlling the invasion of Solanum erythrae into the ecosystem is a combination of planting sweet-scented clover + wheatgrass + Leymus 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 ...

Abstract

The invention discloses a method for controlling solanum rostratum by pasture combination. According to the method, the pasture combination of sweet clover, wheatgrass and Chinese wildrye are used to prevent invasion of solanum rostratum; the pasture combination is planted in the easily-invaded natural grassland ecosystem in order to continuously control invasion of solanum rostratum in many years. The sweet clover is a type which can resist solanum rostratum in the invasion habitat, grows in the grassland that solanum rostratum likes and has growth advantage in struggle for existence; the wheatgrass and Chinese wildrye can continuously inhibit growth of solanum rostratum in many years after alternative treatment; due to plantation, rational arrangement and scientific management, the sweet clover pasture combination can play a role in easily-invaded solanum rostratum and invaded ecosystem, inhibit solanum rostratum from quickly growing in natural grassland to occupy space continuously and effectively, and provide basic guarantee for preventing and sustainably treating invasion of alien invasive species such as solanum.

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...
