Embodiment Construction

[0014] Unless otherwise specified, the methods in the examples are all conventional planting methods. The technology to prevent and control the invasion of Solanum thorn in the ecosystem is a combination of soil preparation and the introduction of a combination of planting C. chinensis and the integration of ecosystem management technology. The present invention is further described in detail by the following examples.

[0015] 1. Removal technology of calyx solanum before biological replacement treatment

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

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

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 present invention relates to a method for preventing and curbing the invasion of calyx solanum into natural ecosystems. Background technique [0002] Invasive alien species (IAS) refers to the introduction from the natural distribution area through intentional or unintentional human activities, which has formed self-regeneration ability in the local ecosystem and caused obvious damage to the local ecosystem or agricultural production. or affected species. Due to its huge threat to human health, ecological functions of natural ecosystems, biodiversity and benefits of agriculture and animal husbandry, invasive alien organisms have become a hot issue of global biosecurity, environment and economy, and have attracted great attention from all over the world. Invasive plants are now an economic problem and threaten natural ecosystems because the destruction of plant communities can lead to the disintegration of the foundations of entire natural ecosyste...
