Problems solved by technology

[0006] At present, most of the control methods of Solanum erythrophyllum are manual extraction, mechanical and chemical control, etc., but manual extraction is time-consuming and laborious, and the operability is not strong in large-scale areas, and the residual roots and stems of Solanum erythrophyllum under mechanical control still remain New seedlings can germinate, but the success rate of control is not high; using herbicides such as paraquat and glyphosate to carry out chemical control can make the Solanum nigrum plant reach a higher mortality rate, but a large amount of pesticides will cause serious damage to the ecological environment. big pollution
However, there is no report about the natural enemies of Solanum echinacea

Embodiment Construction

[0031] The experiment on the alternative control of Solanum erythroglis showed that through suitable planting time, reasonable planting methods and scientific management methods, planting alfalfa in the natural grassland ecosystem invaded by Solanum erythrophyllum can effectively curb the Purpose of nightshade invasion and spread. The technology of preventing and controlling the invasion of Solanum solanum in the ecosystem is an integration of the introduction of alfalfa after soil preparation and the integration of ecosystem management technology. The present invention is described in further detail by the following examples.

Abstract

The invention belongs to a control method of an ecological system and specifically relates to a method of ecologically restoring degraded grassland invaded by solanum rostratum by utilizing perennial grasses. The invention provides the method of ecologically restoring the degraded grassland invaded by solanum rostratum by utilizing perennial grasses. The method effectively controls invasion of solanum rostratum by seeding alfalfa in early spring through deep ploughing, fine harrowing, leveling, suppressing after seeding, irrigating and topdressing, so that guarantee is provided for substituting and preventing the alien invasive specie solanum rostratum.

Description

【Technical field】 [0001] The invention relates to an ecosystem control method, in particular to a method for using perennial herbages to ecologically restore Solanum solanum invading degraded pastures. 【Background technique】 [0002] Alien biological invasion has become a common concern all over the world. With the rapid development of international trade and tourism, biological invasions are intensifying in my country, such as the invasion of exotic plants such as Eupatorium adenphorum (Eupatorium adenphorum), Mikania micrantha (Mikania micrantha), and rice grass (Spartina anglica). Biodiversity, ecosystem security, and regional economic development have even caused enormous harm to human society. [0003] Solanum rostratum Dunal (Solanum rostratum Dunal), also known as Kansas thistle and yellow-flowered nightshade, is an exotic harmful plant that deserves high attention and has potential major hazards. The plant is an annual herb of the family Solanaceae, native to North ...
