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

[0029] Alternative control experiments on Solanum nigrum show that through suitable planting time, reasonable planting methods and scientific management methods, Satawang and / or Brome awnless can be planted in natural grassland ecosystems invaded by Solanum solanum , can effectively curb the invasion and spread of Solanum erythrosum. The technology to prevent and control the invasion of Solanum nigrum into the ecosystem is a combination of planting Satawang and / or brome awnless after site 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 ecological system controlling methods, and particularly relates to a method for ecological remediation of meadows invaded by Solanum rostratum Dunal. The method effectively controls the invasion of Solanum rostratum Dunal by means of deep ploughing, fine harrowing, leveling, pressing after sowing, irrigation and topdressing. According to the method, erect milkvetch and awnless brome are combined reasonably to resist Solanum rostratum Dunal by means of the growth advantages of erect milkvetch and awnless brome together with scientific sowing management, the invasion of Solanum rostratum Dunal in natural meadows is inhibited continuously and effectively, and a guarantee is provided for replacing and preventing the alien invasive species Solanum rostratum Dunal.

Description

【Technical field】 [0001] The invention relates to an ecosystem control method, in particular to a method for preventing and curbing Solanum nigrum from intruding into a natural ecosystem by using Satawang and / or Bromegrass. 【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, Mikania micrantha, Spartina anglica, etc. 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 a herbaceous plant of the family Solanaceae, native to North America, and has spread throug...
