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 on the natural enemies of Solanum echinacea

Embodiment Construction

[0032] The alternative control experiment on Solanum erythroectoris showed that through suitable planting time, reasonable planting methods and scientific management methods, planting Elymus and wheatgrass in the natural grassland ecosystem invaded by Solanum erythrophyllum can effectively The purpose of curbing the invasion and spread of Solanum nigrum. The technology of preventing and controlling the invasion of Solanum erythraeum into the ecosystem is a combination of planting Elymus and wheatgrass after site preparation, and the integration of ecosystem management technology. The present invention is described in further detail by the following examples.

[0033] 1. The removal technology of Solanum nigrum before bio-alternative treatment

[0034] 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...

Abstract

The invention belongs to control methods of the ecological system, and particularly relates to a method for restraining Solanum rostratum from invading the natural ecological system. According to the method, Elymus dahuricus and wheatgrass are reasonably used for restraining the Solanum rostratum, and invasion of the Solanum rostratum is effectively controlled through the modes of deep ploughing, fine raking, leveling, compacting after sowing, irrigating and after manuring. According to the method, through reasonable matching of the Elymus dahuricus and the wheatgrass and matched scientific planting management, the Elymus dahuricus and the wheatgrass compete with the Solanum rostratum through the growth advantages of the Elymus dahuricus and the wheatgrass, the invasion behavior of the Solanum rostratum in a natural grassland is continuously and effectively restrained, and a guarantee is provided for replacing and preventing alien invasive species such as the Solanum rostratum.

Description

【Technical field】 [0001] The invention relates to an ecosystem control method, in particular to a method for using Elymus and / or Wheatgrass to prevent and contain Solanum solanum from invading natural ecosystems. 【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, Mikaniamicrantha, and Spartina anglica, which have already affected the biodiversity of my country. , ecological system security, regional economic development, and even caused great harm to human society. [0003] Solanum rostratum Dunal (Solanum rostratum Dunal), also known as Kansas thistle and yellow-flowered nightshade, is a kind of exotic harmful plant with potential serious harm that deserves high attention. The plant is a herbaceous plant of the family Solanaceae, native ...
