Problems solved by technology

Among them, physical control refers to manual removal, using artificial machinery to perform carpet felling and removal. Due to the high cost of manual removal, it is not very practical for the control of Mikania micrantha; spread, but biological control has the risk of introducing new ecological crises; chemical control refers to spraying Mikania micrantha with chemical herbicides, but Mikania micrantha is prone to re-emerge after control
Therefore, for the control of Mikania micrantha, a single control method can no longer play an efficient and long-term control effect, so it is necessary to explore the comprehensive control strategy of Mikania micrantha

Embodiment 1

[0023] The control experiment was carried out in March 2017. The soil was prepared for a week outside each of the three Mikania control areas, the surrounding weeds were cleared, and the saplings of Sarcophagus spp. The width is about 2m, and 150g of compound fertilizer is applied to each sapling during planting. During subsequent management, topdressing is carried out depending on the growth situation, and 150g of compound fertilizer is applied as topdressing. The unsurviving saplings are removed in time and replanted in time. According to the amount of 10% glyphosate 1300g mixed with 35 kg of water per mu, the area for preventing and controlling Mikania micrantha was sprayed, and the stems and leaves of Mikania micrantha were sprayed with a sprayer.

[0024] After 35 days of drug efficacy, one of the three Mikania control areas was randomly selected as a control area, and the other two were used as test areas to plant sweet potatoes. In one of the test areas, the Mikania cont...

Abstract

The invention discloses a method for comprehensive prevention and control of invasive species Mikania micrantha, which comprises the following steps: (1) spraying chemical herbicides in an area for preventing and controlling Mikania micrantha, setting an isolation area around the area for preventing and controlling Mikania micrantha, and planting resistant Mikania micrantha in the isolation area Covered saplings; (2) cutting off Mikania micrantha in the control area to form a net blank area, and planting sweet potatoes in the net blank area when spraying chemical herbicides for 20 to 40 days; (3) after the sweet potatoes are harvested , inoculate dodder on Mikania micrantha in the control area of ​​Mikania micrantha. Utilizing the dual effects of the anti-covering isolation zone on the periphery of the mikania micrantha control area and the net planting area of ​​sweet potatoes in the mikania micrantha control area, the control effect of micrantha micrantha was improved. application prospects.

Description

technical field [0001] The invention relates to the technical field of prevention and control of harmful plants, in particular to a method for comprehensive prevention and control of invasive species Mikania micrantha. Background technique [0002] Mikania micrantha Kunth, also known as Eupatorium micrantha or Eupatorium micrantha, is a perennial herb or shrub-like climbing vine of the Asteraceae family, native to South and Central America, and has been widely spread to tropical regions of Asia, such as In India, Malaysia, Thailand and other places, Mikania micrantha appeared as a weed in Hong Kong, China in 1919, and was discovered in Shenzhen in 1984. Since 2008, it has been widely distributed in the Pearl River Delta region. According to statistics, as of 2009, the distribution area of ​​Mikania micrantha in my country has reached Up to 100,000 hm 2 above. This species has been listed as one of the 100 most harmful invasive alien species in the world, and it is also inclu...
