Embodiment 1-3

[0035] In June 2016, the inventor set up three 100 square meters squares on the whole island of Neilingding Island in Shenzhen (the coverage of Bauhinia powder leaf in the three squares was 35% (Example 1) and 50% (Example 1). 2), 80% (Example 3)), the Mikania micrantha in the sample was cleaned by manual cutting, and the sample was monitored for 6 months. The monitoring frequency is once a month, and the new plants of Mikania micrantha sprouting in the plot are removed after each observation and recording.

[0036] The results showed that the sample with 80% coverage of Bauhinia chinensis was in Example 3, which basically occupied the entire sample at the first follow-up monitoring, and the coverage was close to 100%. Although Mikania micrantha had a small number of new plants sprouted, The growth status is poor and does not have a competitive advantage. In the second-sixth follow-up monitoring, the number of Mikania sprouting is less than 10 plants, and Mikania micrantha has ba...

Embodiment 4

[0038] In March 2017, the inventor carried out an application experiment of using Bauhinia powder leaf to control Mikania micrantha in Shenzhen Dashahe Park. Choose a typical damage site of Mikania micrantha. The plot is about 20 meters long and 5 meters wide. The coverage of Mikania micrantha exceeds 85%. The native plant communities in the sample plot are Bougainvillea of ​​Mirabilis and Red Flower of Malvaceae. The vegetation on the ground is mainly Wedelia chrysanthemum with a coverage of about 15%. Most of the bougainvillea and red flowers have died under the cover of Mikania, leaving only the branches. In the application test, after the ground branches of Mikania micrantha were cleaned all the roots, the powder-leaf Bauhinia bag seedlings with a height of about 30 cm without roots were planted at a density of 10 plants per square meter. After the planting was completed, the root water was poured. Observe once a month thereafter, and clean up other plants that compete wit...

Abstract

The invention discloses an ecological control method for Mikania micrantha. The ecological control method for Mikania micrantha comprises the following steps: planting Bauhinia glauca seedlings in a control area of Mikania micrantha, and cultivating the Bauhinia glauca seedlings. The ecological controlmethod for Mikania micrantha utilizes the rapid growth characteristic of Bauhinia glauca to realize the purpose of inhibiting growth of Mikania micrantha through rapidly occupying ecological niches of Mikania micrantha, and effectively shortens the cultivation period. In addition, the characteristic of perennial vines of Bauhinia glauca is utilized for shortening the spacing between adjacent Bauhinia glauca, and is combined with the rapid growth characteristics of Bauhinia glauca to avoid re-invasion of Mikania micrantha, and further, ecological control of Mikania micrantha is long-lasting and sustainable, thereby effectively reducing the economic cost of ecological control of Mikania micrantha and improving the ecological control effect of Mikania micrantha.

Description

Technical field [0001] The invention belongs to the technical field of pest ecological control, and specifically relates to a method for ecological control of Mikania micrantha. Background technique [0002] Mikania micrantha is one of the ten most harmful weeds in the world. In 2001, it was listed as one of the 100 most harmful invasive species in the world by the International Union for Conservation of Nature (IUCN). At present, Mikania micrantha occurs and harms on a large scale in South China, Yunnan and other places, posing a major threat to agriculture and forestry in these areas, and greatly destroying the local ecological environment. [0003] The major harm of Mikania mikania to agriculture, forestry and ecological environment has attracted great attention. Since the 1970s, a series of researches on the prevention and control of Mikania mikania have been carried out at home and abroad. my country has achieved remarkable results in the prevention and control of Mikania.
