Problems solved by technology

This method belongs to the category of ecological control of Mikania micrantha, is suitable for land suitable for forests, does not have the problem of environmental pollution, and can control Mikania micrantha once and for all. The disadvantage is that its scope of use is limited
Habitat improvement methods are currently mainly used in the improvement of areas affected by Mikania micrantha, and mainly for discontinuous patch improvement, without forming shelterbelts, and other areas outside the scope of improvement are still vulnerable to disasters

Embodiment 1

[0020] During the daily management and maintenance of the plants in the growing area of ​​Mikania micrantha, it was found that compared with other tree species that were heavily covered by Mikania micrantha, the number of climbing and entangled Mikania micrantha trees was less. Plant seedlings of different tree species under two years old (about 1.5m high) in the area where Mikania micrantha is endangered, and observe for a growing season. It is found that the top leaves of all young Macaranga tunga trees are not covered, the plants are growing well, and there is no death; The leaves are all covered, and only the top seedlings that grow vertically are on the covering layer. The growth is affected to a certain extent, and there is no death; the whole plant of Yinxiang saplings is covered, and the growth is slow, but there is no death; Occasionally, a small number of leaves exposed the cover layer of Mikania micrantha, the growth was inhibited, and the mortality rate of young tre...

Embodiment 2

[0023] In August 2010, a shelterbelt pilot project was carried out in the area near the reservoir on the south side of Dalingshan Forest Park in Dongguan. Extend 50 meters to both sides with the more severely damaged area as the center, and extend 15 meters from the bottom of the mountain to the top of the mountain, and trim the planting belt with a width of 50cm-60cm along the contour line. In the 6m range near the bottom of the mountain, the distance between the planting belts is 2m; within the range of 9m in the direction of the top of the mountain, the distance between the planting belts is 3m. In all ranges, the distance between plants was 2m. The arrangement of tree species is as follows: the three planting belts near the road at the bottom of the mountain are dominated by Macaranga tannica, and the mixed plantings of sycamore, yellow tung and yinxiang (see figure 2 ). In the two growing seasons after the afforestation project, the seedlings in the planting area were ...

Abstract

The invention provides a protection forest belt construction method for preventing and treating a mikania micrantha spreading risk. A macaranga tanarius and X mode is adopted for grown plants for resisting growth of mikania micrantha, X is at least one of heteropanax fragrans, endospermum chinense and cinnamomum burmanni, and macaranga tanarius is planted at the outmost portion. The protection forest belt construction method has the advantages that the mikania micrantha H.B.K is prevented and controlled with an ecological means, the environment is not polluted, and the long-term effectiveness is achieved; the mikania micrantha can be prevented and treated, the vegetation coverage rate of an original area can be further improved, and the effect of ecologically reforming and recovering the risked environment is achieved; manpower supports and financial supports are needed to be invested only in the initial protection forest belt construction period, and investment is basically not needed after a protection forest is established.

Description

technical field [0001] The invention discloses a method for controlling the spreading damage of Mikania micrantha by using a multi-species combination shelterbelt, and belongs to the technical field of harmful plant ecological control. Background technique [0002] Mikania micrantha H. B. K. is a perennial herbaceous vine of the genus Eupatorium in the Asteraceae family. It is native to Central and South America, and is now widely distributed in tropical and subtropical regions of Asia-Pacific and causing serious damage. Mikania micrantha was listed as one of the top ten harmful weeds in the world by the International Union for Conservation of Nature (IUCN) in 2001. In 2003, it was announced by the State Environmental Protection Administration of China and the Chinese Academy of Sciences as an alien invasive species that is extremely harmful to my country. According to statistics, as of 2009, the distribution area of ​​Mikania micrantha in my country has reached 100,000 hm ...
