Problems solved by technology

However, the existing shelterbelts only play the role of isolating Mikania micrantha, and cannot control the re-invasion and harm of Mikania micrantha seeds that germinate and grow into the forest with the wind.
In addition, due to the very complex and subtle interrelationships between different plants, forests in different regions, and different invasive plants, the methods of control and restoration are not repeatable, and the reference is very low.

Embodiment 1

[0038] This example takes Mikania micrantha invaded woodland in Zengcheng District, Guangzhou City as an example to illustrate the present invention in detail.

[0039] 1. Experimental site background

[0040] Guangzhou Zengcheng suffered from the invasion of the exotic plant Mikania micrantha, and the damage was very serious. The inventors conducted an investigation on the invasive plant Mikania micrantha in the forestland of Zengcheng, Guangzhou in 2014, and found that the serious invasion of Mikania mikania mainly included eucalyptus forests, litchi and citrus orchards. , The forest ecosystem was severely damaged by Mikania micrantha.

[0041] 2. Experimental steps

[0042] In 2015, in the survey area, 30 acres were selected to implement ecological control. The steps are as follows:

[0043] S1. Manually remove the invasive alien plant Mikania micrantha and dead trees and shrubs, and retain the native plants (including trees, shrubs and herbs) that survive in the woodland;

[0044] S...

Embodiment 2

[0050] This example takes the transformation process of Mikania micrantha invaded eucalyptus forest in Zengcheng District, Guangzhou City as an example to illustrate the present invention in detail.

[0051] 1. Experimental steps

[0052] In 2015, a 50 acre area was selected to implement the technical ecological control of the present invention in the eucalyptus forest reconstruction land in Zengcheng, Guangzhou, and the steps are as follows:

[0053] S1. After cutting down the eucalyptus, manually remove Mikania micrantha and other invasive plants, as well as dead trees and shrubs, and retain other native trees in the woodland;

[0054] S2. Vegetation reconstruction: After completing step S1, randomly mixed planting tree with arborvitae and Porphyratum at a ratio of 4:1. The saplings of Acer truncatum and Tung tree saplings are 80cm high seedlings, which are planted in a row spacing of 2.5-3m and a plant spacing of 2.5-3m to form two species-spaced planting blocks, which are combined...

Embodiment 3

[0060] 1. Experimental steps

[0061] In step S2 of Example 2, the millennium paulownia and Porphyllum vulgare were randomly mixed and planted in a ratio of 1:4, and the millennium vulgare and the millennium paulownia seedlings were bag seedlings with a height of 80 cm respectively, and the rest of the steps remained unchanged.

Abstract

The invention discloses a method of controlling harms of mikania micrantha by allelopathy of local plants. The method comprises steps: after invasive plants in a forest land are removed, the seedlingsof local plants are planted in a mixed mode, wherein the local plants are heteropanax fragrans, macaranga tanarius or aleurites Montana, the seedlings have heights of 50 to 80 cm, and the mixed planting mode is interplanting. The method of the invention has low requirements for tree seedlings, the cost is low, the survival rate is high, the operation is simple and feasible, and the applicabilityis high; through mixed planting, the invasive alien plant Mikania micrantha can be extremely effectively controlled, recurrence is prevented, the invasion harms of other invasive alien plants can alsobe prevented, prevention and control on mikania micrantha in the whole forest community can be realized, and the effects of comprehensive prevention and control can be realized; and the vegetation restoration efficiency is high, and the method disclosed in the invention can be promoted and applied in a large area and has important and far-reaching significance for sustainable development of forests in South China.

Description

Technical field [0001] The invention belongs to the technical field of forest harmful plant prevention and control. More specifically, it relates to a method for controlling the damage of Mikania micrantha using the allelopathy of a native plant. Background technique [0002] Mikania ( Mikania micrantha ) Is a perennial vine native to Central and South America. It is one of the most harmful invasive plants in the world. It is also one of the first batch of 16 invasive alien species announced by the State Environmental Protection Administration. Mikania micrantha has invaded many areas in southern my country due to its rapid growth, strong reproductive power and strong adaptability, causing serious ecological damage and huge economic losses, and has attracted widespread attention from the society. In order to prevent and control Mikania mikania invasion hazards, research work on Mikania mikania prevention and control has been carried out. The control technologies mainly include p...
