Method of using phyla to perform replacement control on mikania micrantha

Abstract

The invention relates to a method of using phyla to perform replacement control on mikania micrantha. The method comprises the following steps of planting phyla in an area planted with mikania micrantha, and controlling the ratio of planting density of phyla and mikania micrantha to be (1 to 3):1. The method has the advantages that the generation density of mikania micrantha is effectively reduced, and the growth and propagation are inhibited; the perennial plant of phyla can perform sustained control on mikania micrantha; the method is simple, is easy to implement, and is suitable for being popularized.

Description

technical field [0001] The invention relates to a method for substituting control of Mikania micrantha by using vines, and belongs to the technical field of ecological control. Background technique [0002] Mikania micrantha H.B.K., native to Central and South America, is a perennial herbaceous vine belonging to the genus Mikania of the family Asteraceae. It was first discovered in Hong Kong in 1919. It was introduced to the coast of Guangdong in the late 1980s and early 1990s, and gradually spread. The areas that have spread now include Guangdong, Guangxi, Fujian, Hainan, Yunnan, Macao, and Taiwan. Mikania micrantha can cover the canopy of the attached plants in a short period of time, affecting plant photosynthesis and normal growth and development, causing plant death, changing species types, affecting biodiversity, leading to the degradation of the original community structure or ecosystem, and ultimately causing farmers, Forestry production and ecological environment c...

Problems solved by technology

[0003] At present, there are mainly the following methods for the prevention and control of Mikania micrantha: 1) chemical control, which is controlled by spraying chemical herbicides. Herbicides are harmful to the environment

2) Manual control, mainly cleaning up the roots, stems and leaves of Mikania micrantha, and then burning or other treatment. Manual eradication will inevitably cause some rhizomes to be not cleaned up. As long as there are two residual rhizomes, they can quickly take root and germinate and continue to grow through rainwater, which is not only a waste of time. , and even aggravate the harm

[0004] Regarding the alternative control of Mikania micrantha, there have been many reports in China. Chinese patent application 201210533086 discloses "a method of using alternative control combined with herbicide application to prevent and control Mikania micrantha". Because sweet potato is an annual crop, it is impossible to control Mikania micrantha for many years, and it has strict requirements on the soil. Most of the suitable planting areas are agricultural land, and it is not suitable for the control of Mikania micrantha in habitats such as mountains; The method of growing new individuals” uses the Mikania micrantha to replace and control Mikania micrantha. Although the maple can control Mikania to a certain extent, the maple belongs to landscape garden plants, and the cost investment is relatively large, so it is difficult to promote and apply it on a large scale.

Chinese patent application 201410343674.1 discloses "a method of using sweet bamboo to control Mikania micrantha as an alternative to controlling Mikania micrantha". The selection of sweet bamboo to replace and control Mikania micrantha has achieved good results in certain habitats, but it is not suitable for planting in habitats such as farmland and orchards; Chinese patent application 201410434658.3 discloses "a method of controlling Mikania micrantha by using Chinese fir". The selection of Chinese fir instead of controlling Mikania micrantha has achieved good results in certain habitats. The Chinese fir needs to be tended for 3 to 4 years, and this method is not suitable for farmland, orchards, etc. Habitat promotion and application
