Method for inhibiting Mikania micrantha in non-forest land with little or no tillage and no artificial irrigation by using tall grasses

Abstract

The invention discloses a method for inhibiting mikania micrantha by means of high-stalk grass in minimal-tillage or no-tillage non-forestry land free of artificial irrigation. The method comprises the steps of grass selection, plantation, bag seedling transplantation, seedling management, later-period management, and next-year and long-term management. High-stalk grass for feeding use is utilized; by controlling the growth vigor of high-stalk grass and mikania micrantha, mikania micrantha is prevented from climbing to the top end of certain high-stalk grass to cover the high-stalk grass, in this way, mikania micrantha is inferior in competition for light, and then growth of mikania micrantha is inhibited.

Description

technical field

[0001] The invention relates to the technical field of prevention and control of invasive plants, in particular to a method for inhibiting Mikania micrantha in non-forest land with little or no tillage and unmanned irrigation by using tall grasses. Background technique

[0002] Mikania micrantha is native to Central and South America, mainly distributed in Mexico, Brazil, Ecuador, Peru, Colombia, Argentina, and Bolivia. It has invaded Southeast Asia, the Indian subcontinent, the Pacific Islands, Australia, Mauritius and other places. In 2009, Mikania micrantha was found in the United States. my country first collected Mikania micrantha specimens in Hong Kong in 1884; thereafter, specimens were collected in Yunnan and Shenzhen Yinhu in 1983 and 1984 respectively. At present, Mikania micrantha has spread widely in southern China, Guangdong, Yunnan, Taiwan , Hong Kong, Guangxi, Hainan, and Macau are all distributed; among them, Guangdong, Yunnan, and Taiwan are ...
