Method for removing spartina alterniflora from beach forestation land of kandelia candel mangrove forest

Abstract

The invention provides a method for removing spartina alterniflora from beach forestation land of a kandelia candel mangrove forest. The method is practical, effective, lower in using amount and moreenvironment-friendly. According to the method, the spartina alterniflora on the forestation land needs to be cut off in March, and when new stems of the spartina alterniflora are drawn out to 30 cm inmid-to-late April, a mixture of haloxyfop-r-methyl and diesel oil is sprayed to stems and leaves of the spartina alterniflora, so that the spartina alterniflora can be thoroughly removed at a time, the effect is achieved instantly, and large-scale reconstruction of the kandelia candel mangrove forest in the coastal mud flat of Zhejiang is achieved.

[0001] The invention belongs to the technical field of ecological environment protection, and in particular relates to a method for clearing Spartina alterniflora from a candela mangrove beach afforestation site. Background technique

[0002] Spartina altermiflora (Spartina altermiflora) is native to the Atlantic coast of North America, and it is a perennial grass growing on the tidal flats of the intertidal zone. In 1979, Nanjing University introduced it from the United States (used as a plant for beach protection and dike protection). It was first successfully planted in Jiangsu, and then introduced into Fujian in 1980. In 1982, it was expanded to Jiangsu, Guangdong, Guangxi, Zhejiang and Shandong. Due to its wide adaptability, strong stress resistance, fast reproduction speed, and lack of natural enemies, it quickly spread across the coastal areas of the country, causing serious harm to the near-shore environment, biodiversity, and aquaculture industry.
