Method for managing spartina alterniflora

Abstract

The invention provides a method for managing spartina alterniflora. The method comprises the following steps of cutting off the spartina alterniflora; turning over intertidal zones; and planting embryonal axes of kandelia candel. Management on soil, with the depth of 0-20cm, for the spartina alterniflora is replaced by cutting off the spartina alterniflora, turning over the intertidal zones and planting the kandelia candel; the organic matter content and the N (nitrogen) content of the soil are obviously increased; the salinity of the soil is obviously improved by the high-density kandelia candel; pH (potential of hydrogen) of the soil is reduced, and is continuously reduced along with increasing of the density of the kandelia candel; influence on the P (phosphorus) content of the soil is quite low; the organic matter content of the soil with the depth of 20-40cm is increased, and is positively correlated with the density of the kandelia candel; the N content, the P content and the pH of the soil are reduced; and the pH is continuously reduced along with increasing of the density of the kandelia candel. After the kandelia candel is planted for one year, the density and the biomass of large benthonic animals are increased; and the density and the biomass of polychaetes animals, crustacean animals and other animals and the biomass of mollusk are improved. The method can be effectively used for managing the spartina alterniflora.

Description

Technical field [0001] The invention involves the field of ecological environmental protection.Specifically involves a method of govern each other. Background technique [0002] In China, my country has introduced martyrs from the United States in 1979 (Nanjing University Spartina Altermiflora , Native to the North American Atlantic Coast, a perennial grain plant plant that grows in the tide of tide), is used as a beach and embankment. First, it was successful in Jiangsu. In 1980, it was introduced to Fujian.Guangdong, Guangxi, Zhejiang and Shandong.Due to the wide adaptability, strong resistance to reverse resistance, fast reproduction speed, and lack of natural enemies, it quickly breeds and spread throughout the country, causing harm to the near -shore environment, biodiversity, and aquaculture.To the native mangrove area, the coastal mangrove ecosystem declined. Therefore, in 2003, it was included in the list of sixteen foreign invasion species in China in 2003. [0003] In r...

Problems solved by technology

[0006] Although S. apetalum grows rapidly and can effectively control Spartina alterniflora, large-scale artificial pure forests of S. apetalum have been formed along the coast of South China after being planted in large quantities. There is a tendency to degenerate after the number of years; at the same time, alien species of the genus Apetala do not have the tolerance of native tree species in the face of extreme weather conditions, and have the potential to be damaged in large areas
