Embodiment 1

[0082] Example 1: Study on the prevention and control of Spartina alterniflora with candelabra and its growth characteristics and C, N, P

[0083] In May 2010, a tidal flat was selected in the Quangang Spartina alterniflora sample plot as an experimental plot. Spartina alterniflora was manually cut off and the tidal flat was plowed before planting candelabra hypocotyls. Set up 20m×20m parallel to the embankment in the high tide area The 5 partitions are respectively recorded as K 1 District, K 2 District, K 3 District, K 4 Zone, G Zone, K 1 、K 2 、K 3 、K 4 Candelabra hypocotyls with a plant spacing of 25cm, 50cm, 75cm and 100cm in turn in the 4 plots, after the hypocotyls are collected, pick the ones that are strong and free from insect diseases and can be directly planted. Area G was also treated by cutting Spartina alterniflora and plowing the bottom mud, but the hypocotyls of candela were not planted, so they were put aside for observation. The other side is the o...

Embodiment 2

[0123] Example 2: Comparison of soil physical and chemical properties between the candela plot and the Spartina alterniflora plot

[0124] The candela plot and the Spartina alterniflora plot are located in the demonstration base of the Spartina alterniflora prevention and control project in Quangang. Plow the soil and then plant the hypocotyls of candela to establish and develop. The remaining covered area of ​​Spartina alterniflora is the plot of Spartina alterniflora.

[0125] Soil samples were collected twice in July 2011 and July 2012, and the soil samples were collected each time in the control area of ​​Spartina alterniflora (high tide area in S area), the control area of ​​mowing (Area G) and 4 areas of candela (K 1-4 Zones, 1, 2, 3, and 4 respectively indicate that the planting distance of candela is 25cm, 50cm, 75cm, and 100cm), and there are 6 plots in total. Each plot is collected at 5 points according to the S-shaped line. At each point, the soil at two depths ...

Embodiment 3

[0152] Reality Embodiment 3: the comparison of benthos in the candela plot and the Spartina alterniflora plot

[0153] The research plot was selected in the demonstration base of Spartina alterniflora prevention and control project in Quangang, Meizhou Bay. The hypocotyls were formed after planting, and until July 2011, few sporadic Spartina alterniflora appeared in the candelian plots. After artificial treatment, no Spartina alterniflora re-grew in the candelian plots. The control plot of Spartina alterniflora is located about 10m to the left of the candela plot, and there are stone piles between the two plots. The natural environment of the demonstration base is the same as above

[0154] Sampling time and method

[0155]In February 2011 and July 2011, 5-8 sampling points were selected in the demonstration base of Spartina alterniflora and Candelabra, and the soil was collected with a 25cm×25cm sampler at a depth of 20cm. Each sampling point Collected twice. After th...

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...
