Problems solved by technology

In recent years, in order to control the invasion of Spartina alterniflora, people have successively adopted methods such as chemical control, physical control and biological control to control Spartina alterniflora, but the effect is very unsatisfactory. , low efficiency, high cost, and difficult to eradicate; chemical methods are likely to cause environmental pollution; biological control methods using natural enemies may bring ecological risks

Embodiment 1

[0019] Embodiment 1 The obvious synergistic effect of diesel oil to high-efficiency flurifop-pylene slick oil

[0020] The test site of present embodiment is Oujiang Estuary tidal flat, establishes 10 processings and a CK respectively to the Spartina alterniflora of candela mangrove plant afforestation land, sprays the stem and leaf of Spartina alterniflora on April 15th of the first year, In June and November, the deadness of Spartina alterniflora was investigated, and the coverage of surviving Spartina alterniflora was calculated on June 28, November 3, and April 3 respectively (the survival coverage area of ​​Spartina alterniflora accounted for the total area of ​​the treatment area. The ratio of the area, unit %), and the 2nd year statistics the growth situation of candelabra in April, calculate the candelabra preservation rate (%), seedling height (cm) and ground diameter (the diameter of the stem near the ground surface, unit cm). 10 processes and a CK are processed acco...

Embodiment 2

[0024] Example 2 The significant effect of pre-cutting Spartina alterniflora in March, and the selection of the high-efficiency flurifop-methyl slick oil dosage

[0025] The test site of present embodiment is Oujiang Estuary tidal flat, establishes 10 processings and a CK respectively to the Spartina alterniflora of candela mangrove plant afforestation land, sprays the stem and leaf of Spartina alterniflora on April 15th of the first year, In June and November, the deadness of Spartina alterniflora was investigated, and the coverage of surviving Spartina alterniflora was calculated on June 28, November 3, and April 3 respectively (the survival coverage area of ​​Spartina alterniflora accounted for the total area of ​​the treatment area. The ratio of area, unit %), and the 2nd year counts the growth situation of candela in April, calculates candela preservation rate (%), seedling height (cm) and ground diameter (the diameter of seedling stem near the ground surface, unit cm), wh...

Embodiment 3

[0030] The consumption selection of embodiment 3 diesel oil

[0031] The test site of this embodiment is the tidal flat of the Oujiang Estuary. Three treatments and one CK are respectively set up for the Spartina alterniflora in the candela mangrove plantation land. Apply the stems and leaves of Spartina alterniflora, investigate the dead situation of Spartina alterniflora in June and November, and calculate the coverage of surviving Spartina alterniflora on June 28, November 3, and April 3 ( Spartina surviving coverage area accounted for the ratio of the total area of ​​the treatment area, unit %), and the statistics of the growth of candela in April of the second year, calculating the preservation rate of candela (%), seedling height (cm) and ground diameter (the stem of the seedling is close to the ground surface The diameter at the place, in cm). 3 processes and a CK are processed according to the situation described in table 3, and the active ingredient content of high-e...

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.

Description

technical field [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. I...
