Problems solved by technology

Physical methods mainly use manual extraction, but manual extraction is not suitable for dealing with large areas of Spartina alterniflora, and the effect is not very satisfactory; chemical agents are used, which may have toxic side effects; biological methods are mainly controlled by natural enemies, and are afraid of introducing New species cause new biological invasions

Embodiment 1

[0016] The present embodiment one discloses a kind of coastal wetland Spartina alterniflora biological-physical prevention and control method, wherein:

[0017] (1), pretreatment: After determining the sample plot, manually harvest Spartina alterniflora on the sample plot, and smash and plow the roots of Spartina alterniflora;

[0018] (2), spread plastic film: spread one deck plastic film on the sample ground after pretreatment; For preventing sea breeze and tidal water from washing away plastic film, we suppress the four sides of plastic film with silt;

[0019] (3), determine planting specification: the selected mangrove plant is candela, and described candela is hypocotyl.

[0020] The planting specification depends on the size of the seedlings. There are no certain regulations. The seedlings of candela are small, so they should be planted densely to ensure the number of survival; but not too dense, so as not to affect the normal growth of candela.

[0021] In this embodi...

Embodiment 2

[0029] (3), determine planting specification: the selected mangrove plant is candela, and described candela is hypocotyl.

[0030] In this embodiment, hypocotyls are used for the candeli, so the planting specifications are row spacing×plant spacing: 100 cm×100 cm.

[0031] (4), planting:

[0032] Plant 100 centimeters × 100 centimeters of candela on the sample plot, make a hole every 100 centimeters on the plastic film, and plant the candela in the hole.

[0033] The other steps are the same as in the first embodiment, specifically refer to the steps described in the first embodiment.

Embodiment 3

[0035] The present embodiment three discloses a kind of coastal wetland Spartina alterniflora biological-physical prevention and control method, interplanting candela and Sangria apetalum on the plot, wherein:

[0036] (3), determine planting specification: the mangrove plant of selection is candela and Sangria apetalum, and described candela is hypocotyl, and its planting specification is row spacing * plant spacing respectively: the planting specification of 50 centimeters * 50 centimeters. The Sangria apetalum is an annual seedling, and its planting specifications are row spacing×plant spacing: 2 meters×2 meters.

[0037] (4), planting: After determining the planting specifications, punch holes in the corresponding positions on the plastic film according to the planting specifications, and then plant the mangrove plants on the holes.

[0038] Plant the candela with row spacing × plant spacing of 50 cm × 50 centimeters on the sample plot, punch a hole every 50 centimeters on...

Abstract

The invention discloses a method for physically preventing and controlling a coastal wetland by using spartina alterniflora. The method comprises the following steps of: (1) pretreatment: selecting a sample plot with spartina alterniflora, artificially harvesting all the spartina alterniflora, and mashing and turning over the roots of the spartina alterniflora; (2) spreading a plastic film: spreading the plastic film on the pretreated sample plot; (3) planting: after the planting specifications are determined, drilling holes according to the corresponding positions of plant spacing on the plastic film, and planting mangrove plants in the holes; and (4) reclaiming the plastic film: reclaiming the plastic film when the roots of the spartina alterniflora are totally dead and the mangrove plants are grown stably.

Description

technical field [0001] The invention relates to a biological-physical prevention and control method for Spartina alterniflora in coastal wetlands, and belongs to the technical field of ecological engineering. Background technique [0002] Spartina alterniflora belongs to Poaceae and Spartina. It is a perennial herb. It originated from the Atlantic coast of America and the Gulf of Mexico, and is suitable for living in the intertidal zone. Because the straw of Spartina alterniflora is dense and thick, and its underground rhizomes are well developed, it can promote the rapid sedimentation and deposition of sediment. Therefore, many countries introduced it successively in the early 20th century in order to protect beaches and embankments, and promote siltation and land formation. Although Spartina alterniflora has important ecological functions in coastal ecosystems, its strong fecundity in tidal flat wetland habitats threatens indigenous species in coastal wetlands around the w...
