Embodiment 1

[0021] A control experiment of Spartina alterniflora was carried out by using the method of the present invention in a certain sea area in Shandong.

[0022] Production of PVC board: The length and width are 2m and 1m respectively, the material is opaque board, the thickness is 4mm, and two round holes with a diameter of 1cm are drilled in each of the four corners.

[0023] Other materials used are as follows: ① 50cm U-shaped steel nail (diameter 1cm); ② Sickle.

[0024] The control test process of Spartina alterniflora is as follows: In late April 2017, a 16m×2m area was selected in the test area to manually mow with a sickle close to the surface to remove withered Spartina alterniflora residues. After removing Spartina alterniflora, the For the removed area, fix the opaque PVC board close to the ground surface, put two adjacent boards close together and fix the link across the board with U-shaped steel nails. That is to say, the two legs of the U-shaped steel nails pass thr...

Abstract

The invention relates to a control method of advanced invasive plants in the ecological remediation field of seaweed beds in intertidal zones, and specifically relates to a control method of invasiveplants, namely Spartina alterniflora Loisel in the intertidal zones. A control device of the Spartina alterniflora Loisel is provided with PVC boards and U-shaped steel nails for fixation. After withered Spartina alterniflora Loisel residue in a region is manually removed in an early growth stage (from March to April) of the Spartina alterniflora Loisel in a temperate-zone sea area, a layer of thePVC boards is uniformly and flatly laid close to the surface of earth, and two adjacent PVC boards are fixedly linked together through the U-shaped steel nails. The PVC boards are lightproof and arecapable of effectively preventing growth and propagation of the Spartina alterniflora Loisel. By utilizing the control method, the invasive plants can be effectively controlled; by combining with thesimple, convenient and effective control device of the Spartina alterniflora Loisel, the seaweed beds in the intertidal zones can be conveniently and rapidly remediated or reconstructed; and meanwhile, the PVC boards are capable of durably resisting stormy waves for two or more years and can be repeatedly used after recycling, so that the cost can be saved, the control method is economic and environment-friendly, and sea areas are not polluted.

Description

technical field [0001] The invention relates to the field of ecological restoration and reconstruction of seagrass beds, in particular to a method for controlling the population quantity of intertidal invasive plants (Spartina alterniflora). Background technique [0002] Spartina alterniflora Loisel. belongs to the genus Spartina Schreb. of the Gramineae family. It is a perennial herb with a well-developed root system. It is often densely distributed in the soil layer 30cm deep underground, sometimes as deep as 50-100cm. The stems are tough and erect, up to 1-3m high and more than 1cm in diameter. It has strong stress resistance, can tolerate harsh soil conditions, and is more tolerant to salt stress than other salt marsh plants. It has a strong ability to reproduce and spread in tidal wetlands. It is the most invasive plant in the world. One of the sex species. In the 1970s, Spartina alterniflora was introduced into China, and its distribution area has grown rapidly in th...
