Embodiment 1

[0041] Seagrass bottom shop planting method, comprises the steps:

[0042] 1) Collect seaweed seeds:

[0043] Collect seaweed seeds in the seagrass field in the seaweed fruiting period in advance, and reserve them;

[0044] 2) Seaweed seed pretreatment:

[0045] Select mature and plump seeds, first soak them in 60% alcohol solution for 30 seconds, rinse them with sterile seawater for 3 times, and set aside;

[0046] 3) Make the bottom layer of seeds:

[0047] Fold the cotton fiber mesh cloth in half and sew it to make the bottom layer network frame 1;

[0048] Select ceramsite as the base material, mix the base material and the pretreated seeds evenly to obtain the filler 3, fill the filler 3 in the bottom layer network frame 1, and then wrap the bottom layer network frame 1 with jute thread Sew the seam to obtain the bottom layer of seeds;

[0049] 2,000 seeds per square meter of seed bottom layer;

[0050] 4) Conveying and delivery of the bottom layer:

[0051] Put th...

Embodiment 2

[0053] Seagrass bottom shop planting method, comprises the steps:

[0054] 1) Collect seaweed seeds:

[0055] Cut off the reproductive branches with mature seeds in the seagrass field in the seaweed fruiting period in advance, and transport them to the pool of the nursery room for temporary cultivation in an incubator treated with ice. Change the water once a day. After the seeds fall off naturally, put The scattered seeds are collected in another pond for subsequent use;

[0056] 2) Seaweed seed pretreatment:

[0057] Select the seeds whose epidermis is transparent and can see the small germ buds inside the seeds as mature and plump seeds through microscopic observation, soak them in 90% alcohol solution for 30 seconds, wash them with sterile sea water for 3 times, and set them aside;

[0058] 3) Make the bottom layer of seeds:

[0059] Fold the jute mesh cloth in half and sew it according to the following steps to make the bottom layer network frame 1: a) fold the jute me...

Embodiment 3

[0065] In the step of the seaweed bottom shop planting method, except that the following content is different from Example 2, all the other contents are the same: in step 2), the alcohol solution is an alcohol solution with a volume fraction of 75%; in step 3), the substrate is pottery The mixture of granules, sea sand and the bottom mud of the former seagrass field, wherein the weight and number ratio of ceramsite, sea sand and the bottom mud of the former sea grass field is 3:1:1; in step 3), the plant fiber mesh used is No. 40 jute mesh cloth, the used plant fiber suture is jute thread; in step 3), contain 2500 seeds in the bottom layer of every square meter of seeds.

Abstract

The invention discloses a sea grass bottom laying planting method, and belongs to the field of ecologic environment restoring. The method comprises the first step of sea grass seed collecting, the second step of sea grass seed preprocessing, the third step of seed bottom laying layer manufacturing and the fourth step of bottom laying layer conveying and throwing. The sea grass bottom laying planting method is simple, practicable, simple in technology, low in requirement for operation conditions, capable of saving labor, free of underwater operation, capable of reducing labor and material resource consumption, free of pollution and capable of effectively guaranteeing the restoring of the seabed ecological environment.

Description

technical field [0001] The invention belongs to the field of ecological environment restoration, and in particular relates to a method for planting seaweed bottom paving. technical background [0002] Seagrass beds play an important ecological role in promoting silt consolidation, improving nearshore water quality, and maintaining global carbon cycle balance. However, this ecosystem is one of the most fragile on Earth, with 18% of the globally recorded seagrass covering an area of ​​approximately 33,000 km2 lost due to direct or indirect human impact in the past two decades. loss, and the rate of global seagrass decline is accelerating! The accelerated degradation of global seagrass has also led to the intensification of the deterioration of the coastal ecological environment. Therefore, seagrass bed restoration is of great significance to protect existing seagrass resources, improve water environment, increase marine biodiversity, and increase fishermen's income. However...
