Embodiment 1

[0033] (1) Production of breeding blanket

[0034] Such as figure 1 The breeding blanket shown is composed of carrier layer, substrate layer and adhesion layer from bottom to top. The carrier layer at the bottom is composed of plant fibers with a thickness of about 2 cm. The substrate layer in the middle is composed of humus, silt and The slow-release curing agent is mixed and configured to form a matrix with a thickness of about 3 cm. The matrix is ​​selected from any of the following formulas: humus 40%, silt 30%, slow-release curing agent 30%; humus 50%, Silt accounted for 25%, release curing agent accounted for 25%; humus accounted for 35%, sludge accounted for 40%, slow release curing agent accounted for 25%; humus accounted for 50%, sludge accounted for 40%, slow release curing agent accounted for 10% %. Slow-release solidifying agent selects any one in polyethylene, urea formaldehyde, urea isobutyraldehyde, urea hexanal, or oxamide, and the attachment layer positioned...

Embodiment example 1

[0043] Implementation case one (adjustable water level area):

[0044] The project implementation site is located in Xinchengtang, Jiaxing City, Zhejiang Province. The length of the project river section is 1.0km, and the average width is 10m. Due to the small width of the river channel where the project is located, the bottom mud is seriously silted up and the water passing capacity is poor. After the dredging of the river, the construction cofferdams at both ends of the river will be retained, and the restoration of submerged plants will be carried out. Initially, the construction cofferdam is used to control the water depth in the river section of the project to 20cm. From March 20 to 22, 2010, the breeding blanket with an average seedling height of about 10cm cultivated from the seedling base was transported to the project area by car and laid artificially on the bottom of the river. A total of 2500m of breeding blankets were laid in the project 2 , among which three ki...

[0047] Implementation case 2 (open waters with uncontrollable water level):

[0048] The project implementation site is located at the mouth of a river along the Gonghu Lake of Taihu Lake in Suzhou City, Jiangsu Province. The ecological restoration area covers an area of ​​20 mu, and the average water depth in the project area is 1.50m. The transparency of the water body affected by wind and wave disturbance is low, only 30-40cm, the current situation The ecological environment is poor, and direct transplantation of submerged plants cannot survive. Since the project area is part of the open waters of Taihu Lake and does not have the conditions for water level control, it is necessary to adopt appropriate engineering and technical measures to regulate the environment of the ecological restoration area based on the analysis of the environmental characteristics of the ecological restoration area. In February 2009, the project first set up two soft enclosures around the project wa...

Abstract

The invention relates to a submerged plant breeding blanket and application thereof. The submerged plant breeding blanket disclosed by the invention is respectively composed of a carrier layer, a matrix layer and an adhesive layer from bottom to top, wherein the carrier layer is composed of palm and bamboo plant fiber; the matrix layer is composed of a growing matrix suitable for submerged plants to grow; and the adhesive layer is composed of a plant fiber net. The invention further provides a submerged vegetation transplantation technology which is characterized in that after being subjected to seedling culture, submerged plant seedling breeding embryoid bodies prepared by virtue of the breeding blanket are transplanted to the water bottom of an ecological restoration area for planting and restoring submerged vegetation of the ecological restoration area. Compared with the traditional submerged plant transplantation technology method, the submerged vegetation transplantation technology disclosed by the invention has the advantages of low transplantation cost, high speed, high survival rate, convenient technology, strong technical maneuverability, high community forming speed after transplantation, high breeding speed, good community stability and the like, and can be used for realizing the quick transplantation and the community construction and configuration of the submerged plants.

Description

technical field [0001] The invention belongs to the technical field of ecological environment engineering, and in particular relates to a submerged plant breeding blanket suitable for submerged vegetation restoration and an application thereof. Background technique [0002] Affected by the rapid economic and social development, the water pollution of our rivers and lakes is getting worse day by day, the eutrophication of lakes is serious, and the degradation of aquatic ecosystems is serious. With the deepening of water pollution and treatment research, the current laboratory-scale research generally believes that compared with physical and chemical technology, it is better to restore the aquatic vegetation community in the water body to control water pollution and lake eutrophication through ecological restoration and reconstruction methods. A relatively ideal pollution control technology approach. [0003] Among the ecological groups of aquatic plants, submerged plants hav...
