Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] 1. On-site investigation of hydrological conditions, lake bottom topography, sediment matrix, wind and waves, shipping, etc. in the deep water area of ​​the lake, paying special attention to factors such as wind force and water flow velocity, and determining the placement, quantity and configuration of emergent plant fixtures. The construction plan mainly includes expected goals, construction period, engineering materials, engineering organization, engineering acceptance and so on.

[0027] 2. Buoyancy barrel

[0028]Buoyancy cask (14) selects the Chinese fir (or willow) plank that is resistant to water erosion, is hooped by upper and lower two iron hoops and hoops and becomes the flat bucket-shaped buoyancy cask (14) that barrel height 60-70cm, upper and lower diameters are respectively 100cm, flat The barrel-shaped structure can ensure that th...

Abstract

The invention discloses a device for growing a big emerging plant on the near water surface of a deep water area of a lake. The device comprises a buoyancy wooden bucket, a pulling rope, an adjusting article and a fixing article, wherein the inside of the buoyancy wooden bucket is divided into an up-and-down two layer structure by a separating board, the lower layer is a buoyancy foam layer filled with foam plastics, and the upper layer is a mounting medium layer filled with porous stones; the lower part of the buoyancy wooden bucket is provided with a connecting piece; the pulling rope passes through the connecting piece and is movably connected with the buoyancy wooden bucket; and one end of the pulling rope is connected with the fixing article, while the other end is connected with the adjusting article. The device makes that the big emerging plant is grown in the deep water area of the lake possible, and better improves the structure and function of an ecological system of the lake. The device has the characteristics of strong operability, low construction cost, practicality, easy popularization and good application prospect, and can be used for ecological restoration of plants in the deep water area of the lake.

Description

technical field [0001] The invention belongs to the technical field of resources and environment engineering, and in particular relates to a device for planting tall emergent plants near the water surface in a deep water area of ​​a lake. Background technique [0002] Emergent plants are an important component of lake ecosystems. It is not only a primary producer with a large biomass, but also provides food, habitat and breeding grounds for aquatic animals, and releases a large amount of oxygen into the water through photosynthesis, which is conducive to maintaining more dissolved oxygen in the water and promoting the reduction of organic pollutants. Oxidative decomposition of non-toxic inorganic substances, reducing the chemical oxygen demand (COD) of water. In addition, emergent plants also absorb heavy metals in water. Therefore, emergent plants help to purify the water quality of lakes, improve the ecological environment of water bodies, maintain biodiversity, maintain...
