[0039] 1 Materials and methods

[0040] 1.1 Experimental materials

[0041] Shrub Willow ( Salix saposhnikovii A. K. Skvortsov ), densely clustered, with a plant height of 1-2.5 meters, collected from the Jiangsu Academy of Forestry Sciences, cut ungerminated fresh wicker about 2m long and 5-8mm in diameter into short branches, and made 50cm×30cm by willow weaving technology The ecological floating bed has a vertical spacing of 5cm and a horizontal spacing of 0.5cm between the willows, which can fix the overlying plants and grow in the water; tie 30cm×3cm×2cm polyethylene foam strips on the bottom of the floating bed to make a wicker floating bed.

[0042] Lolium multiflorum L., also known as Italian ryegrass, is an annual plant of the genus Lolium genus Poaceae; the stem is erect, the plant height is 50-120cm, and it likes warm and humid climates, with a day and night temperature of 27°C / It grows best at 12°C and is widely planted in the south of the Yangtze River Basin in...

Abstract

The invention provides a willow-woven ryegrass floating bed and a manufacturing method thereof and application thereof. The willow-woven ryegrass floating bed comprises a bed body. The bed body is arranged on a floating body. The bed body is woven by willow twigs and planted with Italian ryegrass. The floating body is made of foam. By means of the willow-woven floating bed, a good water pollution purification effect is achieved, the TN removal rate reaches 91.8%, the TP removal rate reaches 98%, and the previous research achievement is exceeded. Shrub willow is adopted to serve as a floating bed frame and a plant base plate, the water purification effect can be enhanced, the ecological environment is improved, virtuous water circulation is formed, meanwhile secondary pollution is avoided, and the landscape of a river course is beautified. The research result provides a theoretical basis for subsequent dynamic experimental researches and practical application.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to an ecological floating bed. Background technique [0002] Ecological floating bed is a kind of functional landscape that aims at polluted water quality and uses ecological engineering principles to reduce the content of nitrogen, phosphorus and COD in the water body, and has both landscaping and ecological purification. It is generally used for pollution control of surface water bodies and ecological restoration. The purification mechanism is to plant plants on the floating bed, use the absorption of nutrients such as nitrogen and phosphorus by plants, and the degradation of pollutants by root-attached microorganisms to achieve the purpose of purifying water. In recent years, the development and application of ecological floating bed technology in my country is just in a period of rapid development. It uses soilless cultivation technology to transplant aquatic, wet and t...
