preparation example Construction

[0055] A preparation method of an aquatic plant growth bed, comprising:

[0056] The plant growth body preparation step: adding the microbial culture and the plant growth compound bacteria to the mixture of sodium alginate and glucoside, and mixing to obtain a compound bacteria gel; Put into 3%wt calcium chloride solution to carry out curing reaction, wash with distilled water to stop the reaction, and obtain plant growth body;

[0057] The composition of compound bacteria gelling liquid is calculated in parts by weight:

[0058]

[0059] Bed preparation steps: mix fly ash, metakaolin, coal gangue and stones with an aqueous solution of sodium hydroxide and sodium silicate to obtain a mixture of raw materials for bed preparation. After the mixture is mixed with plant growth, it is put into a mold Medium solidification and molding to obtain a bed body with plant growth bodies;

[0060] The mass ratio of the raw material mixture and the plant growth body is (3-5): 1; under t...

Abstract

The invention discloses an aquatic plant growth bed and a preparation method thereof. The aquatic plant growth bed comprises a bed body, a plant growth body and a microbe filling body; the plant growth body is arranged in the bed body; the plant growth body is wrapped by roots of aquatic plants; plant growth composite bacteria are arranged in the plant growth body; a gap is formed in the bed body;a gap of the bed body is filled with the microbe filling body; water body purifying microbes are arranged in the microbe filling body; the plant growth body and the microbe filling body are filled with a microbial culture. The preparation method comprises the following steps: preparing the plant growth body; preparing the bed body; executing microbe filling. The aquatic plant growth bed saves thecomplicated steps of firstly pumping water, dredging sediment, planting plants and pumping water back during conventional planting, the plants can be planted on the growth bed first and then put intowater, the putting efficiency is greatly improved, the growth bed has a good fixing effect on microbes, and the water quality can be continuously improved.

Description

technical field [0001] The invention relates to an aquatic plant growth bed and a preparation method thereof, belonging to the technical field of ecological conservation. Background technique [0002] Lake is one of the important freshwater resources for a country's economic and social development. It not only has functions such as climate regulation, water conservancy and flood control, aquaculture, water supply, scenic tourism, etc., but also protects biodiversity and maintains the balance of regional environmental ecosystems. also play an important role. In recent years, due to the rapid economic development, the rapid population growth, the rapid advancement of industrialization, urbanization and agriculture, a large number of nutrients (N, P, etc.) and organic matter have been discharged into the lake, resulting in excessive reproduction of phytoplankton, decreased transparency, and lakes. The water quality deteriorated rapidly, and the eutrophication trend of the lake...
