Culture medium and culture method for planting reeds on artificial floating islands

Abstract

The invention discloses a culture medium for planting reeds by using an artificial floating island. The culture medium comprises a polyethylene glycol mixed liquid matrix and a simulated soil solid matrix, wherein the simulated soil solid matrix is prepared from expanded vermiculite and saw powder; the polyethylene glycol mixed liquid matrix is prepared from polyethylene glycol, a NaCl aqueous solution and biological bacterial fertilizer. The invention provides a preparation method of the culture medium for planting the reeds by using the artificial floating island and also provides a culturemethod for planting the reeds by using the artificial floating island. The reeds are planted by using the artificial floating island, an L-shaped floating tube device fixed on center struts of the artificial floating island is used as a carrier for propagation and growth of reed seeds, and the germination process of seeds is not affected by the depth of a water body on the water; in addition, plants can be fixed by meeting different demands. The culture medium for planting the reeds, disclosed by the invention, has the advantages that the germination rate of the reed seeds is increased to 10 percent or above, so that the purification capacity of the water body is improved more effectively, and the artificial floating island has important significance in a control technology of eutrophication pollution of a river water body; in addition, the culture medium has certain application value.

Description

Technical field: [0001] The invention relates to a method for planting reeds, in particular to a culture medium and a cultivation method for planting reeds using artificial floating islands. Background technique: [0002] Phragmites reed is a plant of the genus Phragmites in the Poaceae family, which is widely distributed all over the world. It is a common aquatic plant. Like other plants in the Poaceae family, Phragmites reed has a well-developed fibrous root system, and the stems are divided into two types: erect stems and rhizomes. The rhizome is multi-noded and can produce multiple tillers. The erect stem obviously has two parts: nodes and internodes (stems are often called culms in grasses; stems in bamboos are called poles to show that they are similar to grasses. difference); the internode is hollow, usually cylindrical, or slightly flattened, the pith is attached to the inner wall of the cavity, but there are also those that fill the cavity and make the internode sol...

Problems solved by technology

However, due to the influence of the depth of the water body, living reed cuttings are generally suitable for water depths below 0.5m, and cannot achieve the expected goal.
