preparation example Construction

[0025] The present invention also provides a preparation method of the above-mentioned composite base material, which includes the following steps: after mixing each raw material with water, stirring to form a gel group, and setting the shape.

[0026] The amount of water used in the present invention is not particularly limited, as long as the composite substrate can be molded. In a specific embodiment of the present invention, the amount of water used is 25-45 parts by weight. The present invention has no special limitation on the specific way of shaping, and the shaping can be done by mold or by manual shaping. The present invention has no special limitation on the specific shape of the composite substrate, which may be cube, cuboid, spherical, etc. In a specific embodiment of the present invention, the finished substrate has a size of 1-3 cm. After the composite base material of the present invention is made, it can be used alone or put into a matching planting cup for sub...

Embodiment 1

[0030] Take 35kg of lake mud, 8kg of clay, 0.1kg of iron black, 10kg of coconut peat soil, 0.02kg of activated carbon, 0.1kg of denitrification microbial agent, 0.1kg of rooting powder and mix evenly, dissolve 0.1kg of water-absorbing gel with 25kg of water to form a gel Gel, mix the gel group with the above ingredients evenly, and pour it into the mold.

[0031] After drying in the shade, the mold was removed to obtain cube particles with a length of 2 cm.

[0032] Put the cube base material into the corresponding planting cup, select the vigorously growing, 10cm-long Foxtail algae, pass through the sponge, stuff it into the planting cup, and seal the cube base material. Then put it into the laboratory simulation water body where the bottom mud is floating mud, the water body is 0.5m high, the bottom is 1.5m long, and the width is 0.5m.

[0033] After one month's growth, the survival rate of P. spicaculata is as high as 90%, the rooting rate is 80%, and the length reaches 0....

Embodiment 2

[0035] Take 50kg of lake mud, 25kg of clay, 0.2kg of iron black, 15kg of coco peat soil, 0.05kg of activated carbon, 0.35kg of phosphorus-removing microbial agent, and 0.15kg of rooting powder. Gel, mix the gel group with the above ingredients evenly, and pour it into the mold.

[0036] After drying in the shade, the mold was removed to obtain spherical particles with a length of 3 cm.

[0037] Put the spherical base material into the corresponding planting cup, select the vigorously grown, 5cm-long Hydrilla verticillum, pass through the sponge, stuff it into the planting cup, and close the planting cup. Then put it into the simulated water body in the laboratory without sediment, the water height is 0.5m, the bottom length is 1.5m, and the width is 0.5m.

[0038] After a month of growth, the survival rate of Hydra verticillium is as high as 92%, the rooting rate is 87%, and the length reaches 0.5m. The growth is good, the color is bright green, and the plant is strong.

Abstract

The invention provides a submerged plant biomass composite base material as well as a preparation method and application thereof, and belongs to the technical field of water ecological restoration. The submerged plant biomass composite base material provided by the invention is prepared from the following raw materials in parts by weight: 35 to 50 parts of lake mud, 0.1 to 0.6 part of water-absorbing gel, 8 to 30 parts of clay, 0.1 to 2 parts of iron black, 10 to 30 parts of coco coir soil, 0.02 to 5 parts of activated carbon, 0.1 to 5 parts of a microbial agent and 0.1 to 0.5 part of rooting powder. The substrate can be used for planting and putting submerged plants into lakes, can also be used for germination of aquatic plant seeds, provides a carbon source for the submerged plants to adapt to water environment growth at the initial stage by adding different substrate materials, and can promote abundance of microorganisms in local areas of planting water and accelerate formation of plant rhizosphere microbial communities by adding microbial agents. The field planting of the submerged plants in the water body is facilitated. Through the synergistic effect with the planting cup, the problem of submerged plant recovery caused by unfavorable influences such as unstable water substrate and water flow scouring can be solved.

Description

technical field [0001] The invention belongs to the technical field of water ecological restoration, and in particular relates to a submerged plant biomass composite base material and a preparation method and application thereof. Background technique [0002] In water ecological restoration work, restoring submerged vegetation is widely considered to be an effective way to control water eutrophication. Too many practices have shown that in areas where submerged plants grow, the water body is mostly clear; in water bodies lacking submerged vegetation, it is often turbid or algae-growing, the bottom of the water is deserted, and even black or smelly. [0003] With the further advancement of water ecological restoration work, a large number of technical personnel have accumulated rich experience and data. Under the premise of physical control of water quality and nutrition indicators, more and more people pay more and more attention to how to maintain the long-term stability of...
