Embodiment 1

[0044] An eco-environmental protection type submerged plant growth promoter, which is made of the following raw materials in mass fraction:

[0045] Raw material %

[0046] Modified Medical Stone 85%

[0047] Magnesium peroxide 15%.

[0048] A kind of preparation method of eco-environmental protection type submerged plant growth promoter, its steps are:

[0049] 1) Soak the medical stone in dilute hydrochloric acid with a mass fraction of 1 or 2 or 3 or 4 or 5% for 1 or 2 hours, wash it with water until neutral, and place it in a muffle furnace at 200°C or 250°C or 300°C °C or 320 °C or 350 °C or 400 °C for 1 or 2 hours to prepare modified medical stone for use;

[0050] 2) Composing the modified medical stone and magnesium peroxide according to the above-mentioned mass fraction, mixing the modified medical stone and magnesium peroxide evenly, and preparing a submerged plant growth promoter;

[0051] The prepared eco-environmental protection submerged plant growth promoter...

Embodiment 2－5

[0053] A kind of eco-environmental protection type submerged plant growth promoter, it is made of the raw material of following mass fraction:

[0054]

[0055] Its preparation method is identical with embodiment 1.

[0056] According to the above-mentioned specific examples of 2-5, it is found that the ecologically-friendly submerged plant growth promoter prepared by the above ratio can significantly increase the dissolved oxygen at the bottom of the lake or river, and the organic matter content of the surface sediment can be reduced by more than 40%. It plays the role of increasing oxygen, improving the living environment of the river bottom and promoting the growth of aquatic plants.

Abstract

The invention discloses an ecological and environment-friendly submerged plant growth promoter as well as a preparation method and an application. The promoter comprises modified medical stone and magnesium peroxide in a certain ratio. The method comprises the steps as follows: 1) clay mineral medical stone is subjected to simple pretreatment modification; 2) the modified medical stone and magnesium peroxide are uniformly mixed in a certain ratio, and the submerged plant growth promoter is prepared. The invention also relates to the application of the ecological and environment-friendly submerged plant growth promoter to water surfaces of lakes or slow flow rivers. The submerged plant growth promoter is environmentally friendly, reasonable in formula, convenient to use and low in cost. Thesubmerged plant growth promoter is ecological and environmentally friendly, can significantly improve the growth rate and quality of submerged plants and effectively solve the problem that submergedplants cannot survive and grow in special habitats and is beneficial to recovery of the ecological environment of water areas, the survival rate of submerged plants reaches 95% or above, and the rootlength, plant height and biomass of the submerged plants are increased by 150%, 80% and 200% respectively or above. Meanwhile, water in remediation areas is improved remarkably, and the water transparency can be improved by 15 cm or above.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration of lakes and rivers, and more specifically relates to a submerged plant growth promoter, and also relates to a preparation method of the submerged plant growth promoter, and also relates to a use of the submerged plant growth promoter , can be applied to restoration projects of eutrophic lakes and rivers. Background technique [0002] The planting and restoration technology of submerged plants is the key technology of ecological restoration projects, and the use of aquatic macrophytes to restore water and sediment pollution is one of the effective ways to control, regulate and inhibit water eutrophication. Submerged plants have huge biomass and exchange a lot of material and energy with the environment, forming a very large environmental capacity and strong self-purification ability. The whole growth process of submerged plants lives in the water, and the roots, stems, and leaves c...
