Embodiment Construction

[0040] Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0041] The present invention takes typha, a typical aquatic wetland emergent plant, as an example, and provides a method for inducing manganese film on the surface of cattail root. By constructing a manganese film induction device, ethylene precursor ACC and phytohormone gibberella are applied to 8 roots of cattail. GA, which effectively increases the number of manganese films on the root surface; and in the same device, the sy...

Abstract

The invention belongs to the technical field of water ecological restoration, and particularly discloses a device and method for inducing the root surface of emergent aquatic plants to be coated withmanganese films, wherein the method comprises the steps: S1, tissue culture; S2, preparation of a manganese film induction liquid; S3, construction of an induction device; and S4, efficient inductionof the manganese films. The efficient manganese film induction device is scientifically constructed, the adjusting effect of ethylene and gibberellin on formation of root surface manganese films is fully utilized, and the number of the root surface manganese films is increased; the ecological environmental benefits of wetland emergent aquatic plants are improved by utilizing the synergistic effectof the plant root surface manganese films, inorganic mineral porous fibers, other matrix filler surface manganese films and a functional biological film. The device and method can be widely applied to treatment of various types of sewage, have good performance on ammonia nitrogen degradation, phosphate absorption and heavy metal immobilization, and has the characteristics of economy and practicability.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation and water ecological restoration, and more specifically relates to a device and method for inducing emergent plant roots to be coated with manganese film, and also relates to the application of the method in water ecological restoration. Background technique [0002] Aquatic plants have been widely used in the sewage treatment process in natural and artificial wetlands, especially the emergent plants in artificial wetlands have developed root systems and strong oxygen secretion capacity, which can absorb nutrients in the water body and reduce the water body. Eutrophication degree, inhibition of algae growth. Many microorganisms can oxidize soluble divalent manganese into insoluble manganese oxides, and in the natural state, the rate of microbial oxidation to high-valent manganese can reach 105 times that of non-biological processes. Microbes that can oxidize Mn(II) can not only oxidize ...
