Abstract

The invention belongs to the technical field of environmental protection and ecological balance and particularly relates to a method for restoring wetland vegetations based on a yellow flag sowing method. According to the method, micropores are fist produced in the surfaces of loofah sponges through enzymolysis, the self-cross-linking reaction produced by dopamine under dissolved oxygen is utilized to make the surfaces of loofah sponges and the micropores attached with a layer of dopamine film, then fermentation is performed by using a substance rich in amino acid, fermentation liquid and the loofah sponges are mixed to increase the hydrophilic group number on surfaces of the loofah sponges, so that the water-retaining property of the loofah sponges is improved, then the osmotic potential of seeds is reduced by using a calcium chloride solution to make water absorption of cells tend to balance, and metabolism and seed germination of the seeds are promoted. In addition, the calcium chloride solution can also remove seeds which cannot germinate through floatation, finally the seeds are coated with the loofah sponges having the water-retaining property for planting, the seeds are prevented from drifting with wind and water, meanwhile the loofah sponges can retain moisture and can provide nutrients for seed germination after degradation and promote seed germination, and the method has the positive significance on the restoration of wetland vegetations.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and ecological balance, and in particular relates to a method for restoring wetland vegetation by sowing yellow calamus. Background technique [0002] Wetlands, together with land and ocean, are called the three major ecosystems in the world, and their ecological service value and service functions are second to none among the three major ecosystems. Wetlands are restored today mainly through engineering, biological measures, and wetland restoration. Most of the wetland restoration works are carried out from four aspects: wetland matrix, hydrological process, water environment, wetland biology and habitat restoration, among which the improvement and management of wetland matrix and hydrological process involve certain physical terrain transformation, soil replacement, hydrological connection and water level change process . Wetland restoration refers to the restoration or recons...
