Embodiment 1

[0040] The submerged plants were selected from the typical submerged plants in Yunnan, Erythrina spicata, Trichosanthes spicatus, and the invasive species of Trichosanthes viridis, which are widely distributed in Yunnan.

[0041] 1) Plant treatment: Rinse the submerged plants collected in the field with tap water, and cut out the vegetative propagules of the same specification after rinsing. ), weight 0.5g; two kinds of foxtail algae all choose top length 7cm and weight 0.5g, each plant vegetative propagule clipping is planted in the pre-cultivation pot (67cm * 45cm * 55cm), adds 20cm high tap water, Pre-cultivate for two weeks to acclimatize indoors.

[0042] 2) Device Settings ( figure 1 ): The device used is an indoor artificially constructed pool, which is mainly composed of an aeration pump, an aeration tank, a micro-control switch, a water inlet, a transparent baffle, and a water outlet. The size of the pool is 100cm×60cm×50cm.

[0043] 3) Plant planting: plant the pr...

Abstract

The invention provides a method for evaluating competitive dominance of submerged plants in different hydrodynamic areas and application, and relates to the technical field of ecological restoration of submerged plants. According to the method, according to hydrodynamic characteristics of different areas of a water body, an indoor cosmic test is set to simulate different hydrodynamic conditions, indigenous species in a target water area are selected for co-planting culture, and changes of competitive dominance degrees of different species under different hydrodynamic conditions are evaluated; powerful theoretical support and practical basis are provided for constructing submerged plant communities for field restoration. According to the method, a competitive system is constructed, submerged plant species with large competitive advantages under different water exchange conditions are selected, and reference is provided for submerged plant restoration in the field; the method is simple to operate and low in cost.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration of submerged plants, and in particular relates to a method and application for evaluating the competitive dominance of submerged plants in different hydrodynamic zones. Background technique [0002] As an important component of lakes, submerged plants play an important role in maintaining their ecological functions. Submerged plants are not only primary producers, providing abundant food for aquatic animals, but also providing them with habitats and breeding places, which is conducive to maintaining biodiversity and maintaining the stability of the entire water ecosystem. Therefore, in shallow lakes, areas where submerged plants are densely distributed have better water quality and lower nutrient concentrations. Since submerged plants are completely aquatic, water environmental factors have a significant impact on the community structure of submerged plants. [0003] In the natura...
