Embodiment Construction

[0029] The method for the ecological construction of the symbiosis system of the freshwater shellfish of the present invention will be further described in detail by the following examples.

[0030] The implementation of the present invention, site selection is carried out in Bailianjing River Channel, Pudong, Shanghai, and the water area reaches 1200m 2 , the water depth is 2.0m.

[0031] The specific implementation steps are as follows:

[0032] 1. Choose to plant submerged plants in advance, and plant submerged plant communities composed of bitter grass, weed, hydrilla, glabra, and elodea. The combined submerged plant communities account for the entire water body The coverage rate of the bottom surface is 28%, and the coverage rate of each species is different, among which, the coverage rate is 35% for bitter grass, 25% for weed, 20% for Hydrilla verticillum, 15% for glabra, and 5% for Elodea;

[0033] 2. Next, plant emergent plants after 27 days, plant calamus, cattails,...

Abstract

The invention discloses a method for constructing ntaxial system ecology for fishes, grasses and shellfishes in the fresh-water substance, which is characterized by effectively combining the ecological character of water with the ecological and physiological properties of aquatic organisms to build and repair the ecology of the water substance by the synergy of the symbiotic mode of various organisms such as sunken plants, emergent aquatic plants, floating plants, shellfishes, filter fishes, carnivorous fishes, predatory fishes, omnivorous fishes and herbivorous fishes, giving full play to theself-purification capacity of the ecological system of the water substance, controlling pollution to the water substance and protecting the environment of the waters. The method of the constructing ntaxial system ecology for fishes, grasses and shellfishes in fresh-water substance of the invention can be suitably popularized in and applied to waters such as rivers, lakes, pools and streams.

Description

Technical field: [0001] The invention relates to a method for ecological construction of a freshwater body, in particular to a method for ecological construction of a symbiosis system of a fishweed shellfish in a freshwater body. Background technique: [0002] With the development of society and economy, more and more water areas are built. At the same time, due to the unreasonable development and utilization of natural resources by humans, and the pollution of the water environment by industrial and agricultural production, the water body is full of algae, the water quality deteriorates sharply, and even stinks. , has seriously affected the normal development and reproduction of aquatic organisms, destroyed the balance of the aquatic ecosystem, and directly or indirectly threatened the survival of human beings. Therefore, people pay more and more attention to the control and treatment of water body pollution. At present, the pollution control and treatment methods of fresh ...
