Abstract

The present invention discloses a method for rapid colonization of rigid underwater aquatic plants. The method comprises a bionic tank body, a composite culture medium and pre-cultured aquatic plants.The method is as follows: uniformly mixing seeds of the pre-cultured aquatic plants and the composite culture medium; filling the mixture in the bionic tank body after the uniform mixing, then placing the bionic tank body in an incubator, adding water for submerge for pre-culture with submersion not exceeding 10 cm; and after 2-3 weeks of the pre-culture and seedlings of the pre-cultured aquaticplants emerge from a tank mouth for 3-5 cm, draining water in an incubation box body, and transferring the bionic tank to a ship and driving the ship to a rigid base water area to be repaired. Beneficial effects are as follows: the method has high-efficiency bottom attachment, rapid colonization of the aquatic plants, simple and rapid implementation, low operating cost, and convenient large-scalepromotion, greatly improves efficiency of improvement of rigid underwater substrate habitat and rapid establishment of the aquatic plants, and is very suitable for reconstruction of the aquatic plants, landscape optimization and rapid and efficient restoration of aquatic ecosystems in rigid underwater, fine gravel riverways and highly polluted sediment water bodies..

Description

technical field [0001] The invention belongs to the technical field of aquatic ecological restoration, in particular to a method for rapid colonization of aquatic plants in hard water bottoms and rivers and lakes lacking in plant growth substrates. Background technique [0002] Ecological restoration of rivers and lakes usually refers to the use of different technical means and methods to improve the habitats of rivers and lakes according to the degree of damage to the river and lake environment and ecosystem, and to restore the river and lake ecosystem to an approximate state before it was destroyed, and A complex process capable of self-sustaining ecosystem stability. The premise of freshwater ecosystem restoration is habitat restoration, and then the introduction of aquatic vegetation to establish an ecosystem with aquatic plants as the main primary producers. The purpose of habitat restoration is to improve the stability of the physical and chemical environment of the e...
