Abstract

The invention provides a submerged plant modularized growth bed and a method for recovering growth of underwater submerged plants. The submerged plant modularized growth bed comprises suspended solids, planting layers, plant layers, a growth substrate layer, a bearing layer and balance weight facilities, the submerged plant modularized growth beds are mutually connected to form an entire piece, micropores are formed in the bearing layer so that roots of the plants can penetrate through, the growth substrate layer adopts planting soil, the periphery of the planting layer is fixedly connected with the periphery of the bearing layer, the planting layers and the bearing layer wrap the growth substrate layer, the suspended solids are fixedly arranged around the submerged plant modularized growth bed, each suspended solid is hollow and is filled with air, and the balance weights are fixedly arranged at the lower end portion of the suspended solids to keep the depth of the modularized growth bed suspending on the water surface. The submerged plant modularized growth bed is reasonable in design, compact in structure, simple to manufacture, low in cost, simple to operate and convenient to manage, and the submerged plant modularized growth bed is degraded along with the growth of the underwater submerged plants, is free of pollution, protects the environment, is wide in application range, is widely popularized conveniently, and is favorable for recovery of the underwater submerged plants in different water areas.

Description

technical field [0001] The invention relates to a submerged plant growth bed, in particular to a submerged plant modular growth bed and a method for restoring the growth of submerged plants at the bottom of the water. Background technique [0002] Submerged plants are one of the primary producers of aquatic ecosystems, which have an important impact on water body productivity and biogeochemical cycles, and play an important role in water ecological restoration. Submerged plants are likened to "underwater forests" and can purify water quality , Keep the water body beautiful and improve the landscape ecological environment. [0003] However, the growth and distribution of submerged plants are regulated and stressed by many environmental factors, such as light and transparency, redox environment, and nutrients. The photosynthetic characteristics such as the light compensation point of photosynthesis of submerged plants determine the maximum depth, photosynthetic output and com...
