Submerged plant hard-bottom point-hitting planting technique

Abstract

The invention relates to a technology of punching at a hard bottom for a submerged plant and belongs to the technical field of water ecological rehabilitation. The pointed culturing of the submerged plant can be realized under the conditions of a hard substrate and an extremely low water transparency by the collection, sorting, culture pan culturing, underwater punching and planting of a germchit; the technology is simple and easy, has a high surviving rate, can change the partial water quality condition by scale planting, realize the self-surviving and developing as well as achieve the goals of improving the environment and rehabilitating the ecology. The technology is particularly suitable for culturing the pioneer species of the submerged plant in a water ecological rehabilitation project under the covering condition of seasonal cyanobacterial blooms caused by the eutrophication of lakes. The adaptive water depth can achieve more than 3m.

Description

(1) Technical field [0001] This technology belongs to the technical field of water body ecological restoration, and can be applied to the cultivation of pioneer species of submerged plants in the ecological restoration of lakes, reservoirs, rivers and other water bodies. (2) Background technology [0002] Submerged plants are an important part of the aquatic ecosystem. They have a very high specific surface area, provide space for other organisms to inhabit and attach, and can release oxygen through photosynthesis. Existing research results have proved that submerged plants can improve Water quality, inhibition of cyanobacteria blooms, and protection of lake biodiversity have significant effects, and have become a major content of water ecological restoration. [0003] In the existing ecological restoration projects, submerged plants are planted mainly by methods such as throwing seeds and planting seedlings, which are highly dependent on environmental conditions such as wat...

AI Technical Summary

Problems solved by technology

[0003] In the existing ecological restoration projects, the planting of submerged plants mainly adopts methods such as throwing seeds and planting seedlings, which are highly dependent on environmental conditions such as water depth, transparency, and substrate, and have poor ability to resist wind and waves, and the survival rate is low. However, in many areas, due to unfavorable factors such as large water depth, low transparency, and sandy hard bottom, it is difficult for submerged plants planted in conventional methods to survive, which seriously affects the implementation effect of ecological restoration.
