Aquatic plant patch growth water ecology restoration method

Abstract

The invention discloses an aquatic plant patch growth water ecology restoration method. The method comprises the following steps: selecting 4-10 types of aquatic plants as water ecology restoration plants; selecting a square region with the side length of 0.8-1.2m, and growing 60-120 plants of one type of the water ecology restoration plants in water sediment in the region in a cuttage mode, thereby obtaining a patch 1; selecting another square region with the same area in the position which is twice of side length of the side edge of the patch from the patch, and growing one or different types of water ecology restoration plants in the region, thereby obtaining a patch 2; circulating like this to obtain an array composed of a plurality of uniformly distributed patches, thereby forming a patch community; and continuing growing according to the method until all the water ecology restoration plants are grown, thereby forming a plurality of water ecology restoration plant patch communities, wherein all the water ecology restoration plant patch communities are distributed closely to each other. The method is capable of enhancing the survival percent of the plants, increasing the restoration efficiency and obviously lowering the comprehensive restoration cost, and is simple to operate and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of water ecological restoration and plant optimization planting configuration, and in particular relates to a water ecological restoration method for patch planting of aquatic plants. Background technique [0002] In recent years, with the rapid development of industrial and agricultural production and the acceleration of urbanization, the amount of industrial wastewater and domestic sewage discharged into water bodies and lakes has continued to increase, large areas of vegetation in lake water have disappeared, and the degree of eutrophication of water quality has become increasingly serious, prompting algal blooms. Rapid reproduction, some of the algae will emit a fishy smell, when the algae die and decompose, the COD and BOD values ​​​​in the water will increase sharply, the water quality will deteriorate, and the transparency of the water body will be greatly reduced. [0003] my country's water ecosyste...

Problems solved by technology

However, since the growth of aquatic plants is easily affected by seasons, the removal efficiency of pollutants is also easily affected by seasons. In addition, due to the complex growth inhibition, physical effects, allelopathic effects, and natural death and renewal of plants themselves among aquatic plant species , often resulting in low plant survival rate, unstable water quality treatment effect, slow repair speed, and low repair efficiency
