Process for harnessing eutrophication water body by interplanting plant on water

Abstract

The invention discloses a method for treating eutrophic water bodies by aquatically interplanting cultivated plants. Bamboo slices with an interval of between 10 and 15cm are taken as materials and are produced into a rectangular frame, and the plane of the frame is bound with a nylon net to form a floating floor; a nurtured high plant with a 50cm stubble height on the ground is transplanted to be among the bamboo slices of the frame, a creeping plant is transplanted onto the nylon net, and the high plant and the creeping stem plant are periodically reaped. The method has small investment andconvenient management; moso bamboos are taken as materials, and have high amalgamation degree with the environment after the moso bamboos are placed into water due to the natural color and luster of the moso bamboos; compared with the prior foam plastic and PVC carrier, white visual pollution can not be formed, and no secondary pollution exists. A carrier has long service life, provides conditions for the recovery of a water body all the year around, and can save cost. The method has flexible matching selection of plant interplanting, can also improve the immunity of crops, reduce the attack of plant diseases and insect pests, and has wider applicable regions, which have important significance to the scale of aquatic cultivated plants and the in-situ recovery of the eutrophic water bodies.

Description

technical field [0001] The invention relates to a treatment method for eutrophic water bodies, in particular to a method for treating eutrophic water bodies by intercropping tall stems and stolon plants on water. Background technique [0002] Eutrophication of water body has become a worldwide environmental problem. According to a survey by the International Lake Environment Council (ILEC), most lakes in the world are suffering from eutrophication in varying degrees, with 54% in the Asia-Pacific region, 53% in Europe, 28% in North America, and 41% in South America. Among the 131 major lakes in my country, 67 lakes have reached the eutrophic level, accounting for 51.2%; among the 39 representative reservoirs, 12 have reached the eutrophic level, accounting for 30%. Among the five major freshwater lakes, Taihu Lake, Hongze Lake, and Chaohu Lake have reached the eutrophication level. Although Poyang Lake and Dongting Lake maintain the mesotrophic level at present, their phosph...

Problems solved by technology

At present, the most widely used carrier materials are foam plastics, PVC, etc., but the materials are generally white, which can easily cause visual pollution, increase the cost of dyeing materials, and easily pollute water bodies; due to the characteristics of the material itself, its aging speed is relatively fast , and the current aging materials can not be well resourced, so the waste materials are easy to cause secondary pollution to the environment
