摘要
依据陆生植物的养分吸收特性,利用水上种植技术,在以富营养化为主体的污染水域种植粮油、蔬菜、花 卉等各种适宜的陆生植物的同时,通过植物根系的吸附和吸收作用,富集水中导致水域富营养化的主要 因素--氮、磷等元素,降解、富集其他有害无毒污染物,并以收获植物体的形式将其搬离水体,从而实 现变废为宝、净化水体、美化水域景观、保护水生态环境的目的。
Based on characteristics of land plants of absorbing nutrients, water -planting technology was used for implantating suitable land plants in water, such as grain, oil crops, vegetables and flowers in eutrophication polluted areas. Nitrogen and phosphorus that caused enrichment of water bodies can be absorbed by the plants root system that degrade the harmful but nonpoisonous pollutants, and then be removed through plants harvesting. As a result water bodies are cleaned, converting useless to be utilized, ecosystem is also protected at the same time.
