摘    要:采用水域浮床无土种植方法,以人工模拟池为试验场所,在池内的富营养水水体表面种植水稻,通过水稻的吸收和吸附作用,去除水体中的N、P元素,以实现变废为宝,净化水质,并使水体产生良性循环。

关 键 词:水稻  浮床  富营养化      水体污染  污染治理

Abstract:Experiments were carried out in artificially eutrophicated water bodies in cement ponds with the concentrations of TP at 0.248 mg/L and KN at 2.084 mg/L and without any interference from natural environment. On the surface, rice was transplanted on floating beds for the purpose of removing nutrients from water by adsorption of rice roots so that excessive nutrients could be utilized usefully. At the meantime, water could be purified and the benign recycling of water bodies could be maintained. When the floating bed coverage rates were set up at 20%, 40% and 60% in about 1.4 m of water depth, for the period of 84 days from tellering to harvest stage, the removal rates of TP and KN in water reached 32.1%, 42.0% and 49.1%, 29.0%, 49.8% and 58.7%, respectively. The results show that the design is not only feasible but also effective, providing the scientific basis for applying terrestrial economic plants on flaoting beds to purify eutrophicated water bodies.
