摘要

[目的

]

探究植物的交互作用对生态浮床去除N，P效率的影响，为后期南海湖湿地规模化建设提供理论依据。[方法

]

在自然开放水域条件下，选取适合于北方生长的3种挺水植物水葱、千屈菜、风车草为浮床植物，以高密聚乙烯空心塑料基盘为植物载体，建立单一种植与交叉混合种植两种浮床体系，在南海湖湿地保护区进行为期90 d的水质处理，研究植物生长特性及浮床净化效果。[结果

]

10月份收割时，混合浮床中水葱和风车草的分蘖数分别达26和30株，生物量（鲜重）分别为1.43和1.98 kg/株。风车草浮床N累积量最好，达110.6 g/m

，水体TN去除率34.9%。混合浮床P累积量最好，达26.02 g/m

，水体TP去除率43.3%。[结论

]

植物的交互作用对植株的分蘖繁殖有一定促进作用，但不改变植物自身N，P吸收能力，植物体对N，P的累积量受生物量影响较大，3种植物在混合浮床中的整株N，P累积量要高于单植物浮床，混合浮床可作为针对南海湖富营养化水体修复的浮床形式推广使用。

Abstract

[Objective] The interaction of plants on the removals of N and P efficiency by ecological floating bed was studied to provide a theoretical basis for the large-scale construction of Nanhai Lake wetland in the later period.[Methods] Under the condition of natural open water

three kinds of water-stained plants

Scirpus validus

Lythrum salicaria

and Cyperus alternifolius

which are suitable for growth in the north

were selected as floating bed plants

and high-density polyethylene hollow plastic substrates were used as plant carriers

to establish two kinds of floating bed systems of single planting and mixed planting in the Nanhai Lake Wetland Reserve for 90 days of water treatment to study plant growth characteristics and floating bed purification effects.[Results] At the time of harvest in October

the number of tillers of Scirpus validus and Cyperus alternifolius in the mixed floating bed reached 26 and 30

respectively

and the biomasses (fresh weight) were 1.43 kg/plant and 1.98 kg/plant

respectively. The cumulative amount of Scirpus validus grass floating bed N was the best

reaching 110.6 g/m2

and the water body TN removal rate was 34.9%. The cumulative amount of mixed floating bed P was the best

reaching 26.02 g/m2

and the water body TP removal rate was 43.3%.[Conclusion] The interaction of plants can promote the tillering of plants

but it does not change the N and P absorption capacity of plants. The accumulations of N and P in plants were greatly affected by biomass

and the individual accumulations for the three plants in mixed floating bed were greater than those in single floating bed. The mixed floating bed can be used as a floating bed for the restoration of eutrophic water in Nanhai Lake.
