藻类对池塘水环境的影响及水生植物和鲢鳙对水体的净化
Effects of Algae on Pond Water Environment and Purification of Pond Water by Aquatic Plants and Silver Carp and Bighead Carp
摘要
Abstract
Effects of nitrogen and phosphorus on algal growth and water environment factors were studied by using culture pond. The results show that the increase of nitrogen and phosphorus in water body promoted the growth and propagation of algae. Algal metabolism had effects on dissolved oxygen and pH value in water, and chlorophyll a showed a significantly positive correlation with dissolved oxygen and pH value. The increase of algal photosynthesis increased oxygen content in water body. Carbon dioxide absorption of algae had effects on the balance between carbonic acid and carbonate concentration in water, causing pH of water to be alkaline. Oxygen accelerated the nitrification and denitrification process, improving the growth of plants. Nitrogen 1 207. 5 g was extracted by 42. 67 kg silver carp and bighead carp and removing nitrogen 0. 905 mg/L from water, extracting 88. 4 g phosphorus and removing 0. 066 mg/L. It is proved that plankton, aquatic plants and fish play an important role in regulating ecological environment of water body.关键词
