摘要
针对有机质浮岛水面复合种养模式增氧效果的比较,设计并制造了一种有机质浮岛智能增氧系统。为探究在日常增氧需求时不同增氧方式对该模式池塘溶氧调控的影响,应用3种不同增氧方式进行增氧效果试验,结果表明:3种增氧方式均对池塘水体溶氧量有积极作用,由于浮岛固有的消浪作用导致耕水机和叶轮式增氧机扰动水体能力降低,从增氧效果来看,有机质浮岛增氧系统>叶轮式>耕水机。通过对不同增氧方式的综合对比,旨在为浮岛生产中增氧方式的合理选择提供参考。
This study is a comparative study on the aeration effect of the compound planting and breeding mode of organic matter floating island.The experimental design of the influence of this model on the regulation of dissolved oxygen in ponds is as follows:Three different aeration methods are used to carry out aeration effect tests.The results show that all three aeration methods have a positive effect on the dissolved oxygen in the pond water body,due to the inherent characteristics of floating islands The wave-dissipating effect causes the water cultivator and the impeller aerator to reduce the ability to disturb the water body.From the perspective of the aeration effect,the organic matter floating island aeration system>impeller type>cultivator.Through a comprehensive comparison of different aeration methods,it provides a certain reference value for the reasonable selection of aeration methods in the production of floating islands.
