摘要：

为改善底层鱼类养殖池塘的水质，设计分区池塘养殖模式以改善池塘水质的效果。结果显示：分区池塘pH 7.0~7.6，下午16:00达到最大值，分区池塘与无螺贝池塘pH平均值分别稍高于不分区池塘与有螺贝；溶解氧上午9:00在6 mg/L处波动，下午16:00在10 mg/L上下波动，存在明显的昼夜变化，但分区池塘与未分区池塘溶氧变化没有显著差异；水温在6个时间段内递增，9:00测得的水温均低于16:00的水温，但分区池塘与未分区池塘水温变化没有显著差异；池塘在分区和有螺贝存在的情况下透明度最高，池塘水质良好。分区池塘是一新型养殖模式，值得进一步研究和推广。

Abstract:

To improve the water quality at the bottom layer of pond. In this paper, we did an experiment on the effect of a new farming pattern named partitioned pond on water quality improvement. The results showed that pH value ranges from 7.0 to 7.6, the maximum was at 4:00 pm. The average of pH value in area ponds and no shellfish ponds were slightly higher than unpartitioned pond and shellfish pond, respectively. As for dissolved oxygen, fluctuations in the 6 mg/L was at 9:00 am,10 mg/L fluctuated at 4:00 pm, there exists significant diurnal variation, but there was no significant differences in area ponds and unpartitioned pond. The water temperature increased in sequence of six periods, water temperature measured at 9:00 was lower than the water temperature of 16:00, but there was no significant differences in area ponds and unpartitioned pond. The transparency of the water was the highest in case of partitioned pond and pond which had shellfish. Pond water quality was good. This new partition pond culture model was worthy of further research and extension.
