Abstract:

In order to determine the optimum planting area of lotus in integrated lotus-Chinese soft-shelled turtle culture, the phytoplankton community structure and biodiversity were studied in four patterns of lotus planting area percentage (Type A-10%, Type B-30%, Type C-50% and Type D-70%) by biodiversity methods. The results showed that 48 genus 75 species of algae were detected in Type C, and the absolute dominant species was Chlorophyta (Chlorella, Scenedesmus, etc.), with an average density of 151442 ind/L and an average frequency of 69.89%. The average number of Chlorophyta in Type C was significantly higher than that in type A, B(>LSR0.01) and D (>LSR0.05). The phytoplankton Shannon-Wiener diversity index H, Pielou uniformity index E and Simpson dominance index D were the highest, with the average value of 2.188, 0.949 and 0.841, respectively. Therefore, the community and the biological diversity of Type C with 50% lotus roots planting area are more complex, and the water is more stable.
