摘要:

为了确定藕鳖种养模式中莲藕的最适种植面积,采用生物多样性研究方法,开展4种莲藕种植面积百分比(A型-10%、B型-30%、C型-50%和D型-70%)藕鳖种养水体中浮游植物群落结构特征与多样性比较研究。研究结果表明,C型藻类48属75种,平均密度和频度分别为151442个/L和69.89%;以绿藻(小球藻、栅藻等)为绝对优势种类,绿藻种类平均数极明显高于A型、B型(>LSR0.01),明显高于D型(>LSR0.05);C型浮游植物Shannon-Wiener多样性指数H、Pielou均匀度指数E和Simpson优势度指数D均最高,平均值分别为2.188、0.949和0.841。因此,种植50%莲藕的C型水体中浮游植物群落复杂程度高,生物多样性高,水体更稳定。

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.
