| 摘 要： | 稻鱼共作技术是中国传统农业的精华,通过对稻鱼共作系统水体浮游植物的种类组成、密度、生物量及多样性进行分析,明确该系统中浮游植物数量变化特性,为进一步开发利用这一经典农艺提供理论基础和实践依据。结果表明,稻田生态系统中浮游植物群落包含蓝藻门、甲藻门、隐藻门、裸藻门、绿藻门和硅藻门等6门,共38属93种。稻鱼共作显著增加稻田水体浮游植物的密度和生物量,降低硅藻和蓝藻的优势度,增加绿藻和裸藻的优势度,提高了稻田水体浮游植物多样性指数。

| Abstract: | The rice-fish ecological system is one of the classics practices from the traditional Chinese agriculture.The species composition,density,biomass and diversity of phytoplankton in rice-fish ecological system were investigated to reveal its quantitative characteristics and provide theoretical and practical basis for further development and utilization of this classical agricultural technique.The results showed that there were 6 phyla,38 genera and 93 species in the plots,including Cyanophyta,Chlorophyta,Baci... |
