稻鱼共作对养殖池塘沉积物-水界面微观剖面理化性质的影响
Impacts of Rice-Fish Co-culture on the Physical and Chemical Variables of the Microprofiles at Sediments-Water Interface in an Intensive-culture Pond
摘要
Abstract
An experiment was carried out to investigate the physical and chemical variables in sediment-water interface of yellow catfish pond with and without rice planting.The results showed that rice-fish co-cultures slowed down the decrease of O 2 concentration around the sediment-water interface,and increase the O 2 penetration depths by 71 .4%, comparing with fish monoculture pond.Additionally,rice-fish co-culture increased the Eh value,and improved the aerobic condition in the sediment of pond.Rice-fish co-culture also decreased the pH around sediment-water interface. The pH of rice-fish co-culture pond was lower than that of monoculture pond by one unit.These results indicated that rice growing changed the mocroenvironment of the sediment-water interface of fish pond,which may affect the migration and transformation of elements around this interface.关键词
