为探究“紫云英还田+稻鱼共生”对水稻群体生长特性和产量的影响,试验以冬闲田-双季稻(CK)为对照,设置紫云英-双季稻(ZD)、冬闲田-双季稻+鱼(YD)、紫云英-双季稻+鱼(ZY)共4个处理,调查水稻叶面积指数、干物质积累量、物质积累与转运、水稻产量和产量构成指数。结果表明: 1)双季稻栽培期间,ZY处理较CK处理抽穗期的水稻叶面积指数分别增加了11.33%和50.26%,ZY处理较CK处理从分蘖期至抽穗期的光合势分别增加了12.30%~28.96%和24.00%~ 48.46%,ZY处理较CK处理从幼穗分化期至抽穗期的净同化率分别增加了25.46%和11.62%。2)YD、ZD、ZY处理均有效提高了双季稻地上部生物量,双季稻栽培期间,ZY处理的地上部...

To investigate the effects of field returning of Chinese milk vetch coupled with rice-fish symbiosis on the population growth and yield of rice,we carried out an experiment with four treatments, including winter fallow-double cropping rice (CK)as a control,Chinese milk vetchdouble cropping rice (ZD),winter fallow-double cropping rice combined with fish (YD),and Chinese milk vetch-double cropping rice combined with fish (ZY). We measured leaf area index,amount of dry matter accumulation and translocation,rice yield,and yield composition index. T...
