摘　　要：应用稻鱼共生理论和池塘精养鱼高产技术,把坑塘式稻鱼兼作与田塘式稻田养鱼轮作技术有机结合,创立了稻鱼生态兼作轮作一体化优质高产技术模式,有鱼种培育和成鱼养殖2种子模式。在福建省连城县隔川乡松洋村建立了该模式的示范基地20hm2,生产结果表明,与稻田种植双季稻不养鱼比较,2种子模式的早稻单产平均增产了22%,增产效果极显著(P<0.01);鱼种培育子模式,稻田产鱼种6795kg/hm2、产值77730元/hm2、纯收入24930元/hm2,产值提高了2.5倍、纯收入提高了3.7倍(P<0.01);成鱼养殖子模式,稻田产鱼10650kg/hm2、产值96420元/hm2,纯收入30075元/hm2,产值提高了3.2倍、纯收入提高了4.7倍(P<0.01);取得了良好的经济、社会及生态效益。Based on the Rice Fish Concurrent living theory and pond aquaculture high yield technology, combining Rice Fish Concurrent Farming technique in the model of pit pond aquaculture and the Rice Fish in turn Farming technique in the model of field pond aquaculture, the high quality and yield ecological technique model of early rice fish concurrent farming and late complete aquaculture in paddy field was established, which contain one submodel of fingerlings farming to juvenile and another submodel of juvenile fish farming to adult fish. The model demonstration base covering 20 hm2 paddy field was established in Songyang village, Gechuan town, Liancheng county of Fujian province. Production results showed： Early rice harvest average yield increased 22% very significantly （P 〈 0. 01 ） in both submodels, and 453 kg juvenile fish was produced per 667 m2 paddy field implementing the submodel of fingerlings farming to juvenile fish, whose production value and profit were 5 182￥ and 1 662 ￥ RMB, respectively, and were very significantly increased 2.5 times and 3.7 times （P 〈 0.01 ） respectively than planting only two harvests paddy without aquacuhure; 710 kg adult fish was produced per 667 m2 paddy field implementing the suhmodel of juvenile fish farming to adult fish, whose production value and profit were 6 428￥ and 2 005 ￥ RMB, respectively, and were very significantly increased 3.2 times and 4.7 times （P 〈 0. 01 ） respectively than planting only two harvests paddy without aquaculture; There were good economic, social and ecological benefit.
