摘要
[目的]探讨稻渔综合种养在稳粮、促渔、环境友好等方面的生态功能。[方法]通过克氏原螯虾、水稻、鳜鱼共作模式,从经济、生态效益、农业风险评估角度探讨了生态种养融合技术。[结果]通过虾、水稻、鳜鱼共作,利润达到77 125元/hm2,较水稻单作提高了10倍;农业生产过程中不需要使用农药,少量施肥,养殖模式绿色环保,产品品质接近天然;多品种综合种养农业风险较低,且效益稳定。[结论]该模式是对传统稻虾连作种养模式的突破,生态环保,能提质增效。
[Objective]To study the ecological functions of integrated technology of rice and aquaculture,such as stabilizing food,promoting the fishing,and friendly environment.[Method]The co-culture model of shrimp-rice-mandarin fish was discussed from the aspect of economic benefit,ecological benefit,and agricultural risk assessment.[Result]The average net profit of co-culture model of shrimp-rice-mandarin fish reached77125Yuan/hm^2,which increased by10times than that of single rice planting model.No pesticide and less fertilizer were used in the agricultural production process,the co-culture model of shrimp-rice-mandarin fish was green,and agricultural products were natural.The co-culture model of shrimp-rice-mandarin fish had low agricultural risk and stable benefit.[Conclusion]This co-culture model of shrimp-rice-mandarin fish was a breakthrough to the traditional shrimp-rice continuous cropping pattern,it was beneficial to ecology environmental protection and promote the quality enhancement.
