摘 要:构建一种北方稻渔综合种养新模式并进行经济效益分析,该模式在稻蟹生态种养的基础上,添加了南美白对虾、中华长臂虾和鲢鳙鱼。结果表明,此模式2022年和2023年水产生物中产值最多是河蟹,达到31212元/hm2和32965元/hm2,产投比最大的为南美白对虾,两年分别为17.74和21.32。此模式比水稻单一种植模式增收27809元/hm2和29329元/hm2,对综合效益有正面作用。A new mode of integrated farming of rice and aquaculture animal in the north was constructed and economic benefits were analyzed.On the basis of rice-crab ecological mode,this model added pacific white shrimp(Penaeus Vannamei),Chinese grass shrimp(Palaemonetes sinensis)and silver carp and bighead carp.The results showed that the highest profit among aquatic products in this model in 2022 and 2023 was crab,reaching 31,212 yuan/hm2 and 32,9652 yuan/hm2.The largest input-output ratio was white shrimp,which was 17.74 and 21.32 respectively in the two years.Compared with the rice monoculture model,this new model increased the income by 27,809 yuan/hm2 and 29,329 yuan/hm2,which had a positive effect on the comprehensive benefits.
