稻虾轮作模式经济效益与技术需求分析

Analysis of Economic Benefit and Technical Demand of Rice Shrimp Rotation Mode

近年来,稻虾轮作模式推广迅速,已成为规模化经营主体广泛应用的综合种养模式。采用调查研究方法,研究了稻虾轮作模式的经济效益,分析了该模式的技术需求,以期为湖南省或其他地区稻虾轮作模式健康发展提供参考。结果表明:相较于中稻单作模式,稻虾轮作模式提高了水稻的产量和品质,增加了虾的产出,总收益提高了4.26万元/hm^2,产投比提高了0.97;在种虾繁育、病虫害绿色防控、水肥管理、饲料投喂以及水质调控和检测等方面存在技术需求。因此,应加强产学研合作,突破关键技术瓶颈,以促进稻虾轮作模式的可持续发展。

In recent years,rice shrimp rotation mode has been popularized rapidly,and has become a comprehensive planting and breeding mode widely used by large-scale management subjects.The economic benefits of rice shrimp rotation model were studied by investigation,and the technical requirements of the model were analyzed in order to provide reference for the healthy development of rice shrimp rotation model in Hunan Province or other regions.The results showed that the rice shrimp rotation mode improved the yield and quality of rice,increased the output of shrimp,increased the total income by 42600 yuan/hm^2,and increased the ratio of yield to investment by 0.97.There are technical requirements for improving the survival rate of shrimp seedlings,strengthening the green prevention and control of diseases and insect pests,reasonable water and fertilizer management and feed feeding,and strengthening water quality control and detection.Therefore,we should strengthen the cooperation of production,education and research,break through the bottleneck of key technologies,so as to promote the sustainable development of rice shrimp rotation mode.
