由浙江省农科院土肥所主持完成的稻、萍、鱼共生高产技术开发研究,经几年来的大面积多点应用验证,经济、社会和生态效益显著,已于1990年底通过鉴定。此项研究是在对传统稻田养鱼和稻田养萍技术进行改革的基础上,以形成良好的共生生态环境为目的,与稻田工程设计相结合,进行综合的配套技术研究。表明在粮食尚能增产0.2—4.8%的基础上,亩产鲜鱼比
The research and development of symbiotic and high-yielding technologies for rice, ping and fish hosted by the Department of Soil and Fertilizer, Zhejiang Academy of Agricultural Sciences has been verified by the application of large-scale multi-point application in recent years with remarkable economic, social and ecological benefits. Based on the reform of traditional paddy farming and rice paddy cultivation techniques, this study aims at forming a good symbiotic ecological environment and combining with paddy field engineering design to carry out comprehensive and complementary technical research. This shows that the grain yield is still 0.2-4.8%, based on the yield of fresh fish per mu
