优良食味水稻南粳3908机插同步侧深施肥减氮增效技术示范与应用

Study on Nitrogen Reduction and Efficiency Improvement Technology of Synchronous Side-deep Fertilization with Mechanical Transplanting for Good Taste Rice Variety Nangeng 3908

水稻机插同步侧深施肥技术是农业农村部确定的重大引领农业技术,具有节本增效、高效环保的突出优势,是今后稻作技术的发展方向之一。优良食味水稻品种是优质稻米产业发展的重要基础,研究示范和推广优良食味水稻机插同步侧深施肥技术对优质稻米产业具有重要的意义。本示范在水稻常规生产施氮量减少15%以上的基础上,总结了机插同步侧深施肥下南粳3908产量达9 750~10 500 kg/hm^(2)的生产指标和优质高产栽培关键技术,开展了应用实例分析,为该项技术的推广应用提供了切实可行的指导依据。

The synchronous deep-side fertilizing technology in mechanical transplanting is a major leading agricultural technology determined by the Ministry of Agriculture and Rural Affairs,which has the advantages of saving cost and increasing efficiency,high efficiency and environmental protection,and is one of the developmental directions of rice cultivation technology in the future.Rice varieties with good taste are the important basis for the development of high-quality rice industry.Therefore,it is of great significance to study and formulate the technical regulation of mechanical transplanting and simultaneous side-deep fertilization for high-quality rice industry.In this study,on the basis of reducing nitrogen application rate by more than 15%compared with conventional production,we explored the fertility index of 9750~10500 kg/hm^(2) and the technology of high-quality and high-yield cultivation for Nangeng 3908.The application example was analyzed,which can provide a practical and feasible guidance basis for the popularization and application of this technology.
