摘要
阐述了水稻(Oryza sativa L.)幼穗分化始期的判断技术,包括根据抽穗前天数、叶龄余数推算,根据叶龄指数推算,根据生育积温指数、拔节期、双零叶出叶速度判断和直接镜检等判断水稻幼穗分化始期的技术。这对于水稻栽培测报、田间管理、杂交水稻制种的花期预测和调节均有重要作用。
Technologies for determining the beginning time of rice panicle initiation were discussed,which include conducting by the projected number of days before heading and remaining leaf primordium number,judging from the leaf age index,accumulated temperature index,jointing stage,double zero leaves,speed of leaf emergence and direct microscopic examination.It would be helpful for forecasting rice growth,field management and regulation of flowering in hybrid rice seed production.
