水稻肥床旱育稀植通过几年试验示范,已大面积推广应用。但目前针对各地生产特点研究优化群体质量的配套技术较少。为此,本研究根据凌启鸿等高产群体质量及优化控制理论,从栽插叶龄、栽插密度、肥料运筹、搁田技术等对产量形成及群体质量影响较大的因素入手,探索其与群体质量的关系,从而优选高产的主要农艺措施参数,以最大限度发挥
Rice bed dry and fertile plant through years of experimental demonstration, has been widely applied. However, at present, there are few supporting technologies for optimizing the quality of the population for the production features of different regions. Therefore, according to the quality of high-yielding population such as Ling Qixian and the theory of optimal control, this study starts with the factors that affect the yield formation and the quality of the population, such as planting leaf age, transplanting density, fertilizer management, The quality of the relationship, and thus optimize the yield of the main agronomic parameters to maximize play
