采用四因子五水平二次正交回归旋转组合设计 ,研究了水稻密度、氮、磷和钾用量与产量、生产成本、产投比和净效益的关系 ,建立了重穗型杂交水稻冈优 15 1产量 (Yl)、生产成本(Yc)、产投比 (Yt)和净效益 (Yj)与密度、氮、磷和钾规格用量之间的数学模型 ,在对模型解析的基础上 ,进行计算模拟研究和优化选择 ,提出了重穗型杂交水稻冈优 15 1超高产高效栽培的密度与氮、磷、钾施肥技术方案。
The quadratic orthogonal quadratic regressive rotation combination design of four factors and five levels was used to study the relationship between rice density, N, P and K dosage and yield, production cost, production-to-input ratio and net benefit. Based on the model analysis, the mathematical model between Yl, Yc, Yt and Yj and the density, nitrogen, phosphorus and potassium content was calculated Simulation research and optimization selection, put forward the plan of the density, nitrogen, phosphorus and potassium fertilization of the heavy panicle type hybrid rice Gangyou 15 1 in super high yield and high efficiency cultivation.
