摘　　要：应用二次回归正交旋转组合设计，选择秧田播种量、插植密度、Ｎ、Ｐ、Ｋ施用量等５个栽培因子，研究优质早籼舟９０３高产数学模型及优化农艺方案的结果，舟９０３亩（６６７ｍ２，下同）产５００ｋｇ以上的优化农艺方案为：每亩秧田播种量３８８５～４０２６ｋｇ，插种２６２～２６８万丛，施纯Ｎ１１２２～１１７０ｋｇ，Ｋ２Ｏ３３２～３５３ｋｇ，Ｐ２Ｏ５３９０～４１５ｋｇ。A current, rotational and combinational design of quadratic with different rates of seeding, planting density, N, K and P was carried out to study the high yielding mathematical model of cultivation technique and its optimum scheme of agrotechnique of quality early rice zhou 903. The results showed that the optimum scheme of yield (more than 500kg/mu) of zhou 903 was 38.85～40.26kg per mu for seeding, 26.2～26.8 thousand hills per mu, 11.22～11.70 kg N, 3.32～3.53kg K 2 O and 3.90～4.15kg P 2 O 5 per mu for fertilizer.
