摘要
采取正交二次回归旋转组合设计试验，研究了特优 ５５９ 主要农艺措施对产量的影响效应，建立了产量对移栽密度、追肥施氮量、蘖肥占追肥比例的三因素的函数模型。分析了主要农艺措施的各自效应与互作效应；筛选出具有高概率保证的高产高效的栽培技术组合。
An orthogonal quadratic regression model was used to study the effects of main agronomic measures on yield of Teyou 559 and established a functional model of yield on transplanting density, rates of N fertizer in topdressing and the ratio between the amount of fertizer in tillering and the amount of topdressing main effects and interaction of agronomic measures on yield were analysed and high yielding and efficient measure combinations were screened.
