| 摘 要： | 采用二次回归通用旋转组合设计方法,对大麦新品系F0797在四川德阳地区的最佳栽培技术模式进行了研究,建立了播种量(X1)、播种期(X2)、磷肥用量(X3)、氮肥用量(X4)与产量的数学回归模型:Y=469.286-5.486X1-3.125X2-2.015X3+44.235X4-9.040X12-12.374X22+1.376X32-7.165X42+15.938X1X2-6.146X1X3-9.479X1X4+10.729X2X3-5.522X2X4-5.103X3X4 .显著性检验表明该模型拟合较好,可靠程度较高.对该模型解析显示,F0797产量≥450 kg/667 m2 的优化农艺措施组合方案为:播种量14～15 kg/667 m2,播期11月3～5日,P2O5用量9～11 kg/667 m2,纯氮用量12～13 kg/667 m2 .四个参试因素中,以氮肥对产量的贡献最大,其次是播种量、播种期,磷肥对产量的影响相对较小.
