摘要: 通过对蒙啤麦一号大麦氮、磷、钾及密度合理的田间配比试验,建立四因素二次回归数学模型,为蒙啤麦一号在黄灌区的大面积示范、推广。集成该品种高产、优质、高效栽培技术提供理论支持。试验研究结果表明:在内蒙古巴彦淖尔市黄灌区施用配比合理的氮、磷、钾肥及密度对蒙啤一号大麦的丰产性有显著作用,运用二次回归数学模型进行推算,最高理论产量可达723.2109kg/667m^2,氮、磷、钾及密度配比为氮肥8.0kg/667m^2,磷肥8.0kg/667m^2,钾肥2.5kg/667m^2,播种量21.1kg/667m^2(千粒重为50g);最佳产量为549.7956kg/667m^2,与之相匹配的四因素配比为氮肥7.093kg/667m^2。磷肥3.730kg/667m^2,钾肥4.580kg/667m^2,播种量20.5kg/667m^2(千粒重为50g)。

Abstract: By field comparing trail on proportion of N,P,K, and density of Mengpiyihao barley in Hetao irrigated area of Inner Mongolia, a 4-factor and 2-degree regression model was set up, which can offer the theoretical basic for high quality and high yield of Mengpiyihao barley in Hetao irrigated area. The Results showed there was a obvious effect on yield by rational application of N,P,K and Density. According to mathematic model, when N:8.0000kg/667m^2,P2O5:8.0000kg/667m^2, K2O: 2.5000kg/667m^2,sown seed amount: 21.1261kg/667m^2 (50g/1000seeds), the highest yield can reach to 723.2109kg/667m^2 .When N: 7.093kg/667m^2,P2O5:3.730kg/667m^2, K2O:4.580kg/667m^2,sown seed amount: 20.520kg/667m^2 (50g/1000seeds), the optimum yield was 549.7956 kg/666m^2.
