| 摘 要： | 目的]探讨青海省不同生态区栽培措施对青稞产量的影响。方法]以昆仑12号青稞品种为试材,采用3因素饱和-D最优设计,研究青海省西宁市和门源县两地青稞产量与氮肥施用量、磷肥施用量和播种量3项栽培措施应用水平的量化关系。结果]西宁市各试验因素对青稞产量的影响依次为磷肥施用量、氮肥施用量、播种量,因子间互作效应表明氮肥施用量和播种量对产量的影响较强,最佳栽培方案组合为纯氮施用量、纯磷施用量和播种量分别为77.250~114.450 kg/hm2、35.100~52.650 kg/hm2、150.000~187.500 kg/hm2;门源县各试验因素对产量的影响依次为播种量、氮肥、磷肥,因子间互作效应表明对产量的影响因素为氮肥施用量和磷肥施用量,最佳栽培措施方案组合为纯氮施用量、纯磷施用量、播种量分别是49.050~99.600 kg/hm2、44.100~65.700 kg/hm2、262.500~318.750kg/hm2。结论]为青藏高原青稞高产优质的规范化栽培提供依据。
