| 中文摘要: |
| 为寻求杂交小麦西杂一号的最佳高产栽培方案，采用三因子二次饱和D 最优试验设计，选取对小麦产量影响较大的播期、基本苗和施肥量为调控因子，建立杂交小麦产量模型，筛选高产优化栽培方案。结果表明，在本试验条件下，影响杂交小麦西杂一号产量的各因素权重依次为施肥量＞基本苗＞播期；三因素间对杂交小麦产量具有正向的互作效应，且施肥量与播期的互作最大，播期与基本苗的互作较小。依据建立的数学模型，目标产量在7 500～9 000 kg·hm-2时，杂交小麦西杂一号高产的最佳栽培方案为：施肥量（N∶P2O5=1∶1）219.45～328.24 kg·hm-2，基本苗为 226.84万～318.24万株·hm-2，播期为 10月6日-20日。 |

| In order to establish the optimized high yield production model for hybrid wheat Xiza1,the quadratic saturation D optimal design was used with three factors of sowing date, basic seedlings and fertilization. The results showed that, in the experimental conditions， the impact of the agronomic measures on hybrid wheat Xiza1 production by weights were as fertilization>basic seedlings>sowing date.There were positive interactions between those three factors with the biggest between sowing date and fertilization.Based on the mathematical model established, to obtain the target yield of 7 500~9 000 kg/hm2,for hybrid wheat Xiza1, the optimized agronomic measures were:219.45~328.24 kg·hm-2 pure fertilizer of N,P(N∶P2O5=1∶1),226.84×104~318.24×104 basic seedlings·hm-2, and sowing date at October 6~20. |
