| 摘 要： | 为寻求最佳栽培因子组合,为小麦增产提供科学依据,在陕北黄土高原川地中等肥力条件下,进行了三因素二水平正交设计试验。研究表明,三因素对小麦产量影响顺序为施肥量>种植方式>播种量。同时研究了播种量与施肥量、播种量与种植方式、施肥量与种植方式之间的交互作用。小麦品种石86-51446000 kg.hm-2以上栽培方案为:播种量120 kg.hm-2,施氮量189 kg.hm-2,施磷量129 kg.hm-2,并进行地膜覆盖。

| Abstract: | The field experiment of three factors and two levels with crossed design was carried out at medium soil fertility condition on Northern Shaanxi plateau.The effect sequence of three factors on wheat yield was showed that planting way>fertilizer>sowwing norm.The interaction effects of sowwing norm with fertilizer,sowwing norm with planting way and fertilizer with planting way were analysed.The result showed that the cultural techniques of maximum yield at more than 6 000 kg·hm-2,sowwing norm was 120 kg·hm-2,nitrogen fertilizer dose was 189 kg·hm-2,phosphate fertilizer dose was 129 kg·hm-2,planting way was covering film in winter wheat. |
