| 摘 要： | 在长期定位施肥的基础上,主要探讨了长期施用秸秆与化肥在2006年对冬小麦产量及其穗部性状的影响.结果表明:冬小麦在施用不同量的化肥和秸秆处理下产量差异明显,施用化肥的增产幅度远远大于施用秸秆肥,而秸秆与化肥配施对小麦的增产作用最大;通过对穗部性状分析结果发现,秸秆与化肥配施对小麦的显著增产作用主要来源于小麦穗密度的增加,而穗粒重对小麦产量影响较小.

| Abstract: | The experiment has being conducted at the experimental farm of Institute of Dryland Farming, Hebei Academy of Agriculture and Forestry Sciences since 1981. The results showed that the chemical fertilizer had more influences on the winter wheat yield and the spike characters than straw. But the combination straw and chemical fertilizer had active influence on winter wheat yield and the spike characters. The analysis passing to spike characters is reached, the straw and chemical fertilizer increasing the production by executing the spike density, but the output to the wheat is less in effect in grain weight. |
