| 摘 要： | 试验于2007/2008年度在北京市昌平区进行,采用5因子4水平的田间试验方案研究不同氮磷钾、有机肥和灌水量的组合对小麦产量的影响。方差分析表明,各因素对产量的影响顺序为氮肥灌水钾肥有机肥磷肥,同时存在交互作用;水分和产量成较好的正相关,有机肥对产量的提高虽然不如氮肥、钾肥和灌水,但是对产量的影响也达到了极显著水平;在各种组合中,以施氮量为75kg.hm-2配合12000kg.hm-2的有机肥、75kg.hm-2的磷肥、150kg.hm-2的钾肥以及3000kg.hm-2灌水量处理的产量较高,为本年度最佳水肥组合。

| Abstract: | To study the effects of different combinations of nitrogen,phosphorus,potash,organic fertilizers and irrigation on winter wheat yields,the field experiments were conducted in Changping,Beijing from 2007 to 2008.The results showed that the effects of each factor was nitrogen>irrigation>potassium>organic fertilizer>phosphorus,and interaction was still existed.There was positive correlation between irrigation and yields.Organic fertilizer had a significant relationship with yields,though its effect was less th... |
