| 为制定合理的猪场沼液灌溉制度，保障作物安全，利用微生物厌氧发酵系统处理过的猪场沼液，通过田间小区试验，研究了不同灌溉量、不同灌溉次数的沼液与不同用量的氮肥配施对冬小麦生长、产量、水分利用效率以及籽粒品质的影响，并对冬小麦产量进行水肥耦合的回归分析。结果表明：施肥量相同时，猪场沼液高灌（灌水定额900 m3·hm-2）处理拔节期生长指标、产量及籽粒淀粉指标显著高于低灌（600 m3·hm-2）处理，其中产量差值达19.93%，淀粉差值达9%；灌水量相同时，猪场沼液的高肥处理与低肥处理的产量无显著性差异。水分利用效率表现为低灌处理高于高灌处理。综合来看，灌水定额900 m3·hm-2和施肥量30 kg N·hm-2为最优处理。 |
| 英文摘要: |
| Irrigation with industrial and domestic sewage has increasingly become popular in most areas of China where there is short of fresh water. Unlike fresh water, biogas liquid is rich in nitrogen and phosphorus but contains other contaminants too. Irrigation with such liquid will therefore arouse concerns over food and environmental safety. A field experiment was conducted to study the effects of irrigation rates and frequency of biogas liquid in combination of two rates of nitrogen fertilizer on growth, yield, grain quality, water use efficiency（WUE） of winter wheat. The growth index at shooting period, yield, grain starch of winter wheat were significantly higher under the sufficient irrigation（irrigation quota for 900 m3·hm-2） than under less-sufficient irrigation（irrigation quota for 600 m3·hm-2）. The differences between two treatments were 19% and 9% for yield and starch content, respectively. No significant differences were observed between two nitrogen fertilizer levels under the same irrigation rates. However, the water use efficiency（WUE） was higher under less-sufficient irrigation than under sufficient irrigation. In conclusion, Irrigation of 900 m3·hm-2 with 30 kg N·hm-2 would be optimum for winter wheat growth and grain quality. |
