商品有机肥和氮肥配施对冬小麦产量及氮肥利用率的影响

Influence of the Combination Application of Commercial Organic Manure and Nitrogen Fertilizer to Winter Wheat Yield and Nitrogen Use Efficiency

施肥是保证作物增产的重要措施。通过田间试验,研究了商品有机肥与不同施用量氮肥配施对冬小麦产量及氮肥利用率的影响,结果表明,有机肥和氮肥配合施用会影响冬小麦的生物量、产量和氮养分吸收及氮肥的利用率,且以每公顷600 kg商品有机肥与120 kg纯氮的配施效果最好。

Fertilization is an important measure to ensure the crop yield. This study researched the effects of the combination application of commercial organic manure and nitrogen fertilizer in the field. The results showed that the combined application of organic manure and nitrogen fertilizer had influence on biomass grain yield, nitrogen fertilizer use efficiency of winter wheat. An admire effect was obtained with combination application of commercial manure 600 kg/hm^2 and N 120 kg/hm^2.
