摘　　要：为探讨生物肥对玉米产量的影响进行了生物肥与复合肥配比试验。在"双行交错"玉米种植新模式下,设置了生物肥+复合肥、生物肥+50%复合肥、只施复合肥、只施生物肥4个施肥处理与空白对照的试验。结果表明:施用生物肥可显著提高穗粒数和单株产量,施用生物肥比空白小区产量提高27.78%;在减少50%复合肥条件下仍保持了较好的产量水平。结论:施用生物肥可保持玉米全生育期生长发育需要的养分含量,可节约50%复合肥,生物肥+50%复合肥施肥方式可在黄淮海玉米种植区进行推广。The combinations of bio--fertilizer and compound fertilizer were tested to explore the effect of biological fertilizer on maize yield. Under the new planting model of ＂Double line interlaced＂, four application experiments were designed, which were the bio--fertilizer and compound fertilizer, bio--fertilizer and 50% compound fertilizer, compound fertilizer only and bio--fer- tilizer only. The results were as follows： The application of bio--fertilizer could increase the seeds per ear and the yield per plant, and the yield of maize applied with bio--fertilizer increased 27.78% than the control. The maize kept a relatively high level of yield under the condition of 500/00 compound fertilizer reduced. Conclusion： The bio--fertilizer could maintain the nutri- ent content needed for growth and development of maize during the whole stages. The application measure of 50% compound fertilizer and bio--fertilizer could save 50% compound fertilizer without much reduction of yield and could be expanded in the maize planting area of Huanghuaihai region.
