摘　　要：[目的]探讨复合添加剂在复混肥中的功效。[方法]在田间试验条件下,研究新型花生专用肥对花生结瘤、产量和养分利用效率的影响。[结果]加入添加剂的花生专用肥对花生结瘤的抑制作用较小,促进根瘤发育,加入复合添加剂的花生专用肥的促进效果更好,根瘤数和根瘤干重明显高于其他处理。施用花生专用肥处理显著提高了花生产量,分别比习惯施肥和俄罗斯复合肥处理增产17.1%-21.0%、11.8%-15.7%,花生全株氮磷钾养分积累量均大大高于习惯施肥和俄罗斯复合肥处理。[结论]该研究为新型肥料的研制开发和推广应用提供了参考依据。[Objective]The aim of the research was to discuss the efficacy of compound additive in compound fertilizer.[Method]In filed experiment, the effects of new special fertilizer for peanut on the nodulation,yield and nutrient utilization efficiency of peanut were studied.[Result]The special fertilizer with additive had little inhibitory effect on the nodulation of peanut and promoted the development of root nodule.And the promotion effect of peanut special fertilizer adding the compound additive was better and the number of root nodule and dry weight of root nodule were obviously higher than that in other treatments.The yield in the treatment of applying peanut special fertilizer could significantly increased the yield of peanut,being 17.1%～21.0% and 11.8%～15.7% higher than that in the treatments of applying conventional fertilization and Russia compound fertilizer resp.The nutrient accumulated amount of nitrogen,phosphorus and potassium in the whole plant of peanut was greatly higher than that in the treatments of applying conventional fertilization and Russia compound fertilizer.[Conclusion]The research provided reference basis for the development,popularization and application of new fertilizers.
