黄腐酸有机肥是秸秆为原料，经过专利技术加工生成的天然有机肥料，富含各种矿质营养元素。本试验通过研究黄腐酸有机肥对河南驻马店和新乡2个试验点玉米产量和成产因素的影响，找出黄腐酸有机肥的最佳施用量和施用方法。试验结果表明：施用黄腐酸有机肥对夏玉米增产效果显著，并且随黄腐酸有机肥使用量的增加，夏玉米产量相应增加。综合2个试验点结果，以处理5和处理8为最佳，如果考虑肥料成本，则以处理5效果最佳，即每亩地基施4?kg氮肥、6?kg磷肥、6?kg钾肥、15?kg克黄腐酸有机肥，后期每亩追施4?kg氮肥和15?kg黄腐酸有机肥。对2个试验点影响玉米产量因素的分析结果一致表明：影响玉米产量因素主要表现在穗粒数和百粒重上，穗长、穗粗变化不大。此外，处理6减产，穗粒数减少，百粒重减少或不变，这与化肥中的氮肥用量减少有关，说明氮肥是对玉米产量影响较大的营养元素。

Fulvic acid organic fertilizer mainly consists of fulvic acids from the straw with the related patent technol-ogy, and riched in various mineral nutrients. In order to determine the optimum amounts of fulvic acid organic fertilizer combined application of different amount of fulvic acid organic and chemical fertilizer on corn were studied. The results showed that application of fulvic acid organic fertilizer signiifcantly improved corn yield with the increasing of the ap-plication amount. The comprehensive results of two sites showed that treatment 5 and 8 had the best yield increasing effects in two sites without signiifcant difference. Considering fertilizer and labor costs, treatment 5 was recommended. That means using 4 kg nitrogen fertilizer, 6 kg phosphate fertilizer, 6 kg potassium fertilizer and 15 kg fulvic acid organic fertilizer as basal application, with 4 kg nitrogen and 15 kg fulvic acid organic fertilizer in topdressing period. Two sites analysis results on factors affecting maize yield consistently showed that the main factors affecting maize yield were spike grain number and hundred grain weight, spike length and spike thick changed little. In addition, the yield, spike grain number and hundred grain weight of treatment 6 decreased or unchanged, which may be related with the amount of nitrogen fertilizer reduced. It indicated that nitrogen is the nutrient effects on maize yield.
