为了找出黄腐酸有机肥在冬小麦上的最佳用量和施肥方法，本试验研究了不同用量的黄腐酸有机肥对新乡和驻马店2个试验点冬小麦产量和成产因素的影响。试验结果表明：施用黄腐酸有机肥对冬小麦增产效果显著。综合2个试验点结果，以处理3、处理4效果最好。如果考虑肥料成本，则以处理3的施肥配方和施肥措施最佳，即基施氮肥90千克/公顷，磷肥90千克/公顷，钾肥90千克/公顷，黄腐酸有机肥150千克/公顷；追施氮肥90千克/公顷，黄腐酸有机肥150千克/公顷。2个试验点影响产量差异的主要因素相同，都表现在亩穗数和穗粒数上，基本苗、最大分蘖变化不大。此外，处理5减产，但与处理1(C K)差异不显著，说明施用黄腐酸可以降低化学肥料用量。

In order to determine the optimum amounts of fulvic acid organic fertilizer combined with application method, different amount of fulvic acid organic fertilizer were studied on wheat. The results showed that the applica-tion of fulvic acid organic fertilizer could signiifcantly improve yield. The result conducted at Xinxiang and Zhumadian showed that treatment 3 and 4 induced the best effects. Considering fertilizer costs, treatment 3 was recommended. That means using 90kg/hm2 nitrogen fertilizer, 90kg/hm2phosphate fertilizer, 90kg/hm2potassium fertilizer respectively and 150kg/hm2 fulvic acid organic fertilizer as basal application, with 90kg/hm2 nitrogen and 150kg/hm2 fulvic acid organic fertilizer in topdressing period. Further alalysis showed that the main factors were spike grain number and hundred grain weight. In addition, althogh the yield in treatment 5 decreased, there was not signiifcant difference compared with treat-ment 1(CK), which implied the application of fulvic acid could reduce the dosage of chemical fertilizer.
