摘　　要：[目的]通过田间小区试验,研究叶面喷施腐植酸水溶肥对冬小麦生长、产量构成因素及经济效益的影响。[方法]以徐麦35为材料,采用叶面喷施水溶肥的方式,在小麦返青期、拔节期和孕穗期各喷施1次腐植酸类叶面肥,得出施用效果。[结果]腐植酸水溶肥能增加小麦的穗数、穗粒数和千粒重,增产率达10.58%,增产效果显著,产投比为5.76∶1,经济效益明显。[结论]安徽华润公司生产的含腐植酸叶面肥可以在凤阳县大面积推广应用。[Objective]The effects of leaf spraying humic acid water-soluble fertilizer on growth,yield composition and economic benefit of winter wheat were studied by field plot experiment.[Method]Using Xumai 35 as the material,the humic acid foliar fertilizer was sprayed once in wheat regreening stage,jointing stage and booting stage,and the application effect was obtained.[Result]Humic acid water-soluble fertilizer could increase the number of spikes,number of grains per spike and 1000-grain weight of wheat,the yield increase rate is 10.58%,the yield increase effect was significant,the yield to investment ratio was 5.76∶1,and the economic benefit was obvious.[Conclusion]The leaf fertilizer containing humic acid produced by Huarun could be widely applied in Fengyang county.
