通过4个试验探讨在冬小麦生长后期叶面喷施不同次数、不同浓度的黄腐酸钾，对不同小麦品种的穗粒数、千粒重及产量的影响。结果表明：在冬小麦挑旗期、灌浆期各喷施1次67 m g/L黄腐酸钾增产幅度最大，与其他供试小麦品种相比，济麦22产量增加最多，比对照增产39.9%，穗粒数比对照增加30.2%，千粒重增加15.0%。高浓度黄腐酸钾对小麦产量有抑制作用，供试小麦品种对高浓度黄腐酸钾的敏感度依次为：济南17＞济麦22＞山农17。

Effect on grain number per spike, thousand-grain weight and the yield by spraying fulvic acid potassium to different varieties and the growth stages of winter wheat were discussed through 4 testes. The results showed that the wheat harvest of the treatment which was sprayed the solution containing 67 mg/L fulvic acid potassium 2 times at lag leaf stage and illing stage was the best. Compared with the other wheat varieties on test, Jimai 22 get the best effect ,the yield increased 39.9%, the grain number per spike increased 30.2%, the thousand-grain weight increased 15.0%. High-concentration fulvic acid potassium will reduce the wheat harvest, the sensitivity of the wheat varieties on test was Ji-nan17>Jimai22>Shannong17.
