摘　　要：通过田间试验研究了富啡酸和锌硒配施对紫花苜蓿草产量和品质的影响。结果表明:单施富啡酸和锌硒都能提高苜蓿的产量,富啡酸增产的效果强于锌硒微肥,富啡酸和锌硒配施(NPK+FA+Zn+Se)对紫花苜蓿增产效果最好,产量达到12.57t/hm2,比对照增产57.13%,且该处理紫花苜蓿茎叶比最低,有利于提高苜蓿的粗蛋白质含量。富啡酸对提高紫花苜蓿粗灰分和无氮浸出物含量、降低粗纤维含量的作用大于锌硒微肥,但锌硒微肥对提高紫花苜蓿的粗蛋白质和粗脂肪含量的作用大于富啡酸,富啡酸和锌硒微肥配施比单施能获得更高的品质。The effects of fulvic acid （FA）,Zn and Se combined application on alfalfa yield and quality were studied.The results showed that both FA and Zn and Se combined application could improve the yield of alfalfa,and the increasing yield effect of FA was better than that of Zn and Se combined application,and the increasing yield effect of FA and Zn and Se combined application treatment （NPK＋FA＋Zn ＋Se） was the best,and the yield was 12.57 t/hm2,higher by 57.13％ than that of CK,and also could reduced stem/leaf ratio.The effect of FA application treatment on increasing alfalfa＇s crude ash and nitrogen free extract contents,reducing crude fiber content was better than that of Zn-Se combined application.However,the effect of Zn and Se combined application treatment on increasing alfalfa＇s crude protein,and crude fat contents was better than that of FA applied treatment.FA,Zn and Se combined application could get better alfalfa quality than that of FA,and Zn and Se single application
