Abstract

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 12.57t/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

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
