摘    要:在氮磷钾基肥供应足量的基础上,采用叶面喷施的方法,研究Zn、Fe、Mo、Co、B、Cu、Se、Mn 8种微肥混合喷施对紫花苜蓿(Medicago sativa L.)草产量和品质的影响,其目的是通过喷施微肥试验,为生产提供不同用途的优质牧草。结果表明:几种微肥处理均可极显著提高紫花苜蓿产草量和叶茎比,极显著提高粗纤维含量,并显著影响粗脂肪含量,促进粗灰分的增加,导致无氮浸出物的降低,但对粗蛋白和磷含量影响不显著。

关 键 词:紫花苜蓿  微肥  产量  品质

Abstract:Based on the ample N,P,K fertilizer supply,adopting the method of spraying leaf surface,the experiments was conducted to investigate the effect of 8 kinds of trace element fertilizers (Zn,Fe,Mo,Co,B,Cu,Se,Mn )mixed spraying on the yield of forage and quality of Medicago sativa.The purpose is to provide the fine pasture for different productive uses through the examination of spraying trace elements.The results showed that spraying trace elements could remarkably increase the yield of forage and the leaf stem ratio (LS),significantly increase crude fiber's contents,markedly affect the crude fat's contents,promoted the enhancement of crude ash's contents and reduced nitrogen-free extract's contents,but the effect of spraying trace elements on crude protein and phosphorus's contents of Medicago sativa was inapparent.
Keywords:Medicago sativa  Trace elements Fertilizers  Yield  Quality
